Governments often make public announcements that call into question oligopolistic behavior. Yet little is known about how firms respond to them. We study gasoline retailers' price responses to antitrust announcements shaming them for price gouging during the COVID-19 pandemic. Price effects are...

This article provides an overview of the burgeoning academic literature on price dynamics and price cycles in retail petrol markets. I first present evidence of petrol price cycles, and studies that describe what types of petrol markets tend to exhibit price cycles. I further discuss empirical...

This article discusses structural changes and emerging policy issues in the wholesale and retail sectors of the Australian petrol industry. The evolution of upstream wholesale markets is a globalization story: rapid economic growth in countries like China and India are bringing global crude and...

We use a field experiment to study price discrimination in a market with price posting and negotiation. Motivated by concerns that low-income consumers do poorly in markets with privately-negotiated prices, we built a call center staffed with actors armed with bargaining scripts to reveal the...

We document substantial rigidity in household electricity demand in response to large price shocks. We partnered with an electricity retailer to run a field experiment in which randomly-selected households received discounts of up to 50% on their total electricity bill or up to 95% off their per...

We document how imperfect information generates heterogeneous effects in information treatments with personalized high-frequency feedback and peer comparisons. In our field experiment in retail electricity, we find that high and low energy users symmetrically underestimate and overestimate their...

Information programs that leverage peer comparisons are used to encourage pro-social behavior in many contexts. We document how imperfect information generates heterogenous responses to treatments involving personalized feedback and peer comparisons. In our field experiment in retail...

As gambling becomes increasingly accessible both in the U.S. and worldwide, governments face an important policy question: how should they exploit the industry's growth to raise tax revenues while protecting individuals from the detrimental effects of gambling? Using data on slot machines from...

As gambling becomes increasingly accessible worldwide, governments face an important policy question: how should they exploit the industry's growth to raise tax revenue while protecting individuals from the detrimental effects of gambling? Using data on slot machines from the largest per capita...

We propose a new methodology for estimating demand and cost functions of differentiated products models when demand and cost data are available. The method deals with the endogeneity of prices to demand shocks and the endogeneity of outputs to cost shocks by using cost data. We establish...
