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.

POLICY LAGS Time lags that occur between the onset of an economic problem and the full impact of the policy intended to correct the problem. Policy lags come in two broad categories--inside lag (getting the policy activated) and outside lag (the subsequent impact of the policy). The three specific inside lags are recognition lag, decision lag, and implementation lag. The one specific outside lag is termed impact lag. Policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy. Policy lags, especially inside lags, are often different for monetary policy than for fiscal policy.
