In an economy where interest rates and stock price changes follow fairly general stochastic processes, we analyze the portfolio problem of an investor endowed with a non-traded cash bond position. He can trade on stocks, the riskless asset and a futures contract written on the bond so as to maximize the expected utility of his terminal wealth. When the investment opportunity set is driven by an...

We show that the endogenous stochastic process of the liquidity of securities is as important to investment and valuation as the exogenous stochastic process of their cash ‡ows. We develop a general-equilibrium model with heterogeneous investors who have an every-day motive to trade and pay transactions fees. Our model delivers the optimal, market-clearing moves of each investor and the resulti...

We study the properties of unconditional minimum-variance portfolios in the presence of conditioning information. Such portfolios attain the smallest variance for a given mean among all possible portfolios formed using the conditioning information. We provide explicit solutions for n risky assets, either with or without a riskless asset. Our solutions provide insights into portfolio management ...

Dyslexia is a selective impairment of reading and spelling abilities without a deficit in general intelligence. Dyslexia is commonly attributed to a phonological deficits (e.g., Ramus, Rosen, Dakin, Day, Castellote, White & Frith, 2003). However, a mild cerebellum dysfunction (Nicolson, Fawcett & Dean, 2001) and specific visual problems, such as a defective magnocellular system, have also been ...

The distal-convoluted tubule (DCT) of the kidney absorbs NaCl mainly via an Na -Cl cotransporter located at the apical membrane, and Na , K ATPase at the basolateral side. Cl transport across the basolateral membrane is thought to be conductive, but the corresponding channels have not yet been characterized. In the present study, we investigated Cl channels on microdissected mouse DCTs using th...

An ozonization system (Ozomax OZO 6VTT, IGT limited, Ontario, Canada) was installed in a commercial plastic-covered greenhouse in Danville, Quebec, Canada (www.savoura.com) to study the effects of the disinfection and recirculation of the nutrient solution in a tomato crop. The ozonization system was compared to a conventional growing system where the nutrient solution was not treated, neither ...
