Emotions are said to underlie moral decision-making. We detect intra-judge variation spanning three decades in 1.5 million judicial decisions driven by factors unrelated to case merits. U.S. immigration judges grant an additional 1.4 % points of asylum petitions–and U.S. district judges assign 0.6...

We set up a formal framework to characterize encompassing of nonparametric models through the distance. We contrast it to previous literature on the comparison of nonparametric regression models. We then develop testing procedures for the encompassing hypothesis that are fully nonparametric. Our...

Most low- and middle-income countries are characterised by a large informal sector, which implies that a substantial fraction of economic activity and livelihoods in these countries goes on completely unregulated. This has important implications for the behaviour of firms, workers, families, and...

We review the medico-economic literature assessing the economic value of diagnostic and prognostic tests, with a focus on innovative and, more specifically, companion tests. Our analysis begins with a summary of systematic reviews that provide a descriptive synthesis of existing findings rather...

We study collusion among firms against imperfectly monitored environmental regulation. Firms increase variable profits by violating regulation and reduce expected noncompliance penalties by violating jointly. We consider a case of three German automakers colluding to reduce the effectiveness of...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogeneous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

We present a lab-in-the-field experiment with employees of the Addis Ababa Water and Sanitation Authority to understand how to improve co-ordination and collaboration in their daily work. Participants play a series of public good games under different rules: a standard game, a game with a threshold...

I investigate high school tracking policies using a dynamic discrete choice model of study programs and unobserved effort. I estimate the model using data from Flanders (Belgium) and perform an ex ante evaluation of a policy that encourages underperforming students to switch to less academically...
