DEADWEIGHT LOSS: A net loss in social welfare that results because the benefit generated by an action differs from the foregone opportunity cost. This is usually the combination of lost consumer surplus and lost producer surplus, and indicates of the inefficiency of a situation. Deadweight loss is commonly illustrated by a market diagram if the quantity of output produced results in a demand price that exceeds the supply price. The triangle formed by the demand curve above, supply curve below, and quantity to the left is the area of deadweight loss. If demand price equals supply price, this triangle disappears and so too does the deadweight loss. Deadweight loss can result from government actions (taxes, price controls) or from market failures (externalities, market control)

J CURVE: An interesting relationship that exists between the exchange rate for a nation's currency and its balance of trade. In principle, the drop in a nation's exchange rate, or price of currency, makes the currency less expensive to "buy." With "cheaper" currency the price of domestic production is less and the price of foreign stuff is more, causing an increase in exports to other countries and drop in imports coming in from foreign producers. The economy thus moves in the direction away from a trade deficit and toward a trade surplus. However, the first few months after a drop in the exchange rate the balance of trade goes in the other direction, with any existing trade deficit increasing or any trade surplus shrinking. This occurs because the quantities imported and exported don't change in the short run, but the prices do. Because more is paid for the same amount of imported goods and receive less for the same amount of exports, total spending on imports increases, total revenue received from exports declines, and the movement is in the trade deficit direction. Once those quantities start adjusting in the long run, then we see a movement in the direction of a trade surplus.

PERFECT COMPETITION, REALISM Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to one or two of the four key characteristics of perfect competition, none matches all four sufficiently that they can be declared PERFECTLY competitively. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.
