We study optimal monetary policy in a flexible state-dependent pricing framework, in which monopolistic competition and stochastic menu costs are the only distortions. We show analytically that it is optimal to commit to zero inflation in the long run. Moreover, our numerical simulations...

In this paper we provide a new explanation for the increase in world trade over the last two decades. We show analytically in a general equilibrium model with heterogeneous firms that a fall in variable offshoring costs boosts trade in differentiated final goods through an intra-industry...

In this paper, I investigate the welfare effects that developed countries experience after productivity improvements occur in their emerging trading partners, using a two-country model featuring pro-competitive effects of trade and asymmetries in technology. I model the technology advantage of...

Audiovisual services such as music and movies in digital formats have gained substantial importance over the last decade. This paper analyses audiovisual services in a gravity model framework. In particular, we explore the role of virtual proximity -- a new proxy for cultural proximity based on...

Empirical studies of the "shoe-leather" costs of inflation are typically computed using M1 as a measure of money. Yet, official data on M1 includes all currency issued, regardless of the country of residence of the holder. Using monetary data adjusted for US dollars abroad, we show that the...

We show that the composition of imports has important implications for the optimal volatility of the exchange rate. Using input-output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported...

The purpose of this paper is to evaluate the empirical relevance of real convergence on the process of nominal convergence for the new EU Member States. We discuss two of the main channels through which real convergence could affect relative prices with respect to the euro area: productivity...

Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and...

This paper contributes to the literature on the impact of EMU on trade, adding two new elements. First, we propose a theoretical model for explaining how the euro could have increased trade by the large amounts found in the empirical literature. Second, we propose a sectoral dataset to test the...

This paper examines the impact of downward wage rigidity (nominal and real) on optimal steady-state inflation. For this purpose, we extend the workhorse model of Erceg, Henderson and Levin (2000) by introducing asymmetric menu costs for wage setting. We estimate the key parameters by simulated...
