Do new digital consumption channels of music depress sales in old physical ones, or are they complementary? To answer this question, we exploit product-level variations in prices of about 30 million sales and streams of over 300 thousand products observed weekly between 2014 and 2017 for the entire...

Markets are being populated with new generations of pricing algorithms, powered with Artificial Intelligence, that have the ability to autonomously learn to operate. This ability can be both a source of efficiency and cause of concern for the risk that algorithms autonomously and tacitly learn to...

It has long been recognized that economic inequality may undermine the principle of equal responsiveness that lies at the core of democratic governance. A recent wave of scholarship has highlighted an acute degree of political inequality in contemporary democracies in North America and Europe. In...

Does learning reduce or fuel speculative bubbles? We study this issue in the context of the Bubble Game proposed by Moinas and Pouget (2013). Our theoretical analysis based on adaptive learning shows that i) in the long run, learning induces convergence to the unique no-bubble equilibrium, ii) in...

Uncertainty is a ubiquitous component of human economic behaviour, yet people can vary in their preferences for risk across populations, individuals and different points in time. As uncertainty also characterizes many aspects of animal decision-making, comparative research can help evaluate...

We evaluate the impact of a price cap regulation implemented in the Colombian pharmaceutical market between 2011 and 2014. To do so, we take advantage of a unique data set where we observe three sources of variation: i) differences across eighteen groups in the Anatomical Therapeutic Chemical (ATC...

This article explores a three‐party contracting problem when the patient and the provider possess private information that is unobservable to the insurer. We show that for an insurance mechanism to be collusion‐proof, it suffices for the insurer to rely on the incentive for one side of the patient‐...

We compared the effectiveness of basket goal-setting to product information strategies on sustainable consumption in a simulated online supermarket. Experiment 1 found a significant effect of basket goal setting techniques with carbon basket feedback in either numerical or graphical form on the...

Standard benefit-cost analysis often ignores distortions caused by taxation and the heterogeneity of taxpayers. In this paper, we theoretically and numerically explore the effect of imperfect taxation on the public provision of mortality risk reductions (or public safety). We show that this effect...

This paper provides novel insights into the science of scaling by examining an edu-cational mentoring program in Mexico. The analysis encompasses two independent field experiments, and seizes a unique opportunity to learn from the government’s implementation of the same intervention. While the...
