LERNER INDEX: The difference between price (p) and marginal cost (mc) as a fraction of price, that is [p-mc]/p. The Lerner index is usually taken as an indicator of market power because the larger the index, the larger the difference between price and marginal cost, that is, the larger the distance between the price and the competitive price. The Lerner index depends on the elasticity of demand. The Lerner index is also called the price-cost margin.

GAINS FROM TRADE

The combination of consumer surplus and producer surplus obtained by buyers and sellers when engaging in a market exchange. Gains from trade arise because buyers are typically willing and able to pay a higher price to purchase a good than what they end up paying and because sellers are typically willing and able to accept a lower price to sell a good than what they end up receiving. Both sides of the market exchange are thus better off, have a net gain in welfare, by making the trade. While all types of market exchanges generate gains from trade, this topic is perhaps most important for an understanding of international trade.

This isn't me! What am I?

Only 1% of the U.S. population paid income taxes when the income tax was established in 1914.
"You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you're doing, you'll stop at the first giant hurdle. "

-- George Lucas
