This paper analyzes whether the market portfolio is efficiently related to benchmark portfolios formed on size, value, momentum and reversal with various utility theories by using stochastic dominance criteria. The results support the prospect theory including assumption of loss aversion at...

We model how investors allocate between asset managers, managers choose their portfolios of multiple securities, fees are set, and security prices are determined. The optimal passive portfolio is linked to the “expected market portfolio,” while the optimal active portfolio has elements of...

Effective risk management is an important aspect of farming. Risk management involves choosing among alternatives that reduce the financial effects of the uncertainties of weather, yields, prices, government policies, and other factors that can cause wide swings in farm income. To deal with...

We consider competition among n sellers when each of them sells a portfolio of distinct products to a buyer having limited slots (or shelf space). We study how bundling affects competition for slots. When the buyer has k number of slots, efficiency requires the slots to be allocated to the best...

Investors seek to hedge against interest rate risk by taking long or short positions on bonds ofdifferent maturities. We study changes in risk taking behavior in a low interest rateenvironment by estimating a market stochastic discount factor that is non-linear and thereforeconsistent with the...

We study negative interest rate policy (NIRP) exploiting ECB's NIRP introduction and administrativedata from Italy, severely hit by the Eurozone crisis. NIRP has expansionary effects on credit supply---and hence the real economy---through a portfolio rebalancing channel. NIRP affects banks...

We show that the quotient of Levy processes of jump-diffusion type has a fat-taileddistribution. An application is to price theory in economics, with the result that fat tails ariseendogenously from modeling of price change based on an excess demand analysis resulting in aquotient of arbitrarily...

Credit Value Adjustment (CVA) has been one of the "hot topics" in the financial industry since 2009. There have been several papers on the subject and the topic has been widely discussed in all banking conferences around the world. However, often, the fundamentals of this topic have been...

Although the relationship between oil prices and exchange rates has been investigated extensively in the literature, the results remain mixed. The aim of this article is to revisit this relationship allowing for nonlinear dynamics in the speed of adjustment to the equilibrium. This article...

We merge administrative information from a large German discount brokerage firm with regional data to examine if financial advisors improve portfolio performance. Our data track accounts of 32,751 randomly selected individual customers over 66 months and allow direct comparison of performance...
