30、 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 a

Assume that the “natural” market for 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, th

The purpose of the question is to set up a discussion, which will lead to the models in the following chapters.Some patterns of international trade are e

34、asier to explain than others. Give several examples and explain.Answer:Historical circumstance can explain some patterns such as the relatively large trade flows from West Africa to France. The relatively sparse trade between countries withinSouth America seems curious.International trade tends to p

How might you reconcile these two facts?Answer:Like question 2, this is meant to allow students to offer preliminary discussio

However, casual observation notes that official obstruction of international trade flows is widespread. How might you reconcile these two facts

42、?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.International Trade theory is one of the oldest areas of applied economic policy analysis. It is also an area for which data was relatively widely av

43、ailable very early on. Why do you suppose this is the case?Answer:In ancient times, public finance was not well developed. Most of the population was not producing and consuming within well-developed market economies, so that income and sales taxes were not efficient. One of the most convenient ways

44、 for governments to obtain resources was to set up custom posts at borders and tax. Hence international trade was of great policy interest to princes and kings, as was precise data of their main tax base.nQuantitative/Graphing ProblemsThe figure above is the Production Possibility Frontier (PPF) of

45、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

46、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 whi

47、ch point (if at all) 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 be producing 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),
