This paper shows that the reforms which expanded short-time work in France after the great 2008-2009 recession were largely to the benefit of large firms which are recurrent short-time work users. We argue that this expansion of short-time work is an inefficient way to provide insurance to...

Short-time work programs were revived by the Great Recession. To understand their operating mechanisms, Pierre Cahuc, Francis Kramarz & Sandra Nevoux first provide a model showing that short-time work may save jobs in firms hit by strong negative revenue shocks, but not in less severely-hit...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

This paper investigates the effect of export shocks on innovation. On the one hand a positive shock increases market size and therefore innovation incentives for all firms. On the other hand it increases competition as more firms enter the export market. This in turn reduces profits and...

In this paper, we identify two counteracting effects of credit access on productivity growth: on the one hand, better access to credit makes it easier for entrepreneurs to innovate; on the other hand, better credit access allows less efficient incumbent firms to remain longer on the market,...

We use a French firm-level panel data set over the period 1993-2004 to analyze the relationship between credit constraints and firms' R&D behavior over the business cycle. Our main results can be summarized as follows: (i) the share of R&D investment over total investment is countercyclical...

We study how strongly individuals respond to tax simplicity and how they learn about the complexities of the tax system. We use new French tax returns data on the self-employed from 1994 to 2012. France has three fiscal regimes for the self-employed, which differ in their monetary tax incentives...

Does regulation affect the pace and nature of innovation and if so, by how much? We builda tractable and quantifiable endogenous growth model with size-contingent regulations. Weapply this to population administrative firm panel data from France, where many labourregulations apply to firms with...

In this paper we use cross-state panel data to show that top income inequality is (at least partly) driven by innovation. We first establish a positive and significant correlation between various measures of innovativeness and top income inequality in cross-state panel regressions. Two distinct...

Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth. This paper uses the theory and methodology developed by Aghion et al. (2017) to quantify in the case of France how much of...
