JMP专栏：UC-San Diego 第5期
为什么会有这个专栏？
有人曾问退休后的萨缪尔森：“能不能请您谈谈目前经济学研究的前沿是什么?”
萨翁答:“我不知道前沿在哪儿，如果我知道，我早就在哪儿了。这问题该去问我们的博士生。”
于是，我和小伙伴们在2023年底开启了一项“宏大”的计划，搜集整理美国经济系排名最靠前的10所高校博士生们的工作市场论文，这些论文一定程度上代表了经济学界的学术前沿。
后续，我们将每期推送3名候选人信息，直至全部候选人推送完毕。
本期是工作市场候选人信息第40期内容，也是 UC-San Diego 第5期内容。

Consequences of Indian Import Penetration in the US Pharmaceutical Market
Indian pharmaceutical firms vastly increased generic drug exports to Western countries, and particularly the United States, in response to India amending its patent protection law in 2005. This paper demonstrates that Indian import penetration in the U.S. pharmaceutical industry was stronger among drugs that included active pharmaceutical ingredients which Indian firms had the capability to manufacture before 2005. These 'treated' drugs experienced a larger drop in prices and increased competition from Indian firms. However, non-Indian firms responded to the trade shock by exiting 'treated' drugs, in that they were more likely to discontinue and less likely to newly register 'treated' drugs. This strategic change was stronger for firms with larger shares of drug sales exposed to Indian import penetration. Rather than exploring new pharmaceutical ingredients, non-Indian firms opted to continue selling drugs they already had experience producing. The law change also led to disruptions in foreign supply chains, with 'treated' drugs facing more drug shortages. These findings show how competition in the pharmaceutical industry is shaped by supply side shocks and how a trade-driven influx of competition could crowd out incumbent firms.

An Axiomatic Test for Salience and Regret Theory
Salience and regret theories describe how the manipulation of relative differences between potential outcomes of risky options affects individuals’ decisions. In this project, I present axiomatizations for both theories. The axioms for salience theory formulate hypotheses concerning preferences for a large difference in outcomes compared to the summation of smaller differences that partitions it. To test these axioms, we conduct an online experiment with 800 participants. The current experiment finds supportive evidence for both theories at the aggregate level. However, there’s notable heterogeneity in the results: The violation rates of our main hypotheses are between 39% to 72%

Intergenerational Persistence in Intimate Partner Violence: Evidence from African Women
Violence against women by male partners is a pervasive global human rights violation and public health issue with large economic and social costs. The intergenerational persistence of intimate partner violence (IPV) victimization holds important implicatio ns for inequality and its long - term survival. We estimate mother - daughter associations in IPV victimization using representative survey data from 16 countries in Sub - Saharan Africa, a region of the world with particularly high IPV rates. We find that persi stence is large in both levels and relative magnitudes. Women who report that their mother was physically abused by their father are 26 percentage points (1.9x) more likely to report physical or sexual violence from their current spouse. We then explore th e role of cultural transmission. We find robust evidence for parental socialization, where daughters’ exposure to interparental violence increases their reported acceptability of IPV, and mixed evidence for the role of assortative matching in the marriage market on these attitudes.
