It is commonly argued that Japanese trade protection has enabled the nurturing and development internationally competitive firms. The results in our paper suggest that when it comes to TFP growth, this view of Japan is seriously erroneous. We find that lower tariffs and higher import volumes...

We develop a simple model of the choice between exploiting a technology in another country via export and via direct foreign investment. The model points to the destination country's size, level of technological sophistication, and distance from the source as factors in the decision. Moreover,...

The export booms in South Korea and Taiwan starting in the early 1960s are anomalous when compared with later export booms in other, non-East Asian countries such as Chile and Turkey. First, these booms have taken place in the context of comparatively small changes in relative prices in favor of...

Most explanations of Korea's and Taiwan's economic growth since the early 1960s place heavy emphasis on export orientation. However, it is difficult to see how export orientation could have played a significant causal role in these countries' growth. The measured increase in the relative...

This paper investigates the determinants of countries' export performance looking in particular at the role of international product market linkages. We begin with a novel decomposition of the growth in countries' exports into the contribution from increases in external demand and from improved...

Unlike most countries, Korea did not implement a lockdown in its battle against COVID-19, instead successfully relying on testing and contact tracing. Only one region, Daegu-Gyeongbuk (DG), had a significant number of infections, traced to a religious sect. This allows us to estimate the causal...

Gender disparities in academic performance may be driven in part by the interaction of teacher and student gender, but systematic sorting of students into classrooms makes it difficult to identify causal effects. We use the random assignment of students to Korean middle school classrooms and...

Previous research has shown that women in the treatment group of the CeMENT randomized controlled trial increased their publications and the likelihood that they were tenured in top 50 economics departments. This paper examines one potential mechanism, namely, that CeMENT expanded the...

This paper extends my research applying statistical decision theory to treatment choice with sample data, using maximum regret to evaluate the performance of treatment rules. The specific new contribution is to study as-if optimization using estimates of illness probabilities in clinical choice...

We study whether savings nudges have the unintended consequence of additional borrowing in high-interest credit. We use data from a pre-registered experiment that encouraged 3.1 million bank customers to save via SMS messages and train a machine learning algorithm to predict individual-level...
