In this paper we use a differential game analysis to study the dynamic strategic interaction between a criminal gang extorting money from local shop- owners and the police force. In particular, we are interested in characterizing which factors are important in determining whether the capital...

This paper considers a differential game model of a simple marketing channel formed of one manufacturer and one retailer. The manufacturer controls the advertising in the brand equity and the wholesale price and the retailer the promotion of the brand and its price to consumer. The paper shows...

The paper investigates the impact of retailer's myopic behavior on the strategies and outcomes of channel members. Myopia means that the retailer disregards the evolution of the state of the system when optimizing her payoff. The channel is formed of a single manufacturer selling her product...

We investigate whether monetary policy defined as an interest rate rule should respond to stock prices fluctuations under the following two criteria: 1) the rule must guarantee a unique equilibrium and 2) the MSV representation of this unique equilibrium must be learnable in the E-stability...

We study the the emergence of multiple equilibria in models with capital and bonds under various monetary and fiscal policies. We show that the presence of capital is indeed another independent source of local and global multiplicites, even under active policies that yield local determinacy. We...

This paper studies a game theoretic model where agents choose between two updating rules to predict a future endogenous variable. Agents rationally choose between these predictors based on relative performance. Conditions for evolutionary stability and stability under learning are found for the...

The paper presents a correctnes proof as well as an implementation in maple of an algorithm to compute the value function of infinite horizon optimal control problems with a single state variable. It proceeds as follows: step1:compute candidates for equilibria(from the HJB); step2:for each...

When the Central Bank sets nominal rates as a a non-decreasing function of the inflation rate to stabilize the economy, that is it uses a Taylor Rule, the zero lower bound on interest rates may result in multiple equilibria and a liquidity trap. However, if fiscal policy is non-Ricardian, or...

This paper derives a complete characterization for the equilibrium properties of a binary choice interaction model with a finite number of agents - in particular the correspondence between the interaction strength, the number of agents, and the set of equilibria. For the class of games...
