We show by explicit closed form calculations that a Hurst exponent H≠1/2 does not necessarily imply long time correlations like those found in fractional Brownian motion. We construct a large set of scaling solutions of Fokker-Planck partial differential equations where H≠1/2. Thus Markov...

The effect of options’ introduction on underlying market is one of the frequently debated themes in financial research. A significant body of literature addresses the question of effects of options’ introduction. The critical review of the literature shows that there is no consensus among...

We investigate if using a CPPI-style methodology it is possible to “improve” the distribution of portfolio returns from the point of view of an investor holding a balanced portfolio with different allocations in Equities, and whose concern is to avoid significant negative returns and in...

In this paper we examine the effects of media coverage of commodity prices increases and decreases on the price of the commodity and how media coverage in other commodities affects prices. We provide evidence of the relationship between media coverage and its intensity to the price level of...

This paper aims to explore the relevance of the Asymmetric Information and the Theory of Argumentation TA in the complex area of financial crises. Specifically, we investigated the scope of the phenomenon of persuasion in advertising. It examines advertisements in publications notable economic...

This paper investigates the relationship between sovereign and bank CDS spreads with reference to their ability to convey timely signals on the default risk of European sovereign countries and their banking systems. By using a sample of six major European economies, we find that sovereign and...

This paper is aimed at highlighting how common law has evolved over the centuries, namely through the flexibility accorded to judicial precedents, as well as through the evolutionary nature evidenced in the processes and rules applied in statutory interpretation. In addition to illustrating how...

This paper carried out two main studies: Part 1 attempted to conduct a set of tests for weak form efficiency (WFE); Part 2 tried to estimate day of the week effect using GARCH and EGARCH models. The principal objective of this paper, hence, is to test the weak-form efficiency for selected three...

Since the global financial crisis that crippled the world’s financial markets in 2007, interest in nonlinear dynamics in form of deterministic chaos has increased. Hence, the main purpose of this study was to detect if whether stock returns exhibit nonlinear and chaotic tendencies. By using...

It is worth mentioning that a great deal of financial liberalization, privatization and internationalization policies in emerging economies have significantly increased the corporate restructuring activities like mergers, acquisitions, share repurchases, and stock splits, among others. Indeed,...
