The existing literature has shown that less political uncertainty, or more central bank transparency, may worsen macroeconomic performance by raising the nominal wage. We extend this analysis to a non-bayesian framework, where there is some aversion to ambiguity. We show that the result found in...

We underline that some results obtained in the literature on central bank transparency may be quite different when we take a non-Bayesian approach to uncertainty, where "ambiguity" is taken into account. We consider some specific argument of the literature (obtained under a Bayesian approach),...

We revisit the link between crises and exchange rate regimes (ERR). Using a panel of 90 developed and developing countries over the period 1980-2009, we find that corner ERR are not more prone to crises compared to intermediate ERR. This finding holds for different types of crises (banking,...

This paper proposes theoretical and empirical analysis of the effect of capital controls and alternative exchange rate regimes on the patterns of speculative capital. I argue that the exchange rate regime and its interaction with the monetary regime can explain the patterns of speculative...

This paper offers a framework to study commitment and cooperation issues in games with multiple policymakers. To reconcile some puzzles in the recent literature on the nature of policy interactions among nations, we prove that games characterized by different commitment and cooperation schemes...
