摘要：A model is presented where the welfare of contributors to a public good can increase when they face an adversary who ex post sabotages their efforts. It is a best response for the adversary to maximally sabotage the smallest effort, thus increasing a defector's marginal product of effort. This creates a kink in the individual contributor's payoff function around the equilibrium effort, which can lock contributors into exerting high effort. For a sufficiently large degree of complementarity bet...

摘要：During the COVID-19 pandemic, traditional (offline) chess tournaments were prohibited and instead held online. We exploit this unique setting to assess the impact of remote work policies on the cognitive performance of individuals. Using the artificial intelligence embodied in a powerful chess engine to assess the quality of chess moves and associated errors, we find a statistically and economically significant decrease in performance when an individual competes remotely versus offline in a fa...

摘要：Are individuals of higher socio-economic status less ethical than those of lower status? Highly popularised research findings claim that this is the case. This paper provides evidence against this claim, based on data from two large survey experiments with more than 11,000 participants. We prime social status in two heterogeneous samples of the German population and then elicit ethical behaviour in an incentivised experimental task. Thus, our data allows us to study both correlation (using dem...

摘要：We develop a model of international trade with heterogeneous firms and monopsonistically competitive labour markets. We show that due to monopsonistic competition our model makes sharply different predictions about the effects of the export of goods and the offshoring of tasks. Trade in goods is unambiguously welfare increasing as domestic resources are reallocated to large firms with high productivity and firms with low productivities exit the market thereby reducing the monopsony distortion ...

摘要：Patience and risk-taking-two preference components that steer intertemporal decision-making-are fundamental to human capital investment decisions. To understand how they contribute to international skill differences, we combine Programme for International Student Assessment tests with the Global Preference Survey. We find that opposing effects of patience (positive) and risk-taking (negative) together account for two-thirds of the cross-country variation in student skills. In an identification...

摘要：We study the role of perceived trade-offs between human lives and economic benefits in shaping policy views. In an online experiment with a representative sample from the United States conducted during the early Covid-19 pandemic, we provide randomised information on the medium-run costs of restricting economic activity to mitigate infections. A one standard deviation lower perceived economic cost of lockdowns increases support by about twice as much as having a Covid at-risk condition, and by...

摘要：We explore the impact of wage offers on job applications, testing implications of the directed search model and trying to distinguish it from random search. We use a field experiment conducted on a Chinese job board, with real jobs for which we randomly vary the wage offers across three ranges. We find that higher wage offers raise application rates overall, which is consistent with directed search, but can also arise with random search. We also find that higher wage offers raise application r...

摘要：This paper examines the effect of campaign appearances in the context of the one-sided nationwide tour by William J. Bryan, the Democratic US presidential candidate in 1896. During this electoral campaign, Bryan undertook an unprecedented whistle-stop train tour, while the Republican candidate followed a front-porch campaign. To identify the causal effect of campaign speeches, we exploit several estimation strategies, including a within-county difference-in-differences design and a neighbour-p...

摘要：We develop a novel way of identifying the liquidity and moral hazard effects of unemployment insurance exclusively from how job-finding rates respond to unemployment benefits that vary over an unemployment spell. We derive a sufficient statistics formula for the dynamically optimal level of unemployment benefits based on these two effects. Using a regression kink design (RKD) that simultaneously exploits two kinks in the schedule of unemployment benefits, we apply our method to Spain for the y...

摘要：Can strengthening intellectual property protection for producers of one good affect innovation in other related goods? To answer this question, we exploit a unique policy experiment in the interwar military aircraft industry. Airframe designs had little intellectual property protection before 1926, but changes passed by Congress in 1926 provided airframe manufacturers with enhanced property rights over new designs. We show that granting property rights to airframe producers increased innovatio...
