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 ...

Understanding Changes in Exchange Rate Pass-Through
Recent research suggests that there has been a decline in the extent to which firms "pass through" changes in exchange rates to prices. Beyond providing further evidence in support of this claim, this paper proposes an explanation for the phenomenon. It then presents empirical evidence of a structural break during the 1990s in the relationship between the real exchange rate and CPI inflation for a set of 14 OECD countries. It is suggested that the recent reduction in the real exchange rate pass-through can be attributed in part to the low-inflation environment of the 1990s.

Are Supply Networks Efficiently Resilient?
We show that supply networks are inefficiently, and insufficiently, resilient. Upstream firms can expand their production capacity to hedge againstsupply and demand shocks. But the social benefits of such investments arenot internalized due to market power and market incompleteness. Upstreamfirms under-invest in capacity and resilience, passing-on the costs to downstreamfirms, and drive trade excessively towards the spot markets. There isa wedge between the market solution and a constrained optimal benchmark,which persists even without rare and large shocks. Policies designed to incentivize ...

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 ...

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 ...
