摘要：Income inequalities within societies are often associated with evidence that the rich are more likely to behave unethically and evade more taxes. We study how fairness views and preferences for redistribution are affected when cheating may, but need not, be the cause of income inequalities. In our experiment, we let third parties redistribute income between a rich and a poor stakeholder. In one treatment, income inequality was due only to luck, whereas in two others rich stakeholders might hav...

摘要：We propose & ell;( 2)-relaxation, which is a novel convex optimization problem, to tackle a forecast combination with many forecasts or a minimum variance portfolio with many assets. & ell;( 2)-relaxation minimizes the squared Euclidean norm of the weight vector subject to a set of relaxed linear inequalities to balance the bias and variance. It delivers optimality with approximately equal within-group weights when latent block equicorrelation patterns dominate the high-dimensional sample vari...

摘要：This study investigates the mechanisms affecting sleep choice and explores whether commitment devices and monetary incentives can be used to promote healthier sleep habits. To this end, we conducted a field experiment with college students, providing them incentives to sleep and collecting data from wearable activity trackers, surveys, and time-use diaries. Monetary incentives were effective in increasing sleep duration with some evidence of persistence after the incentive was removed. We unco...

摘要：We provide evidence on the mechanisms linking resource-related income shocks to conflict, focusing on illegal crops. We hypothesize that the degree of group competition over resources and the extent of law enforcement explain whether opportunity cost or contest effects dominate. Combining temporal variation in international drug prices with spatial variation in the suitability to produce opium, we show that higher prices increase household living standards and reduce conflict in Afghanistan. A...

摘要：The paper combines extreme value theory for the smallest and largest k observations for some given k > 1 with a normal approximation for the average of the remaining observations to construct a more robust alternative to the usual t-test. The new test is found to control size much more successfully in small samples compared to existing methods. This holds for the canonical inference for the mean problem based on an i.i.d. sample, but also when comparing two population means and when conducting...

摘要：We examine the use of instrumental variable (IV) methods to measure the effect of a ceteris paribus change in an endogenous variable on an ordered outcome. Specifically, we use these methods to investigate the effect of neighborhood characteristics on subjective well-being (SWB) among participants in the Moving to Opportunity (MTO) housing voucher experiment. We find that the estimated positive effect of a decrease in neighborhood poverty on SWB is sensitive to the specification of the first-s...

摘要：This paper identifies productivity gains from trade by studyingthe manipulation behavior of firms in response to regulatory policies oninternational trade in China. Bunching estimates show that participationin international trade increases firm productivity. The productivity gainsincrease over time, indicating dynamic learning from trading. Further exploration shows no effects on R&D investment, product rationalization,and markup. Young firms and nonstate-owned firms (non-SOEs) gain morefrom p...

摘要：I compare the impact of local tax revenue and royalties from the extraction of natural resources on governance in Colombian municipalities, leveraging plausibly exogenous variation from cadastral updates and fluctuations in the world price of oil. Higher tax revenue has a larger effect on local public goods in the areas of education, health, and water than a same-sized increase in oil royalties, despite earmarking of royalties for spending in these areas. Higher tax revenue also reduces the pr...

摘要：We introduce adaptive confidence intervals on a parameter of interest in the presence of nuisance parameters, such as coefficients on control variables, with known signs. Our confidence intervals are trivial to compute and can provide significant length reductions relative to standard ones when the nuisance parameters are small. At the same time, they entail minimal length increases at any parameter values. We apply our confidence intervals to the linear regression model, prove their uniform v...
