The objective of this work is to analyze the effects of decrease in water subsidies (increase in the price of the water) on various economic sectors in order to promote the conservation of this resource based on the actual price of water. But over the past decades, various subsidizing methods hold the cost of water down. On the other hand, the indiscriminate use of these resources led the gover...

We consider a Hotelling game where a finite number of retailers choose a location, given that their potential consumers are distributed on a network. Retailers do not compete on price but only on location, therefore each consumer shops at the closest store. We show that when the number of retailers is large enough, the game admits a pure Nash equilibrium and we construct it. We then compare the...

Oil price shocks are the major source of economic instability in oil exporting developing countries, including Iran. In this paper a Multi Sector Dynamic Stochastic General Equilibrium model, with emphasis on optimization of oil sector as a producing sector is designed. Furthermore, an optimizing import sector is introduced into the model by considering the price rigidity in imported goods as a...

What explains the central role of dollar in world trade? Will US currency retain its dominant status future? This paper develops a quantitative general equilibrium framework with endogenous choice that can address these questions. Complementarities price setting and input-output linkages across firms generate complementarities making exporters coordinate on same invoicing. The is more likely to...

In this paper, the Bertrand's price competition in the retail duopoly with asymmetric costs is analyzed. Retailers sell substitute products in the framework of the classical economic order quantity (EOQ) model with linear demand function. The market potential and competitor price are considered to be the bifurcation parameters of retailers. Levels of the barriers to market penetration depending...

We develop spatial competition a la Bertrand for barge shipping along a waterway. Equilibrium prices are derived for two variations. For each case, we …rst give the perfectly competitive benchmark (when all modes are priced at marginal cost) before introducing market power on the modes. The paper emphasizes strategic rivalry (and market power) in two dimensions, and, for tractability, we consid...

Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...
