of comparative advantage provide a good explanation of current patterns of international trade? For the last two centuries the international trade evolved a lot and many economists tried to explain it. One of the first theories that attempted to explain the international trade pattern was the Absolute advantage theory. A.Smith was a great economist; he is the one who created this theory. For A. Smith countries should specialize in products in which they have an absolute advantage. It was a good

THEORY OF ABSOLUTE ADVANTAGE “If a foreign country can supply us with a commodity cheaper than we ourselves can make it‚ [we had] better buy it of them with some part of our own industry‚ employed in a way in which we have some advantage.” -Adam Smith (WN‚ IV.ii.12) This means that a nation produces and exports those commodities which it can produce more cheaply than other nations‚ and imports those which it cannot. A nation will not produce a good that is produced more expensively at

Absolute Advantage Absolute advantage is a situation where a country can produce a product more efficient than any country in producing it. It also refer to ability to produce a particular good at a lower absolute cost than another. That’s mean a country that have an absolute advantage is a country that can produce a product that are due to some combination. The determinant of absolute advantage for a country is such as favorable climate‚ good soils‚and accumulated expertise. For example‚ Bangladesh

with less developed countries where these goods are produced for a higher price. This is striking but this comes out from the theory of “relative advantage”. The absolute advantage is the fact that one country (named A) is more efficient and productive than another country (named B) in the production of all goods. It is said that A has an absolute advantage on B. When these two countries have different relative efficiencies‚ they can make profit from trading with each other. For instance‚ if B can

He exerts a 650.0 N force parallel to the ramp. What is the mechanical advantage of the ramp? What is the efficiency of the ramp? Your response should include all of your work and a free-body diagram. Answer: 650 N is mvoed through a distance of 5m. The result is 100*9.8 N is moved up thrugh a distance of 3m. Mechnical

the home advantage. Simply put‚ home advantage means the persistence of home teams winning a majority of games. This phenomenon has been around as long as team competition has been in existence but did not receive scientific study until 1977. Schwartz and Barsky (1977) did the first psychological study of home advantage. Given that this phenomenon indeed exists‚ Schwartz and Barsky intended to find why it exists. Before this study‚ hypotheses abounded as to the cause of home advantage (travel
