Decision Support Systems (DSS) with embedded best management practices help reduce pesticide use. However, costly experimentation is necessary to learn about the quality of their data processing and recommendation models. We study farmers’ choices to try such a DSS. Due to order effects, learning...

We provide a non-anthropocentric rationale for implementing a levy on meat consumption due to animal-welfare considerations. It operates as a Pigouvian tax and addresses externalities on farmed animals. Under total utilitarianism, the levy is a subsidy when an animal’s life is worth living, and a...

We study a platform’s incentives to remove IP-infringing products and the effects of holding the platform liable for such infringements on innovation and welfare. We first show that platform liability can lead to either higher or lower commission rates, depending on how screening affects...

We prove the existence of a Markov-perfect equilibrium in randomized stopping times for a model of the war of attrition in which the underlying state variable follows a homogenous linear diffusion. We first prove that the space of Markovian randomized stopping times can be topologized as a compact...

We consider a setting in which a platform matches buyers and sellers, who then wish to transact with each other multiple times. The platform charges fees for hosting transactions but also offers convenience benefits. We consider two scenarios. In one scenario, all transactions must occur on the...

We analyze how private decisions and optimal public policies are shaped by personal and societal preferences, material incentives, and social norms. We show how honor and stigma interact with incentives and derive optimal taxation. We then analyze the expressive role of law as embodying society’s...

A labeling system for green gases, such as green hydrogen and bio-methane, could enable retailers to leverage consumers’ willingness to pay for environmental quality while promoting the adoption of these cleaner alternatives. However, the significant cost gap between green and conventional gases...
