This study mainly analyzes the market power between egg
producers and marketers for chicken-egg market in Taiwan. This
study may contruibute to understanding the reasonable egg
pricing and to being the foundation of planning the egg
marketing system. The important findings of this study are
summarized as following: 1. To test the power between chicken-
egg marketing stages by using the intermediate input price
approach as the theoretical basis, and to fit with ARCH(
autoregressive conditional heteroscedasticity)model as the
estimation method.The results are the wholesalers and the
jobbers exert monopsony power to producers, and exert monopoly
power to retailers. 2. According to the asymmetry tests for
margin with response to the price transmission,wholesalers get
more profits with the farm-price decrease, while both
wholesalers and jobbers benifit from the wholesale-price
increase or decrese. Marketing margins with responses to the
price changes are asymmetric.This showed that the marketers
made a profit by the pricing system and the lag information. 3.
Caculating the theoretical margin of the traditional channel,「
producer-wholesaler-jobber-retailer」, was done by using the
cross-section data of 1991 in perfect competitive market. The
margin distribution being「1.25-1.53-2.15 NT$/0.6kg」,which the
total margin is 4.93 NT$/0.6kg , differs from the margin
distribution being「2.50-2.50-2.00 NT$/0.6kg」, which the total
margin is 7 NT$/0.6kg setting by Marketer-Egg Association. The
implications drawn from this study are that one is to give an
attention to adjusting the market structure, the other is to
concern with improving the marketing efficiency and with
changing the distribution of the marketing margin for chicken-
egg market in Taiwan.
