• Subsidy Phase-Out and Consumer Demand Dynamics: Evidence from the Battery Electric Vehicle Market in China AI翻译

  摘要：This article quantifies the impact of the battery electric vehicle subsidy program in China. We build a structural model of dynamic demand and Bertrand Nash supply to study price elasticity and changes in production costs. The model highlights four channels through which the subsidy program impacts the market: temporal elasticity, in response to a current price change; intertemporal elasticity, in response to a future price change; and multiplication effects through peer and learning by doing....
• Public Leaderboard Feedback in Sampling Competition: An Experimental Investigation AI翻译

  摘要：We investigate the role of performance feedback, in the form of a public leaderboard, in a sequential-sampling contest with costly observations. We show theoretically that for contests with a fixed ending date (i.e., finite horizon), providing public performance feedback may result in fewer expected observations and a lower expected value of the winning observation. We conduct a controlled laboratory experiment to test the theoretical predictions and find that the experimental results largely ...
• Identity Verification Standards in Welfare Programs: Experimental Evidence from India AI翻译

  摘要：We study the impact of reforms that introduced more stringent, biometric ID requirements into India's largest social protection program, using large-scale randomized and natural experiments. Corruption fell but with substantial costs to legitimate beneficiaries, 1.5-2 million of whom lost access to benefits at some point during the reforms. At the same time, adverse effects appear to have been driven primarily by decisions about the way the transition was managed, illustrating both the risks o...
• Do Export Support Programs Affect Prices, Quality, Markups, and Marginal Costs? Evidence From a Natural Policy Experiment AI翻译

  摘要：Firms success in international markets depends on their product's quality, prices, markups, and marginal cost. However, causally identified empirical evidence for the effect of trade policies that address nontariff barriers on these mechanisms is rare. To fill this gap, we exploit a quasinatural experiment in Denmark and examine the effects of an export support policy aimed at reducing nontariff barriers to trade. We find that export support raises firm-level exports within markets. However, e...
• Financing Municipal Water and Sanitation Services in Nairobi's Informal Settlements AI翻译

  摘要：We test two ways to improve revenue collection efficiency for water and sanitation utilities: (i) face-to-face engagement between utility staff and customers and (ii) contract enforcement for service disconnection due to nonpayment in the form of transparent and credible disconnection notices. Engagement has no effect, while enforcement significantly increases payment. We find no effect on access to water, perceptions of the utility, relationships between tenants and property owners, or on ten...
• 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
  作者单位：Max Planck Society
  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...
• ℓ 2-Relaxation: With Applications to Forecast Combination and Portfolio Analysis AI翻译

  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...

• Why Don't We Sleep Enough? A Field Experiment among College Students AI翻译

  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...
• Sibling Differences in Genetic Propensity for Education: How do Parents React? AI翻译

  摘要：We take advantage of recent advances in genomics to revisit a classic question in economics: how do parents respond to children's endowments and to sibling differences in endowments? We use an index based on DNA, which is fixed at conception and assigned randomly across siblings, as a proxy for educational endowments. We find that parents of nontwins display inequality aversion: given the absolute endowment level of one child, they invest less in him/her if his/her sibling has a lower genetic ...
