ACCELERATOR: The ratio between investment expenditures and the change in gross domestic product. This is based on the notion that business investment depends on the rate of growth of aggregate output. If the economy is expanding, in other words, then the business sector invests in more capital goods to produce the extra output needed. This accelerator effect modifies and magnifies the simply multiplier effect based on the induced consumption and the marginal propensity to consume.

FOUR-SECTOR KEYNESIAN MODEL

A Keynesian model of the macroeconomy that includes all four macroeconomic sectors, the household sector, the business sector, the government sector, and the foreign sector. This Keynesian model variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model. This model provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the C + I + G + (X - M) line and the 45-degree line. Two related variations are the two-sector Keynesian model and the three-sector Keynesian model.
