Worker-level panel data are used to analyse the separate employment effects of increases in the social security taxes paid by employers and increases in the minimum wage in Turkey between 2002 and 2005. Variation over time and among low-wage workers in the ratio of total labour costs to the...

We estimate the responses of gross labor earnings with respect to marginal and average netof-tax rates in France over the period 2003-2006. We exploit a series of reforms to theincome-tax and the payroll-tax schedules that affect individuals who earn less than twice theminimum wage. Our estimate...

We study the effects of revenue-neutral labor tax reforms in an imperfectly competitive domestic labor market under Nash wage bargaining and flexible outsourcing. A revenue-neutral increase in the wage tax progression will decrease the negotiated wage rate, increase domestic labor demand and...

This paper develops a dynamic general equilibrium model where employers may avoid making social security contributions by offering some workers "secondary contracts". When calibrated using aggregate tax revenue data, the model delivers estimates of secondary "off the books" employment that are...

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...

This paper revisits the standard model of labor supply under two additional assumptions: consumption requires time and some limited amount of work is enjoyable. Whereas introducing each assumption without the other one does not produce novel insights, combining them together does if the wage...

Cross-country differences of market hours in 17 OECD countries are mainly due to the hours of women, especially low-skilled women. This paper develops a model to account for the gender-skill differences in market hours across countries. The model explains a substantial fraction of the...

Assuming decreasing returns to education and the endogenous supply of qualified and non-qualified labour it is shown to be efficient to supplement a consumption tax with positive incentives for education. If the return from education is isoelastic and if the choice is between (i) subsidizing the...

Within an efficiency wage framework, we study the effects of two revenue-neutral tax reforms that change the progressivity of the labour tax system. A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the...

In a model in which agents differ in wages and preferences over labor time-consumption bundles, we study labor income tax schemes that alleviate poverty. To avoid conflict with individual well-being, we require redistribution to take place between agents on both sides of the poverty line...
