When regulating the financial system, the volatility phenomenon seems to emerge, practically, as a phenomenon which is intrinsic to the capital market behaviour. Theoretically, the leverage of the firms appears to be a major determinant of the volatility of prices and returns. At the same time,...

Mullainathan et al [Quarterly Journal of Economics, May 2008] present a model of coarse thinking or analogy based thinking. The essential idea behind coarse thinking is that people put situations into categories and the values assigned to attributes in a given situation are affected by the...

This study is the first attempt to investigate the relationship between firm’s leverage and systematic risk for seven European countries in relation to Shari’ah (Islamic) stock screening. This paper also aims to examine the shock transmission through the systematic risk and whether less debt...

A major issue facing the investors in the financial markets of the contemporary world is to identify whether the observed stock market fluctuations are due mainly to contagion or fundamentals. This is due to the fact that if the fluctuations are mainly due to a contagion, then it is something...

In theory, the price of equity is determined by the dividend yields and growth potentials of the firms. There exists established empirical proof of the impact of macroeconomic changes to the equity markets. With the advent of Islamic equities, and the recent surge of interest in them have raised...

Our study measures co-movements in Islamic and conventional equity markets, to discover contagion and to measure integration level. We apply wavelet decomposition to unveil the multi-horizon nature of co-movement. We find that the subprime crisis generates fundamental-based contagion for both...

An anchoring adjusted currency option pricing formula is developed in which the risk of the underlying currency is used as a starting point which gets adjusted upwards to arrive at the currency call risk. Anchoring bias implies that such adjustments are insufficient. The new formula converges to...

Here, we show that agents who are ex ante rational, if allowed to interact locally, may generate clustering of volatility. Hence, there is no need to reject the notion of rationality in agent based models.

Mullainathan et al [Quarterly Journal of Economics, May 2008] present a formalization of the concept of coarse thinking in the context of a model of persuasion. The essential idea behind coarse thinking is that people put situations into categories and the values assigned to attributes in a...
