Many social interactions happen indirectly via modifications of the environment, e.g. through the secretion of functional compounds or the depletion of renewable resources. Here, we derive the selection gradient on a quantitative trait affecting dynamical environmental variables that feed back on...

The number of index funds increased drastically from 2000 to 2020, partially fueled by the emergence of exchange-traded funds (ETFs). Despite the growing availability of similar products, price dispersion persists, with many expensive funds still available, indicating significant market power among...

We argue that the phases identified in the novelty-seeking model can be clarified by considering an updated version of the optimal-level of arousal model, which incorporates the "arousal" and "mood changing" potentials of stimuli and contexts. Such a model provides valuable insights into what...

This paper studies the relationship between air transportation, tourist _ows, and subsidies to Low Cost Carriers (LCCs), a policy used by many national and local governments to stimulate tourist arrivals. To test the policy empirically, we use a two-stage empirical model. In the _rst stage, we...

This paper studies the impact of Higher Order Belief (HOB) shocks, representing shifts in agents’ beliefs about others’ beliefs, on macroeconomic outcomes. The dynamic causal effects of these shocks are identified by leveraging a combination of a proxy-VAR approach and DSGE-based instruments. Our...

We explore the diversification of an urban economy where the labor specialization choices of its residents determine the city’s exposure to sectoral shocks. The presence of demand-driven externalities introduces the possibility of city-wide coordination failures. Residents, when making their...

We provide an algorithm for solving multidimensional screening problems which are intractable analytically. The algorithm is a primal-dual algorithm which alternates between optimising the primal problem of the surplus extracted by the principal and the dual problem of the optimal assignment to...
