Price and quantity adjustment in a dual character market The case of the Greek poultry sector
构建了一个包含垄断竞争和完全竞争两个细分市场的短期模型，估计了希腊家禽业的需求和供给弹性以及价格与数量的调整速度，发现调整非常迅速且数量调整快于价格。
ABSTRACT 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.
