We study differences in the effects of prices, non-price promotions, and brand line length on brand shares at different retail formats. Our conceptual framework rests on the presence of trip level fixed and category level variable utility components and shows how the trade-off between these...

Vaccines exert a positive externality, reducing spread of disease from the consumer to others, providing a rationale for subsidies. We study how optimal subsidies vary with disease characteristics by integrating a standard epidemiological model into a vaccine market with rational economic...

This paper examines the effectiveness of the administrative fines imposed by the European Commission on cartels from an economic perspective. It reviews the theory, practice, and evidence of optimal fines and assesses whether the European Commission fines, leniency, and settlement procedures...

What happens to market structure as an industry’s operations lean ever more on software? We find that software availability is associated with an increase in entry and an increase in exit by the oldest and most established firms. We formalize alternative mechanisms by which this could happen...
