Homogeneous Functions For any α∈R, a function f: Rn ++ →R is homogeneous of degree αif f(λx)=λαf(x) for all λ>0 and x∈Rn ++. A function is homogeneous if it is homogeneous of degree αfor some α∈R. Afunctionfis linearly homogenous if it is homogeneous of degree 1. • Along any ray from the origin, a homogeneous function deﬁnes a power function. If fis linearly homogeneous ...

A function which is homogeneous of degree 1 is said to be linearly homogeneous, or to display linear homogeneity. 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. So, this type of production function exhibits constant returns to scale over the entire range of output. In general, if ...

If that’s not self-explanatory, consult the good discussion of homogenous and homothetic functions at http://www.rmi.ge/~kade/Lectures... Graphically, a function is homothetic if the slopes of its level curves are all equal along a ray drawn from the origin – that is, if each level curve has the same shape as all the others, in the sense that one is simply a radial expansion of another.

This is homogenous, since $$f(tx, ty)=(tx)^a(ty)^b=t^{a+b}x^ay^b=t^{a+b}f(x, y).$$ Consider now the function $$g(z)=\log z$$ which is monotone. We have $$g(f(x, y))=\log(f(x, y))=\log(x^ay^b)=a\log x+b\log y$$ which is your first function. This is a monotone transformation of a homogenous function, so it is homothetic. Consider now $$f(x ... 20 Homogeneous and Homothetic Functions_百度文库 Homothetic functions, Monotonic Transformation, Cardinal vs Ordinal Utility, Marginal Rate of Substitution, Cobb Douglas example and more.

Homogeneous and Homothetic Functions | SpringerLink 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. Due to this, along rays coming from the origin, the slopes of the isoquants will be the same ... H&H Functions Notes - Handout 1 A Note on Homogeneous and ... Homothetic Production Functions.

Properties of the Linearly Homogeneous Production Function

that h(v(x)) = (h g)(u(x)) is a monotone transformation of a homogeneous function, that is, homothetic. But this is not hard: suppose z 1 >z 2.Then since gis monotone (increasing, let’s say - the proof is the same for decreasing, or for nonstrict monotonicity), g(z 1) >g(z 2). And since his also monotone, h(g(z 1)) >h(g(z 2)),sothat(h g) is in fact monotone. We now want to characterize the ...

0.1 Production functions with a single output 0.1.1 Homothetic and Homogeneous Production Functions Homothetic production functions have the property that f(x) = f(y) implies f(λx) = f(λy). Homogeneous production functions have the property that f(λx) = λkf(x) for some k. Homogeneity of degree one is constant returns to scale. Homoge-neous implies homothetic, but not conversely. Example f ...
