KALASHNIKOVand KALASHNYKOVA: SIMULATION OF A CONJECTURAL VARIATIONS
نویسندگان
چکیده
In this paper, we have extended previously known human migration models and realized a series of numerical experiments on a model example to simulate the influence of the marginal migration costs, utility function values and the influence coefficients on the equilibrium states. The introduced influence coefficients allow one to consider and study not only the two classical models by Walras (perfect competition model) or Cournot-type ones in application to the human migration problem, but also the whole series of intermediate models determined by different forms of conjectural influence quotients. Moreover, to increase the flexibility of the proposed scheme, we allow the conjectural influence quotients to take distinct values at the original location and at the destination.

Partially Mixed Duopoly and Oligopoly: Consistent Conjectural Variations Equilibrium (CCVE). Part 2
In this paper, a model of partially mixed oligopoly with conjectured variations equilibrium (CVE) is studied. The agents make conjectures concerning the price variations depending upon their production output’s fluctuations. Existence and uniqueness results for the conjectured variations equilibrium (called an exterior equilibrium) is established for any collection of feasible conjectures. To d...

In this paper, we consider a model of partially mixed duopoly with conjectured variations equilibrium (CVE). The agents’ conjectures concern the price variations depending upon their production output’s increase or decrease. We establish existence and uniqueness results for the conjectured variations equilibrium (called an exterior equilibrium) for any set of feasible conjectures. To introduce ...
متن کاملSpot Price Simulation and Volatility Analysis in the Future Iberian Electricity Market
Price volatility is a major issue in liberalized electricity markets as far as risk management is concerned. In this paper we evaluate the impact of the Portuguese and Spanish electricity markets integration on the day-ahead market price volatility. For that purpose we develop an adaptive conjectural variations model which is implemented in GAMS language. We estimate the degree of competition i...
متن کاملOligopoly and consistent conjectural variations
This article examines "consistent" conjectural variations in an oligopoly model with a homogeneous product. A conjectural variation is consistent if it is equivalent to the optimal response of the otherfirms at the equilibrium defined by that conjecture. When the number of firms is fixed, we find that competitive behavior is consistent when marginal costs are constant, but that when marginal co...
متن کاملConjectural variations and evolutionary stability: A new rationale for consistency∗
Adopting an evolutionary approach, we explain the conjectural variations Þrms may hold in duopoly. Given conjectures, Þrms play the market game rationally. Success in the market game determines Þtness in the evolutionary game. We show that the unique conjectures which are evolutionarily stable are consistent in that they anticipate rivals behavior correctly.
