AGGREGATE EXPENDITURES: The total expenditures on gross domestic product undertaken in a given time period by the four sectors -- household, business, government, and foreign. Expenditures made by each of these sectors are specifically labeled 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.

|
Page: 10 of 20

While the market supply curve and the short-run aggregate supply curve look similar, there are important differences.- The price and quantity for the short-run aggregate supply curve are the price level and real production, not the price and quantity of a specific good.
- The positive slope of the short-run aggregate supply curve is based on rigid wages, tapping into frictional, and structural unemployment, and misperceptions about real wages. The slope of the market supply curve is based on increasing opportunity cost.
- The short-run aggregate supply curve is not just the aggregation of all market supply curves in the economy.

"You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you're doing, you'll stop at the first giant hurdle. " -- George Lucas
