WIDGET: A fictitious good commonly used by economic instructors to demonstrate economic principles or undertake hypothetical analyses. For example, the analysis of short-run production for a firm might be demonstrated through the production of widgets. Alternatively, the law of demand might be illustrated with a table or curve comparing the price of widgets with the quantity demanded of widgets. If such a good exists, and there is no clear evidence that widgets have every existed, it is a small mechanical device, constructed of interlocking cogs, several knobs, and at least one handle. Widgets are most often used when thingamajigs and dohickies are unavailable.

KEYNESIAN ECONOMICS: A school of thought developed by John Maynard Keynes built on the proposition that aggregate demand is the primary source of business cycle instability, especially recessions. The basic structure of Keynesian economics was initially presented in Keynes' book The General Theory of Employment, Interest, and Money, published in 1936. For the next forty years, the Keynesian school dominated the economics discipline and reached a pinnacle as a guide for federal government policy in the 1960s. It fell out of favor in the 1970s and 1980s, as monetarism, neoclassical economics, supply-side economics, and rational expectations became more widely accepted, but it still has a strong following in the academic and policy-making arenas.

PERFECTLY ELASTIC An elasticity alternative in which infinitesimally small changes in one variable (usually price) cause infinitely large changes in another variable (usually quantity). Quantity is infinitely responsive to price. Any change in price, no matter how small, triggers an infinite change in quantity. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Perfectly elastic is one of five elasticity alternatives. The other four are perfectly inelastic, relatively elastic, relatively inelastic, and unit elastic.
