I am an Assistant Professor in the Department of
Economics and Business at Universitat Pompeu Fabra (UPF).
I am also affiliated with the UPF Barcelona School of
Management (BSM) and the Barcelona School of Economics
(BSE). I received my PhD from the Business Economics and
Strategy group at the Coller School of Management, Tel
Aviv University.
My research centers on Quantitative Marketing and
Empirical Industrial Organization, with a primary focus
on firms’ decision-making and empirical consumer behavior
in the Israeli supermarket industry.
My work has appeared in various media outlets,
including national TV, newspapers, and radio
programs.
The latest BSE Summer Forum on Quant Marketing – a
workshop organized together with Stephan Seiler – took
place in Barcelona on June 8-9 2026. For more details,

papers!

Strategic Adaptation to Future Demand Shifts: Evidence from Nutritional Labeling
How well can firms predict and respond to future shifts in consumer demand? We study this question focusing on a nationwide labeling policy for unhealthy food products. To avoid the labels, firms had to commit to costly reformulation in advance, based on anticipated rather than observed consumer responses. Combining hand-collected nutritional data spanning several years with administrative sales data, we show that firms responded strategically: they reformulated products just above the regulatory thresholds, making the minimum changes needed to avoid the labels and bunching just below them. Firms also correctly anticipated consumer responses, targeting reformulation toward the product categories and consumer segments most adversely affected by the labels. This targeting was dominated by larger firms, which captured most of the potential gains from reformulation, while smaller firms captured almost none. We quantify the value of correctly anticipating demand and show that one unintended consequence of the policy was to increase market concentration.
Price Saliency and Fairness: Evidence from Regulatory Shaming
We study the effects of a regulation that required Israeli retailers to display on-the-shelf signs showing the average (cheap) international price of products alongside the local price. We find that prices fell by an average of 8.8%, and more so for products that were initially more expensive. Quantities sold increased, yet were below those predicted by pre-regulation demand elasticities and actual price drops. The adverse impact on demand was larger for more expensive products. To explain these findings, we develop and estimate a model in which consumers dislike unfair pricing. Finally, we discuss implications for optimal pricing and salient thinking.

The Differential Response of Public and Private Firms to Policy Interventions
Expenditure on food represents a considerable share of household spending, and policy-makers are considering various means to reduce food prices. In this paper we investigate the effects of information-enhancing initiative in the Israeli retail food market. The initiative involved a monthly comparison of the price of a fixed basket of 68 popular goods sold by Israeli supermarket chains. Using detailed price information and a difference-in-differences research design, we find a drop of 4% in the basket price. The drop in prices is concentrated among publicly-traded retailers, and it rises after media reports on the results of the basket comparison. Overall, our findings suggest that drawing attention to prices could be an effective means by policy makers to foster competition and reduce prices.
