REALISM OF PERFECT COMPETITION: 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 a one or two of the four key characteristics of perfect competition, none matches all four sufficiently that we can declare a perfectly competitively industry. 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.

INTERCEPT, AGGREGATE EXPENDITURES LINE The intercept of the aggregate expenditures line indicates autonomous expenditures, aggregate expenditures that do not depend on the level of income or production. This can be thought of as aggregate expenditures that the four macroeconomic sectors (household, business, government, and foreign) undertake regardless of the state of the economy. Autonomous expenditures are affected by the aggregate expenditures determinants, which cause a change in the intercept and a shift of the aggregate expenditures line.

Collecting WELFAREI know word travels quickly among pedestrians of Shady Valley, but perhaps you haven't heard the latest. Pollyana Pumpernickel, the proprietor of Pollyana's Pet Palace, is no longer a pet proprietor. She's fallen on hard times, and fallen quite hard. Her husband of twelve years, Paul Pumpernickel has dumped her and their three young children to pursue insurance alternatives with Tricia Comer -- Smilin' Ted's sister and business partner in the All Comers Insurance Agency. Pollyana is distraught, to say the least. Paul Pumpernickel had been the dutiful househusband and caring father in his marriage partnership with Pollyana, but those duties fell onto the heavily burdened shoulders of Pollyana. The burden was too much. Pollyana's Pet Palace plundered into oblivion, leaving Pollyana penniless and jobless. Her only alternative was our government's public assistance program -- what you and I know as welfare. She's not pleased with her current social status, and neither, apparently is Winston Smythe Kennsington III, who ridicules poor Pollyana at every opportunity.
