Document Summary

You want to tax inelastic goods to minimize dead weight loss. If domestic price is greater than the world price you import it (sugar). In this scenario, buyers are better off but sellers are hurt because prices will go down. If the domestic price is less than the world price you export it (technology). In this scenario sellers are better off but consumers are hurt because prices will increase. Free trade creates new wealth which makes people better off. Whoever has the higher surplus is the winner of the transaction. Tariffs are per-unit taxes on imports and exports that raise the world price. They serve two purposes, to increase revenue and protect resources. Export tariffs benefit consumers but hurt domestic firms (rare) Import tariffs benefit domestic firms but hurt consumers. Consumer surplus= pre-trade: a, post-trade: a+b+c+d+e+f+g, post-trade + tariff: a+b+c. Producer surplus= pre-trade: b+d+h, post-trade: h, post-trade + tariff: d+h. Dwl= pre-trade: c+e+f+g, post-trade: none, post-trade + tariff: e+g.

1. If we know that Canada exports maple syrup, we can conclude that maple syrup consumers in Canada are worse off than they would be in the absence of trade.

Is the statement true or false?

2. When a country opens up to trade in a good for which it has a comparative advantage, and the country begins to export the good, we can conclude that:

	a.	The domestic price will fall after trade opens up.
	b.	The total surplus for this good will increase as a result of opening up the market to international trade.
	c.	Opening the market to international trade will create a deadweight loss.
	d.	Both buyers and sellers in that country will be better off as a consequence of opening up the market to international trade.

Professional baseball teams earn substantial revenues through ticket sales. To maximize profit, they offer significantly lower ticket prices for children (whose demand is elastic) than for adults (whose demand is inelastic). This discount may be as much as 50 percent.

If this type of price discrimination increases revenue and profit, why don't teams also price discriminate at the concession stands? Why don't they offer half-price hot dogs, soft drinks, peanuts, and Cracker Jack to children?

The answer involves the three requirements for successful price discrimination. All three requirements are met for game tickets: (1) The team has monopoly power; (2) it can segregate ticket buyers by age group, each group having a different elasticity of demand; and (3) children cannot resell their discounted tickets to adults.

It's a different situation at the concession stands. Specifically, the third condition is not met. If the team had dual prices, it could not prevent the exchange or resale of the concession goods from children to adults. Many adults would send children to buy food and soft drinks for them: Here's some money, Billy. Go buy six hot dogs. In this case, price discrimination would reduce, not increase, team profit. Thus, children and adults are charged the same high prices at the concession stands. (These prices are high relative to those for the same goods at the local convenience store because the stadium sellers have a captive audience and thus considerable monopoly power.)

Finally, price discrimination often occurs in international trade. A Russian aluminum producer, for example, might sell aluminum for less in the United States than in Russia. In the United States, this seller faces an elastic demand because several substitute suppliers are available. But in Russia, where the manufacturer dominates the market and trade barriers impede imports, consumers have fewer choices and thus demand is less elastic.

First, give your own thoughts on the above analysis of the concept of Price Discrimination. Second, give some concrete examples from your own life where you have been confronted by situations of Price Discrimination. Finally are there some forms of Price Discrimination that should be illegal?
