Green innovation is essential for climate change mitigation, but not all innovative projects deliver equal social value. We consider innovator heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We...

Effective climate change mitigation requires green innovation, but not all projects have equal social value. We examine the role of innovator heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We...

Livestock is known to play a significant role in climate change and to negatively impact global nitrogen cycles and biodiversity. However, economically efficient policies for regulating meat production and consumption are under-researched. In the absence of first-best policy instruments for the...

Transport has significant externalities including carbon emissions and air pollution. Public health research has identified additional social gains from active travel, due to health benefits of physical exercise. Per mile, these benefits greatly exceed the external costs from car use. We...

We evaluate the effect of vehicle recalls on vehicle transactions in the second-hand market. Using a rich dataset of Dutch vehicle registrations, we exploit the quasi-experimental variation in recalls across nearly-identical cars. We find strong heterogeneities across market segment: vehicles...

Despite ambitious climate goals and already substantial stocks of developed fossil energy reserves, development of new fossil energy reserves continues to be high. This raises concerns, as it reinforces the fossil industry’s opportunities and incentives to continue extraction, and may...
