Price and quantity adjustment in a dual character market: The case of the Greek poultry sector
构建并检验了希腊家禽业的短期模型，该模型允许垄断竞争和完全竞争两个市场同时存在，并估计了价格和数量的调整速度，发现数量调整快于价格。
In this paper we set up, estimate and test a short-run model for the poultry sector in Greece. The model allows for the simultaneous existence of a monopolistically competitive and a competitive segment, and determines producer and consumer prices, and the quantity consumed. We provide evidence on steady-state parameters such as demand and supply elasticities, as well as on speeds of adjustment of prices and quantities. The evidence suggests that adjustment is very rapid, although quantities appear to be adjusting more quickly than prices. The model is used to examine the dynamics of adjustment to demand and supply-side disturbances.
