The wage for workers in a competitive market is initially $10 and rent, the cost of capital (also rented in a competitive market), is initially $5. Now suppose that wages decrease to $8 and rent decreases to $2.

a) Describe how the scale effect changes a firm's use of labor and capital.

b) Describe how the substitution effect changes a firm's use of labor and capital.

c) Overall will a firm hire more or fewer workers? Will a firm rent more or less capital?

d) Will a firm change its production technology given the changes in w and r?

a. This directly affects product costs when the costs of both input variables rise. i.e. in the same proprotation to the manufacturer the price of the commodity will be increased. Labor avialiability will rise on the market, and the availability of capital will also increase. In the best combination of these two inputs, however, the use of both factors will be reduced by the business in the hope of reducing total costs.

b. The proportion of labor will increase as much as the proportion of capital if both are complete substitutes. In other words, more labour is used by capital replacement and the overall cost of the product can be minimized.

c. More and less capital go to a company. The higher labor cost is higher than the higher labor cost and they are perfect supplements.

d. Indeed, this business is now transforming into a service company where most of the works are only performed with men

In the labor market the wage rate requested by workers will generally depend on workers’ expected price Pe which is to prevail in the future, the current unemployment rate u, and a variable z that represents the unemployment benefits package. This defines the wage-setting relationship: W = PeF(u,z). At the same time, firms define the price-setting relationship: P = (1+m)W, where m is the markup of goods prices over wage rate. (1) Suppose we know the functional form F(u,z) =...
