摘要：We investigate the impact of peer interaction on the quality of fi-nancial decision making in a laboratory experiment. Face-to-face commu-nication with a randomly assigned peer significantly improves the qualityof subsequent private decisions even though simple mimicry would havethe opposite effect. We present evidence that the mechanism involves gen-eral conceptual learning (because the benefits of communication extend topreviously unseen tasks), and that the most effective learning relations...

摘要：This paper uses new data on the removal of local, sector-specificbarriers to firm entry across 1,800 municipalities in Peru to estimate theimpact on firm productivity and markups. New legislation in 2013 strength-ened the national competition authority's mandate to enforce the elimi-nation of local entry barriers, providing a quasi-experimental setting toidentify the impact of competition on productivity within the controlledinstitutional environment of a single country. We find that the elimi...

摘要：We report the results of two laboratory experiments and a repre-sentative survey that investigate how default effects are shaped by informa-tion asymmetries and strategic incentives. We document that defaults aremore informative when the interests of default setters and decision makersare more closely aligned. Decision makers' propensity to accept defaultsdepends, both, on the alignment of interests and the quality of their infor-mation. In a second experiment, we demonstrate that decision mak...

摘要：We examine the impact of government funding for R&D-anddefense-related R&D in particular-on privately conducted R&D and itsultimate effect on productivity growth. We estimate longitudinal modelsthat relate privately funded R&D to lagged government-funded R&D usingindustry-country level data from OECD countries and firm level data fromFrance. To deal with the potentially endogenous allocation of governmentR&D funds, we use changes in predicted defense R&D as an instrumentalvariable. In many OEC...

摘要：We provide a method to track the active prevalence of COVID-19 in real time, correcting for time-varying sample selection in symptom-based testing data and incomplete tracking of recovered cases and fatalities. Our method only requires publicly available data on positive testing rates in combination with one parameter, which we estimate based on a representative randomized sample of nearly 10,000 individuals tested in Utah in May and June 2020. We validate our method using external studies in ...

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：Export promotion at the extensive margin is a key concern ofgovernments. We develop measures of how far firms in origin sectors arefrom break-even entry in destination markets. The measure is based on Al-most Ideal gravity featuring heterogeneous price and income elasticities.Tobit estimation of 2006 trade flows for 75 countries and 25 sectors gener-ates latent trade bias (LTB)-the latent (projected) trade share of nonpart-ners minus the as-if-frictionless trade share. Explained LTB variance d...

摘要：We analyze the impact of Covid-19 on productivity using datafrom an innovative monthly firm survey that asks for quantitative impactsof Covid-19 on inputs and outputs. We find thattotal factor productiv-ity (TFP) fell by up to 6% during 2020-2021. The overall impact com-bined large reductions in 'within-firm' productivity, with offsetting posi-tive 'between-firm' effects as less productive sectors, and less productive firms within them, contracted. Despite these large pandemic effects, firms'p...
