We use surveys, laboratory experiments and administrative data to study how heterogeneity in the perceived immorality of work and in workers' aversion to acting immorally impact labor market outcomes. Immoral work is associated with higher wages, both in administrative data and in causal...

This paper examines the effects of universal daycare on mothers' labor force participation, full-time employment, and earnings over their working lifetime. I exploit differential access to daycare caused by a roll-out of daycare centers across Denmark in combination with rich administrative...

We model the interaction between the marriage market and the intrahousehold allocation of resources. We do this within a setting that accounts for both economic gains to marriage (through public consumption) and unobserved non-material match quality, without relying on the transferable utility...

Whether monetary incentives to change behavior work and how they should be structured are fundamental economic questions. We overcome typical data limitations in a large-scale field experiment on vaccination (N = 5, 324) with a unique combination of administrative and survey data. We find that...

We examine the impact of a carbon tax on consumer choices via a large-scale online randomized controlled trial. Higher taxes generally reduce the demand for high-carbon goods. Compared to an import tax, a carbon tax reduces demand when the tax is zero (i.e., announced but not levied) but shows...

While physicians are crucial to patient outcomes, what determines physician behavior and decision making remains to be understood. In this paper, we study how physicians' family characteristics influence physicians' behavior and patient health outcomes. Using administrative data from Denmark and...

I investigate what affects foreign students' decision to stay and work in the host country after completion of higher education. Specifically I ask whether the network of native peers at university affect the probability that foreign students in Denmark stay in the country and find employment...

Peer evaluation tournaments are common in academia, the arts, and corporate environments. They make use of the expert knowledge that academics or team members have in assessing their peers' performance. However, rampant opportunities for cheating may throw a wrench in the process unless,...

This paper explores the relationship between decision-making speed and the effectiveness of two nudges - carbon footprint labelling and menu repositioning - aimed at encouraging climate-friendly food choices. Building on Kahneman's dual-process theory of decision-making, we examine whether these...

Using administrative data on wealth, firm ownership structure, and migration in Sweden and Denmark, we document international migration patterns among the very wealthy, their impact on the economy, and how they respond to wealth taxation. We show that more than 20% of taxpayers liable to pay...
