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....

We examine whether financial incentives affect fertility and family planning. We use a reform reducing child benefits paid to larger families together with Danish longitudinal register data on the universe of legal abortions and birth control pill purchases to address this question. We find that...

We investigate long-run earnings responses to taxes in the presence of dynamic returns to effort. First, we develop a theoretical model of earnings determination with dynamic returns to effort. In this model, earnings responses are delayed and mediated by job switches. Second, using...

We study how individuals update their beliefs in the presence of competing datagenerating processes, or models, that could explain observed data. Through experiments, we identify the weights participants assign to different models and find that the most common updating rule gives full weight to...

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...

Standard economic theory assumes that consumers ignore the externalities they create, such as emissions from burning fossil fuels and generating waste. In an incentivized study (N = 3, 718), we find that most people forgo substantial gains to avoid imposing negative externalities on others....

Investors' return expectations are pivotal in stock markets, but the reasoning behind these expectations remains a black box for economists. This paper sheds light on economic agents' mental models - their subjective understanding - of the stock market, drawing on surveys with the US general...

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...

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,...

Cryptocurrencies pose substantial challenges to tax enforcement due to their anonymous and decentralized properties, undermining conventional regulatory practices. We study the impact of an ambitious new enforcement initiative aimed at addressing these challenges: domestic third-party reporting...
