摘要：In 2016, the city of Bogota doubled police patrols and intensified city services on high-crime streets. They did so based on a criminological consensus that such place-based programs not only decrease crime, but also have beneficial spillovers for nearby streets. To test this, we worked with Bogota to experiment on an unprecedented scale. We randomly assigned 1,919 streets to either 8 months of doubled police patrols, greater municipal services, both, or neither. Such scale brings econometric ...

摘要：We document three stylized facts on marriage and fertility patterns in East Asian societies: (i) their marriage rates are among the highest in the world, but their total fertility is the lowest; (ii) although they have the lowest total fertility, almost all married women have at least one child; and (iii) almost no single women have any children. As these societies have been influenced by Confucianism over millennia, marriage and fertility decisions are potentially shaped by two social norms: ...

摘要：I study the long-term consequences of an effective free school choice program that targeted disadvantaged students in Israel two decades ago. I show that the program led to significant gains in post-secondary education through increased enrolment in academic and teachers' colleges without any increase in enrolment in research universities. Free school choice also increased earnings at the adulthood of treated students. Male students had much larger improvements in college schooling and labor m...

摘要：We present the first evidence on the role of occupational choices and acquired skills for migrant selection. Combining novel data from a representative Mexican task survey with rich individual-level worker data, we find that Mexican migrants to the United States have higher manual skills and lower cognitive skills than nonmigrants. Results hold within narrowly defined region-industry-occupation cells and for all education levels. Consistent with a Roy/Borjas-type selection model, differential ...

摘要：Agents need to be motivated to develop ideas and to share information regarding their potential value. When the agents fail to agree on which alternative to implement, the principal needs to decide how to resolve the disagreement. When the agents' information is soft, favoring one of the agents in the case of disagreement is always optimal in the present setting. In contrast, if the information is hard, a balanced treatment of the agents is preferred to encourage competition. The reason for th...

摘要：We study countries' compliance with the targets pledged in international climate-change agreements and the impact of those agreements and specific climate laws and policies on greenhouse-gas emissions and economic outcomes. To do so, we compile and codify data on international agreements and measures enacted at the national and sub-national levels. We find that compliance with targets has been mixed. Still, countries that signed the Kyoto Protocol or the Copenhagen Accord experienced significa...

摘要：This paper studies the political determinants of inequalities in government interventions under majoritarian (MAJ) and proportional representation (PR) systems. We propose a probabilistic voting model of electoral competition with highly targetable government interventions and heterogeneous localities. We uncover a novel relative electoral sensitivity effect that affects government interventions only under MAJ systems. This effect tends to reduce inequality in government interventions under MA...

摘要：This paper estimates the causal effect of a historical midwifery policy experiment on maternal mortality, infant mortality, and stillbirth during the period of 1830-1894 in Sweden. Exploiting sharp changes or discontinuities across time and place in the availability of trained and licensed midwives as an exogenous source of variation, we find that a doubling of trained midwives led to a 20%-40% reduction in maternal mortality and a 20% increase in the uptake of midwife-assisted homebirths. The...

摘要：We develop a general framework to study source-dependent preferences in economic contexts. We behaviorally identify two key features. First, we drop the assumption of uniform uncertainty attitudes and allow for source-dependent attitudes. Second, we introduce subjective prices to compare outcomes across different sources. Our model evaluates profiles source-wise, by computing the source-dependent certainty equivalents; the latter are converted into the unit of account of a common source and th...
