We introduce the real exchange rate volatility curve as a useful device to understand the role of price stickiness in accounting for deviations from the Law of One Price at the sector level. In the presence of both nominal and real shocks, the theory predicts that the real exchange rate...

The World Bank has developed a novel method for measuring countries’ connectivity in global networks and has applied it to the global air transport network. “Connectivity” in this context is defined as a country’s relative position in that network in terms of the total “push” and...

We study the role of exchange rates in industrial policy. We construct an open-economy macroeconomic framework with production externalities and show that the desirability of these policies critically depends on the dynamic patterns of externalities. When they are stronger in earlier stages of...

This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

This paper considers the general equilibrium relationship between exchange rates and global imbalances. It emphasizes that the exchange rate is not a primitive but an equilibrium price determined by the policy mix. It uses extensions of the two-country Obstfeld-Rogoff model to analyze the...

Which are the main frictions and driving forces of business cycle dynamics in a small open economy? To answer this question we extend what is becoming the standard new Keynesian model in three dimensions. First, we incorporate frictions in the financing of the capital stock. Second, we model...

Over the past decade, geopolitical developments - and the policy responses to these by major economies around the world - have challenged economic openness and the process of globalisation, with implications for the economic environment in which central banks operate. The return of war to Europe...

Exchange rate misalignment may exacerbate the costs of transition for the former socialist economies. We examine the exchange rate policies of Poland, calculate the real exchange rate based upon the CPI, PPI, wage rates and profits and then calculate misalignment. Purchasing power parity...

The last few years have seen a significant re-evaluation of the models used to analyze crises in emerging markets. Recent models typically stress financial constraints or distorted financial incentives. While this certainly represents progress, these models share a weakness with the earlier...

The IMF began to play a prominent role in low-income countries in the late 1970s and 1980s when many countries faced overvalued exchange rates, growing budget deficits, high inflation, and low reserves. But times have changed, and many low-income countries no longer face these problems and do...
