Over the periods 1998-2002 and 2009-2011, the S&P-500 Index went from persistence to anti-persistence mode, as measured by the Hurst index H. To uncover the reasons that characterize such a change, this paper uses a simple method that consists in treating quasi self-similar segments of the Index...

This paper shows that the observed output of any market, placed within the confine of a quadratic map, can characterize the state of that market. Such an approach explains the process of market share’s growth and its pitfalls, the consequences of broken symmetry of scaling, as well as the...

The purpose of this paper is to analyze the impact of the adoption of the Euro on trade within the Euro-zone, in particular on how it specifically affects the Iberian Peninsula, more specifically the country of Portugal. The literature on monetary unions has argued that there are benefits and...

The economic crisis in different parts of Latin America has given rise to consideration of dollarization as an option for many of these countries. Those countries that seek to replace their domestic currencies with the US dollar do so with the hope of achieving both growth and economic...

Since Leon Walras neoclassical economists hold an inalterable belief in a unique and stable equilibrium for the economic system which however remains to this day unobservable. Yet that belief is the corner stone of other theories such as the 'Effi-cient Market Hypothesis' as well as the...

The capital market is a reflexive dynamical input/output construct whose output (time series) is usually assessed by an index of roughness known as Hurst’s exponent (H). Oddly enough, H has no theoretical foundation, but recently it has been found experimentally to vary from persistence (H ...
