Efficiency of Investor Owned Firms and Cooperatives Revisited

Providing a performance measure of any firm is a crucial issue, not only for the stakeholders of the firm, but also for policy makers, labor unions, and economists. The relevant performance measures should consider the objectives of the firm’s owners. The ownership structure of cooperatives is different from that of investors owned firms, which in principle implies the need of different tools to measure their performance. Typically, however, the performance of cooperatives and investor owned firm is mostly compared using the same approach. In this study, we use Data Envelopment Analysis (DEA) to compare the performance of dairy cooperatives and investor owned firms in major European dairy producing countries using a traditional approach, which views both types of firms as cost minimizers, and an alternative approach, which considers the objectives of the cooperatives. In the alternatives approach, two hyperbolic models were evaluated, one of them consider the firms to expand both output production and use of material to address the objective of the owners of the cooperatives. The performance of the cooperatives changes across the two approaches form being out performed by IOFs using the traditional approach to outperforming IOFs when using an approach that is in line with the objective of the cooperative
