This paper applies to the static hedge of barrier options a technique, mean-square hedging, designed to minimize the size of the hedging error when perfect replication is not possible. It introduces an extension of this technique which preserves the computational efficiency of mean-square...

We develop a model of insider trading where agents have private information either about liquidation value or about supply and behave strategically to maximize their profits. The supply informed trader plays a dual role in market making and in information revelation. This trader not only reveals...

This paper investigates the testable restrictions on the time-series behavior of equity premia implied by a representative agent model whose state- and time-non separable preferences are subject to taste shocks. The model nests state- and time-separable preferences with and without taste shocks...

This paper adopts the Fama and French (1993) methodology for determining the common risk factors in the returns of Canadian stocks. Our results suggest that the three stock market factors, the excess stock market returns, a size factor, and a book-to-market equity factor, explain most of the...

Why did the stock market decline so much in the early 1970s and remain low until the early 1980s? We argue that it was because information technology arrived on the scene and the stock-market incumbents of the day were not ready to implement it. Instead, new firms would bring in the new...

The first contribution of this paper, following the works of Lettau and Ludvigson (2001a,b), is construction of the Japanese consumption-wealth ratio data series and to examine whether it explains Japanese stock market data. We find that the consumption-wealth ratio does not predict future stock...

In this study, we employ an innovative new methodology inspired from the approach of Hwang and Salmon (2004) and based on the cross sectional dispersion of trading volume to examine the herding behavior on Toronto stock exchange. Our findings show that the herd phenomenon consists of three...

Modelling stock return generating process as a single factor model, we show analytically that the relation between idiosyncratic volatility measured as variance of the residuals and expected stock return in the cross-section may be represented by a parabola that opens to the left and has...

During the last years the problem of card fraud expanded dramatically due to the growth of numbers of users, the increase number of ATM or POS transaction, internet or mobile payments. Together with this, the criminals become more sophisticated and the impact of losses generated by their actions...
