A first order Differential Equation is homogeneous when it can be in this form: In other words, when it can be like this: M(x,y) dx + N(x,y) dy = 0. These items might vary in physical appearance, as well as quality and price. This paper presents the identification of heterogeneous elasticities in the Cobb-Douglas production function.

N #1��~n�]V6b��, In mathematics, a homogeneous function is one with multiplicative scaling behaviour: if all its arguments are multiplied by a factor, then its value is multiplied by some power of this factor.. For example, a homogeneous real-valued function of two variables x and y is a real-valued function that satisfies the condition (,) = (,) for some constant k and all real numbers α.

An example of a heterogeneous product is the car. endstream Using the province-level data in China, this paper shows that capital shares have a very significant and positive effect on per capita GDP. Abstract: This paper presents the identification of heterogeneous elasticities in the Cobb-Douglas production function. Applying our approach to plant-level data from Colombia and Chile, we find that a gross output production function implies fundamentally different patterns of productivity heterogeneity than a value-added specification.
