We study a competition model with two sellers that auction non-identical objects, unlike most of the literature on competing auctions. Each bidder has bidimensional private information, his values for the objects, and chooses the auction in which he participates (if any) after each seller has...

As in [7] we consider classical system of interacting particles P_1, ... , P_n on the line with only neighboring particles involved in interaction. On the contrast to [7] now periodic boundary conditions are imposed onto the system, i.e. P_1 and P_n are considered neighboring. Periodic Toda...

We study classical multiparticle system (e.g. Toda lattice) on the line whose dynamics will be controlled by forces applied to few particles of the system. Various problem settings, typical for control theory are posed for this model; among those: studying accessibility and controllability...

We study controllability of 2D defocusing cubic Schroedinger equation under periodic boundary conditions and control applied via source term (additively). The source term is a linear combination of few complex exponentials (modes) with time-variant coefficients - controls. We manage to prove...

We consider a signalling game in which a population of receivers decide on the outcome by majority rule, sender and receivers have conflicting interests, and there is uncertainty about both players’ types. We model players rationality along the lines of recent findings in behavioral game...

We consider a deterministic evolutionary model where players form expectations about future play. Players are not fully rational and have expectations that change over time in response to current payoffs and feedback from the past. We provide a complete characterization of the qualitative...

In this study, we analyze the career profiles of Italian politicians in the post-war period. Using a unique, newly collected data set that contains detailed information on all the politicians who have been elected to the Italian Parliament between 1948 and 2008, we address a number of important...

We present a spatial map of the Italian House during the XIII Leg-islature obtained by applying the Poole and Rosenthal methodology to roll call data. We obtain coordinates for almost all the 650 MPs that were on the House's °oor at the time, and we aggregate them according to parties. We ¯nd...

We consider a (deterministic) evolutionary model where players have dynamic expectations about the strategy distribution. We provide a global analysis of the co-evolution of play and expectations for a generic two{by{two game. Besides the the typical indeterminacy of the evolutionary dynamics,...
