I am an economist resesarching how individuals, the elderly in particular, make personal finance decisions such as retirement savings and mortgages. I also study how the government regulation impacts the insurance market. I have over 10 years of experience in data analytics, statistical modeling and causal inference.
My current job is a postdoctoral research associate at the University of Sydney Business School and an associate investigator at the ARC Centre of Excellence in Population Ageing Research (CEPAR). I received my Ph.D. in Risk and Insurance at the Wisconsin School of Business, University of Wisconsin–Madison.
1. Medicaid and Long-Term Care: The Effects of Penalizing Strategic Asset Transfers (with Anita Mukherjee) (Journal of Risk and Insurance, 2021)
Abstract: Medicaid provides a critical source of insurance for long-term care, and individuals may strategically offload assets (typically to children) to meet the means-tested eligibility requirement. In this paper, we quantify the extent of such behavior using variation in the penalty for improper parent-to-child transfers induced by the Deficit Reduction Act of 2005. We estimate difference-in-differences models based on the hypothesis that only individuals with high levels of nursing home risk (high risk) will alter transfers because of the Act. We find that over a two-year horizon, high risk individuals reduced transfers to children on the extensive margin by 11 percent and that the average total amount of transfers decreased by $4,860. The results hold only for coupled respondents. We also conduct a triple-differences analysis to examine heterogeneity with financial literacy and find that even those with a low level of financial literacy responded to the penalty.
2. Building Financial and Health Literacy at Older Ages: The Role of Online Information (with Hessam Bavafa and Anita Mukherjee) (Journal of Consumer Affairs, 2019)
Abstract: Improving financial and health literacy is an important step in reducing economic vulnerability in older age, yet the means by which individuals accumulate these types of human capital remains an open question. This paper evaluates the impact of online search activities on the levels of financial and health literacy. We find that using the internet for such information increases literacy significantly: doing so frequently (versus not at all) increases financial literacy by 16 percent and health literacy by 12 percent. Our results are robust to alternative measures of financial literacy. They are also robust to an instrumental variable approach using other web skills such as email use to proxy for how individuals use the internet.
Abstract: Regulation of contracts plays an important role in U.S. financial markets. We estimate the costs of complying with contract regulation by exploiting the rich cross-sectional and time-series variation in regulation in the U.S. property-liability (P/L) insurance industry. We find that the costs of complying with stringent contract regulation are significantly greater than the costs of complying with flexible contract regulation, with the estimate of the difference being 3.1 percent of the general expenses for the average insurer in each line of business and year. Our estimates imply that stringent contract regulation increases expenses in the industry by $1.8 billion per year. The compliance costs are higher in personal lines of insurance. The burden of these costs falls unevenly on insurers, with the regulatory effects isolated to the firms writing less than $5 million in premiums in a line of business per year.

Abstract: We study whether digital technology streamlines the regulatory process and reduces the costs of complying with regulation. To identify the effect of digital technology on regulatory compliance costs, we leverage a quasi-experimental policy change which mandates the use of an internet-based flow management tool that enables insurers and regulators to exchange policy form and rate ling information. We find that digitization lowers the costs of complying with regulation. The average insurer per line of business and year in the highest quartile regarding the proportion of business under the mandate saves 5.4 percent of general expenses. Our results also suggest a fixed cost of adopting the technology, with larger cost-saving accruing to firms that adopt the new technology more widely.

Abstract: Complex financial products such as home mortgages have many features and are offered in staggering variety, leading many households to turn to brokers for assistance with their choice of loan, lender and repayment plan. In this study we use stated preference methods – a best-worst task and discrete choice experiment – to build a deeper understanding of how perceptions of mortgage attributes (subjective ratings of confusion and importance) influence borrowers’ valuation of mortgage attributes and how those valuations vary when borrowers have consulted brokers. Analysis of best-worst responses show that most borrowers are highly confused about some common contract features – maximum loan-to-value ratio, compulsory lender’s mortgage insurance and loan portability – but consider the level of interest rate, the ability to make extra repayments and ARM/FRM as the most important attributes. However borrowers who have consulted brokers express generally less confusion and consider a wider range of attributes in their deliberations. Estimates from a hierarchical mixed logit model show that, compared to borrowers who have no experience of using brokers, older broker-advised borrowers place value on avoiding high establishment fees, and younger and more educated broker-advised borrowers are more likely to accept longer loan terms and have a low preference for principal and interest payment schedule and the flexibility of early repayments.

Abstract: The Australian COVID-19 Early Release Scheme (ERS) allowed people in financial hardship immediate access to up to $A20,000 of their ‘preserved’ retirement savings between April and December 2020. Using data from a large Australian pension fund, we examine what drives people’s decisions to take advantage of the ERS. We find that while the majority of survey respondents withdrew money for immediate consumption needs, a substantial proportion of them were concerned about future needs. Most withdrawers thought about the decision for less than a week and many appeared to use the $A10,000 per round limit as an anchor in choosing their withdrawal amount. Conditional on eligibility, the probability of withdrawal was significantly higher where respondents (i) were more concerned about future needs, (ii) did not think about the long-term impact, and (iii) under-estimated or did not estimate the fall in their retirement savings. Our results suggest that many people who withdrew under the scheme did not fully understand the consequences of their choice. These findings raise the question of whether the framing of ‘mandatory’ retirement savings as a mental account to finance retirement has been irrevocably damaged.

8. Rate Regulation Revisited: Does Stringent Regulation Impact Insurance Prices? (with Ty Leverty)
This study reinvestigates the effect of stringent rate regulation on prices in the U.S. property-liability industry. Despite a rich literature on insurance rate regulation, the short-term and long-term impact of stringent rate regulation on insurance prices remains unclear. We extend this literature using data at the firm-line-state level, which allows us to estimate fixed effects regressions that exploit different sources of variation in rate regulation – across states, over time, and across lines – to determine whether and how stringent rate regulation affects prices. We find that, on average, stringent rate regulation lowers the unit price of insurance. The magnitude and duration of the influence of stringent rate regulation on price vary over time, with the biggest impact in the early 2000’s during and after a wave of deregulation.
