This resulted in a model of the macroeconomy as consisting of a single consumer, who lives for ever, consuming the output of the economy, which is a single good produced in a single firm, which he owns and in which he is the only employee, which pays him both profits equivalent to the marginal product of capital and a wage equivalent to the marginal product of labor, to which he decides how much labor to supply by solving a utility function that maximizes his utility over an infinite time horizon, which he rationally expects and therefore correctly predicts. The economy would always be in equilibrium except for the impact of unexpected ‘technology shocks’ that change the firm’s productive capabilities (or his consumption preferences) and thus temporarily cause the single capitalist/worker/consumer to alter his working hours. Any reduction in working hours is a voluntary act, so the representative agent is never involuntarily unemployed, he’s just taking more leisure. And there are no banks, no debt, and indeed no money in this model.You think I’m joking? I wish I was.
