Advanced Microeconomics Essay Question 1: Consumer Theory 1.1: In both the Marshallian and Hicksian consumer optimisation problems, it is assumed that consumers are supposed to be rational. The main focus of these problems are cost minimisation and utility maximisation, which play a huge part in consumer demand, but in real life, these are not the only problems that are considered. Also, it is assumed that every consumer’s indifference curve for two goods would be the same – they are very generalised models, and do not take into account other factors. For example, not many consumers would spend their entire budget on said goods – one thing to consider would be a consumer’s marginal propensity to consume and save. Though both of the problems provide a framework and model of consumer decisions, they are not plausible when applying them to real-life terms, because we have imperfect knowledge. 1.2: The expression given in the question, is the rearranged derivative of the Hicksian demand being equal to the Marshallian demand, when income from the budget constraint is equal to minimised expenditure, whereby m=ep, ÃŽ ¼. This is given by: dDdp= dHdp- dDdm . dedp using m = e. Shephard’s Lemma provides us an alternative way of deriving Hicksian demand functions, using e. It is given by: dedp= x* It is important to note that e is strictly increasing in p, due to Shephard’s Lemma, and x* 0,by assumption. Substituting this into the above expression gives: dDdp= dHdp- dDdm x*  This expression now represents a complete law of demand, as it has combined both Marshallian and Hicksian demand, whereby income from the budget constraint of Marshallian demand, is equal to minimised expenditure of Hicksian demand. Therefore, it has maximised utility and minimised cost simultaneously, to create an optimal quantity of demand in x*. The first term, dDdp, means that Marshallian demand (maximising utility) increases, relative to the price of the good. dHdp represents the Hicksian part of the expression, whereby expenditure is minimised, relative to the price of the good. Question 3: Adverse Selection, Moral Hazard and Insurance 3.1: Insurance markets are needed when risk is present. Risk occurs when there is uncertainty about the state of the world. For example, car drivers do not know if they will crash their car in future, and suffer a loss of wealth – so they would purchase insurance to eliminate this risk of loss, and protect them if they were to ever crash their car. Agents (buyers of insurance) will use insurance markets to transfer their income between different states of the world. This allows insurance markets to trade risk between high-risk and low-risk agents/states. These can be described as Pareto movements. A Pareto improvement is the allocation, or reallocation of resources to make one individual better off, without making another individual worse off. Another term for this is multi-criteria optimisation, where variables and parameters are manipulated to result in an optimal situation, where no further improvements can be made. When the situation occurs that no more improvements can be made , it is Pareto efficient. A condition for efficiency is the least risk-averse agent bears all the risk in an insurance market. If a risk-averse agent bears risk, they would be willing to pay to remove it. A risk-averse agent has a diminishing marginal utility of income; whereby his marginal utility is different across states, if his income is different across states. The agent would give up income in high-income states, in which his marginal utility is low, to have more income in low-income states (e.g. bad state of the world causing a loss of wealth), where his marginal utility would be high. If the insurance market is risk neutral, they will sell insurance to the customer, as long as the payment received is higher than the expected value of pay-outs that the insurer is contracted to give to the customer in different states of the world. Whenever the agent bears some risk, unexploited gains from trade exist. Absence of unexploited gains from trade is a requirement in an efficient insurance market, therefore the situation must arise, whereby the agent’s income is equalised across the states of the world. A risk neutral insurance company can charge a premium to equalise the agent’s income across states of the world, in the best interests of the risk-averse agent. Also, for an insurance market to be  efficient, a tangency condition is implied. The tangency of the indifference curves of a risk-averse agent, and a risk-neutral agent, is where efficiency occurs. At this point, one cannot be made better off, without the other being made worse off (Pareto efficiency). However, an insurance company will never be completely efficient in real life, as information asymmetry exists. The first type of information asymmetry to arise in an insurance market is moral hazard, whereby the actions that an agent may take after signing the contract cannot be observed. This gives the company a trade-off decision between giving full insurance or offering incentives for the agent. Full insurance is first-best in the absence of asymmetric information, when the insurance company is risk-neutral and the agent is risk-averse. However, if the agent is fully insured by the company, they have no reason to prevent a bad state of the world from happening. To solve this problem, the insurance company will not offer full insurance, in order to provide the agent with an incentive to avoid losses. The second type of information asymmetry to occur in an insurance market, is adverse selection. This is when the agent has private information about his risk type and characteristics, and agents in the market are heterogenous. As the insurer doesn’t know which agents are high-risk or low risk, the company will not offer different types of full insurance to match risk-types, as high-risk agents will prefer contracts that are designed for low-risk agents. To solve this, the insurer will offer low-risk agents less insurance – this ensures that high-risk types do not have the incentive to choose a contract for low-risk customers, as they will want more insurance, because they know they will need to claim more. This ensures that the insurance company maintains non-negative profit, as high-risk individuals cost more to insure. However, these solutions carry agency costs, because the result is less efficient than if symmetric information was present. I believe that risk neutrality of an insurance company is a sufficient condition for insurance to take place. Insurance companies are risk-neutral to maximise expected profits, therefore as the principal, will design contracts to achieve this, as well as making certain that the agent picks the desired effort (i.e to prevent a bad state of the world) for that contract, and to make sure that the agent even picks the  contract in the first place. Making sure incentives are compatible, and ensuring participation by the correct risk types, are constraints on maximising expected profits. If an insurance company was risk-averse, without the availability of symmetric information, they cannot differentiate between different risk-types, and therefore would not want to take on the risk of possible high-risk agents buying low-risk contracts. They would charge a higher premium to offset this, which would discourage low-risk customers to sign a contract with the company, as it would not be maximising their own utility. This would lead to a missing market, where trade would be prevented, because other risk-neutral companies would offer better contracts, and they would be able to steal all the low-risk customers. The magnitude of this would depend on the number of low- and high-risk people in the population. This leads me to believe that risk neutrality is also a necessary condition for insurance to take place. 3.2: An insurance company will sell a policy, c, r, if it makes non-negative profits, then:  Ã¢â€ â€™ r-pic ≠¥0,  where c = payout, pi = probability of the loss state, r = premium. Competition in the market drives profit down to zero, therefore r-pic = 0 in equilibrium. For the contract to be at equilibrium, it must satisfy two conditions: the break-even condition, whereby no contract makes negative profits; and absence of unexploited opportunities for profit, because if there was a contract outside of the offered set, with non-negative profit, would mean the offered set is not in equilibrium. If all agents are homogenous, if all agents face the same probability of loss, pi=p, insurance companies would know each buyer’s pi. The firm must maximise each agent’s utility subject to the firm breaking even. This would be at the point of tangency of the agent’s indifference curve and zero-profit constraint. This would be in equilibrium as another profit-making polic y could not be offered. Therefore, as they can observe agent’s risk types, they can offer different policies, to different types: ÃŽ ¸i= ri, ci. It follows that each is offered full and fair insurance. In real life, heterogeneity is usually the case. This is when pi varies with all individuals. Assuming that there are two types: high-risk types, H, and low-risk types, L, where the probability  of loss for H is higher than for L. Individuals know their own probability of loss i=H, L, but insurance companies are unable to observe this. In this case, there are two different kinds of equilibria that insurance companies could opt with: the candidate pooling equilibrium and the candidate separating equilibrium. The pooling equilibrium is where all risk types buy the same policy. In contrary, the separating equilibrium is based on each risk type buying a different policy. In the pooling equilibrium, if both H and L risk-types choose the same policy, the probability of loss is p and the probability of no l oss is 1- p. Therefore, the slope of the ‘aggregate fair-odds line is -1-pp. The pooling contract must lie on this line to be in equilibrium, to ensure the firm breaks even exactly. The contract must also ensure both types want to buy it – it must take both L and H to higher indifference curve than the indifference curve they would be on if they stayed uninsured. Agent L ends up below his fair odds line, and H above his, which means L pays more than expected costs, and H pays less – both pay the fair pooled premium, but H claims on the policy more. So if L prefers to buy the contract, so will H. This leads me to believe both L and H will be able to get full insurance, though it’s not completely fair, as the firm does not need H to choose a different policy to remain breaking even. However, this brings to mind the notion that if full insurance is offered, the agent will not have the incentive to prevent a loss state. Therefore, less insurance will probably be offered, and as both risk types are paying the same premium of the same policy, neither will receive full insurance, as it impossible to differentiate between the two – they will both choose the same policy offered. In the separating equilibrium, one contract would be offered to L, and another to H. Each risk type must prefer the contract designed for that type (i.e. the incentives must be compatible). The contracts offered should give each type the highest possible utility, subject to the firm breaking even. If full insurance contracts were offered to both L and H, where their respective indifference curves are tangent with their respective zero-profit constraints/fair-odds lines, low risk customers would prefer the policy designed for them, but high-risk customers would also prefer the same policy, not the policy designed for them. So they would not both be offered full insurance, as this gives rise to the problem of preventing H from imitating L – low-risk agents are cheaper to insure for the firm (claim less  often) so they get a better rate. Therefore, instead of offering L full insurance, they are offered C, which is still on their fair odds line, but on a lower indifference curve, still ensuring the zero-profit constraint. Now, if the high-risk agents were to choose between the policy designed for them, and C, they will choose the policy designed for them, because they prefer to have more insurance for less money. So, in conclusion, in the separating equilibrium, high-risk (H) customers receive full insurance, and low-risk (L) customers only receive partial insurance – they pay the price to prevent H from imitating them. L is worse off than if there was symmetric information in the market, but no difference to H.

Effect of Political Instability on International Trade

Effect of Political Instability on International Trade ABSTRACT Regarding political instability in African Country, it is also undeniable that African continent has gone through some tough situation during fifty years past. But the fact is almost African cases regarding political instability the major cause of problem is leadership. And because of this African freedom heroes come to dictators, while African natural resources, politics of elimination and scarcity to slope the balance of authority continues to control the public globe. Moreover, these difficulties have been pointed out due to ordinary Africans leaders who already edged and they dont want to retire. Political instability in Africa may be obliged much of its reason to internal factors, though the interpenetration of internal and external aspect especially geo-political and economic comfort of the international community always play a major role in undermining the vey procedure and society that are expected to care for democracy and to inspire a sense of stability for community development in Africa. In combination to such issues as unequal development, poverty, disease, violence and the scheming tendencies of the local best, political and economic stability in Africa is continually under threat is though not emanating from inside the continent but as of external interests whose dryness for African resources, continue to figure the dynamics in areas connected to governance. Resources in Africa if fine managed are able of providing for its entered population, therefore the potentials for an extra stable environment, nevertheless, it is well recognized that stolen riches from Africa n frequently end up in banks abroad. [African Focus Bulletin, 2006], exist it money stolen by the political selected (case of Mobutu of Zaire, Abacha of Nigeria, and Moi of Kenya, just to state a few or the current Kibaki regime Anglo-leasing scandals in Kenya), they still end up in banks in the western capitals. Effect of Political Instability on International Trade in Africa countries What are the effects of political instability has on International Trade in African Countries? 1.0 Introduction The International Day of peace which was established by a U.N resolution in 1982, and is marked every year on September 21, is a global even whose activities are significant in highlighting the worldwide efforts towards conflict resolution and peace building.[Diaspora 2008] This day is more concern with African continent which most of place conflict have taken place. That there are troubles in Africa for quite decades even after several countries in the continent went through change from colonialism to self-government, is not a deniable reality. 2.0 Political Stability in Africa As described in the first essay, country with political stability, donors will trust that country and they will invest a lot. The larger company can transfer they investment to that country, also investor can return their profit back to the communities, and will boost the sectors which it almost died of is in bad shape. Country with political stability economy will grow; this is due to investor will invest more as long as they feel secure on their investment. People of the respect country will be benefited by get knowledge which transferred from the investors. Countries that can produce a product at the lowest possible coast will be able to gain a larger share in the market. Therefore an incentive to produce efficiently arises. This will help standards of the product to increase and consumers will have a good quality product to consume. More employment could be generated as the market for the countries goods widens through trade. International trade helps generate more employment through the establishment of newer industries to cater to the demands of various countries. This will help countries bring down their unemployment rates. However it could lead to a more rapid depletion of exhaustible natural resources. As countries begin to up their production levels, natural resources tend to get less. 2.1 Assessment of political stability on international trade in Africa 2.1.1 Peace and Stability Tanzania is one example of the country among sub Saharan Africa which economic and political stability is stable. Multi party democracy adopted in 1992 has not disturbed the peaceful political climate of the country. This is why FDI are very interested with country situation and invest a lot on different sectors, such as Mining Industries, beverage industries, telecommunications companies, NGOs and so on. 2.1.2 Labour skills and availability International Trade is doing well; this is because of access to skilled labour which is a key priority for companies competing in African economies. Tanzania has a long term commitment to make sure development on training and educated specialists is going well. The government put more budget of education sector in order to improve education and improve human capabilities and encourage technology transfer as a precondition for enhancing productivity of investment and attaining the desired level of competitiveness. [http://www.tic.co.tz/] 2.1.3 Private sector development Tanzania has notable itself among of few African countries that have thoroughly transformed their economies. Achievement of these reforms is imitated in the countrys strong macroeconomic fundamentals every time increasing growth rates, consistent falling inflation and increasing inflow of FDI. One of the factors that contributed to this achievement is the countrys unwavering commitment to build a strong private sector. [http://www.tic.co.tz/] 2.1.4 Infrastructure Facilities Tanzania put infrastructure as one of the key investment drivers of country is trying very hard to improve. 2.1.5 Stable Macroeconomic performance Tanzania had been concerned out successful economic and structural reforms, which have enhanced economic performance and continual growth. These achievements are based on concrete foundations of political and economic reform carry out by the government since 1986, placing Tanzania in a point where a prolonged stage of high GDP growth rates is predictable. In additional, Tanzania has a constant fiscal regime with sustainable rank of inflation.

But the fact is almost African cases regarding political instability the major cause of problem is leadership. And because of this African freedom heroes come to dictators, while African natural resources, politics of elimination and scarcity to slope the balance of authority continues to control the public globe.

African governments are run in ways that have been staring as far from the modern western state structure [Osei Tutu, 2004] Domestic issues play a major role in the changeover. These domestic issues frequently variety as of corrupt rulers, repressions, a majestic legacy, distended states, and inadequate political structures and an obliteration of democracy [diamond, Linz, and Lipset 1989; Diamond and Plattner 1999]. However, the international framework often plays a vital role in both the changeover in general and the attendance of violence in exacting [Lupo, 2004] 3.2 Africans economy and political instability Despite the miserable predictions, most African economies are exploiting well even though a few country cases are still experiencing hard times in terms of political stability, economic growth and challenges posed by poverty and diseases, trade quantity and foreign investments have enlarged over time. However the political instability in Africa, which as well underpins the economic development frequently, has strong associates to internal and external distinctive interests time and again. Africas resource in this case has never been its approval, but a nuisance. These is no justification for the under development of the continent even as it sits on huge natural resources. [Rodney, W. (1981)] 3.3 Africa Political violence and political instability As an effect, the legitimate frameworks and state institutions have been meddle with, in order to generate an uneven play field alongside the opposition. Some of these procedures have seen irregular violence during electioneering era, leading to political instability. However the level of violence and the mode in which they are perpetrated differ from country as the recent elections in Uganda, Nigeria, Kenya and Zimbabwe can illustrate. [Mahamoud, 2006:15] With a lot of countries holding their third or fourth multi-party elections, internal power struggles have engaged a cruel dimension, thereby intimidating the very existence a lot of countries. Since the beginning of multi-party democracy in mainly African countries electoral procedures have been go together with political violence, as part of the democratisation process [Lupo, 2004; Huntington,1991]. Most violence is such cases are often state supported, to the advantage of the incumbent, while a variety of groups that hike for state power also intensely hired violence, in the form of informal groups, militias and gangs. In the circumstance of all the violence, it is the normal people who loose out in terms of lives and property. The calamity is that the political conflict is not about substitute political programmes that could address the main problems such as poverty, disease and illiteracy, but only a fight over who has right to use the state resources.[country-details] 4.0 Analysis 4.1 International Trade within Political Instability in Africa Country with political instability will be hard for investor to invest. This is due to situation is not good for them. However other investors are attracted with situation and take advantage for the situation by starting to make business. The International companies who are suppliers of guns and weapon will their time to sell and pray to God situation remain the same for sack of the business. People killed each other but investors they dont care as longer they doing business. In other part they may support that conflict by provide some money for other part to make them be able to fight other side and war continue. So as we can see one side they will be in trouble due to the investments been destroyed in the war because of political instability, and other side they will be benefited. Some of countries remain poor because of political instability. This could be ethnic tension, tribalism or all out war. Country such as Zimbabwe, Somalia, Rwanda and others they involved with long-term conflicts, they have a little chance of developing. Some countries also crash ethnic divides that are a constant distraction de-stabilizing the region and end up of discouraging investment, one example is Sir Lanka. 4.2 Assessment of political instability on international trade in Africa There are often political factors involved in why some of African country such as Zimbabwe, Somalia Sudan, Ethiopia, and Burundi and other suffers. This is due to bad government. Governments need to do a lot of things to encourage development, they need to build and maintain infrastructure and raise and spend finance wisely on the right projects. When governments are inept at managing infrastructure, development is impossible. Nobody wants to build a factory in a city where the power could go out at any time. Zimbabwe and other mentioned country should do the same and also needs to set up their laws and business practices in a way that encourages investment. Some of the Factors which affect international trade operation in Africa Corruption International Trade Trade Laws Political Instability Corruption Corruption is something which frustrating, disheartening and fundamentally disempowering investors. When government become loose on the simple process such as customs officials which everyone knows about, it end up of make life difficult to investors and business in general. In African countries this is common and is needs to be stopped and my country tried very hard to make it happened. [makewealthhistory n.d] Trade Laws Trade Laws it is largely a political matter. Sir Walter Raleigh famously said whosoever commands the trade of the world commands the riches of the world and hence the world itself Political instability Political instability plays a role in why some countries like Somalia and others remain poor. This could be ethnic tension, tribalism, or all out war. Needless to say, countries with long-term conflicts such as the ones in Somalia or Afghanistan have little chance of developing unless otherwise. [makewealthhistory n.d] I tried to make research for some of the African countries as follow SOMALIA Somalia involved with war since of Siad Barres regime in 1991. A lot of people in Somalia suffered due of conflict which causes long-term impact of disturbed peace, security and stability also development. This conflict cause a lot of problem and continued loss of life which end up of intermittent fighting, famine, displacement of persons and the resultant flow of refugees. The conflicts affect also neighbors countries such as Kenya, Ethiopia and Djibouti, due to proliferation of small arms, huge influx of refugees many of whom are ex-soldiers its criminal target. Overall Somalia politically is unstable. After the collapse of the Somali government various factions decided to vie for control of Somalia, which resulted in chaos, clan warfare, and interplant fighting. Although Somalia is not as lawless as it was at the time when Barre as ousted Somali factions still continue to fight for control of the territory. Somalia is a much divided national that lacks any sense of cohesive government and therefore there is no real overall ideology of the country. Somalia is attempting to stabilize many of the internal conflicts that continue to prevail in the country along with attempting to create a political ideology and a foreign policy. Political uncertainty its like nightmare to investors. It does disturb FDI (foreign Direct Investment) flow of their investment plan together with private sector and economic growth because government owned those public sector units as well. If happened that country faced unstable political, many this goes wrong. In situation like this no investor will be interested to invest in Somalia Land. This is due to political instability which put FDI in hard situation to invest. This conflicts cost the horn Africa countries deeply in terms of security due to increase of groups of arms, due to influx of refugees and lost trade. However international and regional organizations such as the UN (United National) and IGAD (Intergovernmental Authority for Development) have come between for the aim of bring peace in the war torn country. According to [BBC conversation 29th December 2010 thru radio] American tried to make peace there but they failed due to Somalia arm group come together and fight American. Somalia is one of the nations that has struggled and still does today in order to function well. It is one of these are rare places where there is ongoing civil war and it has no central government. Somalia is in a state of anarchy because it had problems after their president got assassinated in 1969, it has many economic problems, and native clans in Somalia are constantly fighting with their foes. If Somalia can solve these problems, it will be able to function very well and gain a government that will suite them well. UGANDA Another example is Uganda country. Iddi Amin President by then ruled the Government to manage all of Asian investors properties and commanded them to leave the country in short notice. This was applied to all whites investors, and even rich black. This was real bad to investors. Due to dictatorship mode of government the country came down economically and eventually to poor position. After war he decided to attack neighbor country which is Tanzania and caused a war. Situation become worse, Tanzania and Uganda war rendered Tanzania economy to fall drastically. It takes time for Tanzania to recover due to many country resource used on that war. Frankly it will be difficult for investors to withstand in violence countries. Economic growth needs political stability which will attract investors to invest in a particular country. BURUNDI Another example is Rwanda and Burundi. People killed and neighbor countries also affected due to the guns and other dangerous tools goes to them and used for robbed and so on. Rwanda war was so bad because it was tribe war (within Rwandas people). It was very difficult for investor to invest there or do international business there. They so cruel killed themselves, kill religion leaders and so on. Lets look at Zimbabwe; Mugabe makes things worse thereby take away the investors investments which most of them was farm. Those investors were doing very well on that sector. Mugabe was trying to divide the land to the Zimbabwe farmers without knowing that they dont have money to invest there and at the end they fail to run the business. Look at Zimbabwe now is terrible. There was violence which has badly hurt the commercial agricultural sector the traditional cause of exports and foreign exchange and the provider of 400,000 jobs, revolving Zimbabwe into a net importer of food products. The EU and the US give food aid on humanitarian foundation. Badly needed bear from the IMF has been suspended as of the governments arrears on long-ago loans and the governments unwillingness to ratify reforms that would become stable the economy. The Reserve Bank of Zimbabwe normally prints money to fund the budget deficit, causing the official annual inflation rate to rise from 32% in 1998, to 133% in 2004, 585% in 2005, passed 1000% in 2006, and 26000% in November 2007, and to 11.2 million percent in 2008. In the meantime, the official exchange rate chop from approximately 1(revalued) Zimbabwean dollar per US dollar in 2003 to 30,000 per US dollar in September 2007[ country-details n.d] Many people in Zimbabwe they dont have jobbed, currency is in bad shape due to inflation. Before Mugabe took land from investor, people were employed on that industry, the difference from now there is no job due to those who given that land they dont have money to run the business. Zimbabwe is other country which has political problem. Zimbabwe is the second highest HIV infection fate, per capita, in the world. Zimbabwe has experienced the breakdown of law and order, unemployment of 65%, inflation104%, the collapse of the economy and the health delivery system. Human rights abuses in the form of violence and rape have continued unabated and are carried out with impunity by the ruling party activists. Voices against basic human rights abuses speak at great personal risk. It has been established that the effects of the current situation have impacted negatively on the health and well being of the people through increased stress, little or no access to primary health care facilities, unemployment, hyper-inflation and a general sense of helplessness and hopelessness. All this is due of political instability. [gateway n.d] Zimbabwe there are group of people have good life, but majority are not enjoying anything. They have very difficult life. Most of people they live in poverty and cause of anger among them towards government. These anger cause political instability and end up of forming crime revolutions and so on. [wiki.answers n.d] INFLATION-ZIMBABWE Zimbabwe Economic Overview The government of Zimbabwe faces a wide variety of difficult economic problems as it struggles with an unsustainable fiscal deficit, an overvalued official exchange rate, hyperinflation, and bare store shelves. GDP -real growth rate -6.2% estimated in 2008. GDP (official exchange rate): $4,397 billion Note: In 2009 the Zimbabwean dollar was taken out of circulation, making Zimbabwes GDP at the official exchange rate a highly inaccurate statistic.[Source: C/A World Factbook] http://www.country-details.com/africa/zimbabwe-economy.php Transition to a market economy Before Investor decide to invest to any country especial African country always they tried to check of follow Gross National Income (GNP) GNP helps to measure income generated together by total domestic production towards as the international trade production activities of local companies. Gross Domestic Product (GDP) GDP is the broadest measure of economic activity for a country. GDP helps investor to assessing countries in which the output of the multinational sector is a significant share of activity. Improving the Power of GNI GNI is a robust estimator of an economys absolute performance. Here international manager has to be careful because GNI can mislead when he/she tried to compare countries. For example, manager to compare economic power of USA and Tanzania will not give manager a good result. So in order for manager to get good view should adjust it for taken the number of people in that country, their growth rate, and their cost of living also economic sustainability. Per Capital conversion Manager will use this indicator to which helps to explain an economys performance according of number of people who lives in such country. Purchasing Power Parity Purchasing Power Parity (PPP) is the number of units of a countrys currency required to buy the same amounts of goods and services in the domestic market that one unit of income would buy in the other country. [Daniel, Sullivan et. al 2009pp186-202] 5.0 Effect of Political Instability Opportunities could be caused by political instability 5.1 Conflict resolution and peace building initiatives In terms of conflicts in Africa, many hot spots are recovering, and making big leaps towards peaceful coexistence. Even though there are some pockets of unresolved cases like Somalia, Darfur, Congo and Northern Uganda among others, there are encouraging examples such as Sierra Leone, Rwanda, and Southern Sudan. In this context Africa is undergoing a complex process of multiple transformations. Solution to some of these cases has been found from within, coupled with external support. For this reason, it can be argued that part solution to the conflict situation and political instability in Africa lies in the west. More specifically is for the western governments to address the issue of arms manufacture and sale of arms, weapons to Africa and to address the conduct of their multinational involved in extractive activities at the expense of African lives. On the same breath, we cannot talk of health problems in Africa when countries in the west have not seen the sense and subsequent impl ications of dumping hazardous technologies and products in Africa 5.2 International Trade in Africa Some of the country they take advantage of the political instability situation to make money by doing international business in that such country. In both situations, political change creates systemic risks that impact all firms whose activities are affected by the political system. System changes dont necessarily create political risks that reduce potential profits. Elections and policy shifts can create opportunities for foreign investors. For example in 1990s a newly elected government in Argentina initiated a radical program to deregulate and privatize the countrys state-centered economy. Investors who accepted the risk and pursued the resulting opportunities prospered as Argentina became more democratic. There is one case in our International Business model talk about china. That case trace about the development of China, where political change has created opportunities in several areas, including market potential and performance. This of course, that taking advantage of such at tractive opportunities entails taking risks in a country where political and legal complications still pose roadblocks to profitability.[Daniel, Sullivan et al (2009) pg155] When other countries suffer of political instability, other countries enjoy that situation very much. Lets say country faced political instability and happened there is a war, some of international companies from other country they start to do business by selling guns, and other things which needed in situation like that. The neighbour countries get advantage of when refugee run to them, they get support from international support programme. The people of such neighbour country they will be benefited by get food, clothes, and other human needs thru refugee. However those neighbour countries may suffer due to refugee may transfer the conflict in that country. Unemployment When country faced political instability unemployment rate will be high, and country will not be able to offer job to the people. So when investors who they ready to take risk move to that country will be easy for them gets cheap labor. People they dont have job and they need money means they will do any kind of job to get money. However countries that are unable to create jobs for their citizens create a risky business environment. So investors whose will take risk to invest in such country must take precaution for robbery and thief due to people are desperate to get money. Generally, people out of work and unable to find jobs depress economic growth, create social pressures, and provoke political uncertainty. Inflation Inflation cause rise in prices measured against a standard level of purchasing power. Country in political instability inflation will be high and the investor who doing there they have power to set their price (high) and consumer they dont have choice. Life will be expensive and investor who doing business there are benefited with high price of commodities. People they work to them and get salary and at the end of day they give back that money to them. This is to say foreign will be able to transfer resources to home country indirect. Debt The debt for the country which faced political instability growing because government dont have money, and end up of borrows money from the financial institution. This will be benefit to those countries which hold those financial institutions such as IFM and so on. Income distribution GNI or PPP (Purchasing Power Parity) will be low due is calculate with which income the average person earns. Country with political instability not everyone is average, neither indicator tells us what share of income goes to what segments of the population. So the big share will go to foreigner whose they have big share of money, and this will be benefit to them.[Daniel, Sullivan et. al pp196-203] Production factors move Capital especially short-term capital is the most internationally mobile production factor. In country with political instability companies and private individuals primarily transfer capital because of differences in expected return. This situation cause of transfer capital back home or to another country and will be benefit to foreigners due to some of country when foreigner came to invest, government allow them to make business for the first three years without of paying tax. The countries with political instability foreigner advantage of this situation and invest for only three years without tax and move to another country. This happened because they not secure with political situation. Analyzing Risk In between political instability, one country risk may be another opportunity to other country. For example companies which provide security services such as guard services, alarm systems, insurances and guns may get the big opportunities of sales where the victim country suffer in war.[Daniel, Sullivan et. al (2009)p 502] 6.0 CONCLUSION Finally the research has been done accordingly by the guidance of the lecturers and my family members. Thanks to be them, without forgetting my fellow students for their corporation. 7.0 RECOMMENDATION An African countries leader has to make sure political in their country is stable so that FDI can transfer they technology, skill and knowledge to the local people thru International Business.

Expansionism overseas in the 1800’s became a very indispensable factor to the United States we know today. The issue of acquiring overseas territories in the 1800’s was very controversial because many citizens felt it was â€Å"un-American† because the U.S itself went through that with the colonization of Britain. However, the government did not consider that when taking into account the interest that came with taking these lands. Economically the Philippines gave the United States potential access to Chinese markets and they also saw advantage of the cheap raw materials in Latin America. Militarily, because the merchant ships were unarmed and carried all their products therefore its required military presence for protection. Also the United States found they competing against France, Germany and Britain, which had the largest navies in the world. The U.S also felt that their presence in the pacific would give them power of the port of Hawaii which was used a re fueling stop for ships headed to Asia. Another very important factor with the expansion overseas was the culture that being taken to them. Many Americans felt superior to other people in the work because the Christian religion made them morally better than everyone else. Due to that fact, missionaries were sent o these countries so they can covert and adapt to the culture and become more â€Å"American and white† and this led to the boxer rebellion in china. Economically the United States was trying to override the rest of the world. Back then and even today people around the world see the United States as a country with money and a land of opportunities. Industrialization in the late 1800s increased the need to trade with other countries. Nothing was dependent on man but instead... ...t to the climax, which later on they did. Even though most of those territories were lost the U.S still managed to keep the relationship it has with other countries. The United States and the issue of acquiring land overseas was not at all something easy to do. From being a weak nation to becoming more economic, militarily and morally superior whom they did accomplished. Even though this concept of expansionism overseas was displayed as a good thing it was truly a hard task to accomplish. Many other countries were willing to go to war with the United States for the territories but even then the U.S still came out reigning successful. Trade was really the main reason for this, to try and find a new way to have open markets and develop allies with other countries, which ultimately and even still is imperative to have in order to have a lot of income for the country.

Terrorists and Personal Weapons :: Terrorism

Terrorists and Personal Weapons Personal weapons fired at short ranges are the primary weapons of terrorists as well as the police officer or soldier fighting against them. One of the most important facets of personal weapons is that they have changed little since the 1940s. They have not been affected by the technological revolutions of nuclear, electronic and aerodynamic guidance and control systems. The weapons may be smaller and lighter with more advanced sights, but the ranges and rates of fire have changed little. The most significant change in personal weapons is most likely the controlled burst. The controlled burst is a system of sustained fire where bullets are fired in short, fast groupings of three. These three round bursts conserve ammunition and also give more effective fire for normal use. Another important development with the ammunition is the creation and use of caseless ammunition, which eliminates the need to eject a cartridge. Plastic ammunition has been designed primarily for training but could be effective for terrorists. If a gun made up completely of non-metallic parts, then plastic bullets would be desirable in evading detection at airports. While some terrorists employ the use of assault rifles, light-machine guns, sub-machine guns and even shotguns, the pistol is still the most popular. Revolvers and self-loading pistols are used because of their size and ease of concealment. Pistols can be carried in a pocket or a hip or shoulder holster, leaving both hands free until it becomes necessary to draw the gun. Armor-piercing missiles are used increasingly on attacks of both armored vehicles and the walls of buildings. They have had little success against vehicles, however, because they do not usually achieve a clean hit at the right angle in the right place, which is essential for effectiveness. Arab terrorists use the hand-held surface-to-surface Russian RPG 7 missile most commonly, and oftentimes these weapons have been largely provided to Arab governments who then can pass them on to terrorists. Terrorists can also use mortars in their attacks. Improvised mortars are extremely easy to make but can be inaccurate and unreliable, and so accidents are unavoidable. Most suitable for terrorist use are light mortars. A popular light mortar is the British 51mm Mortar, which weighs 6.25 kilograms and (its bomb weighs only 0.9kg). It has a range of 800 meters and a projected error of 2%. The use of anti-aircraft missiles by guerrillas to shoot down helicopters and other aircraft has increased.

Basic Transistor Physics Essay -- physics electronics transistor

The first transistor was demonstrated on Dec. 23, 1947, at Bell Labs by William Shockley. This new invention consisting of P type and N type semiconductive materials (in this case germanium) has completely revolutionized electronics. Transistors quickly replaced vacuum tubes in almost all applications (most notably those in discrete logic). Today when we think of transistors the first thing that comes to mind is computers. Advances in transistor technology and manufacturing processes as well as new materials being used for the semiconductor matrix and wiring have led to smaller, faster, cheaper, lower power transistors. Some of the basic principles behind semiconductor behavior and the restrictions currently faced by modern transistors will be discussed in the following pages. Transistors are composed of a P type (positively doped) and N type (negatively doped) semiconductor material. These P-N junctions are the heart of both BJTs (Bipolar Junction Transistors) and FETs (Field Effect Transistors). BJTs have a physical connection between they current controlling input (base) and the input and output (collector and emitter). This results in a trickle current into the base. FETs have a physical separation between the control (gate) and the input and output (drain and source). BJT and FET transistors are used in virtually every electronic device requiring current regulation or amplification. They make it very easy to precisely control power to a device reliably and with much greater efficiency than other methods. Another common use of transistors is their role in discrete logic. First used in DTL (Diode Transistor Logic) transistors compact nature and high switching speeds lend themselves well to use in logic ICs. In ... ...er clock speed operation than the G4 processor and will include all the latest fabrication developments when released.

Digital Fortress Chapter 39

Room 301. Rocio Eva Granada stood naked in front of the bathroom mirror. This was the moment she'd been dreading all day. The German was on the bed waiting for her. He was the biggest man she'd ever been with. Reluctantly, she took an ice cube from the water bucket and rubbed it across her nipples. They quickly hardened. This was her gift-to make men feel wanted. It's what kept them coming back. She ran her hands across her supple, well-tanned body and hoped it would survive another four or five more years until she had enough to retire. Senor Roldan took most of her pay, but without him she knew she'd be with the rest of the hookers picking up drunks in Triana. These men at least had money. They never beat her, and they were easy to satisfy. She slipped into her lingerie, took a deep breath, and opened the bathroom door. As Rocio stepped into the room, the German's eyes bulged. She was wearing a black negligee. Her chestnut skin radiated in the soft light, and her nipples stood at attention beneath the lacy fabric. â€Å"Komm doch hierher,† he said eagerly, shedding his robe and rolling onto his back. Rocio forced a smile and approached the bed. She gazed down at the enormous German. She chuckled in relief. The organ between his legs was tiny. He grabbed at her and impatiently ripped off her negligee. His fat fingers groped at every inch of her body. She fell on top of him and moaned and writhed in false ecstasy. As he rolled her over and climbed on top of her, she thought she would be crushed. She gasped and choked against his puttylike neck. She prayed he would be quick. â€Å"Si! Si!† she gasped in between thrusts. She dug her fingernails into his backside to encourage him. Random thoughts cascaded through her mind-faces of the countless men she'd satisfied, ceilings she'd stared at for hours in the dark, dreams of having children†¦ Suddenly, without warning, the German's body arched, stiffened, and almost immediately collapsed on top of her. That's all? she thought, surprised and relieved. She tried to slide out from under him. â€Å"Darling,† she whispered huskily. â€Å"Let me get on top.† But the man did not move. She reached up and pushed at his massive shoulders. â€Å"Darling, I†¦ I can't breathe!† She began feeling faint. She felt her ribs cracking. â€Å"?Despiertate!† Her fingers instinctively started pulling at his matted hair. Wake up! It was then that she felt the warm sticky liquid. It was matted in his hair-flowing onto her cheeks, into her mouth. It was salty. She twisted wildly beneath him. Above her, a strange shaft of light illuminated the German's contorted face. The bullet hole in his temple was gushing blood all over her. She tried to scream, but there was no air left in her lungs. He was crushing her. Delirious, she clawed toward the shaft of light coming from the doorway. She saw a hand. A gun with a silencer. A flash of light. And then nothing.

Middle Woodland

The communities in the Middle Woodland Period possess creative beginnings, essential factors of which are native people, a history of domination and existing and widened transferring of the population from various places and societies. This has led in one of the most varied and differentiated communities in the globe, with almost a thousand ethnic societies (Applegate, 2005). Every one of these ethnic communities has its own definitive traits and characteristics and as a consequence of history, territorial variances and inner and outer migration of people, including differences associated to essential elements such as status, sex and territorial setting. The concept of settlement and subsistence based on the Middle Woodland Period includes diversity, involving the emergence of a powerful existence of aborigines and profiles. This illustrates meaningful topics for the Middle Woodland Period communities: the implications of being a member of a community; the interaction between local and individual profiles; establishing and employing in both the connecting and dividing elements in a community with various ethnicities; and the type and scenario of an incoming leadership and governance system (Fortier, 2001). Under the Middle Woodland Period, community is connected to human ecology with regard to the organizations, mechanisms for survival, and the way of thinking of the people, motives and quality of life. It tops the complicated box of concepts which portrays daily happenings in life and attitudes–the comprehensions and assumptions which leads the people’s initiatives and communications with other members of the community. The Swift Creek community existed during the periods of 1-400 CE, while the Santa Rosa society in Western Florida existed during the periods from 150-500 CE. The start of the Middle Woodland indicated a change of settlement to the Interior. As the Middle Woodland era went on, domestic and foreign exchange of exotic products tremendously improved to the point where a trade mechanism became existent on the Chesapeake Bay. Amongst the Southern and northern parts of the Chesapeake Bay, burial areas of significant people were very evident and possessed various presents, most of which were not recognizable to the people (Ritzenthaler, 1991). The most evident archaeological site in the place of burial sites during this period was in the Chesapeake Bay, and is now pertained to as the Hopewell culture. Due to the likeness of works and burial gifts, experts predict a traditional norm of religious beliefs and customs and cultural communication that was present throughout the entire territory (also pertained to as a Hopewell Communication Sphere). However, this could also be seen as the consequence of the fair exchange of goods and/or responsibilities between local families that managed particular regions. Access to food or other basic needs external to a family's region would be done through special agreements with other people. Family leaders would then be laid to rest along with presents obtained from their business partners to represent the interactions they had formed. Under this situation, permanent communities would obviously be established, leading to improved agricultural gains and an increase in the density of people as well (Wittry, 1994). Although majority of the Middle Woodland customs and beliefs are pertained to as â€Å"Hopewellian,† and in spite of the shared ceremonial customs and beliefs, independent beliefs and customs have been established during the Middle Woodland era. These involve the Swift Creek and the Copena beliefs and customs. References Applegate, D, 2005. Woodland Period Systematics in the Middle Ohio Valley.   University Alabama Press Fortier, A, 2001.
