| Summary/Abstract |
Infectious diseases put health of millions at risk and induce large socioeconomic costs each year. However, the long-term effects of exposure to infectious diseases on the elderly have received minimal attention. Using data from the Chinese Longitudinal Healthy Longevity Survey, this study adopts a differences-in-differences strategy to evaluate the long-term effects of epidemic exposure on old-age mortality. We find that intense exposure to the severe acute respiratory syndrome (SARS) epidemic led to an increase in old-age mortality after the SARS outbreak. We provide some suggestive evidence that exposure to SARS increased psychological stress and limitations in physical activities among old people.

| Summary/Abstract |
Grade retention is a common practice in many countries despite the fact that the evidence for its influence on child development is mixed. In 2006, China introduced a new rule that explicitly prohibited grade repetition during the compulsory education period. Exploiting the staggered introduction of this policy across provinces and applying a flexible difference-in-differences strategy, we analyze the causal effects of the reform on various student outcomes, including school completion and cognitive skills, mental health and self-confidence in early adulthood. The results indicate that automatic grade promotion hurts students' educational development, especially for boys and for children with less-educated mothers. On the other hand, however, the reform indeed improved mental health, as noted by the proponents of social promotion. More importantly, we find that all the policy impacts are concentrated solely among students exposed to the reform in an early grade, particularly 1st-3rd grade. The results further indicate that removing the “threat” of grade retention results in a decrease in study time in the long run, which we interpret as a potential mechanism.

| Summary/Abstract |
This article examines how violence against citizens affects their political attitudes and behavior in the long run, and how those effects vary over time. We construct and analyze a novel dataset on the victims of Taiwan's February 28 Incident, in 1947, with survey data spanning 1990 to 2017. Our empirical analysis shows that cohorts having directly or indirectly experienced the Incident are less likely to support the Kuomintang Party (KMT), the former authoritarian ruling party responsible for the Incident. They tend to disagree with the key conventional policy stand of the KMT (unification with mainland China), are more likely to self-identify as Taiwanese, and are less likely to vote for KMT presidential candidates. Taiwan's residents who were born in towns with larger number of casualties during the Incident are more likely to reject unification. Finally, the effects are found to vary over the period following democratization.
