In their own words…

IEA: Can you tell us what made you pursue a career in economics?

Huayu: I was born in a small village in Central China, a place less developed than most other areas in the country. While I witnessed substantial improvements in living standards as I grew up, I was astonished by the immense developmental gap between my home village and big cities once I had the chance to study in Beijing. Why do some regions tend to be more prosperous than others? What policies could help less developed regions such as my hometown to catch up? How should these policies be implemented? These are the questions that puzzled and intrigued me. They motivated me to study economics and to pursue a doctoral degree at the University of Michigan. As a graduate student, I learned to combine rigorous empirical methods with economic theory to analyze important questions related to policymaking and economic development. In collaboration with governments and firms in India and China, I have also implemented several randomized intervention programs targeting disadvantaged populations. After graduation, I was fortunate to be able to join the National School of Development and ISSCAD at Peking University. This is a platform which allows me to participate in policy debates in China, and share knowledge and experience with global leaders from other developing countries. I chose this career because it has allowed me to continue seeking answers to questions that I care about, and gives me a platform to make a real difference, not just to my small home village, but to the developing world as a whole.

 

IEA: You have done some very interesting research on the determinants of state and local policies in China (as in your work on allocation of industrial land). Can you tell us how this work reinforces — or forces us to rethink — conventional accounts of the Chinese economic development model?

Huayu: Conventional studies on China’s political economy tend to attribute China’s economic success to a performance-based promotion tournament between local government officials. This model assumes that the promotion of local officials is determined by economic growth in their retrospective jurisdictions. In addition, local officials are regarded as self-interested agents driven purely by career advancement incentives. As a result, they implement pro-growth policies and programs so as to compete for promotion. However, government officials do not operate in an institutional vacuum; they are embedded in a network of social relationships that may also shape their incentives and behaviors. Many recent studies have shown that in addition to career concerns, politicians and bureaucrats are motivated by social incentives. My recent work on the allocation of industrial land is an example of this. Using georeferenced data on each parcel of land supplied by Chinese local governments for industrial activities, coupled with detailed biographical data on local government officials, I provide evidence that local officials tend to shift industrial activities from areas upstream of their home regions to areas upstream of other regions. This protects residents of their hometowns from industrial pollution. However, it comes at the expense of economic efficiency and government income. These findings point to the importance of local officials’ social networks and non-pecuniary incentives in determining government policy. It is important to incorporate this into China’s development models since it explicates regional variations in policymaking and development. Given the prevalence of social network ties between upper- and lower-level government officials within the Chinese political arena, it may also be worth rethinking the meritocracy assumption about the promotion of local officials, as well as personnel policies that may improve the quality of bureaucrat selection.

IEA: You recently published a study on China’s Household Responsibility System (HRS) reform. Can you tell us what you found and why it matters?

Huayu: The Household Responsibility System (HRS) reform is probably China’s most far-reaching economic reform to date. It has assigned collectively owned farmland to individual households with secure tenures, which in turn, has boosted labor productivity among rural populations. Although much is known about how this reform has contributed to poverty reduction and China’s economic growth, less is known about how it has affected the well-being of targeted populations over the long term. In this paper, I take advantage of the regional variation in reform timing and pace to evaluate the long-term impacts of HRS reform on individuals’ human capital and labor market outcomes. My findings show that due to increased household resources, the reform significantly improved later-life health, education, and labor market performance for those exposed at early-life stages. However, since the reform decreased returns to education and increased returns to young labor, it discouraged human capital investment in children exposed at critical school ages. Consequently, this lowered their mobility in adulthood. Many policymakers tend to focus on short-term economic implications. This study shows that policy reforms may also have important long-term consequences on targeted populations, especially those who have experienced the change at critical life periods. This study also shows that the same policy can have distinct effects on different populations. Some people may even be hindered by reforms that are widely regarded as improving efficiency. Thus, additional government assistance is needed to prevent vulnerable populations from harm.

IEAResearchers based in developing countries sometimes face serious obstacles in accessing research networks that are located largely in advanced countries. Would you have some advice for young scholars who are starting off their careers outside those established networks?

Huayu: Firstly, I would like to point out that researchers based in developing countries also have their own advantages. For instance, they have better access to policy experiments and historical episodes which have been understudied by researchers in advanced countries. It is also more convenient for them to conduct randomized experiments given the lower labor costs and greater willingness to participate on the part of governments and firms. These advantages can make researchers based in developing countries valuable assets to research teams in advanced countries. So I think we should use these advantages to seek collaboration with, and integrate into, those established research networks. In addition, the virtual environment has compressed the distance between researchers regarding their nationalities and physical locations. There are just so many online workshops and conferences nowadays, which allow us to present our research and dialogue with researchers who share similar interests. I think we should take advantage of this as well.
