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

## Location:

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)

## Location:

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"

## Location:

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

## Location:

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