Toward a theory of Bayesian experimentation in early‐stage ventures
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary The entrepreneurship literature has established the benefits of experimentation but has paid comparatively little attention to its costs. We develop a Bayesian model to illustrate the entrepreneurial choice between direct and experimental entry.
