The researchers created a model showing how bargaining power within firms can impact employment levels and capital investment.

Interestingly, having strong bargaining power can sometimes lead to too much investment in physical capital. Overall, the study shows that internal dynamics within companies can have significant effects on wages, employment, and investment decisions.
