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

This paper assumes the standard optimal income tax model of Mirrlees (Review of Economic Studies, 1971). It gives fairly mild conditions under which the optimal nonlinear labor income tax profile derived under maximin has higher marginal tax rates than the ones derived with welfarist criteria...

This paper examines optimal redistribution in a model with high and low-skilled individuals with heterogeneous tastes for labor, that either work or not. With such double heterogeneity, traditional Welfarist criteria including Utilitarianism fail to take the compensation-responsibility trade-off...

Two-sided platform firms serve distinct customer groups that are connected through interdependent demand, and include major businesses such as the media industry, banking, and the software industry. A well known result of tax incidence is that consumers of a more heavily taxed good pay a higher...

In this paper we analyse how fairness considerations, in particular considerations of just income distribution, affect whether or not people find tax evasion justifiable and their willingness to evade taxes. Using data from the Norwegian “Hidden Labour Market Survey” we show that individuals...

This paper studies the optimal income redistribution and monitoring when disability benefits are intended for disabled people but where some able agents with high distastes for work mimic them (type II errors). Labor supply responses are at the extensive margin and endogenous takeup costs burden...

This article explores the use of workfare as part of an optimal tax mix when labor supply responses are along the extensive margin. Particular attention is paid to the interaction between workfare and an earned income tax credit, two policies that are designed to provide additional incentives...

Using Norwegian individual register data of young workers, from the period 1986-2008, we analyze whether there are large and persistent negative relationships between unemployment and the risk of repeated unemployment and being out of labor force. A nearest-neighbor propensity score matching...

A model for matched data with two types of unobserved heterogeneity is considered one related to the observation unit, the other to units to which the observation units are matched. One or both of the unobserved components are assumed to be random. This mixed model allows identifi cation of the...

There is relatively little research on peer effects in teenage motherhood despite the fact that peer effects, and in particular social interaction within the family, are likely to be important. We estimate the impact of an elder sister’s teenage fertility on the teenage childbearing of their...
