Professor Kai Zhao to be published in Review of Economic Studies

Posted on by

Professor Kai Zhao’s paper, “How Important Is Health Inequality for Lifetime Earnings Inequality?” (with Roozbeh Hosseini and Karen Kopecky), has been accepted for publication in the Review of Economic Studies, one of the top five academic journals in Economics.

In this paper, Professor Zhao and his coauthors examine an often-overlooked driver of economic inequality: health disparities. They show that health inequality is not just a reflection of broader economic disparities but a key driver of them.

Abstract:

Using a dynamic panel approach, we provide empirical evidence that negative health shocks significantly reduce earnings. The effect is primarily driven by the participation margin and is concentrated among the less educated and those in poor health. Next, we develop a life cycle model of labor supply featuring risky and heterogeneous frailty profiles that affect individuals’ productivity, likelihood of access to social insurance, disutility from work, mortality, and medical expenses. Individuals can either work or not work and apply for social security disability insurance (SSDI/SSI). Eliminating health inequality in our model reduces the variance of log lifetime (accumulated) earnings by 28 percent at age 55. About 60 percent of this effect is due to the impact of poor health on the probability of obtaining SSDI/SSI benefits. Despite this, we show that eliminating the SSDI/SSI program reduces ex ante welfare.

Fall 2024 GA Training Workshop: Faculty Insights

Posted on by

Last Thursday, October 17, 2024, the Department of Economics held its regular semester GA Training Workshop, aimed at preparing new Graduate Assistants for their teaching responsibilities. Three faculty members—Professors Talia Bar, Professor Kai Zhao, and Professor Tianxu Chen—shared valuable advice drawn from their teaching experience.

Professor Bar emphasized the importance of adapting to students’ varying levels of mathematical proficiency, using active learning strategies to keep students engaged, and proactively addressing potential classroom challenges.

Professor Zhao reflected on his early teaching experiences, offering advice on understanding student backgrounds, using relatable examples, and ensuring clear communication to avoid confusion.

Professor Chen concluded the session by focusing on classroom management, encouraging a positive learning environment, and balancing teaching duties with academic responsibilities. Her practical tips provided GAs with useful strategies for success.

This workshop remains a cornerstone of the department’s efforts to support GAs, offering them essential tools and insights to excel in both teaching and their academic progress each semester.

Recent UConn graduates Aaron Cooke (2018 PhD, U.S. Department of the Treasury) and Umesh Ghimire (2021 PhD, Commonwealth University of Pennsylvania) have had their paper accepted for publication in Macroeconomic Dynamics.

The paper examines the impact of life-cycle savings, intergenerational transfers, and fertility differences between the rich and the poor on the wealth distribution in the United States

This paper is a joint work with Dr. Hyun Lee (former UConn faculty) and Professor Kai Zhao. The key message of the paper is that the fertility differences between the rich and the poor significantly amplify the role of bequests in shaping the U.S. wealth inequality.

Professor Zhao published in Review of Economic Dynamics

Posted on by

Professor Zhao’s paper “The Evolution of Health over the Life Cycle” has been published in the Review of Economic Dynamics.

In this paper, Professor Zhao and his coauthors construct a unified objective measure of health status: the frailty index. Using this index, they propose and estimate a stochastic process for health dynamics over the life cycle accounting for mortality bias. Their health measure and dynamic process can be used to study the evolution of health over the life cycle and its economic implications.

Building on this work, Professor Zhao and his coauthors are currently working on a project that explores the evolution of health inequality over the life cycle and its implication for lifetime earnings inequality.

Recent PhD publishes in Journal of Economic Behavior and Organization

Posted on by

Recent PhD graduate Fei Zou has published “Does Early Retirement Really Benefit Women?” in the Journal of Economic Behavior and Organization.

This paper grew out of Fei’s PhD dissertation completed at UConn (2019) under the supervision of Professor Kai Zhao. It is a joint work with Dr. Hyun Lee (former UConn faculty), and Professor Zhao.

In this paper, the authors quantitatively evaluate the welfare consequences of China’s gender-specific mandatory retirement policy using a calibrated overlapping generations model with heterogeneous agents and incomplete markets. They find that while it is intended to relieve women from work earlier and to provide them with more years of public pensions benefits than men, early mandatory retirement reduces welfare for women.

Professor Agüero and Professor Zhao have received CLAS Summer Funding for their research projects, respectively. Professor Agüero’s project will conduct an experimental intervention providing information about college scholarships to disadvantaged high school students in Peru to motivate their study efforts during the Covid-19 pandemic. The project has also received the approval of the Ministry of Education.

Professor Zhao received funding for his project titled “Health Inequality over the Life Cycle and Its Implications for Economic Well-Being”. In this project, Professor Zhao and his coauthors examine the relationship between health inequality and lifetime earnings inequality, paying close attention to the role of Social Security Disability Insurance (SSDI) in facilitating the tradeoff between health and economic well-being.

Econ PhD Alumnus is Chief Economist for Macro Policy at the CEA

Aaron Cooke, a 2018 PhD graduate of the UConn Department of Economics, recently became the Chief Economist for Macroeconomic Policy at the Council of Economic Advisers (CEA).

The CEA, an agency within the Executive Office of the President, is charged with offering the President objective economic advice on the formulation of both domestic and international economic policy.

Aaron earned his PhD degree from the Department of Economics in 2018, specializing in macroeconomics and public policy. His PhD dissertation, “Three Essays on Wealth and Income Inequality”, studied the causes of U.S. wealth and income inequality, and was completed under the supervision of Professor Kai Zhao.

Prior to joining the CEA, Aaron was an economist at the Office of Management and Budget.

Professor Zhao’s Research to be Published in International Economic Review

Posted on by

Professor Zhao’s paper “Household Saving, Financial Constraints, and the Current Account in China” has been accepted for publication in the International Economic Review.

In this paper, Professor Zhao and his coauthor find that the rise and fall in China’s current account surplus was largely due to (1) the rising household saving driven by the decline in family insurance coupled with inadequate public insurance, and (2) the variation in financial constraints facing the Chinese firms.

The working paper version of this research can be found in the UConn working paper series: https://ideas.repec.org/p/uct/uconnp/2018-15.html.

International Economic Review publishes cutting edge papers in many areas of economics, including econometrics, economic theory, macro, and applied economics. It is considered one of the leading journals in economics in the world (Engemann and Wall, 2009).
