We study the effect of having high socioeconomic status (SES) peers on pupils' wellbeing, absence rate, and academic performance in elementary school. We compare pupils in the same school who started school in different years and, consequently, were exposed to different shares of high-SES peers....

Does the presence of a partner affect individuals' propensity to participate in the stock market? In this paper, we estimate the effect of cohabiting with a partner on stock market participation using rich administrative data from Denmark. It is a well-known puzzle that few people participate in...

Who commits crime? Theoretically, risk-tolerant and impatient people are more likely to commit crime because they care less about the risks of apprehension and punishment. By linking experimental data on risk tolerance and impatience of young men to administrative crime records, we find...

Denmark is one of the richest countries in the world and achieves this in combination with low inequality, low unemployment, and high income security. This performance is often attributed to the Danish labor market model characterized by what has become known as flexicurity. This essay describes...

The existing literature suggests that the concern for economic efficiency calls for individual taxation of married couples with a higher rate on the primary earner. This paper reconsiders the choice of tax unit in the Becker model of household production, which includes previous analyses as...

A central finding of the modern labor market literature is that labor supply responses tend to be concentrated along the extensive margin (labor force participation) rather than the intensive margin (hours of work). Yet, the literature on the marginal cost of public funds (MCF) focuses solely on...

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...

There currently exist two competing approaches in the literature on the optimal provision of public goods. The standard approach highlights the importance of distortionary taxation and distributional concerns. The new approach neutralizes distributional concerns by adjusting the non-linear...

This paper estimates the welfare and distributional impact of two types of welfare reform in the 15 (pre-enlargement) member countries of the European Union. The reforms are revenue neutral and financed by an overall and uniform increase in marginal tax rates on earnings. The first reform...

This paper presents an evaluation of the tax-transfer treatment of married couples in 15 EU countries using the EUROMOD microsimulation model. First, we show that many tax-transfer schemes in Europe feature negative jointness defined as a situation where the tax rate on one person depends...
