This is my PhD dissertation defended in 1966 at the University of Minnesota and it was never published. It has been cited and used in other researchers work so I now make it available. The problem of optimal resource allocation over time is formulated as an optimal control problem. This is where...

Using a unique money manager database that allows managers to identify their own investment styles, we examine 4,754 non mutual fund value- and growth-oriented portfolios over the period 1999-2003. Consistent with style definitions, we find that on average, growth funds have price-earnings...

This article provides a rigorous asymptotic analysis of long-term growth rates under both proportional and Morton-Pliska transaction costs. We consider a general incomplete financial market with an unspanned Markov factor process that includes the Heston stochastic volatility model and the...

We develop two new methods for calibrating subjective expectations regarding the return generating process (RGP) of financial assets without resorting to noisy realized returns. Using finance professionals' expectations of average and extreme returns, volatilities, and probabilities of stocks...

We use stochastic optimal control-dynamic programming (DP) to derive the optimal foreign debt/net worth, consumption/net worth, current account/net worth, and endogenous growth rate in an open economy. Unlike the literature that uses an Intertemporal Budget Constraint (IBC) or the Maximum...

This study investigates the linkage between portfolio investment and economic growth in 18 developed and 27 developing countries. Furthermore, it compares and analyzes interest-bearing and non-interest-bearing assets and the economic development level. The results of our analysis show that...
