KEY TAKEAWAY The immobile factor model is a two-country, two-good, two-factor, perfectly competitive general equilibrium model that is identical to the Ricardian model except that labor cannot move across industries. EXERCISE 1. Jeopardy Questions. As in the popular television game show, you are given an answer to a question and you must respond with the question. For example, if the answer is “a tax on imports,” then the correct question is “What is a tariff?” 1. The assumption that distinguishes the immobile factor model from the Ricardian model. 2. The term describing the period of time encompassed by the immobile factor model. 3. The firms’ objective in the immobile factor model. 4. The consumers’ objective in the immobile factor model. 5. The term for the entire collection of assumptions made in the immobile factor model. [1] Note that this assumption is a technical detail that affects how the trading equilibrium is depicted but is not very important in understanding the main results.

4.5 The Production Possibility Frontier in the Immobile Factor Model LEARNING OBJECTIVE 1. Learn how the immobile factor model’s production possibility frontier (PPF) is drawn and how it compares with the Ricardian model’s PPF. To derive the production possibility frontier (PPF) in the immobile factor model, it is useful to begin with a PPF from the Ricardian model. In the Ricardian model, the PPF is drawn as a straight line with endpoints given by L/aLC and L/aLW, where L is the total labor endowment available for use in the two industries (see Figure 4.1 "The Immobile Factor Model PPF"). Since labor is moveable across industries, any point along the PPF is a feasible production point that maintains full employment of labor. Figure 4.1 The Immobile Factor Model PPF Next, let’s suppose that some fraction of the L workers are cheesemakers, while the remainder are winemakers. Let LØØC be the number of cheesemakers and LØØW be the number of winemakers such that LØØC+LØØW=L. If we assume that these workers cannot be moved to the other industry, then we are in the context of the immobile factor model. In the immobile factor model, the PPF reduces to a single point represented by the blue dot in Figure 4.1 "The Immobile Factor Model PPF". This is the only production point that generates full employment of both Saylor URL: http://www.saylor.org/books Saylor.org 158
