From the point of view of a profit-maximizing firm, the optimal number of working hours depends not only on the marginal productivity of hours but also on the marginal labour cost. This paper develops and assesses empirically a simple model of firms' decision making where productivity varies...

This paper uses Belgian firm-level data, covering the 1998-2006 period, to assess the impact on TFP growth of key labour force structural changes: ageing, feminisation and rise of educational attainment. Based on a Hellerstein-Neumark analytical framework, our work shows that an ageing workforce...

The aim of this paper is to develop and implement an analytical framework assessing whether better-quality inputs, via a rise of TFP, could compensate an ageing-induced slowing of economic growth. Here "better-quality" means more educated and older/more experienced workforces; and also...

A common problem with differences-in-differences (DD) estimates is the failure of the parallel-trend assumption. To cope with this, most authors include polynomial (linear, quadratic…) trends among the regressors, and estimate the treatment effect as a once-in-a-time trend shift. In practice...

Imagine an impoverished region that becomes eligible for a generous transfer programme (the treatment). Imagine difference-in-differences analysis (DD) — a before-and-after comparison of the income-level handicap — shows that the handicap has risen. Most observers would conclude to the...

Innovative workplace practices based on multi-tasking and ICT that have been diffusing in most OECD countries since the 1990s have strong consequences on working conditions. Available data show together with the emergence of new organizational forms like multi-tasking, the increase in the...

Recent developments in many industrialized countries have triggered a debate on whether monetary policy is effective when the nominal interest rate is close to zero. When the nominal interest rate hits its lower bound, the monetary authority is no longer in a position to pursue a policy of...

Consumer boycott campaigns against goods produced using child labour are becoming increasingly popular. Notwithstanding, there is no consensus on which are the e ects of such type of activism on child labour. If some agreement is to be found in the recent economic literature, it is that the...
