We estimate the responses of gross labor income with respect to marginal and average net-of-tax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and payroll-tax schedules affecting individuals who earn less than twice the minimum wage. Our estimate for...

This paper presents the properties of optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction between second earner wage differences, variation in the price of child care and...

Analyzing a homogenous household setting with endogenous fertility and endogenous labor supply, we demonstrate that moving from joint taxation to individual taxation and adapting child benefits so as to keep fertility constant entails a Pareto improvement. The change is associated with an...

This paper presents an approach for the estimation of welfare effects of tax policy changes under heterogeneity in consumer preferences. The approach is applied to evaluate the welfare effects of current tax advantages for electric vehicles supplied as fringe benefits by employers. Drawing on...

The 2008 financial crisis is the worst economic crisis since the Great Depression of 1929. It has been characterised by a housing bubble in a context of rapid credit expansion, high risk-taking and exacerbated financial leverage, ending into deleveraging and credit crunch when the bubble burst....

In the United States, charitable contributions can be deducted from taxable income making the price of giving inversely related to the marginal tax rate. The existing literature documents that charitable giving is very responsive to tax subsidies, but often ignores the spillover effects of such...

The main research question of the project is summarized as: What are the macroeconomic and distributional consequences of fiscal devaluation for a selection of countries and the EU as a whole? The selected countries are France, Italy, Spain and Austria. The project aims to perform four tasks: 1....

This paper extends the Mirrlees (1971) model of optimal non-linear income taxation with a monitoring technology that allows the government to verify labor effort at a positive, but non-infinite cost. Monitored individuals receive a penalty, which increases if individuals earn a lower income...

Given that young children are under the control of their parents, if the government has an interest in either the welfare or the productivity of the former, it has no option but to act through the latter. Parents are, in the ordinary sense of the word, the government’s agents. They are agents...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...
