This paper sheds light on the questions, Why does knowledge spill over? and How does knowledge spill over? The answer to these questions lies in the incentives confronting scientists to appropriate the expected value of their knowledge considered in the context of their path-dependent career...

If entrepreneurs are liquidity constrained and cannot borrow to operate on an efficient scale, those with more personal wealth should do better than those with less wealth. We investigate this hypothesis using a unique datset from Norway. Consistent with liquidity constraints being present, we...

What determines the quality of entrepreneurs? To address this question, the paper proposes a simple model of the interaction between individual workers’ decision to become entrepreneurs and established firms’ effort to keep their best workers and ideas. The main prediction from the model is...

We study how complementarities and intellectual property rights affect the management of knowledge workers. The main results relay when a firm will wish to sue workers that leave with innovative ideas, and the effects of complementary assets on wages and on worker initiative. We argue that firms...

We develop a theory of innovation for entry and sale into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Preemptive acquisitions by incumbents are shown to stimulate the...

We claim that the stock market encourages business creation, innovation, and growth by allowing the recycling of ‘informed capital’. Due to incentive and information problems, start-ups face larger costs of going public than mature firms. Sustaining a tight relationship with a monitor (bank,...

This paper provides a theory of venture capital financing based on the complementarity between the financing and advising roles of venture capitalists. We examine the interaction between the staging of investment that characterizes young firms with a high growth potential and the double-sided...

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces effort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a...

We present and analyse an optimizing model which explains the counter-intuitive effects of fiscal policy in terms of expectations. If government spending follows an upward-trending stochastic process, which the public believes may fall sharply when it reaches specific `target points', then...
