We model the payments to workers using the normatively appealing Nash bargaining solution. We analytically characterize the equilibrium effort levels of workers and describe the conditions under which a full‐fledged final product (as opposed to, say, a prototype) is developed. We also provide an answer to the firm's problem of optimal incentive provision.EnglishArticle10.1002/mde.3266
