"FinTech and Household Finance: A Review of the Empirical Literature"
(with Sumit Agarwal), China Finance Review International, 2020
Winner of the Emerald Literati Awards for Outstanding Paper
Abstract: This paper reviews recent advances in the empirical literature of FinTech and household finance. We survey the effects of FinTech on three different aspects of household finance: payments, lending and portfolio decisions. Specifically, we examine the impact of digital payments, mobile money, FinTech lending, marketplace lending, robo-advising and crowd-funding. Studies suggest that FinTech has positively benefited households by increasing consumption and borrowing. This allows them to smoothen their consumption across time. Furthermore, there is an improvement in their portfolio diversification. Nonetheless, there is also evidence that certain households overconsume and borrow beyond their means. Despite the importance of this topic, there has been a lack of empirical evidence until recently. In this paper, we take stock of the empirical evidence in the literature through the lens of household finance
"Inflation Expectations of Households and the Upgrading Channel."
(with Sumit Agarwal and Changcheng Song), Journal of Monetary Economics, Volume 128, May 2022, Pages 124-138.
Abstract: This paper combines several administrative data and a survey experiment to evaluate the role of lifestyle changes in influencing inflation expectations. Using data from Nielsen’s Homescan Panel, as well as a leading bank in Singapore, we first document that households are upgrading across categories and within categories of goods. We then use a survey experiment to show that price information of better-quality products will lead to higher inflation expectations. The effects on inflation expectations are smaller when the price information of both higher and lower quality products is made available, implying that increasing product variety of lower quality products reduced inflation expectations. Frequent shoppers tend to allocate more weight on higher quality goods when forming inflation expectations. These results suggest that exposure to better quality goods plays an important role in the formation of inflation expectations. Moreover, we map the personal shopping experience with our survey at the group level and find a positive relationship between the increase in quality of supermarket shopping and inflation expectations. Our findings highlight the relationship between personal experience, product variety and inflation expectations.
