Consider an economy in which the representative consumer preferences are described by U(C, l) = 2C^(1/2) + 3l. The total number of hours available to the representative consumer is h = 1, and the market real wage is w. The representative firm produces the final consumption good using the technology function Y = N 1/2 , where N is the labour. Additionally, assume that there is no government in the economy, that is G=0. 1. Describe the relationship between MRSl/C,...
