Product quality in the agri-food chain: do cooperatives offer high-quality wine?
研究合作社与投资者所有企业在产品质量上的差异，发现合作社成员有过度生产和搭便车的动机，最终产品质量取决于质量聚合方式和成员数量，奥地利葡萄酒市场的证据表明合作社葡萄酒质量显著较低。
We investigate the impact of decentralised decision-making on product quality. Comparing a cooperative and an investor-owned firm suggests that members of the cooperative have an incentive to produce too much and to free-ride on quality. Whether or not cooperatives deliver higher quality products depends on the way in which the quality of the final product is determined from the quality levels of the inputs delivered (quality aggregation) as well as the number of members of the cooperative. Empirical evidence on the Austrian wine market suggests that wines produced by cooperatives tend to be of significantly lower quality, ceteris paribus.
