Despite the importance of expectiles in fields such as econometrics, risk management, and extreme value theory, expectile regression unfortunately so far remains limited to single-output problems. To improve on this, we define hyperplane-valued multivariate expectiles that show strong advantages...

Investment in wind power has grown remarkably in the past decades in Portugal. Although economic development is an argument for investment incentive policies, little evidence exists as to their net impact on local-level unemployment. Using a panel of all 278 Portuguese mainland municipalities for...

We study the effects of property rights over the use of data on market outcomes. To do so, we consider a model in which a monopolistic firm offers a service to a set of heterogeneous users. The use of the service generates valuable data, but data extraction entails a privacy cost for users. A trade...

The traditional quantification of free motions on Euclidean spaces into the Laplacian is revisited as a complex intertwining obtained through Doob transforms with respect to complex eigenvectors. This approach can be applied to free motions on finitely generated discrete Abelian groups: ℤm, with m...

We study platform markets in which the information about users' preferences is dispersed. First, we show how the dispersion of information introduces idiosyncratic uncertainty about participation decisions and how the latter shapes the elasticity of the demands and the equilibrium prices. We then...

We show that experience good sellers facing myopic buyers can solve the inherent moral hazard problem by communicating their observation of quality before trade, provided that communication is part of their public track record. Such cheap-talk communication, if trusted, allows market prices to...

Social norms comparisons are tools that are being used more and more often by energy and water utilities all over the world in order to induce households to conserve resources. Such conservation programs are appealing to utilities since they are an easy-to-implement alternative to raising prices...

To internalize pollution externalities into household waste generation, Unit Pricing Systems (UPS) have been adopted worldwide. This paper evaluates the causal effects of a UPS on the disposal of municipal solid waste in Trento, Italy. Using a unique panel dataset of monthly waste generation in...

Humans and other animals appear to defy many principles of economic ‘rationality’ when making decisions. Here, we use an ecological rationality framework to examine patterns of decision-making across species to illuminate the origins of these strategies. We argue that examples of convergent...

Long-lasting, romantic partnerships are a universal feature of human societies, but almost as ubiquitous is the risk of instability when one partner strays. Jealous response to the threat of infidelity is well studied, but most empirical work on the topic has focused on a proposed sex difference in...
