For few years, the increasing size of available economic and financial databases has led econometricians to develop and adapt new methods in order to efficiently summarize information contained in those large datasets. Among those methods, dynamic factor models have known a rapid development and...

An empirical analysis is conducted on two panels of 18 OECD countries to test whether the elasticity of hourly productivity to working time is negative and decreasing with working time itself. If so, the decreasing returns on working time could be indicative of a fatigue effect that increases...

Hourly labour productivity levels in a number of European countries are thought to be very close to, or possibly even higher than the level 'observed' in the United States. At the same time, however, there are big differentials between hours worked and/or employment rates in these countries and...

Estimating returns to hours worked and the employment rate provides us with an original interpretation of changes in US productivity and other industrialized countries' catch-up with US productivity levels over recent decades

Using a novel dataset from a large supermarket retailer in a European country that never engages in temporary sales, we establish that prices are actually as sticky as regular prices. Circumventing the debate on whether sales have to be included or excluded from price adjustments, we find...

We quantify the capital shortfall that results from a global financial crisis by using a macrofinance dynamic stochastic general equilibrium model that captures the interactions between the financial and real sectors of the economy. We show that a crisis similar to that observed in 2008...

I provide a microfounded theory for one of the oldest, but so far informal, explanations of price rigidity: the kinked demand curve theory. Assuming that some customers observe at no cost only the price of the store they happen to be at gives rise to a kink in firms' demand curves: a price...

Using a unique panel design that enables to control for bank, firm, market and loan heterogeneities, we confirm that relationship lenders charge higher rates in good times and lower rates in bad times. However, we show that risky single-bank firms do not benefit from this insurance mechanism and...

The paper studies how parameter variation affects the decision rules of a DSGE model and structural inference. We provide diagnostics to detect parameter variations and to ascertain whether they are exogenous or endogenous. Identification and inferential distortions when a constant parameter...
