Recent studies have proposed causal machine learning (CML) methods to estimate conditional average treatment effects (CATEs). In this study, I investigate whether CML methods add value compared to conventional CATE estimators by re-evaluating Connecticut's Jobs First welfare experiment. This...

This paper develops a unified model of dual and unitary job holding based on a Stone-Geary utility function. The model incorporates both constrained and unconstrained labor supply. Panel data methods are adapted to accommodate unobserved heterogeneity and multinomial selection into 6 mutually...

This paper proposes a simple solution to the independence of irrelevant alternatives (IIA) problem in Choo and Siow (2006) model, overcoming what is probably the main limitation of this approach. The solution consists of assuming match-specific rather than choice-specific random preferences. The...

Welfare States do not insure citizens against the risk of premature death, i.e., the risk of having a short life. Using a dynamic OLG model with risky lifetime, this paper compares two insurance devices reducing well-being volatility due to the risk of early death: (i) an ante-mortem age-based...

Nozick's "utility monster" - a being who is more efficient than other persons at transforming resources into well-being - is often regarded as deeply impossible, on the ground of the incapacity of a single person to have a life that is better than a large number of other lives. In this article,...

The aim of this research is to build on a theory for explaining economic development in a (neoclassical) growth model with endogenous fertility. The economy is comprised of overlapping generations of rational and identical individuals and identical competitive firms producing with a...

A central policy issue in the battle against HIV in Sub-Saharan Africa (SSA) is whether and when high-prevalence countries might become fully autonomous in designing and implementing their own intervention policies aimed to control the disease. The aim of this research is twofold. First, it...

This paper examines the optimal direction of marginal income tax reform in the context of New Zealand, which recently reduced its top marginal income tax rate to one of the lowest in the OECD. A behavioural microsimulation model is used, in which social welfare functions are defined in terms of...

In the past years, work time in many industries has become increasingly flexible opening up a new channel for intertemporal substitution. To study this, we set up a two-period model with wage uncertainty. This extends the standard savings model by allowing a worker to allocate a fixed time...

We study the impact of income taxation on intergenerational income correlation. We estimate a life cycle dynastic model and conduct counterfactual analysis to observe the effects of various tax regimes. Compared to a no tax environment, a flat tax regime reduces the correlation only by one...
