Aggregate Demand
This lesson introduces aggregate demand, the demand-side of the aggregate market. The aggregate market is the key model used to explain and analyze the workings of the macroeconomy and aggregate demand is a critical half of this model (the other is aggregate supply). Taking a clue from market demand, this lesson examines the nature of aggregate demand, including the relation between the price level and aggregate expenditures, the reason the aggregate demand curve is negatively sloped, and the assorted aggregate demand determinants that cause the aggregate demand curve to shift. - The first unit of this lesson introduces the concept of aggregate demand and how it fits into the study of macroeconomics in terms of the aggregate market and circular flow.
- In the second unit, we example the four aggregate expenditures -- consumption, investment, government purchases, and net exports -- the make up aggregate demand.
- The third unit then examines the aggregate demand curve that captures the aggregate demand relation between the price level and aggregate expenditures, especially the importance of the real-balance, interest-rate, and net-export effects.
- A look at the assorted aggregate demand determinants that shift the aggregate demand curves is the topic of the fourth lesson.
- We end this lesson in the fifth unit with a look how demand-management policies work to stabilize business cycles through aggregate demand.

ADVERSE SELECTION An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.
