A growing body of rigorous research shows that financial services innovations can have important positive impacts on wellbeing, but also that many do not. We first describe the latest evidence on what works in financial inclusion. Second, we summarize research on key financial market failures...

The privatization of social services is being increasingly discussed. The social services market is characterized by multiple market failures, including informational asymmetries, agency problems, externalities, and distributional concerns. Consumers may care as much or more about quality of...

This Handbook chapter seeks to introduce students and researchers of industrial organization (IO) to the field of market design. We emphasize two important points of connection between the IO and market design fields: a focus on market failures--both understanding sources of market failure and...

This is an invited chapter for the forthcoming Volume 4 of the Handbook of Industrial Organization. We summarize the state of the literature on the economics of innovation and highlight open policy questions. We first articulate the key market failures in markets for innovation, and then discuss...

Circular Economy literature recommends longer lasting products, in order to reduce pollution from extraction, production, and disposal. Our economic analysis finds conditions where consumers choose lives that are too short - a "durability gap". Then policies targeting durability raise welfare....

I consider the effect of caring, empathy, altruism or positive reciprocity towards others - which I collectively call positive preference interdependence (PPI) - on the internalization of interpersonal externalities and on the level of private contributions to the provision of public goods. I...

We examine constraints to adoption of new technologies in the context of hillside irrigation schemes in Rwanda. We leverage a plot-level spatial regression discontinuity design to produce 3 key results. First, irrigation enables dry season horticultural production, which boosts on-farm cash...

Regulation of economic activity is ubiquitous around the world, yet standard theories predict it should be rather uncommon. I argue that the ubiquity of regulation is explained not so much by the failure of markets, or by asymmetric information, as by the failure of courts to solve contract and...

Energy efficiency and conservation are considered key means for reducing greenhouse gas emissions and achieving other energy policy goals, but associated market behavior and policy responses have engendered debates in the economic literature. We review economic concepts underlying consumer...

Economists argue that rich information environments and formal enforcement of contracts are necessary to prevent market failures when information asymmetries exist. We test for the necessity of formal enforcement to overcome the problems of asymmetric information by estimating the value of...
