Industries with more complex input-output relationships are comparatively larger in U.S. states with higher levels of trust. This specialization pattern is not driven by differences in the states' and industries' other observable characteristics. Given the importance of complexity in economic...

In rank aggregation, members of a population rank issues to decide which are collectively preferred. We focus instead on identifying divisive issues that express disagreements among the preferences of individuals. We analyse the properties of our divisiveness measures and their relation to existing...

We construct a Nash equilibrium in feedback form for a class of two-person stochastic games with absorption arising from corporate finance. More precisely, the paper focusses on a strategic dynamic game in which two financially-constrained firms operate in the same market. The firms distribute...

We propose to study Compositional Data (CoDa) from the projec-tive geometry viewpoint. Indeed, CoDa, as equivalence classes of propor-tional vectors, corresponds to projective points in a projective space, and thus can be studied using the tools, language and framework of projec-tive geometry....

We consider models for network-indexed multivariate data, also known as graph signals, involving a dependence between variables as well as across graph nodes. The dependence across nodes is typically established through the entries of the Laplacian matrix by imposing a distribution that relates the...

Nature exhibits rapid evolution in response to human activities. When using natural resources for their own profit, humans should account for such responses. Stackelberg evolutionary games (SEG) offer a method for modeling interactions between a rational leader (humans) and evolutionary followers (...

We analyze the effect of media mergers in a model that stresses, on the one hand, the fact that media are two-sided platforms willing to attract advertisers and viewers and, on the other hand, that strong competitors have emerged to challenge traditional media on both sides. We show that a merger...
