HOMOGENEOUS OF DEGREE N: A property of an equation the exists if independent variables are increased by a constant value, then the dependent variable is increased by the value raised to the power of n. The value of n can be greater than, less than, or equal to one. This property often surfaces in the analysis of production functions. If n = 1, then a doubling independent variables results in a doubling of the dependent variable and the production function has constant returns to scale. If n > 1, then a doubling independent variables results in more than a doubling of the dependent variable and the production function has increasing returns to scale. If n < 1, then a doubling independent variables results in less than a doubling of the dependent variable and the production function has decreasing returns to scale.

INFLEXIBLE PRICES The proposition that some prices adjust slowly in response to market shortages or surpluses. This condition is most important for macroeconomic activity in the short run and short-run aggregate market analysis. In particular, inflexible prices (also termed rigid prices or sticky prices) are a key reason underlying the positive slope of the short-run aggregate supply curve. Prices tend to be the most inflexible in resource markets, especially labor markets, and the least inflexible in financial markets, with product markets falling between the two.
