• Too Lucky to Be True: Fairness Views under the Shadow of Cheating AI翻译
  作者：Bortolotti, Stefania; Soraperra, Ivan; Sutter, Matthias; Zoller, Claudia

  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...
• Technology Training, Buyer-Supplier Relationship, and Quality Upgrading in an Agricultural Supply Chain AI翻译

  摘要：This paper examines the impacts of technology training and buyer-supplier relationship on technology adoption and quality upgrading. We randomly varied subjects of each training group across farmer-exporter clusters-farmers, exporters, both, or none-and provided training on Good Agricultural Practices (GAP). We find that training farmers enhances technology adoption and quality upgrading. Yet, the effects are much stronger when farmers and exporters are trained together. We document a plausibl...

  摘要：Does social distancing harm innovation? We estimate the effect of nonpharmaceutical interventions (NPIs)-policies that restrict interactions in an attempt to slow the spread of disease-on local invention. We construct a panel of issued patents and NPIs adopted by 50 large U.S. cities during the 1918 flu pandemic. Difference-in-differences estimates show that cities adopting longer NPIs did not experience a decline in patenting during the pandemic relative to short-NPI cities, and they recorded...

• Low-Quality Seeds, Labor Supply, and Economic Returns: Experimental Evidence from Tanzania AI翻译

  摘要：Low productivity in agriculture is a major cause of povertyand food insecurity in Africa. One explanation for low productivity is thewidespread presence of low-quality inputs on local markets (lemon tech-nologies), which causes uncertainty among farmers and erodes incentivesfor adoption. We report the results from a field experiment in Tanzania tostudy the impact of improved maize seeds in a context where we exoge-nously vary seed quality and uncertainty about seed type. The analysis isat the ...
• Influence-Seeking in US Corporate Elites' Campaign Contribution Behavior AI翻译

  摘要：I leverage a new panel on the contributions to members of the U.S. Congress (MCs) from 401,557 corporate leaders of 14,807 U.S. corporations over 1999-2018 to show that U.S. corporate elites use contributions to political campaigns as a tool of political influence. Donations increase by 11% when a politician is assigned to a committee dealing with policy issues relevant to a corporate leader's company. The effect is driven by donations to MCs with the greatest power in the committees. I estima...
• What Matters for Electrification? Evidence from 70 Years of US Home Heating Choices AI翻译
  作者：Davis, Lucas W.
  作者单位：University of California System; University of California Berkeley
  摘要：The percentage of U.S. homes heated with electricity has increased steadily from 1% in 1950 to 40% in 2020. Energy prices, geography, climate, housing characteristics, and income are shown to explain 90% of the increase, with energy prices by far the most important factor. The paper then estimates the cost of an electrification mandate for new homes. Households in warm states tend to prefer electricity anyway, so would be made worse off by less than $350 annually on average. Households in cold...
• Factorial Designs, Model Selection, and (Incorrect) Inference in Randomized Experiments AI翻译

  摘要：Factorial designs are widely used to study multiple treatments in one experiment. Although t-tests using a fully saturated long model provide valid inferences, short model t-tests (that ignore interactions) yield higher power if interactions are zero, but incorrect inferences otherwise. Of 27 factorial experiments published in top-five journals (2007-2017), nineteen use the short model. After including interactions, more than half of their results lose significance. Based on recent econometric...
• BIDDING ON PRICE AND QUALITY: AN EXPERIMENT ON THE COMPLEXITY OF SCORING RULE AUCTIONS AI翻译

  摘要：We experimentally study procurement auctions when both quality and price matter. We compare two treatments where sellers compete on one dimension only (price or quality), with three treatments where sellers submit a price-quality bid and the winner is determined by a scoring rule that combines the two offers. We find that, in the scoring rule treatments, efficiency and buyer's utility are lower than predicted. Estimates from a Quantal Response Equilibrium model suggest that increasing the dime...
• Short and Simple Confidence Intervals When the Directions of Some Effects Are Known AI翻译

  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...
