Robust Equilibria in Location Games

Buechel, Berno; Roehl, Nils - Fachbereich für Wirtschaftswissenschaften, … - 2013

In the framework of spatial competition, two or more players strategically choose a location in order to attract consumers. It is assumed standardly that consumers with the same favorite location fully agree on the ranking of all possible locations. To investigate the necessity of this...

Temporal graphs

Kostakos, Vassilis - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 6, pp. 1007-1023

We introduce the idea of temporal graphs, a representation that encodes temporal data into graphs while fully retaining … number of metrics that can be used to study and explore temporal graphs. Finally, we use temporal graphs to analyse real …

All Solution Graphs in Multidimensional Screening

Kokovin, S.; Nahata, B.; Zhelobodko, E. - In: Journal of the New Economic Association (2011) 11, pp. 10-38

We study general discrete-types multidimensional screening without any noticeable restrictions on valuations, using instead epsilon-relaxation of the incentivecompatibility constraints. Any active (becoming equality) constraint can be perceived as "envy" arc from one type to another, so the set...

Graphical representation of multivariate data using Chernoff faces

Raciborski, Rafal - In: Stata Journal 9 (2009) 3, pp. 374-387

Chernoff (1971, Technical Report 71, Department of Statistics, Stan- ford University; 1973, Journal of the American Statistical Association 68: 361– 368) proposed the use of cartoon-like faces to represent points in k dimensions. This article describes a Stata implementation of a...

Organizing Contests for Status: The Matthew Effect vs. the Mark Effect

Bothner, Matthew S.; Podolny, Joel M.; Smith, Edward Bishop - In: Management Science 57 (2011) 3, pp. 439-457

What is the best way to design tournaments for status, in which individuals labor primarily for the esteem of their peers? What process, in other words, should organizers of status-based contests impose upon those who covet peer recognition? We propose a formal model of status-based competition...

Price Competition on Graphs

Soetevent, Adriaan R. - Tinbergen Institute - 2010

This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I … existence result of D'Aspremont et al. (1979) does not extend to simple star graphs. I conjecture that this non-existence result …

Information-sharing in social networks

Kleinberg, Jon; Ligett, Katrina - In: Games and Economic Behavior 82 (2013) C, pp. 702-716

We present a new model for reasoning about the way information is shared among friends in a social network and the resulting ways in which the social network fragments. Our model formalizes the intuition that revealing personal information in social settings involves a trade-off between the...
