Suppose that the production function of a country is given by Y=K3L0.7, where Y is output, L is labour, and K is capital. a)What is the return to scale property of the production function? B)What will happen to output if we double the use of capital and labour? C)Write the production function as a relationship between output per worker and capital per worker.A Firm's Optimization with CES Production Function The Constant Elasticity of Substitution (CES) production function is a flexible way to describe how a firm combines capital and labor to produce output, allowing for different levels of substitutability between the two inputs. The elasticity of substitution, denoted by σ, measures how easily the firm can substitute capital for labor (or vice versa) while maintaining the same output level. The parameter p is related to the elasticity of substitution by the formula σ = 1/(1 - p). Now, let's consider a firm that operates for two periods (t and t + 1) and produces output according to the CES production function: F(Kt, Nt) = [aK{ + (1 − a)N]¹º 0A. Explain how MP = decreasing within the Cobb - Douglas function ( explain the functions and their variables ) 2.45 2.65 B. The company Tres Monjitas faces the following production function : Q = L K and has the following prices of inputs : PL = $ 10 and PK = $ 20 . Estimate the Cobb - function Douglass (Get L relative to K).For the production function q = f(K, L) the ratio of the percentage change on K/L with percentage change on PK/PL is called elasticity of substitution. Write down a constant returns to scale Cobb-Douglas production function and find its elasticity of substitution for the K = 10, L = 7, PK = 4 and PL = 3 levels.Can someone help me to explain and have the assumptions and graphs here?Please dont provide answer in handwritten solution...Find the elasticity of scale and the elasticity of substitution for the CES production function: 1 1 f(x₁, x₂) = (x³ + x2)³.

Which of the following statements is true? If inputs are doubled and output doubles, this is called increasing returns to scale. If inputs are doubled and output doubles, this is called constant returns to scale. If inputs are tripled and output doubles, this is called increasing returns to scale. If inputs are doubled and output doubles, this is called decreasing returns to scale. If inputs are tripled and output doubles, this is called constant returns to scaleQ1.
