Linkages between regulated and unregulated markets: the case of milk supply in Kenya
通过分析肯尼亚八家加工厂的液态奶收购数据，发现受监管市场价格上涨反而减少了受监管市场的收购量，原因是价格上涨也刺激了未监管市场的供给增加。
Linkages between the regulated and unregulated dairy markets in Kenya were examined using an econometric model of the fluid milk intake for eight processing plants. Counter-intuitive results were obtained: an increase in the regulated price was significant in decreasing intake in the regulated market, indicating that a price increase in the regulated market also increased price and quantity supplied in the unregulated market. Lagged rainfall was a proxy for available feed and was highly significant in explaining milk intake in the regulated market.
