YIELD CURVE: A curve plotting the yields (or returns) on securities with different maturity lengths. The standard yield is for U.S. Treasury securities with lengths ranging from 90 days to 30 years. The five maturity lengths are usually 90 day, 180 day, 2 year, 5 year, 10 year, and 30 year. The shape and slope fo the yield curve indicates the state of the economy and what's likely to come. A normal yield curve has a slight positive slope, with slightly higher yields for longer maturity securities. A steep yield curve suggests the end of a contraction and beginning of an expansion. An inverted, or negatively sloped yield curve is the sign of an upcoming contraction.

Production
- The first unit of this lesson, Short-Run Production, begins our study by introducing a few basic concepts underlying production, especially short run, long run, fixed input, and variable input.
- In the second unit, Production Measures, we take a look the three standard measures of production -- total product, average product, and marginal product.
- The third unit, Product Curves, then presents graphical relations for these three measures -- total product curve, average product curve, and marginal product curve.
- In the fourth unit, Long-Run Production, we examine the role returns to scale play in long-run production.
- The fifth and final unit, Supply, then closes this lesson by previewing the importance of production to the supply decisions by firms.s

SLOPE, AGGREGATE EXPENDITURES LINE The positive slope of the aggregate expenditures line is the sum of the marginal propensity to consume (MPC), marginal propensity to invest (MPI), and marginal propensity for government purchases (MPG), less the marginal propensity to import (MPM). This slope is greater than zero but less than one, reflecting induced expenditures by the four macroeconomic sectors (household, business, government, and foreign). The slope of the aggregate expenditures line determines the magnitude of the multiplier process.
