In other words, any homothetic production function may be obtained by renumbering the isoquants of some production function possessing constant returns to scale. Explain. We completely classify homogeneous production functions with proportional marginal rate of substitution and with constant elasticity of labor and capital, respectively. The aggregate production function is pervasive in macroeconomics. Cobb-Douglas Production Function 5 10 15 20 x1 5 10 15 20 x2 0 10 20 fHx1,x2L FIGURE 3. .

These propagation equations gen-eralize equations (5) and (6) in Proposition 2 and equations (8) and (9) in Proposition 7. We apply our results to estimate generalized homothetic production functions for four industries in the Chinese economy. You should be familiar with the idea of returns to scale. In consumer theory, a consumer's preferences are called homothetic if they can be represented by a utility function which is homogeneous of degree 1.: 146 For example, in an economy with two goods ,, homothetic preferences can be represented by a utility function that has the following property: for every >: (⋅, ⋅) = ⋅ (,)In mathematics, a homothetic function is a monotonic transformation of a function which … The expansion path for a homothetic production function function is a straight line through the origin with a slope greater than one if w > v. is a straight line through the origin with a slope less than one if w < v. is a straight line through the origin though its slope cannot be determined by w and v alone.
