A homothetic function is a monotonie transformation of a function that is homogeneous of degree 1. In other words, /(x) is homothetic if and only if it can be written as /(x) = g(h(x)) where h(-) is homogeneous of degree 1 and g(-) is a monotonie function. See Figure 1.7 for a geometric interpretation. A B. Figure Homogeneous and homothetic ...

Homogeneous Production Function| Economics

A function is homogenous of order k if. f ( t x, t y) = t k f ( x, y). A function is homothetic if it is a monotonic transformation of a homogenous function (note that this second function does not need to be homogenous itself). Consider now the function: f ( x, y) = x a y b. This is homogenous, since. f ( t x, t y) = ( t x) a ( t y) b = t a + b x a y b = t a + b f ( x, y).

Homogeneous, in English, means "of the same kind" For example "Homogenized Milk" has the fatty parts spread evenly through the milk (rather than having milk with a fatty layer on top.) Homogeneous applies to functions like f(x) , f(x,y,z) etc, it is a general idea.

Homothetic preferences - Wikipedia

A homogeneous production function is also homothetic—rather, it is a special case of homothetic production functions. In Fig. 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.

Hence, geometrically, if the ordering is homothetic, then for all x ∈ E and λ > 0 $$L(Xx)=\left\{Xy:y\in L(x)\right\}.$$ This chapter was originally published in The New Palgrave: A Dictionary of Economics , 1st edition, 1987.

HOMOTHETIC FUNCTIONS WITH ALLEN’S PERSPECTIVE AND

Let f be a real-valued function defined on En, then f is homothetic if it can be written as .f (x) = h(g(x)), (2) where g is homogeneous and h is a continuous, positive-valued and nondecreasing. In a recently published text (, p. 344), Lancaster defined a function to be homothetic if it satisfies the following condition: CONDITION K.

Homogeneous and Homothetic Functions - ResearchGate

The aim of this work is to investigate a production model recently studied in [] under the name of quasi-homogeneous two-factor production function, as a natural generalization of the family of classical homogeneous production functions with two inputs (labor and capital).It is important to highlight that the quasi-homogeneity property of production functions was originally considered in ...

This video shows how to determine whether the production function is homogeneous and, if it is, the degree of homogeneity. I also show how homogeneity relates to returns to scale.

The following shows that, in additively separable utility functions, any deviation from CES would give us non-homothetic preferences. Proposition: Suppose that the utility function, U RJ R: , is quasi-concave, increasing, and separable, J j U x u j x j 1 ( ) ( ). Then, it is homothetic if and only if j j j j x u x 1 ( ) ( ) 1 for θ> 0, ≠ 1 ...

Returns to Scale, Homogeneous Functions, and Euler's Theorem 161 However, production within an agricultural setting normally takes place with many more than two inputs. Each of the inputs in the production process may differ with respect to whether or not the amount that is used can be changed within a specific period.
