How does trading in one venue affect the quoting strategies of market makers in other venues? We develop a two-venue imperfect competition model in which market makers face quadratic costs when absorbing shocks. Nonconstant marginal costs imply that absorbing a shock in one venue simultaneously...

This paper summarizes what is known about the impact of public–private partnerships (PPPs) in the three sectors where they have been used intensively: infrastructure (energy, transport, water and sanitation, and telecommunications), education, and health. It lays out the main elements of economic...

With the progress of artificial intelligence and the emergence of global online communities, humans and machines are increasingly participating in mixed collectives in which they can help or hinder each other. Human societies have had thousands of years to consolidate the social norms that promote...

The 50-year old concept of an evolutionarily stable strategy provided a key toolfor theorists to model ultimate drivers of behaviour in social interactions. Fordecades, economists ignored ultimate drivers and used models in which individ-uals choose strategies based on their preferences—a proximate...

Evolutionary game theory and the adaptive dynamics approach have made invaluable contributions to understanding how gradual evolution leads to adaptation when individuals interact. Here, we review some of the basic tools that have come out of these contributions to model the evolution of...
