Recent crises have seen very large spikes in asset price risk without dramatic shiftsin fundamentals. We propose an explanation for these risk panics based on selffullling shifts in risk made possible by a negative link between the current assetprice and risk about the future asset price. This...

We develop a new theory of international capital flows based on dispersed in-formation across individual investors. There is extensive evidence of informationheterogeneity within and across countries, which has proven critical to under-standing asset price behavior. We introduce information...

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter’s invoicing choice reflects structural aspects of her industry, such as market share and...

The paper analyses the impact of financial liberalization and reform in emerging markets on the dynamics of capital flows to these markets, using a simple model of international investors' behaviour. We first show that the gradual nature of liberalization, combined with the cost of absorbing...

We develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare. An important feature of the model is deviations from purchasing power parity, caused by rigid price setting in buyers' currency. We find the following. First, exchange rate...

This paper examines the relationship between the exchange rate regime and trade flows using a general equilibrium model based on Bacchetta and van Wincoop (AER, 2000). We show that in general the link between trade and the exchange rate regime is ambiguous and that it depends in particular on...

Nominal rigidities due to menu costs have become a standard element in closed economy macroeconomic modeling. 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 set...

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...

Empirical evidence shows that observed macroeconomic fundamentals have little explanatory power for nominal exchange rates (the exchange rate determination puzzle). On the other hand, the recent "microstructure approach to exchange rates" has shown that most exchange rate volatility at short to...

While empirical evidence finds only a weak relationship between nominal exchange rates and macroeconomic fundamentals, forex markets participants often attribute exchange rate movements to a macroeconomic variable. The variables that matter, however, appear to change over time and some variable...
