Fines, corporal punishments, and other procedures of punitive justice recur across small-scale societies. Although they are often assumed to enforce group norms, we here propose the relation-restoration hypothesis of punitive justice, according to which punitive procedures function to restore...

We investigate the ability of a platform to design its marketplace to promote competition, improve consumer surplus, and increase its own payoff. We consider demand‐steering rules that reward firms that cut prices with additional exposure to consumers. We examine the impact of these rules both in...

Low-income individuals are typically the most price sensitive segment of the mar-ket, but this is not true in the market for health care services. I show that low-income individuals have a smaller demand elasticity of medical spending with re-spect to coinsurance, relative to their higher income...

Due to the switching behavior of online consumers, news outlets increasingly compete with each other to attract audience for each single news item they produce, rather than for complete editions of their newspapers: the so called unbundling of journalism. Using a standard Hotelling model, I show...

We analyze the consequences of noisy information aggregation for investment. Market imperfections create endogenous rents that cause overinvestment in upside risks and underinvestment in downside risks. In partial equilibrium, these inefficiencies are particularly severe if upside risks are coupled...

This paper uses an evolutionary game theory approach to assess the diffusion of different hydrogen technologies in the air transport system. Our model is extended to consider uncertainty, as well as the impact of the “Flight Shame” movement and different policies such as subsidies or taxes. A...

The cost of germline maintenance gives rise to a trade-off between lowering the deleterious mutation rate and investing in life history functions. Therefore, life history and the mutation rate coevolve, but this coevolution is not well understood. We develop a mathematical model to analyse the...

We develop a model of a device ecosystem to study how network structure affects demand, pricing, and output for the underlying products. Prices depend on each device's Katz-Bonacich centrality in a network defined by the demand-side externalities linking devices. We show how the relevant network...

Climate change poses an existential threat. Theoretical and empirical research suggest that carbon pricing and green R&D support are the right tools, but their implementation can be improved. Other policies, such as standards, bans, and targeted subsidies, also all have a role to play, but they...
