We set up a model where asset price bubbles due to risk shifting can be moderated by capital requirements. However, imperfect information about the ratio of required capital, or, in the context of the sub-prime crisis, the extent of regulatory arbitrage, introduces uncertainty about the risk...

This paper quantifies the relative dominance of global currencies and the competitive structure of the international monetary system since 1825. I find the post-1945 experience of dollar hegemony to have no historical precedent. No currency has ever maintained such a large, long-lasting lead...

We analyse the redistribution channel of a money-financed versus debt-financed fiscal stimulus in a Borrower-Saver frammework. The redistribution channel is larger when we consider a money-financed fiscal stimulus. However, it generates also larger welfare losses than a debt-financed fiscal...

The advent and spread of information and communication technologies (ICTs) increase potential output growth. It is uncertain to what extent and for how long they do so. We use the term "new economy" (NE) to describe the acceleration in potential output growth and the attendant and partly...

We investigate the stability of M3 income velocity in the euro area. We apply a set of breakpoint procedures to examine this issue and conclude that at least one structural change occurred around 2000-2001. We also find evidence of another structural break around 1992-1993. These two breaks seem...

This article deals with the estimation of a time-varying coefficients equation with endogenous regressors. A non-parametric approach is proposed, combining the Generalized Method of Moments (GMM) with the smoothing splines litterature as in Hodrick and Prescott (1981). This new method is used to...

What factors cause banks to lend to the private sector in a bank-based financial system like the ones in place in Europe? In this paper we compare a traditional demand oriented model to a non-traditional capital budgeting model of bank lending based on movements in the equity cost of capital for...

In this paper, we try to illustrate the interest of the Bayesian approach for the evaluation of economic policies, often realised by analysing the response of the economy to a standard shock. We present a Stochastic Dynamic General Equilibrium model for the euro area. The Bayesian estimation...

In an otherwise unique-equilibrium model, agents are segmented into a few informational islands according to the signal they receive about others' expectations. Even if agents perfectly observe fundamentals, rational-exuberance equilibria (REX) can arise as they put weight on expectational...

Using newly assembled data on foreign exchange market intervention, we construct a daily index of exchange market pressure during the 1992-3 crisis in the European Monetary System. Using this index, we pinpoint when and where the crisis was most severe. Our analysis focuses on a neglected factor...
