In this research we investigate how magnitude and direction of resource flows between a firm and its alliance portfolio as well as the complementary nature of resources affect firm performance. Building on the resource dependence theory, we develop and test arguments on a sample of 59 firms in...

This paper proves a class of static fund separation theorems, valid for investors with a long horizon and constant relative risk aversion, and with stochastic investment opportunities. An optimal portfolio decomposes as a constant mix of a few preference-free funds, which are common to all...

We derive the process followed by trading volume, in a market with finite depth and constant investment opportunities, where a representative investor, with a long horizon and constant relative risk aversion, trades a safe and a risky asset. Trading volume approximately follows a Gaussian,...

This paper addresses management of sovereign wealth from the perspective of the theory of contingent claims. Starting with the sovereign's balance sheet, we frame sovereign fund management as an asset-liability management (ALM) problem, covering all public entities and taking explicit account of...

Recent progress in portfolio choice has made a wide class of problems involving transaction costs tractable. We review the basic approach to these problems, and outline some directions for future research

Student investment funds are currently in operation globally at many large business schools and even small liberal arts colleges. Their management follows a wide variety of processes, from unsupervised to highly professional. While all investment managers labor to deliver alpha in a diversified...

This paper sets out a new approach to sovereign wealth and risk management, based on the theory of contingent claim analysis (CCA). To manage sovereign risk, it is essential to analyse the sovereign's balance sheet. The state has to solve an asset-liability management (ALM) problem between its...
