ECO 204 Week 1

1. Elasticity of Demand Taxicab fares in most cities are regulated. Several years ago taxicab drivers in Boston obtained permission to raise their fares 10 percent, and they anticipated that revenues would increase by about 10 percent as a result. However, when the commissioner granted the 10 percent increase, revenues increased by only about 5 percent. What can you infer about the elasticity of demand for taxicab rides? What were taxicab drivers assuming about the elasticity of demand? Respond to at least two of your fellow students’ postings.

2. Marginal Utility Suppose that you observe that total utility rises as more of an item is consumed. What can you say for certain about marginal utility? Can you say for sure that it is rising or falling or that it is positive or negative? When does the law of diminishing marginal utility set in and what does this illustrate about where you should stop consuming if you were eating at an all you can eat buffet? Respond to at least two of your fellow students’ postings.
