Question

Problem 4 Consider the production model in chapter 4. Assume that, in the production function, the exponents orn capital and labor are respectively 3/5 and 2/5. a) Write down the equation of the model and mark the endogenous and exogenous variables/parameters How does the firm decide how much labor to hire and capital to rent? Show and explain. What does it mean to solve the model? Solve the model reporting all the steps. What is the equilibrium? Define and report the equilibrium in this example using also a graph How does the equilibrium rental rate of capital change if 2/3 of the capital stock in the economy is destroyed by a war? By how much does the rental rate of capital change? b) c) d)
