homogeneous function in economics

Now, homogeneous functions are a strict subset of homothetic functions: not all homothetic functions are homogeneous. The Linear Homogeneous Production Function implies that fall the factors of’production are increased in slime proportion. xref Homogeneous Production Function| Economics (1) Q = Kg (L/K) or, (2) Q = Lh (K/L) 0000003970 00000 n function behaves under change of scale. She purchases the bundle of goods that maximizes her utility subject to her budget constraint. A homogeneous function is one that exhibits multiplicative scaling behavior i.e. M(x,y) = 3x2 + xy is a homogeneous function since the sum of the powers of x and y in each term is the same (i.e. the output also increases in the same proportion. Mathematically, we can say that a function in two variables f(x,y) is a homogeneous function of degree nif – f(αx,αy)=αnf(x,y)f(\alpha{x},\alpha{y}) = \alpha^nf(x,y)f(αx,αy)=αnf(x,y) where α is a real number. 0000081008 00000 n 0000042860 00000 n 37 0 obj <> endobj 8.26, the production function is homogeneous if, in addition, we have f(tL, tK) = t n Q where t is any positive real number, and n is the degree of homogeneity. startxref 0000014496 00000 n 0000063993 00000 n The Cobb-Douglas production function is based on the empirical study of the American manufacturing industry made by Paul H.

A consumer's utility function is homogeneous of some degree.

This video shows how to determine whether the production function is homogeneous and, if it is, the degree of homogeneity. 0000019376 00000 n �꫑ This video shows or proves that Cobb-Douglas demand functions are homogeneous to degree zero. 0000004803 00000 n Therefore, not all monotonic transformations preserve the homogeneity property of a utility function. 0000005929 00000 n 0000023663 00000 n 37 69 if all of its arguments are multiplied by a factor, then the value of the function is multiplied by some power of that factor. Homogeneous definition: Homogeneous is used to describe a group or thing which has members or parts that are all... | Meaning, pronunciation, translations and examples For example, in an economy with two goods {\displaystyle x,y}, homothetic preferences can be represented by a utility function {\displaystyle u} that has the following property: for every Homothetic functions are functions whose marginal technical rate of substitution (the slope of the isoquant, a curve drawn through the set of points in say labour-capital space at which the same quantity of output is produced for varying combinations of the inputs) is homogeneous of degree zero. The bundle of goods she purchases when the prices are (p1,..., pn) and her income is y is (x1,..., xn). In thermodynamics all important quantities are either homogeneous of degree 1 (called extensive, like mass, en-ergy and entropy), or homogeneous of degree 0 (called intensive, like density, temperature and speci c heat). 0000040314 00000 n 0000003842 00000 n 0000002974 00000 n 0000004599 00000 n 0000066521 00000 n All economic modeling abstracts from reality by making simplifying but untrue assumptions. One purpose is to support tractable models that isolate and highlight important effects for analysis by suppressing other ef-fects. 0000060303 00000 n trailer Experience in economics and other fields shows that such assump-tions models can serve useful purposes. 0000013757 00000 n Ž¯ºG¤zχ»{:ð\sMÀ!ԟ¸C%“(O}GY. 0000013364 00000 n 0000014918 00000 n �b.����88ZL�he��LNd��ѩ�x�%����B����7�]�Y��k۞��G�2: In economics, the Cobb-Douglas production function Y(K;L) = AK1 L 0000010420 00000 n 0000006505 00000 n 0000028609 00000 n 0000013516 00000 n The function (8.122) is homogeneous of degree n if we have f (tL, tK) = t n f (L, K) = t n Q (8.123) where t is a positive real number.
