Happy hour economics, or how an increase in demand can produce a decrease in price
The standard supply-and-demand model is typically an economist?s most important analytical tool, but in some situations it does not capture the features of interest. For example, during ?happy hour,? bars near workplaces sell a higher-than-usual quantity of alcoholic beverages at a lower-than-usual price. This practice makes little sense using the standard competitive model, but an alternative model?the model of monopolistic competition?provides the needed analytic framework. ; This article provides a step-by-step construction of a monopolistic competition model in which many firms each ...

Production interdependence and welfare
The international welfare effects of a country?s monetary policy shocks have been controversial in the literature. While a unilateral monetary expansion increases the production efficiency in each country, it affects terms of trade in favor of one country against another depending on the currencies of price setting. We show that the increased world production interdependence magnifies the efficiency-improvement effect while dampening the terms-of-trade effect. As a consequence, a unilateral monetary expansion can be mutually beneficial and thus Pareto improving regardless of in which currency ...

Effects of Credit Supply on Unemployment and Inequality
The Great Recession, which was preceded by the financial crisis, resulted in higher unemployment and inequality. We propose a simple model where firms producing varieties face labor-market frictions and credit constraints. In the model, tighter credit leads to lower output, lower number of vacancies, and higher directed-search unemployment. Where workers are more productive at higher levels of firm output, lower credit supply increases firm capital intensity, raises inequality by increasing the rental of capital relative to the wage, and has an ambiguous effect on welfare. At initial high ...

Benefits and spillovers of greater competition in Europe: a macroeconomic assessment
We estimate the macroeconomic benefits and international spillovers of an increase in competition using a general-equilibrium simulation model with nominal rigidities and monopolistic competition in product and labor markets. We draw three conclusions after calibrating the model to the euro area against the rest of the industrial world. First, greater competition produces large effects on macroeconomic performance, as measured by standard indicators. In particular, we show that differences in competition can account for more than half of the current gap in GDP per capita between the euro area ...

Vertical production and trade interdependence and welfare
The authors study international transmissions and welfare implications of monetary shocks in a two-country world with multiple stages of production and multiple border-crossings of intermediate goods. This empirically relevant feature is important, as it has opposite implications for two external spillover effects of a unilateral monetary expansion. If all production and trade are assumed to occur in a single stage, the conflict-of-interest terms-of-trade effect tends to dominate the common-interest efficiency-improvement effect for reasonable parameter values, so that the international ...
