Faculty Spotlight: Yong Lee

In conversation with Shorenstein APARC, Yong Lee, the SK Center Fellow, discusses his initial draw to architecture and urbanism, and the nexus of public policy and economics. Lee highlights some of his recent research activities focused on international sanctions on North Korea and educational policy as it relates to migration and housing patterns in South Korea. 

Your background is quite multifaceted, including years working in architecture and a master’s of public policy in addition to a doctorate in economics. How do all of these areas fit together to inform your research?

It took a while for me to figure out what I wanted to pursue as a career. As a high school student in Korea I had to choose a track that focused on either the physical sciences or the humanities/social sciences. At that age, it’s hard to know what you want to be. Simply because my father was an engineer, I chose the physical sciences track. When it was time to apply for college (one actually had to determine a major when applying for college back then), I became interested in international relations and wanted to become a diplomat. But given my training in the hard sciences and the fact that one had to choose a major when applying, I had to decide on a science or engineering major. After browsing through the library a few architecture books caught my eye, and I opted for architectural engineering as my major. 

I truly enjoyed my six years of architectural training but after working for an architectural firm for several years in Seoul, I realized I was more interested in the abstract ideas of architecture and urbanism and less of the actual design process that goes on in an architectural firm. I searched for my next career, became interested in urban and development policy, and pursued a master’s of public policy at Duke University. However, then I realized that economics would allow me to rigorously analyze the policy questions I was interested in. Fortunately, Brown University accepted me as a Ph.D. student and I eventually became an economist. It was through this search process, that I developed an interdisciplinary interest in policy relevant questions. My personal choices constrained by education policy, comparatively experiencing Korea’s transition while living between Korea and the United States each decade since the 1980s, and my interest in architecture and cities have shaped my research interest in economic development and growth with a focus on education, firms and cities.  And now being at FSI, I can immerse myself in international studies, something I had wanted to pursue all along. By joining Stanford, I think I finally discovered what I had wanted to do.

One of your research streams looks at the effects of sanctions on domestic populations, looking at the case study of North Korea. How did you derive data about the closed-off regime? What are your key findings?

Research on North Korea is challenging because of the dearth of data. I had been interested in how sanctions impact the domestic population, but to examine this question one would need regional level data within in North Korea. I decided to use the satellite night-lights data, which in recent years has been used as an alternative means to measure economic activity. I found that sanctions actually increase urban-rural inequality. An additional sanctions index increases the urban-rural luminosity gap by about 1 percent. However, if I focus on the more central urban areas the gap increases to about 2.6 percent. Since urban areas are more than ten times brighter than rural areas, the results imply that the gap further increases by 1 to 2.6 percent with additional sanctions.  Furthermore, I find that the urban areas actually get brighter while the rural areas get darker.

Another of your research focuses on the impact of 1970s education policy in South Korea on intergenerational mobility and migration. Can you explain this phenomenon? Does the case of South Korea relate to reform experiences in other countries?

Students in South Korea traditionally had to take an entrance exam to enter high schools. After the exam, high schools would choose students based on the exam scores. Given the variation in school quality, a hierarchy of high schools had existed and students who performed well would enter the top tier high schools. This system was heavily criticized since wealthier families could tutor children to prepare for the entrance exam. Eventually in the mid-1970s, the South Korean government abolished the exam-based system and moved to a school district based system where students would attend high schools based on residential location. By moving away from an exam system to a district system, policymakers hoped that educational opportunities would alleviate the persistence of inequality. However, what I find is that, to the contrary, the district system generated substantial sorting of households by income. Now wealthier households could simply move to districts and cities with the prestigious high schools. Given that the purchase of housing is purely determined by income, school quality became even more segregated by income and actually exacerbated the persistence of inequality across generations. This transition is now happening in several Chinese cities and in the United States – the sorting across school districts by educational outcome has created highly segregated towns. The Korea experiment allowed me to examine not just an equilibrium outcome, but also the transition when the policy changed.

In the coming year, you’ll be teaching courses related to the economies of East Asia. Can you provide an outlook on this?

I’ll be teaching an International Policy Studies course titled, “Economic Growth, Development, and Challenges of East Asia,” in the spring. The course will focus on China, Japan, and Korea, but also draw on Southeast Asian countries, when relevant. I will cover the rapid economic growth in recent decades and development policies pursued. However, I will also cover the current major economic challenges these countries face, some of which are rising income inequality, entrepreneurship, and an aging workforce. I hope to add to our rich set of courses by providing an economics and empirical viewpoint.

Tell us something we don’t know about you.

I sometimes split my sleep. That is, I go to bed to sleep for a few hours and then wake up in the middle of the dark, do some reading or work, and then sleep for one or two hours before I start my morning routine. It started during my high school years and it has stuck with me for quite a while now. Don’t worry, though. I sleep fine most of the time. I just sometimes enjoy the dead of the night.
