Use a game tree to illustrate why an aircraft manufacturer may price below the current marginal cost in the short run if it has a steep learning curve.
(Hint:
Show that learning by doing lowers its cost in the second period.)
Part 2

- As indicated in the attached image, U.S. earnings for high- and low-skill workers as measured by educational attainment began diverging in the 1980s. The remaining questions in this problem set use the model for the labor market developed in class to walk through potential explanations for this trend. 1. Assume that there are just two types of workers, low- and high-skill. As a result, there are two labor markets: supply and demand for low-skill workers and supply and demand for high-skill workers. Using two carefully drawn labor-market figures, show that an increase in the demand for high skill workers can explain an increase in the relative wage of high-skill workers. 2. Using the same assumptions as in the previous question, use two carefully drawn labor-market figures to show that an increase in the supply of low-skill workers can explain an increase in the relative wage of high-skill workers.arrow_forwardPublished in 1980, the book Free to Choose discusses how economists Milton Friedman and Rose Friedman proposed a one-sided view of the benefits of a voucher system.
