Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...

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...

This study explores the factors driving the observed movements of the profit share in several major industrialised countries (France, Germany, United States, United Kingdom and Japan) over the period 1970-2000. Within the group of countries we study, both the level and the fluctuations of the...

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...

Economic theory often assumes that the opportunity costs of having a child and financial constraints have a simultaneous but opposite influence on fertility. This empirical paper aims to test the concomitance of these effects using the answers to an original survey carried out in 2003 amongst...

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

Numerous economic studies have highlighted that ICT investment expenditure appears to be greater in the field of services, and above all in certain activities such as financial services and wholesale trade, than in industry. This analysis examines whether the investment data compiled by national...

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...

The correlation matrix between break-even inflation rate movements and real interest rate movements across several countries shows puzzling features. Correlation is significantly positive for nearly all cross-border pairs whereas it is nil, positive or negative unsystematically within countries....
