. The text showed that the marginal
products for the CobbDouglas production function are:
MPL = (1 )Y/L.
MPK = Y/K.
Competitive profit-maximizing firms hire labor until its marginal produc

Problem 1: The Aggregate Production Function
In Lecture 1 we considered the aggregate production function with capital and labor.
Assume now that there are three factors: K is capital (the number of machines),

a) The production function in the Solow growth model is Y = f(K,L), or expressed in terms of
output per worker, y = f(k). If a war reduces the labor force through casualties, the L falls but
Capital-labor ratio k = K
