Production Functions: Cobb-Douglas, Interfirm, Intrafirm

Informacyjne uwarunkowania wykorzystania modeli ekonomicznych w badaniu relacji gospodarka – środowisko przyrodnicze (na przykładzie modelu funkcji produkcji)

“…Sama funkcja typu Cobb-Douglasa znalazła również zastosowanie w analizie mikroekonomicznej [Reder, 1943;Bronfenbrenner, 1944]. Jednocześnie dla klasy funkcji mikroekonomicznych zredukowano problem homogeniczności czynników produkcji uwzględnia-nych w funkcjach produkcji.…”

Agricultural Productivity and Economic Policies

“…Issues related to the dependence of the frontier on fixed inputs had been discussed in the literature on interfirm and intrafirm production functions and related issues, Reder (1943), Bronfenbrenner (1944), Smith (1945), and more recently formulated for empirical analysis in the form of the Putty-Clay production functions (Fuss 1977 "Thus defined, the metaproduction may appear to be the same as the innovation possibility curve advanced in Figure 4-2 in the previous chapter. In fact, we consider the metaproduction function an operational definition of the innovation possibility curve-operational in the sense that it can be measured empirically from observable production data.…”

On Exact Multicollinearity and the Estimation of the Cobb‐Douglas Production Function

“…For k inputs, there would be (k-l) identities in (2). When nearly exact multicollinearity exists, the equations in (2) could be estimated by least squares.…”

“…For k inputs, there would be (k-l) identities in (2). When nearly exact multicollinearity exists, the equations in (2) could be estimated by least squares. A common practice when the two input variables are found to be perfectly correlated involves dividing the dependent variable and the remaining independent variable by one of the two perfectly correlated inputs and estimating an equation based on the averages.…”
