Demystifying the Math of the Coronavirus

By: Elon Kohlberg and Abraham Neyman

We provide an elementary mathematical description of the spread of the coronavirus. We explain two fundamental relationships: How the rate of growth in new infections is determined by the “effective reproductive number” and how the effective reproductive number is... View Details

The Cooperative Solution of Stochastic Games

By: Elon Kohlberg and Abraham Neyman

Building on the work of Nash, Harsanyi, and Shapley, we define a cooperative solution for strategic games that takes account of both the competitive and the cooperative aspects of such games. We prove existence in the general (NTU) case and uniqueness in the TU... View Details

Games of Threats

By: Elon Kohlberg and Abraham Neyman

A game of threats on a finite set of players, N, is a function d that assigns a real number to any coalition, S ⊆ N, such that d(S) = -d(N\S). A game of threats is not necessarily a coalitional game as it may fail to satisfy the condition d(Ø) = 0. We show that analogs... View Details

Cooperative Strategic Games

By: Elon Kohlberg and Abraham Neyman

We examine a solution concept, called the “value," for n-person strategic games. In applications, the value provides an a-priori assessment of the monetary worth of a player's position in a strategic game, comprising not only the player's contribution to the total... View Details

The NTU-Value of Stochastic Games

By: Elon Kohlberg and Abraham Neyman

Since the seminal paper of Shapley, the theory of stochastic games has been developed in many different directions. However, there has been practically no work on the interplay between stochastic games and cooperative game theory. Our purpose here is to make a first... View Details

Partial Equilibrium Approach to the Free-Rider Problem

By: Jerry R. Green, Elon Kohlberg and Jean-Jacques Laffont

Groves and others have shown that truthful answers concerning preferences for public goods can be elicited as dominant strategies if appropriate tax-subsidies rules are applied. This paper studies the statistical properties of the total revenues generated by one of the... View Details
