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...

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 investigate the effects of central bank interventions (CBI) in a noise trading model with chartists and fundamentalists. We first estimate a model in which chartists extrapolate past returns and fundamentalists forecast a mean reverting dynamics of the exchange rate towards a...

We test the hypothesis that the government bond markets in the Eurozone are more fragile and more susceptible to self-fulfilling liquidity crises than in stand-alone countries. We find evidence that a significant part of the surge in the spreads of the PIGS countries in the Eurozone during...

In this paper we extend the behavioral macroeconomic model as proposed by De Grauwe (2012) to include a banking sector. The behavioral model takes the view that agents have limited cognitive limitations. As a result, it is rational to use simple forecasting rules and to subject the use of these...

We analyze the similarities and the differences in the fragility of the European Monetary system (EMS) and the Eurozone. We test the hypothesis that in the EMS the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets while in the Eurozone it was...

The sovereign debt crisis has made it clear that central banking is more than keeping inflation low. Central banks are also responsible for financial stability. An essential tool in maintaining financial stability is provided by the capacity of the central bank to be the lender of last resort in...

The ECB has been arguing in the past that since there is no trade-off between price stability and financial stability, the pursuit of price stability is the best a central bank can do to also maintain financial stability. We argue that there is a potential trade-off between price stability and...
