We develop a methodology to sign output distortions in the random participation framework. We apply our method to monopoly nonlinear pricing problem, to the regulatory monopoly problem and mainly to the optimal income tax problem. In the latter framework, individuals are heterogeneous across two...

This paper examines whether myopia (misperception of the long-term care (LTC) risk) and private insurance market loading costs can justify social LTC insurance and/or the subsidization of private insurance. We use a two-period model wherein individuals differ in three unobservable...

Addressing extensive labour supply responses, the literature has established a case for larger transfers to the working poor than to even poorer non-working people. This paper casts new light on this result. I argue that the result hinges crucially on the labour supply responses of people in...

This paper studies the implications of introducing child care in the human capital production function when assessing the effects of labor income taxation on growth. We develop an OLG model where formal schooling and child care enter the human capital production function as complements and we...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient not to distort the choice of education. In general this implies distorting the saving decision. Hence a strict order of policy priority is derived. Efficient tax policy...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient to deviate from Ramsey's Rule and to distort qualified labour less than nonqualified labour. The result holds for arbitrary utility and learning functions. Efficient...

We document the time-series of employment rates and hours worked per employed by married couples in the US and seven European countries (Belgium, France, Germany, Italy, the Netherlands, Portugal, and the UK) from the early 1980s through 2016. Relying on a model of joint household labor supply...

Do minimum wages reduce in-work-poverty and wage inequality? Or can alternative policies do better? We evaluate theses issues for the exemplary case of Germany that suffers from high unemployment among low-skilled workers and rising wage dispersion at the bottom of the wage distribution. We...

Hiring subsidies are widely used to create (stable) employment for the long-term unemployed. This paper exploits the abolition of a hiring subsidy targeted at long-term unemployed jobseekers over 45 years of age in Belgium to evaluate its effectiveness in the short and medium run. Based on a...
