This note points out the differences between conducting several projects within one big firm (common ownership) and conducting each project within an independent firm (separate ownership).

We show that if sophisticated institutional managers and individual investors perceive tail-risks differently, then a new explanation for the pricing kernel puzzle emerges. We show, by example, that even a tiny difference in tail-risk perception by the two investor types can explain the pricing...

The paper generalizes and refines the Fundamental Theorem of Asset Pricing of Dalang, Morton and Willinger in the following two respects: (a) the result is extended to a model with portfolio constraints; (b) versions of the no-arbitrage criterion based on the bang-bang principle in control...

Let S=(S_t), t=0,1,...,T (T being finite), be an adapted R^d-valued process. Each component process of S might be interpreted as the price process of a certain security. A trading strategy H=(H_t), t= 1,...,T, is a predictable R^d-valued process. A strategy H is called extreme if it represents a...

Risk-averse expected utility maximization implies that the pricing kernel must be a non-increasing function of aggregate wealth. However, empirical research has found that the pricing kernel frequently displays a locally increasing portion in aggregate wealth. This is known as the pricing kernel...

Over-the-counter (OTC) traders cannot pursue the two fundamental objectives of portfolio management, the identification of portfolio market risk and return and its diversification. The result of this major market shortcoming is a complex, systemically risky market disequilibrium. The tradable...

This note presents an easily implemented, inexpensive, private sector innovation, a futures-friendly derivative (FFD) intended to compete with the unnecessarily credit-risky, dealer-traded, over-the-counter (OTC) derivatives, and their clumsy, expensive, government-mandated clearing...
