They have developed this equation between years 1927-1947. We show that the large elasticity of substitution between capital and labor estimated in the literature on average, 0.9, can be explained by three factors. It serves as an indicator of the state of technology. Actually, the parameter A is the efficiency parameter. This production function is developed by Paul Douglas and Charles Cobb, as also shown in the image too. Cobb-Douglas (C-D) production function is of the form Q AL K (8.100) where L quantity used of labour ADVERTISEMENTS: K quantity used of capital Q quantity of output produced A,, positive constants. This function deals with the relationship between input and output used to produce a product.
$$\hat u(x_1,x_2) = \ln(x_1^a x_2^b) = a \ln x_1 + b \ln x_2$$ CobbDouglas production function is used in both microeconomics and macroeconomics. However, we will often transform this function by taking the natural log, which allows us to transform exponents into coefficients: Cobb-Douglas production function showed the level of production is explained by capital, labor and other determinants of economic growth 19. The general form of a Cobb-Douglas function over two goods is where Y is total output, and A, K, H, and L are total factor productivity, the stock of physical and human capitals, and the amount. We show that the large elasticity of substitution between capital and labor estimated in the literature on. A simple aggregated CobbDouglas production function, with no natural resources, was the starting point for the estimation of the stock of human capital in the 19th century in Brazil. The Cobb-Douglas functional form was first proposed as a production function in a macroeconomic setting, but its mathematical properties are also useful as a utility function describing goods which are neither complements nor substitutes. : Death to the Cobb-Douglas Production Function.
