International Economics, 17e (Pugel) Chapter 4 Trade: Factor Availability and Factor Proportions Are Key 1) In international trade jargon, constant-cost production-possibility curves are associated with ________ specialization, while increasing-cost production-possibility curves are associated with ________ specialization. A) no; partial B) complete; no C) complete; partial D) partial; complete 2) Which of the following statements is true about production-possibility curves? A) Constant-cost production-possibility curves are straight lines and usually lead to complete specialization under free trade. B) Under free trade, bowed-out production-possibility curves are associated with partial specialization, because the opportunity cost of producing each good is constant along the curve. C) Increasing-cost production-possibility curves provide us with information about consumer preferences. D) Constant-cost production-possibility curves are convex to the origin. 3) Which of the following best explains why increasing marginal costs of production arise? A) The factor endowments vary across countries. B) All the factor inputs are not fully utilized in the production of different commodities. C) Different consumers have different tastes and preference sets. D) Different commodities use inputs in different proportions. 4) Assume that Country X produces two goods—sugar and shoes—and that the countrys production possibility curve is bowed-out. As the country produces more sugar the opportunity cost of sugar in terms of shoes foregone will A) increase. B) decrease. C) initially increase and then decrease. D) remain unchanged. 5) Consider a two-country, two-commodity model. Each country has an increasing-cost production-possibility curve. In this model the amounts of the goods that are produced in a country in the n
