This paper studies the implication, in terms of welfare and monetary policy, of unequal degrees of competition across members of a currency area. We look at two ways in which the degree of competition in the market for goods can affect welfare in a currency area. One is through different average...

Recent analyses of transaction-level datasets have generated new stylized facts on price setting and greatly influenced the empirical macroeconomics literature. This work has uncovered marked heterogeneity in price stickiness, demonstrated that even non-zero price changes do not fully "pass...

Emerging market economies, which have much of their growth ahead of them, either run or should run persistent current account deficits in order to smooth consumption intertemporally. The counterpart of these deficits is their dependence on capital inflows, which can suddenly stop. We make two...

This paper analyses firm's pricing-to-market decisions in vertically differentiated industries. We first present a model featuring firms that sell goods of heterogeneous quality levels to consumers who are heterogeneous in their income and thus their marginal willingness to pay for quality...

Using panel data on military spending for 125 countries, we document new facts about the effects of changes in government purchases on the real exchange rate, consumption, and current accounts in both advanced and developing countries. While an increase in government purchases causes real...

Existent literature is by no means conclusive on the effects of trade finance on trade and the economy. We propose a suitable framework to explore the linkages between international trade and finance based on an international real business cycle model where firms require external finance to...

Most countries in the world are not at the technological frontier, yet their economies grow and fluctuate. This paper sets up a quantitative model of endogenous growth with business cycle fluctuations to analyze the medium frequency fluctuations in non-frontier countries. The growth mechanism is...

This paper studies a New Keynesian model of a two-country world with a zero lower bound (ZLB) constraint for nominal interest rates. A floating exchange rate regime is assumed. The presence of the ZLB generates multiple equilibria. The two countries can experience recurrent liquidity traps...

To investigate the dynamic effect of external shocks on an oil exporting economy, we estimate, using Bayesian approach, a DSGE model based on the features of the Algerian economy. The main purpose is to investigate the dynamic effect of four external shocks (oil price shock, USD/EUR exchange...

This paper aims to highlight key limitations of “The Economist” magazine's Big Mac Index (BMI). The Economist markets the BMI as a tool to determine valuation of currencies. This paper shows that the BMI is a misleading measure of currency valuation for economies whose markets are...
