The theoretical and empirical literature reports that worker co-operatives protect employment better than investor-owned firms (IOFs) do, especially during economic downturns. This paper introduces the new hypothesis that not only worker co-operatives but all cooperative types (e.g. worker, producer, consumer, credit) protect employment better than IOFs do because they all satisfy their members' needs-instead of maximizing shareholder value-by delivering a stable stream of goods and services. A long-standing pattern in needs satisfaction implies constant activity and employment. To substantiate our hypothesis theoretically, we resort to the evolutionary interpretation of the firm as a problem solver and to the literature on organizational resilience. We test the hypothesis using the data released by the Italian Institute of Statistics for all Italian enterprises in the 1996-2008 pre-crisis and 2008-15 crisis periods.Dynamic multifactor partitioning confirms that in Italy, all typologies of co-operatives withstood the crisis better than other business forms did and that co-operatives were affected the least by economic cyclicality and employment loss.
