Question 1 (16 points) The aggregate production function in the Romer model describes how the capital stock, K, and labor, Ly, combine to produce output, Y, using the stock of ideas, A: YK" (ALy) (1) O 0 < a < 1. o L-Ly + LA=(1-SR)L+SRL (labor force to produce output + labor force to produce ideas). O SR is a constant fraction of the labor force. Labor grows exponentially at some constant and exogenous rate: = n o Along a balanced growth path,
