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 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.

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).
Congratulations to Economics faculty members Michele Baggio and Kai (Jackie) Zhao, who have received promotion to tenured Associate Professor, and to Steven Lanza, promoted to Associate Professor in Residence!
The UConn Board of Trustees approved the promotions, effective August 23rd, at the Board meeting on Wednesday, April 24th.
Professor Zhao’s paper “The Chinese Saving Rate: Long-Term Care Risks, Family Insurance, and Demographics” has been accepted for publication in the Journal of Monetary Economics, a top macro journal.
In this article, Professor Zhao and his coauthor find that the combination of the risks faced by the elderly and the deterioration of family insurance due to the one-child policy is an important cause of the increase in China’s saving rate since 1980. This paper is the first major paper growing out of their research agenda on the Chinese economy and its implications for the rest of the world.

An article by Professor Zhao and his coauthor Ayse Imrohoroglu (USC Marshall) has been posted on VoxChina.org, an independent, non-partisan and nonprofit platform recently initiated by Princeton together with a group of scholars from other institutions including UPenn and CUHK (Shenzhen).
In this article, they discuss their research on the determinants of the Chinese saving rates. They focus on the paper “The Chinese Saving Rate: Long-Term Care Risks, Family Insurance, and Demographics”, in which they find that the combination of the risks faced by the elderly and the deterioration of family insurance due to the one-child policy is an important cause of the increase in China’s saving rate since 1980. This paper is the first major paper growing out of their research agenda on the Chinese economy and its implications for the rest of the world.

Professor Kai Zhao has had his paper titled “Social Insurance, Private Health Insurance and Individual Welfare” accepted for publication in the Journal of Economic Dynamics and Control. In this paper, he develops a quantitative dynamic general equilibrium model to evaluate social insurance policies. The main findings of the paper are that means tested social insurance does not only distort saving and labor supply decisions, but also has a large crowding out effect on the demand for private health insurance. However, despite the distorting effects, the net welfare consequence of eliminating social insurance is still negative. In addition, this paper finds that the existence of social insurance as a last resort is a quantitatively important reason why many Americans choose to be uninsured.
Professor Zhao and his coauthor Ayse Imrohoroglu (USC Marshall) have their paper titled “Intergenerational Transfers and China’s Social Security Reform” accepted for publication in the Journal of the Economics of Ageing. This paper grew out of their research agenda on the Chinese economy and its implications for the rest of the world. In it, they find that a model with two-sided altruism is preferred to a standard pure life-cycle model for studying social security reforms in China due to the prevalence of intergenerational links. They show that the implications of several reforms are quantitatively different from what have been found in existing studies using pure life-cycle models.

Professor Zhao was a panelist at The 9th Annual Conference on China’s Economic Development and the U.S.-China Relationship, held at The George Washington University. The panel was on China’s Macroeconomy, Urban Growth and Policy Analysis.
In it, Professor Zhao discussed his recent research on the Chinese Saving Rate.

Professor Zhao presented his research on the impact of health insurance policies on aggregate labor supply as part of the 2016 Seminar Series at the St. Louis Fed, on May 4, 2016.
In his research, he investigates whether or not the different health insurance policies in the United States and Europe can explain the fact that Americans work more hours than Europeans.
For more information, see the St. Louis Fed website.
Professor Kai (Jackie) Zhao has had his paper “Social Security and the Rise in Health Spending” accepted for publication in the Journal of Monetary Economics.
In a quantitative model of Social Security with endogenous health, I argue that Social Security increases the aggregate health spending of the economy because it redistributes resources to the elderly whose marginal propensity to spend on health is high. I show by using computational experiments that the expansion of US Social Security can account for over a third of the dramatic rise in US health spending from 1950 to 2000. In addition, Social Security has a spill-over effect on Medicare. As Social Security increases health spending, it also increases the payments from Medicare, thus raising its financial burden.
Congratulations, Professor Zhao!
Professor Kai Zhao has had his article titled “War Finance and the Baby Boom” for publication in Review of Economic Dynamics.
The abstract of the article is below.
In this paper, I extend the Barro-Becker model of endogenous fertility to incorporate specific fiscal policies and use it to study the effects of the fiscal policy changes following WWII on fertility in the United States. The US government went through large changes in fiscal policy after the beginning of WWII. The marginal income tax rate for an average American jumped from 4% on average before 1940 to approximately 25% during the war and stayed around 20% afterwards. The government debt-GDP ratio jumped from approximately 30% on average before WWII to 108% in 1946 and then dropped gradually in the following two decades to about 30% again at the end of 1960s. I find that the dramatic increase in the marginal income tax rate was an important cause of the postwar baby boom in the US because it lowered the after-tax wage and thus the opportunity cost of child-rearing. I also find that the differential change in taxes by income was an important reason why the baby boom was more pronounced among richer households (as documented by Jones and Tertilt (2008)). Furthermore, I argue that the government’s debt policy may also matter for understanding fertility choices because government debt implies a tax burden on children in the future and thus affects their utility, which is a key determinant of current fertility choice in the Barro-Becker model. The results of a computational experiment show that the US government’s postwar debt policy also contributed to the baby boom, but its quantitative importance is relatively small.
