题目:Education and the Meritocratic Recruitment of Bureaucrats (基于贤能的官员选拔体制和人力资本投资)


Do merit-based recruitment policies create incentives for human capital investment? We provide evidence from historical Taiwan, where elite bureaucrats were recruited through a civil service examination. Quotas for successful candidates were set based on the 1948 populations of individuals' native provinces in mainland China, resulting in highly preferential quotas for certain groups. This system was abruptly replaced in 1962 by a uniform admissions policy. We leverage this variation to study the impacts of differential access to elite bureaucratic posts. We find that the additional incentives created by preferential quotas increased human capital accumulation and resulted in better long-run economic outcomes.

题目:Social Stigma as a Barrier to HIV Testing: Evidence from a Randomized Experiment in Mozambique(社会污名化与HIV检测:来自莫桑比克的实验证据)


Public health experts have seen the stigma as a leading barrier affecting the delivery of HIV-related health care. By using a field experiment in Mozambique, this study identifies the role of stigma concerns in hindering HIV testing and quantifies the stigma barrier. To obtain local measures of the HIV stigma environment in the study sites, we conducted a baseline survey one year before the experiment. Experiment participants with excessive concerns, defined as overestimating the stigma in their communities, were randomly assigned an intervention to relieve stigma concerns. The intervention, which drew upon findings from the baseline survey, was designed to reveal the correct degree of stigma that a participant had overestimated. Analyses show that this intervention raised the HIV test uptake rate by 7.7 percentage points (or by 37 percent) from 20.7 percent under the control condition. To quantify the intervention effect, I introduced testing coupons of different values to estimate the demand curve for an HIV test. The concern-relieving intervention raised an individual’s willingness-to-pay for an HIV test by $1.30, or more than half of the daily cost-of-living in the study population.
