We document the presence of both small and large price changes in individual price records from the CPI in France and the US. After correcting for measurement error and cross-section heterogeneity, the size-distribution of price changes has a positive excess kurtosis. We propose an analytical...

This paper presents the recent developments of macro-econometric modelling and discusses their advantages and limits. We first present the Sims critique and the Lucas critique. These two critiques have opened two new ways of macro-modelling. On the one hand, the Structural VAR approach allows to...

This paper presents a model of the portfolio and financing adjustments of U.S. banks over the business cycle. At the core of the model is a moral hazard problem between depositors/bank regulators and stockholders. The solution to this problem takes the form of shared management of the bank....

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...

We use the ECB Survey of Professional Forecasters to characterize the dynamics of expectations at the micro level. We find that forecasters (i) have predictable forecast errors; (ii) disagree; (iii) fail to systematically update their forecasts in the wake of new information; (iv) disagree even...

We develop a dynamic general equilibrium model for the positive and normative analysis of macroprudential policies. Optimizing financial intermediaries allocate their scarce net worth together with funds raised from saving households across two lending activities, mortgage and corporate lending....

This paper provides the conditions under which small enough private uncertainty on an aggregate endogenous state of the economy can invalidate uniqueness of the equilibrium. The main result is presented in a fully microfounded macroeconomic model where agents learn from arising prices. The...
