This paper investigates the relationship between the euro-dollar exchange rate and its underlying fundamentals. First, we develop a simple theoretical model in which chartists and fundamentalists interact. This model predicts the existence of different regimes, and thus non-linearities in the...

This paper explores the impact of the exchange rate regime on inflation and output in the Central and Eastern European (CEE) EU candidate countries. The panel estimations for the period between 1994 and 2002 show that de facto measures of exchange rate stability have a better explanatory power...

We develop a simple model of the foreign exchange market 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...

In this paper we develop a model of the exchange rate. The existence of transactions costs introduces an important non-linearity. Agents have different beliefs about the future exchange rate. We show that this simple model creates great complexity in the market which is characterised by the fact...

We analyse the workings of a simple non-linear exchange rate model in which agents hold different beliefs about the underlying model. We distinguish between "chartists" and "fundamentalists". The non-linearities in the model originate from transactions costs and from the existence of non-linear...

We test whether the relationship between the nominal exchange rate and the news in its underlying fundamentals has non-linear features. In order to do so, we develop a Markov switching model and apply it to a sample of low and high inflation countries. The empirical analysis shows that for the...

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...

We present a simple behavioral model with chartists and fundamentalists and analyze their trading behavior in a floating regime and in a target zone regime. Regarding the floating regime the model replicates the well-known stylized facts like excessive volatility, fat tails, volatility...

This paper explores the conflict of real and monetary convergence during the EMU run-up of the Central and Eastern European new EU member states. Based on a Balassa-Samuelson model of productivity driven inflation, it finds a high probability of higher inflation in the new member states. It...

In this paper it is shown that relatively simple models are capable of generating exchange rate movements that, at least in the short run, are largely disconnected from their fundamental values. The essential ingredient of such models is the hypothesis that economic agents use different...
