We develop an endogenous growth model with heterogeneous firms facing financial frictions, where misallocation emerges explicitly as a crucial endogenous state variable and plays a significant role in driving economic growth through the valuation channel. The model illustrates that transient...

Evidence suggests that the prehistoric Out of Africa Migration has impacted the degree of intra-population genetic and phenotypic diversity across the globe. This paper provides the first evidence that this migration has shaped cultural diversity. Leveraging a folklore catalogue of 958 oral...

Are developing-world cities engines of opportunities for low-wage earners? In this study, we track a cohort of young low-income workers in Brazil for thirteen years to explore the contribution of factors such as industrial structure and skill segregation on upward income mobility. We find that...

This paper uses a large language model to develop an ex-ante measure of the commercial potential of scientific findings. In addition to validating the measure against the typical holdout sample, we validate it externally against 1.) the progression of scientific findings through a major...

We analyze how expropriation risk reduces incentives for innovation and reallocates resources from the innovative sector, building on Romer's(1990) model. Our framework predicts the R&D expenditure, the share of human capital in R&D, the number of patents, technical progress, and economic growth...

Using dissertation research topics found in the EconLit database and large-scale algorithmic methods that identify author demographics based on names, we explore the link between race and ethnicity and fields of economic research. We find that underrepresented racial and ethnic minority (URM)...

Using the EconLit dissertation database and large-scale algorithmic methods that identify author demographics from names, we investigate the connection between the gender of economics dissertators and dissertation topics. Despite stagnation in the share of women among economics Ph.D.s in recent...

This paper evaluates claims about large macroeconomic implications of new advances in AI. It starts from a task-based model of AI's effects, working through automation and task complementarities. So long as AI's microeconomic effects are driven by cost savings/productivity improvements at the...

Laboratory experiments find a robust relationship between decision times and perceived values of alternatives. This paper investigates how these findings translate to experts' decision making and information acquisition in the field. In a stylized model of expert choice between two alternatives,...

This paper contributes to the literature on innovation policies and institutional theory on conditions for effective institutional changes. The "three rights" reform of 26 universities and the mixed ownership reform of Southwest Jiaotong University are important explorations made by China in...
