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...

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 analyzes the effects of introducing a graduated minimum wage in a model with optimal income taxation in which a government seeks to maximize social welfare. It shows that the optimal graduated minimum wage increases social welfare by increasing the low productivity workers'...

The case for NIT+FT in Europe. An empirical optimal tWe present an exercise in empirical optimal taxation for European countries from three areas: Southern, Central and Northern Europe. For each country, we estimate a microeconometric model of labour supply for both couples and singles. A...

The prolonged career break around childbirth is one of the reasons behind large motherhood penalties in terms of pay and employment opportunities. We aim to understand what is driving the duration of career break in Italy, where it often remains longer than the five-month obligatory maternity...

In this paper, we use EUROMOD, the tax-benefit microsimulation model of the European Union, to investigate the impact of marriage-related tax-benefit instruments on the labour supply of married couples. For each married partner, we estimate their individual marginal effective tax rate and net...

This paper analyzes how intrahousehold bargaining power impacts labor supply, for seventeen European countries. To that end, we estimate a collective model using the European Union Statistics on Income and Living Conditions for the period 2004-2019, and we study the validity of several potential...

This paper utilizes the 1968-2019 survey waves of the Panel Study of Income Dynamics to analyze the added worker effect for wives of husbands who lose their job through no fault of their own. Specifically, we focus on the potential changes to the added worker effect over time. For wives who were...

We study the effect of childbirth and its timing on female labour market outcomes in Italy. The impact on yearly labour earnings and participation is traced up to 21 years since school completion by estimating a factor analytic model with dynamic selection into treatments. We find that...

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...
