An equilibrium model of dynamic oligopoly with assymetric firms, together with explicit functional form assumptions about costs and demand, determines the estimating equations and stochastic structure of the econometric model. This hypothesis is tested against the alternative that no switch took place, so that price and quantity movements were solely attributable to exogenous shifts in the demand and cost functions.en-USWorking Paper
