13. Supply and Demand
Consider the following events: Researchers shows that eating lobsters increases the risk of heart attack, and at the same time, there is a new
regulation that limit the number of lobsters people can fish.

7. Determinants of supply
The following calculator shows the supply curve for sedans in an imaginary market. For simplicity, assume that all sedans are identical and sell for the
same price. Two factors that affect the supply of sedans are the level of technical knowledge in this case, the speed with which manufacturing robots
can fasten bolts, or robot speed-and the wage rate that auto manufacturers must pay their employees. Initially, the graph shows the supply curve
when robots can fasten 2,500 bolts per hour and autoworkers earn $25 per hour.
Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph.
Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.

- 16. Determinants of supply The following graph shows the supply curve for sedans in an imaginary market. Assume that all sedans are identical and sell for the same price. Two factors that affect the supply of sedans are the technology-the speed with which auto-manufacturing robots can fasten bolts, or "robot speed"-and the wage rate that auto manufacturers pay their employees. Initially, the graph shows the supply curve when robots can fasten 1,000 bolts per hour and autoworkers earn $35 per hour. Use the graph input tool to help you answer the following questions.

Another supply and demand puzzle The market price of cheeseburgers in a college town increased recently, and the students in an economics class are debating the cause of the price increase. Some students suggest that the price increased because several burger joints in the area have recently gone out of business. Other students attribute the increase in the price of cheeseburgers to a recent increase in the price of calzones at local pizza parlors. Everyone agrees that the increase in the price of calzones was caused by a recent increase in the price of pizza dough, which is not generally used in making cheeseburgers. Assume that burger joints and pizza parlors are entirely separate entities-that is, there aren't places that serve both cheeseburgers and calzones. The first group of students thinks the increase in the price of cheeseburgers is due to the fact that several burger joints in the area have recently gone out of business.
