ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.

Rather than a mere recessionary pothole, these are best thought of as depressionary canyons. The Great Depression of the 1930s was the most memorable depressionary canyon on record for the good old U. S. of A. The question we need to ponder over the next few pages is: Are there any more depressionary canyons like the 1930s lurking along the economic pavement?
