In this paper, we aim at investigating from a game‐theory perspective whether trade liberalization can promote a collusive two‐way trade. We show that, under Cournot competition, economic integration is anti‐competitive if collusive trade is a possible outcome of the repeated game; under price competition, the likelihood of collusive trade is a necessary but not sufficient condition for trade liberalization to be pro‐competitive. Furthermore, we show that economic integration may increase the scope for collusion irrespective of the firms’ strategic variable. 相似文献

This paper compares the degree of openness to trade of three developed countries markets—the European Union, Japan, the United
States—with that of three middle-income countries, namely Brazil, India, and China. A theoretically consistent protection
measure—the Mercantilistic Trade Restrictiveness Index (MTRI)—is employed to average tariffs at different levels of aggregation.
The computation relies on a comparative static applied general equilibrium model (Global Trade Analysis Project—GTAP) featuring
imperfect competition as well as on the bilateral applied tariffs included in the most recent version of the GTAP database.
Results provide a different picture from what could have been expected given the widely publicized diffusion of preferential
schemes supposedly favoring developing countries exports.

We investigate a horizontally differentiated duopoly in which a public authority can either tax or subsidize firms, in order to induce duopolists to choose the socially optimal locations. The policy proposed here is such that welfare maximization is achieved by directly affecting firms' location without explicitly modifying their price behavior. 相似文献

The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in which expected endowment growth and economic uncertainty are subject to rare jumps. The arrival of a jump triggers the updating of agents' beliefs about the likelihood of future jumps, which produces a market crash and a permanent shift in option prices. Consumption and dividends remain smooth, and the model is consistent with salient features of individual stock options, equity returns, and interest rates. 相似文献

We study the problem of determining the optimal dimension of a work-in-process storage area in a two-line production system with delays and breakdowns. We propose a stochastic model and prove theoretical results that allow us to implement an exact algorithm for the solution of the model. We optimally solve a real instance and carry out a sensitivity analysis to evaluate if the optimal solution is stable when the initial data are perturbed. 相似文献

We consider the credit risk model of Collin-Dufresne and Goldstein (2001). According to this model, the price of a defaultable bond can be efficiently computed using a variational formulation that consists of an integral relation and a Volterra integral equation. In Collin-Dufresne and Goldstein (2001) this integral equation is justified by a probabilistic intuition, but is not proven formally. In this paper we analytically derive the variational formulation used in Collin-Dufresne and Goldstein (2001). This analysis allows to give a correct characterization of the solution of the integral equation. Furthermore the approach proposed in this paper could also be employed for other models of credit risk. 相似文献

Recognizing the inflexibility inherent in standard capital budgeting analysis, recent research has provided new insights using a real options framework. This paper uses the explicit finite difference approach to value real options. However, instead of assuming a constant return and volatility term, we assume that these variables are sensitive to changes in the economic environment. Accordingly, we adapt our approach to incorporate a Markov switching feature. Further, we recognize that some of the modeling assumptions can be violated in a practical application. Therefore, we recommend using range based estimates of the real option value, as opposed to a point estimate. 相似文献
