The traditional criticism notwithstanding, we show that social mobility can, in principle, explain political income redistributions. Nonetheless, the social-mobility argument for redistribution is not satisfactory, as actual transition probabilities are not consistent with order-preserving...

A vast literature analyzes the real effects of price-adjustment costs assuming that quantity adjustments are costless. In this paper, we analyze whether the presence of quantity-adjustments costs, which presumably are significant, change the traditional results on the impact of inflation. In...

This paper explores how a minimum wage affects a firm's behavior with a competitive labor market and an uncertain export cost. The model provides several novel insights which are consistent with recent empirical evidence. Thus, a minimum wage increases an exporter's foreign-market size and may...

This paper analyzes the optimal adjustment strategy of an inventory-holding firm facing price- and quantity-adjustment costs in an inflationary environment. The model nests both the original menu-cost model that allows production to be costlessly adjusted, and the later model that includes...

With fixed costs of price and quantity adjustment, output effects of inflation depend on the elasticity of the firm's marginal real revenue. If the elasticity always exceeds minus unity, then output decreases with inflation, while if the elasticity is always less than minus unity, then output...

In many countries, an expired labor contract is automatically extended during the often protracted delay before the new contract is signed. Our theoretical model focuses on macroeconomic factors in explaining the delay. It emphasizes the importance of the realized nominal and real shocks, and of...

This paper explains why a union and a firm might settle on a contract duration that may later be extended and characterizes the optimal backpay for the holdout period. It is shown that the choice between concluding a shorter contract that may be extended and immediately concluding a longer...

Contrary to widespread belief, we show that low-pay workers might not generally prefer that the minimum wage rate be increased to a level where the labor demand is unitary elastic. Rather, there exists a critical value of elasticity of labor demand such that increases in the minimum wage rate...
