This research looks at how businesses in transition economies, like Russia, choose whether to have joint ownership or not. They study this choice because complete contracts cannot be made due to various challenges like uncertainties, high enforcement costs, and language differences. They found that in such situations, owning a part of a company can help solve disputes and secure rights. The researchers model different scenarios and show that when managers share ownership, they are more motivated to invest time and money into the business, which can improve its overall performance. In summary, joint ownership can be the best option for some businesses in these economies.
