# homogeneous production function

Constant Elasticity of Substitution Production Function, SEBI Guidelines on Employee Stock Option Scheme, Multiplier-Accelerator Interaction Theory. Consequently, the cost minimising capital-labour ratio will remain constant. (iii) Finally, if α + β < 1, there are decreasing returns to scale. Thus, with the increase in labor and capital by “n” times the output also increases in the same proportion. A production function which is homogeneous of degree 1 displays constant returns to scale since a doubling all inputs will lead to an exact doubling of output. Share Your PDF File If n=1 the production function is said to be homogeneous of degree one or linearly homogeneous (this does not mean that the equation is linear). A function is said to be homogeneous of degree n if the multiplication of all of the independent variables by the same constant, say λ, results in the multiplication of the independent variable by λn. These functions are also called ‘linearly’ homogeneous production functions. A production function which is homogeneous of degree 1 displays constant returns to scale since a doubling all inputs will lead to an exact doubling of output. Finally it is shown that we cannot dispense with these assumptions. Welcome to EconomicsDiscussion.net! If a production function is homogeneous of degree one, it is sometimes called "linearly homogeneous". Homogeneous functions arise in both consumer’s and producer’s optimization prob- lems. x2 is x to power 2 and xy = x1y1 giving total power of 1+1 = 2). The concept of linear homogeneous production function can be further comprehended through the illustration given below: In the case of a linear homogeneous production function, the expansion is always a straight line through the origin, as shown in the figure. • Along any ray from the origin, a homogeneous function deﬁnes a power function. Such a function is an equation showing the relationship between the input of two factors (K and L) into a production process, and the level of output (Q), in which the elasticity of substitution between two factors is equal to one. The sum of the two exponents indicates the returns to scale: (i) If α + β > 1, the production function exhibits increasing returns to scale. First, we can express the function, Q = f (K,L) in either of two alternative forms. Economics, Homogeneous Production Function, Production Function. An implication of the homogeneity of f, which you are not asked to prove, is that the partial derivatives f' x and f' y with respect to the two inputs are homogeneous of degree zero. The production function is said to be homogeneous when the elasticity of substitution is equal to one. Since the MRTS is the slope of the isoquant, a linearly homogeneous production function generates isoquants that are parallel along a ray through the origin. Since input prices do not change, the slope of the new isoquant must be equal to the slope of the original one. Share Your Word File Homothetic production functions have the property that f(x) = f(y) implies f(λx) = f(λy). Let be a homogeneous production function with inputs , . Since output has increased by 50%, the inputs will also increase by 50% from 10 units of labour to 15 and from 5 units of capital to 7.5. 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. Cobb-Douglas Production Function Definition: The Cobb-Douglas Production Function, given by Charles W. Cobb and Paul H. Douglas is a linear homogeneous production function, which implies, that the factors of production can be substituted for one another up to a certain extent only. Suppose, the production is of the following type: It exhibits constant return to scale because α = 0.75 and β = 0.25 and α + β = 1. It has an important property. Linear Homogeneous Production Function The Linear Homogeneous Production Function implies that fall the factors of’production are increased in slime proportion. If λ equals 3, then a tripling of the inputs will lead to a tripling of output. Show that the production function z=\ln \left(x^a y^{1 a} \right) is homothetic, even though it is not homogeneous. That is. Such a production function is called linear homogeneous production function. Your email address will not be published. If n< 1 DRS prevails. It is important to. (ii) If α + β = 1, there are constant returns to scale. The exponent, n, denotes the degree of homogeneity. Typically economists and researchers work with homogeneous production function.
