PERFECT COMPETITION: An ideal market structure characterized by a large number of small firms, identical products sold by all firms, freedom of entry into and exit out of the industry, and perfect knowledge of prices and technology. This is one of four basic market structures. The other three are monopoly, oligopoly, and monopolistic competition. Perfect competition is an idealized market structure that's not observed in the real world. While unrealistic, it does provide an excellent benchmark that can be used to analyze real world market structures. In particular, perfect competition efficiently allocates resources.

The idea of rational ignorance, while popping up on a daily basis for most of us, is quite important come election time. Many voters decided, logically so, that it's not really worth their efforts to get ALL of the details on every candidate and issue on the ballot.

Expenditures made by each of these sectors are commonly termed consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism. In particular, aggregate expenditures are combined with the price level as aggregate demand.
