-
The price of milk in a country increases from €1.00 per liter to €1.70 per liter, and the quantity supplied does not change. This suggests the short-run supply of milk in this country is closest to being:
- A.perfectly elastic, meaning elasticity of supply is infinite
- B.perfectly inelastic, meaning elasticity of supply is zero
- C.perfectly inelastic, meaning elasticity of supply is infinite

A researcher has determined that a firm's supply function for a good is Qs = -60 + 30P +2.2Psub, where P is the price of the good and Psub is the price of a substitute good. If there are 8 identical suppliers in the market, and the price of the substitute good is 15, the market supply curve is given by:
- A.P-0.04Q + 0.75.
- B.P = 0.0042Q + 0.9.
- C.P = 0.18Q + 1.32.
-

- A.positive, and for substitutes the cross elasticity of demand is negative
- B.negative, and for substitutes the cross elasticity of demand is negative
- C.negative, and for substitutes the cross elasticity of demand is positive
-
Compared to a competitive market result, a single-price monopolist will most likely:
- A.adopt a marginal cost pricing strategy, which will decrease consumer surplus.
- B.increase price, decrease consumer surplus, and increase producer surplus.
- C.reduce output, create a deadweight loss, and decrease both producer and consumer surplus.
