Nominal rigidities due to menu costs have become a standard element in closed economy macroeconomic modelling. The ‘New Open Economy Macroeconomics’ literature has investigated the implications of nominal rigidities in an open economy context and found that the currency in which prices are...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

As the European Community (EC) unifies its financial markets and fixes its exchange rates, the EFTA countries are liberalizing capital movements to the same extent. The EFTA countries thus face a decision on financial markets and exchange rate policy: should they essentially join the European...

Standard macro models cannot explain why real exchange rates are volatile and disconnected from macro aggregates. Recent research argues that models with persistent growth rate shocks and recursive preferences can solve that puzzle. I show that this result is highly sensitive to the structure of...

While the global financial crisis was centered in the United States, it led to a surprising appreciation in the dollar, suggesting global dollar illiquidity. In response, the Federal Reserve partnered with other central banks to inject dollars into the international financial system. Empirical...

We investigate the predictive information content in foreign exchange volatility risk premia for exchange rate returns. The volatility risk premium is the difference between realized volatility and a model-free measure of expected volatility that is derived from currency options, and reflects...

Using multivariate unit root test methods, this Paper investigates the Purchasing Power Parity (PPP) hypothesis at the sectoral level across six European countries over the last seventeen years. Evidence of mean reversion toward PPP is found for the relative prices of some sectors and countries....

An independent central bank can manage its balance sheet and its capital so as to commit itself to a depreciation of its currency and an exchange-rate peg. This way, the central bank can implement the optimal escape from a liquidity trap, which involves a commitment to higher future inflation....

The paper examines the transmission mechanism of monetary policy in an open economy with and without a binding zero bound on nominal interest rates. In particular, a foolproof way of escaping from a liquidity trap is suggested, consisting of a price-level target path, a devaluation of the...

It is well known that the extent of pass-through of exchange rate changes to consumer prices is much lower than to import prices. One explanation is local distribution costs. Here we consider an alternative, complementary explanation based on the optimal pricing strategies of firms. We consider...
