There has been increasing interest in understanding how firms undertake non-price adjustment activities, especially in situations where prices may be rigid despite changes in market conditions. Using scanner price data for over 4500 different food products from a large US supermarket chain, we document periods of rigidity in product additions and deletions: new products are less likely to be in...

We study the relation between the stability of a competitive equilibrium (CE) and the price adjustment mechanism used to attain that equilibrium point. Using two specific examples, a three-commodity exchange economy with a unique competitive equilibrium (Scarf’s global instability example) and a two-commodity, two-trader type exchange economy with multiple competitive equilibria, we show that t...

The pure exchange model is the foundation of the neoclassical theory of value, yet equilibrium predictions and models of price adjustment for this model remained untested prior to the experiment reported in this paper. With the exchange economy replicated several times, prices and allocations converge sharply to the competitive equilibrium in continuous double auction (CDA) trading. Convergence...

On the basis of domestic and foreign workers’ study, this paper considers the dynamic model of a duopoly price game in insurance market. In the duopoly model, we theoretically analyze the existence and stability of the Nash equilibrium point of the dynamic system, when one player or both players make a delayed decision, then stability conditions are obtained. The numerical simulation results fu...

Abstract: Using transaction level data for dwellings in Paris, France over the period 1986-92, we find evidence consistent with the hypothesis that economic fundamentals constrain movements in Parisian dwelling prices over longer term horizons. The conclusion is based on the results of two different procedures for estimating an error correction model of housing prices based on supply and demand...
