AE LINE: Another term for aggregate expenditure line, which is a line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

FACTOR DEMAND ELASTICITY The elasticity of a factor demand curve is affected by four items: (1) the price elasticity of demand for the good produced, (2) the production function technology and elasticity of marginal physical product, (3) the ease of factor substitutability, and (4) the share of the factor's cost relative to total cost. Changes in any of these four items cause the price elasticity of factor demand to change. In other words, the quantity of factor services demanded becomes more or less sensitive to changes in the factor price.
