The strategy method (SM) is, in practice, subject to a possibly severe economic-theoretical bias. Although many studies utilize SM to examine responses to rare or off-equilibrium behaviors unattainable through direct elicitation (DE), they ignore the fact that the strategic equivalence between SM...

Research shows that opposition to policies that redistribute across racial divides has affected the development of the American welfare state. Are similar dynamics at play in Western Europe? For many scholars, the answer is yes. In contrast, we argue that researchers' understanding of the political...

Payments for Environmental Services (PESs) are increasingly used to foster farmers’ adoption of greener practices, but their effectiveness is often undermined by low enrollment. In a large randomized field experiment (N = 20,000), we test several non-monetary incentives to increase enrollment into...

Tech giants' dominance does not confront us with an unpalatable choice between laissez-faire and populist interventions. This article takes stock of available knowledge, considers desirable adaptations of regulation in the digital age, and draws some conclusions for policy reform.

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...

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...

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...

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...

Using data collected from one of the most popular ridesharing platforms, we illustrate how mobility has changed after the exit from the Covid-19 induced confinement. We measure the impact of the Covid-19 outbreak on the level of mobility and the price of ridesharing. Finally, we show that the...
