Stackelberg game models of security have received much attention, with a number of approaches for computing Stackelberg equilibria in games with a single defender protecting a collection of targets. In contrast, multi-defender security games have received significantly less attention, particularly when each defender protects more than a single target. We fill this gap by considering a multidefe...

We study equilibrium properties of discrete-time, infinite-horizon smooth economies whose equilibria can be represented as a sequence of interrelated equations, and provide sufficient conditions to guarantee existence, (generic) determinacy and (generic) robustness of equilibria. Our approach exploits the sequential nature of a dynamic economy. An equilibrium is represented by a sequence of end...

In this paper we give an elementary introduction into the theory of variational inequalities and their application to general equilibrium analysis. Furthermore we incorporate some results on sensitivity analysis of variational inequalities on polyhe-dral sets.

We analyse an economy where principals and agents match and contract subject to moral hazard. Bankruptcy law defines the limited liability constraint in these contracts. We analyse Walrasian allocations to generate the following predictions: (i) weakening bankruptcy law causes redistribution of debt and welfare from poor agents and principals to rich agents; (ii) exemption limits Pareto-dominat...

We present a structural model of political advertising in equilibrium. Candidates choose advertising across media markets in order to maximize the probability of winning the national election. The voter model takes the form of an aggregate random coefficients discrete choice model in which advertising affects a voter’s incentive to vote for either candidate or not to vote at all. We estimate th...

In this paper, Nash equilibriums of generation markets are investigated using a game theory application for simplified competitive electricity markets. The characteristic of equilibrium states in N-company spot markets modelled by uniform pricing auctions is analyzed and a new method for obtaining Nash equilibriums of the auctions is proposed. Spot markets are assumed to be operated as uniform ...

A composite based on poly(N-vinylpyrrolidone) (PVP) and sodium bentonite was prepared by a simple method. Structural characterizations of the bentonite and the composite were performed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The TGA analysis showed a low loading of the polymer in the bentonite. XRD analysis confirmed a mod...

the objective of this paper is econometric analysis of iranian agricultural products markets (case study ofpotatoes) by using equilibrium and disequilibrium techniques. sections i and ii proceeds by classification of disequilibrium econometric literature and supply and demand analysis for agriculural products, respectively. in the other parts ofpaper potato market lif iran was hypothesized and ...

In this study, we conduct a competitive equilibrium analysis for the repeated (sequential) procurement auctions. We consider capacitated suppliers (bidders), each with a U-shaped cost function that captures the economies (and dis-economies) of scale in bidding quantity. Cases with both homogenous and non-homogenous bidders are considered in a symmetric incomplete information setting. First we a...
