This paper models capital flows in a rich-poor, two-country, two-asset, dual-risk economy with decreasing absolute risk aversion. The first risk is asset-specific. The second is political and dependent; i.e., related to particular asset outcomes. In this framework, the role of wealth in...

In this note we analyze the composition of an optimal portfolio by considering the cumulative conditional expected outcome of two dependent assets. We develop a conditional stochastic dominance relation and show that for any concave von Neumann-Morgenstern utility function, the proportion of...

Purpose – Seeks to analyze the role of population and wealth in determining capital movements between countries. Design/methodology/approach – By applying the Clark-Jokung 50 percent portfolio theorem, considers the specific case of a two country world where the cumulative conditional...

This paper uses the concept of Marginal Conditional Stochastic Dominance and a generalization of the 50% Portfolio Rule to develop a tractable and parsimonious methodology for constructing a second degree Stochastic Dominance (SSD) efficient portfolio from a given, inefficient index. Because the...

This paper develops a model of regulated Brownian motion with an endogenous profit term to analyze the role of regulatory credibility on the stability and productivity of the banking system. We show that when regulatory intervention is perfect and costless, the volatility of the system can be...

This article analyzes the conditions under which any change in a multiplicative background risk induces a more cautious behavior. We give necessary and sufficient conditions under which any change in the multiplicative background risk with respect to the Nth-degree stochastic dominance raises...

This paper explores in a two-period model the economic implications of people’s tendency to underestimate their ability to adapt to age-related health problems. We model this misperception by assuming that the individual underestimates his future subjective health. Under standard assumptions,...

This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in mean-variance-skewness space. A shortage function is defined that looks for possible increases in return and skewness and decreases in variance. Global optimality is guaranteed for...

This note gives the conditions on preferences to guarantee the monotonicity of asset prices when the payoffs of the risky asset change in the sense of the Nth stochastic dominance and with an Nth degree increase in risk. Those conditions are expressed in terms of the sign of the successive...
