Recent Research

Local soda taxes are mostly ineffective:
In our recent working paper (with Stephan Seiler and Anna Tuchman), we analyze the impact of a tax on sweetened beverages in Philadelphia, often referred to as a “soda tax.” We find that the tax leads to a 30-40% price increase for unhealthy beverages such as soda. Demand in the taxed area decreases dramatically by 42%. However, cross-shopping outside of Philadelphia completely offsets the reduction in sales within the taxed area, and there is little substitution to untaxed beverages (water and natural juices). Consequently we find no significant reduction in calorie and sugar intake, and the city's soda tax revenue falls short. MarketWatch and National Review have reported this paper.

Runner-up for Dick Wittink best paper award: 
The impact of advertising along the conversion funnel
My research published in Quantitative Marketing and Economics (with Stephan Seiler) has just won the runner-up for the Dick Wittink best paper award at the journal. In the paper we combine path-tracking data with advertising data, and analyze advertising effectiveness along the conversion funnel in brick-and-mortar supermarkets. My coauthor Stephan discusses the insights of the paper in the following interview.

The unintended consequence of intermediaries of online microfinance platform
In a recent paper (with Bryan Bollinger, forthcoming at Quantitative Marketing and Economics), we investigate how the current practice of using intermediaries by online microfinance platforms may cause unintended effects, leading to inflated interest rates for borrowers. We propose an alternative repayment mechanism that can eliminate the negative consequence of intermediaries.
