Consumer Learning of Product Quality with Time Delay: Insights from Spatial Price Equilibrium Models with Differentiated Products
In this paper, we present spatial price equilibrium network models, both static and adaptive, with differentiated products under perfect quality information for producers and consumers and under quality information asymmetry with consumer learning of product quality with a time delay. The adaptive model with information asymmetry is able to adapt to the uncertainty in consumer learning as well ...
متن کاملSpatial Equilibrium Models with Gams
This document gives a short introduction into Spatial Equilibrium modeling with GAMS. 1. Intertemporal-Spatial Price Equilibrium Solving spatial equilibrium models by mathematical programming is pioneered by [9],[12], [11], and [13]. One of the most basic forms is the transportation problem, also known as the “Koopmans-Hitchcock” model. An example is found in the GAMS model library in trnsport....
متن کاملSensitivity analysis for time dependent spatial price equilibrium problem
We present some sensitivity results for the spatial price equilibrium problem in the case of quantity formulation model and in presence of excess supply and excess demand. The equilibrium conditions that describe the above model are expressed in terms of a time dependent variational inequality. The variational inequality formulation plays a fundamental role in order to achieve the sensitivity r...
متن کاملFormulation and Analysis of a Dynamic Spatial Price Equilibrium Model
The spatial price equilibrium model begins with the Hitchcock-Koopmans transportation problem as described by Dantzig (1963). The data for this model includes a set of suppliers I and a set of markets J , with supplies ai, demands bj, transport costs cij from supplier i to market j. Cast as a planning problem, this linear program seeks a transport schedule which minimizes the cost of supplying ...
متن کاملSpatial Modeling in Transportation II: Railroad Pricing, Alternative Markets, and Capacity Constraints∗
We describe competition over space between a competitive shipping industry (truck-barge) and one with market power (the railroad). The latter prices so as to "beat the competition" in equilibrium, or else at the monopoly price, if that is lower. The monopoly price rises more slowly than do the costs of transportation (freight absorption) if the spatial demand at each point is log-concave. With ...
متن کاملThe P-star Model in Iran (1960-2005)
This paper studies the usefulness of the P-model in the analysis of the behaviour of prices in Iranian economy. The P-model is based on the Quantity of Theory of Money. This model believes that the price level tends to move towards the equilibrium price level. The model uses price gap to forecast inflation, if the equilibrium price is greater than the current price, there is a tendency for the ...
