Suppose the supply curve of physicists is given by w = 10 + 5E, while the demand curve is given by w = 50 - 3E. Calculate the equilibrium wage and employment level. Suppose now that the demand for physicists increases to w = 70 - 3E. Assume the market is subject to cobwebs. Calculate the wage and employment level in each round as the wage and employment levels adjust to the demand shock. (Recall that each round occurs on the demand curve - when the firm posts a wage and hires workers). What is the new equilibrium wage and employment level?
