CHAPTER 8

1)Holding other factors constant, bad weather causes the supply curve for agricultural products to

1. Shift to the left, causing the prices of agricultural products to rise
2. Shift to the left, causing the prices of agricultural products to fall
3. Stay the same
4. The supply curve does not shift. Only the demand curve shifts.

2. Movie theatres decided to increase the price of movie tickets. Holding other factors constant, what happens to the demand for popcorn in the movie theatres?
   1. Demand for popcorn shifts to the left because popcorn and movies are substitute goods.

3. All these factors will shift good X’s supply curve, except
   1. Bad weather
   2. Change in the price of X

4. Changes in prices of a good causes
   1. Movement along the demand curve
   2. Movement along the supply curve
   3. No effect to either curve
   4. Both a and b

5. Suppose recent and widely circulated medical article reports new benefits of cycling exercise. Simultaneously, the price of the parts needed to make bikes falls.

9. What will happen to the demand for beers such as Natural Light, Coors Light and Bud Light near college towns if students’ income increased tremendously?
   1. Demand will fall because students love these beers

   3. Demand will rise because these beers are considered inferior goods
   4. Demand will not change as students are already maximizing their drinking capacity

10. Holding other factors constant, a decrease in the tax for producing cars causes

1. The supply curve to shift to the left, causing the prices of coffee to rise
