Academics and regulators have given significant attention to the impact of institutional investors on the companies in which they invest. Some are concerned that the institutional investors act as common owners. But in their active ownership policies institutional investors often say they are...

Tension between efficiency and equity is fundamental to every economy. Historical differences between groups translate into inequality in skills and hence earnings. Measures to correct inequalities affect incentives and misallocate talent, therefore compromising efficiency. This paper examines...

Does competitive pressure foster innovation? In addressing this important question, prior studies ignored a distinction between discrete innovation aiming at entirely new technology and continuous improvement consisting of numerous incremental improvements and modifications made upon the...

We look at imperfectly competitive markets where some consumers might be budget constrained. The set of budget constrained consumers varies endogenously with price. While the presence of such consumers reduces aggregate demand, we find that the equilibrium price under budget constrained demand...

When firms form an alliance, it often involves one firm acquiring an equity stake in its alliance partner. Such an alliance weakens competition, but induces knowledge transfer between partner firms. We explore oligopoly models that capture the link between knowledge transfer and partial equity...

We study welfare effects of horizontal mergers under a successive oligopoly model and find that downstream mergers can increase welfare if they reduce input prices. The lower input price shifts some input production from cost- inefficient upstream firms to cost-efficient ones. Also, the lower...
