A small monthly macroeconometric model of the Canadian economy built around three cointegrating relationships linking financial and real variables is estimated over the 1975-2002 period. One of the cointegrating relationships allows the identification of a supply shock as the only shock affecting permanently the stock market and a demand shock leading to important transitory stock market overva...

With greater penetration of renewable generation, the uncertainty faced in electricity markets has increased substantially. Conventionally, generators are assigned a pre-dispatch quantity in advance of real time, based on estimates of uncertain quantities. Expensive real time adjustments then need to be made to ensure demand is met, as uncertainty takes on a realization. We propose a new stocha...

Forskolin, magnesium, homotaurin, L-carnosin, vitamins B1, B2, B6 and folic acid are the main ingredients of a food supplement commercially available. This drug contributes to a small reduction of IOP in glaucomatous patients who are poorly responsive to multitherapy treatment. The aim of this study is to evaluate a possible change of visual field and pattern-electroretinogram (PERG) parameters...

Volatility in monthly international tourist arrivals is defined as the squared deviation from mean monthly international tourist arrivals. Consequently, volatility is directly related to the standard deviation, which is a common measure of financial risk. Fluctuating variations, or conditional volatility, in international monthly tourist arrivals are typically associated with unanticipated even...

The non-normality of financial asset returns has important implications for hedging. In particular, in contrast with the unambiguous effect that minimum-variance hedging has on the standard deviation, it can actually increase the negative skewness and kurtosis of hedge portfolio returns. Thus the reduction in Value at Risk (VaR) and Conditional Value at Risk (CVaR) that minimum-variance hedging...
