SLOPE, LONG-RUN AGGREGATE SUPPLY CURVE: The long-run aggregate supply (LRAS) curve is a vertical line with an infinite slope, reflecting the independent relation between the price level and aggregate real production. A higher price level is associated with the same real production as a lower price level. And this real production is that produced when resources are fully employed, that is, full-employment production. Real production is unaffected by the price level because prices are flexible in the long run. Long-run price flexibility ensures that ALL markets (product, financial, and resource) are in equilibrium.

Factor Demand
- The first unit of this lesson, Background, begins this lesson by laying the foundations for the study of factor demand.
- In the second unit, Derived Demand, we see how the demand for a factor of production is based on the demand for the good it produces.
- The third unit, The Curve, then derives the factor demand curve, which is the relation between the price employers are willing to pay and the quantity demanded.
- In the fourth unit, Determinants, we examine the three key determinants that shift the factor demand curve -- product price, factor productivity, and other factor prices.
- The fifth and final unit, Taking Stock, then closes this lesson with a review of factor demand and a preview of factor market analysis in other lessons.

AGGREGATE DEMAND The total real expenditures on final goods and services produced in the domestic economy that buyers are willing and able to undertake at different price levels, during a given time period (usually a year). Aggregate demand, usually abbreviated AD, is an inverse relation between price level and aggregate expenditures. This is one half of the AS-AD (aggregate market) analysis. The other half is aggregate supply. Aggregate demand consists of four aggregate expenditures--consumption expenditures, investment expenditures, government purchases, and net exports--made by the four macroeconomic sectors--household, business, government, and foreign.

Today, you are likely to spend a great deal of time browsing about a thrift store wanting to buy either a box of multi-colored, plastic paper clips or several orange mixing bowls. Be on the lookout for telephone calls from former employers.
