MARKETING MARGINS IN THE MEAT SECTOR, ENGLAND AND WALES 1978–1987
分析了1978至1987年英格兰和威尔士牛肉、羊肉和猪肉的价格差数据，结合现有利润理论评估当前价格和利润行为特征与早期研究的差异，发现短期行为解释良好，但长期利润影响因素需进一步研究。
The paper presents a basic analysis of price spread data for beef, lamb and pork over the period 1978 to 1987. The results are reviewed in the light of existing margin theory in order to assess how far the characteristics of price and margin behaviour today differ from those highlighted in earlier work. It is concluded that while short run behaviour is well explained, further research is required if we are to fully understand the factors influencing the longer term development of margins in the meat sector.
