- Suppose a drug company cannot prevent resale between rich and poor countries and increases output from 3 million (serving only the rich country with a price of $80 per treatment) to 9 million (serving both the rich and the poor countries with a price of $30 per treatment). Marginal cost is constant and equal to $10 per treatment in both countries.

- 3. Production Costs Clean 'n' Shine is a competitor to Spotless Car Wash. Like Spotless, it must pay $150 per day for each automated line it uses. But Clean 'n' Shine has been able to tap into a lower-cost pool of labor, paying its workers only $100 per day. Clean 'n' Shine's production technology is given in the following table. To determine its short-run cost structure, fill in the blanks in the table. Fill in the columns below.

Elasticity and the Minimum Wage - The following graph depicts two labor markets for cashiers. We assume the same supply curve (cashiers respond similarly to wage offers in each city) but different demand functions (employer demand is more elastic – more responsive to wages - in one city than the other, perhaps because one has higher quality retail stores than the other). The y-axis shows hourly wages in dollars; the x-axis shows the number of employees in hundreds.
