GAME THEORY AND MATHEMATICAL ECONOMICS RESEARCH SEMINAR:Michal Feldman, Tel Aviv University "Interdependent Values without Single-Crossing (Joint work with Alon Eden, Amos Fiat and Kira Goldner)"

1:30pm to 2:30pm

Location: 

Elath Hall, 2nd floor, Feldman Building, Edmond Safra Campus

Abstract:

We consider a setting where an auctioneer sells a single item to n potential agents with {\em interdependent values}. That is, each agent has her own private signal, and the valuation of each agent is a function of all n private signals. This captures settings such as valuations for oil fields, broadcast rights, art, etc.

Game Theory & Math Economics: Sergiu Hart - "Too Much Two Good To Be True: The Complexity of Auctions"

4:00pm to 6:00pm

Location: 

Elath Hall, 2nd floor, Feldman Building, Edmond J. Safra Campus

We consider the problem of maximizing the revenue from selling a number of goods (or items). In this talk we will focus on approximation results and on the "menu-size" as a measure of auction complexity which affects the revenue. * All the relevant concepts will be introduced in the talk.* The talk is mostly independent of the talk given earlier this year.

Game Theory & Math Economics: Philip J. Reny (University of Chicago) - "Sequential Equilibria of Multi-Stage Games with Infinite Sets of Types and Actions," (joint work with Roger Myerson)

4:00pm to 6:00pm

Location: 

Elath Hall, 2nd floor, Feldman Building, Edmond J. Safra Campus

Guided by several key examples, we formulate a definition of essential sequential equilibrium for multi-stage games with infinite type sets and infinite action sets, and we prove its general existence.

Game Theory & Math Economics: Fuad Aleskerov (National Research University "Higher School of Economics" and Institute of Control Sciences, Moscow) - "Power Distribution: Theory and Applications"

4:00pm to 6:00pm

Location: 

Elath Hall, 2nd floor, Feldman Building, Edmond J. Safra Campus
We discuss a new class of indices taking into account agents'preferences to coalesce.An axiomatization of these indices are presented.These indices are used to evaluate power distribution in Russian parliament in new era and in Empire period, in the Reichstag of Weimar Republic, in IMF, in Russian banks.

Game Theory & Math Economics: Sergui Hart - "Much Too Good To Be True: Lotteries and the Complexity of Auctions"

4:00pm to 6:00pm

Location: 

Elath Hall, 2nd floor, Feldman Building, Edmond J. Safra Campus

We consider the problem of maximizing the revenue from selling a number of goods to a single buyer. In this talk we will focus on the need for randomization (which arises only when there are multiple goods), and on the "menu-size" as a measure of auction complexity which affects the revenue. (All the relevant concepts will be introduced in the talk.)
