Realized divergence gauges the distinct realized moments associated with time-varying uncertainty and is tradeable with divergence swaps engineered from delta-hedged option portfolios. Consistently with established notions of symmetry in arbitrage-free option markets, implied divergence...

We investigate what it means for one act to be more ambiguous than another. The question is evidently analogous to asking what makes one prospect riskier than another, but beliefs are neither objective nor representable by a unique probability. Our starting point is an abstract class of...

This paper deals with the use of the CAPM for capital budgeting purposes. Four different measures are deductively drawn from this model: the disequilibrium Net Present Value, the equilibrium Net Present Value, the disequilibrium Net Future Value, the equilibrium Net Future Value. While all of...

This paper deals with the use of the CAPM for investment decisions and evaluations. Four different measures are deductively drawn from this model: the disequilibrium Net Present Value, the equilibrium Net Present Value, the disequilibrium Net Future Value, the equilibrium Net Future Value. It is...

In this paper we investigate a novel approach to dynamic portfolio asset allocation which stands in sharp contrast to the conventional de facto view of Markowitz (1952) diversification. The traditional paradigm stipulates diversification as a partition of wealth amongst the universe of available...

In an environment with stocks and short-term debt, random changes in the risk-reward frontier produce hedging demands for equities, implying that portfolio policies supporting optimal life-cycle consumption are rarely mean-variance efficient. Pursuing optimal life-cycle portfolio policies is...

In this paper, we investigate how the combination of investment choices and weak assumptions regarding utility maximization implicitly define a risk-adjusted performance measure (RAPM). An investment choice comprises how an investment is funded, its risk and return attributes, and its financial...

We present the first step in a program to develop a comprehensive, unified equilibrium theory of asset and liability pricing. We give a mathematical framework for pricing insurance products in a multiperiod financial market. This framework reflects classical economic principles (like utility...

This paper solves the mean-variance-skewness-kurtosis (MVSK) portfolio optimizationproblem using a new approach based on the Dirichlet distribution. To obtain efficient portfolios,we generalize the Dirichlet distribution using the student copula to produce an increasedproportion of portfolios...
