This paper explores the role of portfolio constraints in generating multiplicity of equilibrium. We present a simple financial market economy with two goods and two households, households who face constraints on their ability to take unbounded positions in risky stocks. Absent such constraints,...

This paper investigates a fund manager's risk-taking incentives induced by an increasing and convex fund-flows to relative-performance relationship. In a dynamic portfolio choice framework, we show that the ensuing convexities in the manager's objective give rise to a finite risk-shifting range...

Recent anti-trust cases exacerbated the concerns of investors regarding the effects of a firm's monopoly power on its production choice, shareholder value, and the overall economy. We address this issue within a dynamic equilibrium model featuring a large monopolistic firm whose actions not only...

In this paper we contrast the main workhorse model in asset pricing theory, the Lucas (1978) tree model (LT-Model), to a benchmark model in financial equilibrium theory, the real assets model (RA-Model). It is commonly believed that the two models entail similar conclusions since the LT-Model is...

We study the impact of evaluating the performance of asset managers relative to a benchmark portfolio on firms' investment, merger and IPO decisions. We introduce asset managers into an otherwise standard asset pricing model and show that firms that are part of the benchmark are effectively...

We argue that the pervasive practice of evaluating portfolio managers relative to a benchmark has real effects. Benchmarking generates additional, inelastic demand for assets inside the benchmark. This leads to a “benchmark inclusion subsidy:” a firm inside the benchmark values an investment...

Money managers are rewarded for increasing the value of assets under management, and predominately so in the mutual fund industry. This compensation scheme gives the manager an implicit incentive to exploit the well-documented positive fund-flows to relative-performance relationship by...
