BEssay QuestionsIt is argued that small countries tend have more open economies than large ones. Is this empirically verified? What are the logical underpinnings of this argument?Answer: Yes. They do not have sufficient resources to satisfy consumption needs; and also do not have a sufficiently large market to enable their industries to avail themselves of scaleeconomy possibilities.Another answer would rely on a location argument. Assume that the “natural” marketfor any given plant is a circle with a radius of n miles with the plant at its center.Assuming that the production plants are located randomly throughout the country, thenthe probability that the typical circular market will encompass some foreign country isgreater the smaller is the country.It is argued that if a rich high wage country such as the United States were to expand trade with a relatively poor and low wage country such as Mexico, then U.S. industry would migrate south, and U.S. wages would fall to the level of Mexico’s. W hat do you think about this argument?Answer: The student may think anything. The purpose of the question is to set up adiscussion, which will lead to the models in the following chapters.Some patterns of international trade are easier to explain than others. Give several examples and explain.Answer: Historical circumstance can explain some patterns such as the relatively largetrade flows from West Africa to France. The relatively sparse trade between countries withinSouth America seems curious.International trade tends to prove that international trade is beneficial to all trading countries. However, casual observation notes that official obstruction of international trade flows is widespread. How might you reconcile these two facts?Answer: Like question 2, this is meant to allow students to offer preliminary discussions of issues, which will be explored in depth later in the book.It is argued that small countries tend have more open economies than large ones.

It is also an area for which data was relatively widely available very early on. Why do you suppose this is the case?Answer: In ancient times, public finance was not well developed. Most of the populationwas not producing and consuming within well-developed market economies, so that income and sales taxes were not efficient. One of the most convenient ways for governments to obtainresources was to set up custom posts at borders and tax. Hence international trade was of greatpolicy interest to princes and kings, as was precise data of their main tax base.Quantitative/Graphing ProblemsThe figure above is the Production Possibility Frontier (PPF) of Baccalia, where only two products are produced, clothing and wine. In fact Baccalia is producing on its PPF at point A. By and large the people of Baccalia are content, as both their external and internal needs for warmth are satisfied in the most economically efficient manner possible, given their available productive resources (and known technology). How much wine is being produced? How much cloth? If a person in this country wanted to purchase a liter of wine, what would be the price he or she would have to pay?Judging from what you learned in the previous paragraph, can you indicate at which point (if atall) the Community Indifference Curve is tangent to the Production Possibility Frontier? Explain your reasoning.Answer: 6 million liters of wine are being produced.3 million square yards of cloth are being produced.The price of 1 liter of wine is one half of a square yard of cloth.The tangency is at point A. We know this because otherwise the country would not beproducing at the point of maximum economic efficiency.One day, Baccalia joined the WTO and joined the Global Village. They discovered that in the LWE (London Wine Exchange), 1 liter of wine is worth 1 square yard of cloth. What is the logical production point they should strive for?Answer: 10 million liters of wine.They wish to enjoy to the fullest from the gains from trade, but are not willing to give up imbibing even one drop of wine from the 6 million liters they consumed in their original autarkic state. If their new consumption point is a point we shall designate as point b, describe where this point would be found.Answer: Vertically above point aWhere is the Community Indifference Curve family of curves tangent to their new Consumption Possibility Frontier?Answer: At point b.How can you prove that Baccalia has in fact gained from the availability of trade, and that their new situation is superior to the pre-trade situation (with which they were quite content)?Answer: The country was consuming at point a before trade. It is now consuming at point b with trade. Point b represents a superior welfare combination of goods as compared to point a,since at b the country has more of each of the goods.。
