摘要：We examine how the evaluation of research studies in economics depends on whether a study yielded a null result. Studies with null results are perceived to be less publishable, of lower quality, less important and less precisely estimated than studies with large and statistically significant results, even when holding constant all other study features, including the sample size and the precision of the estimates. The null result penalty is of similar magnitude among PhD students and journal ed...

摘要：Academia, and economics in particular, faces increased scrutiny because of gender imbalance. This paper studies the job market for entry-level faculty positions. We employ machine learning methods to analyse gendered patterns in the text of 12,000 reference letters written in support of over 3,700 candidates. Using both supervised and unsupervised techniques, we document widespread differences in the attributes emphasised. Women are systematically more likely to be described using 'grindstone'...

摘要：'Right to Buy', a large-scale natural experiment whereby incumbent tenants in public housing could buy properties at heavily subsidised prices, increased the United Kingdom homeownership rate by over 10 percentage points between its 1980 introduction and the 1990s. This paper studies the impact of this reform on crime by leveraging exogenous variation in eligibility for the policy. Results show that Right to Buy generated significant property crime reductions. Behavioural changes of incumbent ...

摘要：This article examines pricing in pharmaceutical markets where branded products face competition from generics. After providing evidence for brand premia and switching costs using prescription-level and matched socioeconomic data for the entire Swedish population, I estimate a dynamic oligopoly model and evaluate counterfactual policies that reduce the impact of frictions on pricing. Lengthening the procurement period reduces the impact of switching costs on prices. The policy increases prices ...

摘要：We investigate how information about recipients' characteristics affects donors' giving as opposed to when no information is available. In a rational model in which information causes a donor to update their assessment of the recipient's deservingness, we introduce the idea that altruism can be 'persuadable' ('dissuadable') by information about positive (negative) characteristics. We report data from three experiments in which donors are provided information regarding three recipient character...

摘要：Partitioned pricing is a pricing practice that divides the price of a product into a base price and one or more mandatory surcharges. This paper develops a theory of partitioned pricing using a duopoly model where the owner of each firm determines the surcharge, but delegates the setting of the base price to a manager. In equilibrium, both firms choose partitioned pricing over the conventional all-inclusive pricing. Moreover, partitioned pricing leads to higher full prices and larger profits t...

摘要：Managing student behaviour is integral to the education production process. We study the trade-offs of school suspension policies by modelling and estimating how changes in school suspension policies causally impact student performance and teacher turnover. Our results indicate that the reduction in suspension rates in the Los Angeles Unified School District decreased math and English test scores, decreased grade point averages and increased absences. Teacher turnover also increased, particula...

摘要：This paper studies the relationship between pre-college skills and gender differences in STEM majors. I use longitudinal data to estimate a generalised Roy model of initial major choices and subsequent graduation outcomes. I recover students' latent math ability, non-cognitive skills and math self-efficacy. High-math-ability women have lower math self-efficacy than men. Mathematical ability and self-efficacy shape the likelihood of STEM enrolment. A lack of math self-efficacy drives women's dr...

摘要：This paper examines the causal effect of political legitimacy on stability, using the historical case of Imperial China. Chinese rulers ascribed their legitimacy to a heavenly mandate. Calamities like earthquakes were considered to be a sign of weakened approval, making quakes a proxy for a negative legitimacy shock. I use quake-induced minor shaking (i.e., strong enough to be felt, but too weak to cause material damage) to demonstrate that legitimacy shocks cause more conflicts. I examine whe...

摘要：Trusting behaviour is a cornerstone of cooperation and, hence, economic performance, not least in poorer communities where economic transactions often rely on informal agreements. But trusting behaviour is potentially costly since the counterpart may decide to defect. In this study, we investigate whether food scarcity influences the level of trusting behaviour in rural Tanzania by leveraging quasi-experimental variation in food supply induced by the harvest. Through a lab-in-the-field experim...
