We study the optimal tax system when taxpayers earn different kinds of income by supplying different inputs. Imperfect substitution between inputs allows for general equilibrium effects. We consider any type of cross-base responses to tax changes such as income-shifting. Formalizing the tax...

A number of studies have examined the implications of preference interdependence. This paper models utility as depending on other people?s consumption levels and shows that welfare declines with inequality, equilibrium inequality is inefficient, and the optimal intervention leads to a more equal...

Incomplete information is a commitment device for time consistency problems. In the context of time consistent labor income taxation privacy can lead to a Pareto superior outcome and increases the effectiveness of public education as a second best policy.

This paper considers education investment and public education subsidies in closed and open economies with an extortionary government. The extortionary government in a closed economy has incentives to subsidize education in order to overcome a hold-up problem of time consistent taxation, similar...

This paper compares education investment in closed and open economies without government and with a benevolent government. The fact that the time consistency problem in taxation can make labor mobility beneficial even if governments are fully benevolent – which is known from other contexts –...

Restrictions on work hours are more important in countries with a large welfare state. We show that this empirical observation is consistent with the strategic effects of such restrictions in a welfare state in the context of optimal direct taxation in the tradition of Mirrlees (1971). Our...

The paper examines the possible effects of introducing a large-scale welfare reform in Sweden, namely, the introduction of comprehensive welfare accounts. Under this policy, individuals make mandatory contributions to accounts, which they can top up with voluntary contributions. In return,...

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment, and the political difficulties in implementing more extensive reform programs. We argue that the heart of...

By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...
