This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

The aim of this paper is to develop a continuous time exchange rate model that allows for heterogeneity of the agents' beliefs, in order to explore non-linearities and possible chaotic behaviour. The theoretical model contains an intrinsic non-linearity that gives rise to a jerk differential...

In 2002 Uruguay faced a sudden stop of international capital flows, inducing a deep financial crisis and a large devaluation of the peso. The real exchange rate depreciated and exports expanded. Paradoxically, export shares and real exchange rates negatively correlate among Uruguayan exporters...

This paper addresses difficulties in modelling exchange rates in South Africa. Real exchange rate models of earlier research seem to be sensitive to the sample period considered, alternative variable definition, data frequency and estimation methods. Alternative exchange rate models proposed in...

We develop a simple model of the exchange rate in which agents optimize their portfolio and use different forecasting rules. They check the profitability of these rules ex post and select the more profitable one. This model produces two kinds of equilibria, a fundamental and a bubble one. In a...

This paper describes and analyzes automated intervention of a target zone. Unusually detailed information about the order book allows studying intervention effects in a microstructure approach. We find in our sample that intervention increases exchange rate volatility (and spread) for the next...

This paper examines heterogeneity in exchange rate expectations. Whereas agents' heterogeneity is key in modern exchange rate models, evidence on determinants of heterogeneity is weak so far. Our sample, covering expectations from about 300 forecasters over 15 years, shows remarkable time...

This paper studies drivers of high-frequency (daily) dynamics of the South African rand vis-à-vis the dollar from January 2001 to July 2007. We find strong nonlinear effects of commodity prices, perceived country and emerging market risk premium and changes in the dollar-euro exchange rate on...

For the academic audience, this paper presents the outcome of a well-identified, large change in the monetary policy rule from the lens of a standard New Keynesian model and asks whether the model properly captures the effects. For policymakers, it presents a cautionary tale of the dismal...

We estimate exchange rate elasticities of international tourism. We show that, in addition to the bilateral exchange rate, the exchange rate between the tourism origin country vis-à-vis the U.S. dollar is an important driver of tourism flows, indicating a strong role of U.S. dollar pricing. The...
