This paper focuses on the study of the effects on social welfare generated by the scheme of joint taxation of the Spanish Personal Income Tax (PIT), whose peculiarity linked to its condition of optionality, allows the minimization of households´ tax bill. Different scenarios are simulated using...

Tax reform proposals affect individual welfares in ways which strongly depend on the nature of specialization in household production and the pattern of trade within households. Variation in the degree of specialization in domestic production across households strongly influences the impacts on...

This paper examines the response of husbands' and wives' earnings to a tax reform in which husbands' and wives' tax rates changed independently, allowing me to examine the effect of both spouses' incentives on each spouse's behavior. I compare the results to those of more simplified econometric...

The UK Government enacted simplification of its tax credit system in 2003. An inter- esting consequence of the reform is that tax credit payments were split between partners in couples, causing a rare wallet to purse transfer. This paper presents evidence on the effects of the reform on family...

This paper studies the optimal non linear income tax of couples. We build a general unitary model of labor supply and allow multidimensional heterogeneity in a discrete type framework. We concentrate our analysis on the resulting intra-family labor allocation of labor supplies and show that this...

This paper explores the optimal income tax treatment of couples. Each couple is modelled as a single agent supplying labor along two dimensions: primary-earner and secondary-earner labor supply. We consider fully general nonlinear income tax schedules which creates a multi-dimensional screening...

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 applies the theory of relational contracts to make precise the idea that because households are engaged in a repeated non-cooperative game, Pareto efficient outcomes can be supported by self interest, given the specific pattern of specialisation and exchange which exists in the...

This paper analyses optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. It models the interaction between wage rates and variation in child care prices and productivities as determinants of across-household heterogeneity in second...

This paper studies the design of couples' income taxation. Consumption and labor supply decisions within the couple are made by maximizing a weighted sum of the spouses’ utilities; bargaining weights are given but specific to each couple. The information structure and labor supply decisions...
