Heckscher-Ohlin Model

1. Suppose that a free-trade equilibrium exists in a two-country, two-good, two-factor world. Assume that the two goods, chemicals (C) and electronic appliances (E), both employ capital (K) and labor (L), and that both factors are perfectly mobile across sectors. Also assume that:

• Germany is relatively capital-abundant
• China is relatively labor-abundant.
• Chemicals are relatively capital-intensive.
• Electronic appliances are relatively labor-intensive.
• Assume that tastes and technologies are identical in the two countries.

(a) On the graph below, sketch the relationship between relative product price, relative factor price and relative factor use in each industry in Germany and China. (Under the assumption of identical technologies, the same curves can be used to describe the relationships in both Germany and China.)

(b) On the graph below, sketch & label the relative supply curves of the two countries.

• Briefly explain why they differ:

• Then, sketch & label the world relative supply curve.

(c) Using the graph in part (a), label the relative price of electronics, the relative wage (w/r), and each industry's relative employment of labor-to- capital in each country prior to trade (i.e. in autarky). Then make the following comparisons (write >, <, or =):

(d) Before trading, is the real wage higher in GR or China? Briefly explain why.

(e) Now suppose that GR and China trade freely. Which good will China export to GR?

(f) Describe the effect of free trade on:

(g) Of the four groups below, who are the "winners" and who are the "losers" from the freeing of trade between GR and China?

• Capital owners in GR: winners/losers
• Capital owners in China: winners/losers
• Workers in GR: winners/losers
• Workers in China: winners/losers

(h) Suppose the PPF for GR is given by the graph below. Using this graph, demonstrate that in theory, all individuals in GR could be made better off by trading freely with China.

• Briefly describe what sort of policy would be necessary in practice to make every individual better off.

(i) TRUE/ FALSE (Explain your answer briefly): Under free trade, an expansion of China's capital endowment leads to a reduction in GR's overall welfare.

(j) TRUE/ FALSE (Explain your answer briefly): After China's capital endowment increases, GR would now be better off if it did not trade with China.

2. The graph below shows the production possibilities frontier of a country that produces two goods: semi-conductors (S) (skill-intensive) and furniture (F) (unskilled labor-intensive). Assume that this country engages in free trade, and that it has a relatively high ratio of skilled labor to unskilled labor compared to the rest of the world (i.e. this country is skill-abundant).

(a) Which good will this country export to the rest of the world?

Consider the effect of an increase in the population of unskilled labor in this country. In particular:

(b) Using the graph on the left, show the effect on the country's production possibilities frontier (sketch the new PPF).

(d) What happens to the country's terms of trade and to its overall welfare?

3. TRUE/ FALSE (Explain your answer briefly): In the Heckscher-Ohlin Model with two countries and two goods, a country that produces both goods in the free trade equilibrium neither gains nor loses from trade.

4. TRUE/ FALSE (Explain your answer briefly): The predictions of the Heckscher- Ohlin Model are consistent with the fact that wage inequality, as measured by the ratio of skilled to unskilled wages, increased in both the US (a skill-abundant country) and in Mexico (abundant in unskilled labor) as trade between the US and Mexico was liberalized.
