2. In this problem, we will do a calibration exercise similar to the one in Lucas (JME, 1988), pp. 26-27. Suppose that we have the following parameter values from data or other studies: (a) Following Lucas, use the equilibrium solution of the model to calibrate (the exponent on ha in the production function) and (the efficiency of investment in human capital). (b) For the following three values of (the inverse of the intertemporal elasticity of substitution), ={0.5,1,2} compute the corresponding three values for each of the following parameters: (the discount rate); (the optimal growth rate of human capital); and 1u (the optimal fraction of time allocated to human capital accumulation).
