Asymmetry in beef, lamb and pork farm-retail price transmission in Australia
利用1971-1988年月度数据，检验澳大利亚肉类市场中牛肉、羊肉和猪肉价格在不同市场层级间的不对称传递，发现牛肉和羊肉的零售商和批发商存在不对称价格反应，而猪肉则没有。
The hypothesis of asymmetry in price transmission within the Australian meat market is tested using monthly data for beef, lamb and pork prices at different market levels over the period 1971-1988. The results indicate that asymmetrical price response is a strategy used by beef and lamb retailers and wholesalers to adjust to changing input prices, but not by pork retailers and wholesalers. This difference is perhaps unexpected given the similarity in behaviours relating to price levelling in this market, the high cross-price elasticities of demand between these meats, and the relatively greater degree of concentration in the pork market.
