The paper begins by providing historical evidence concerning the resilience of co-operatives during economic crises. Then, taking a 'member-owned business' approach, it analyses the comparative advantages and disadvantages of co-ops along three dimensions: ownership, control and benefit. It broadens this out to consider advantages to the wider society, and theorises comparative advantages of other business types. It concludes by asking what it would take for the co-operative potential to be realized. The potential of co-operatives during the current recession; theorizing comparative advantage Birchall, J.
