This article employs six techniques and tools such as chart analysis, chart recurrence, space temporary entropy, Hurst coefficient, Lyapunov exponent and dimension correlation on the copper, gold, oil, silver, zinc, aluminum, nickel, and lead return series to corroborate the existence of a...

There is an increasing awareness of the potential of nonlinear modeling in regional science, which can partly be explained by the recognition of the limitations of conventional equilibrium models in complex situationsand partly by the easy availability and accessibility of sophisticated...

This article presents an exhaustive analysis of the normal distribution assumption in terms of emerging capital markets. The accuracy of such assumptions is fundamentally contested by the results of empirical analysis. In addition, this paper is also a conceptual debate between classical theory...

As the economy enters a phase transition into an aperiodic state, the tech industry finds itself at the brink of chaos. Inflated evaluations in private markets before IPOs and increasing Shannon entropy of post-IPO share prices reveal a market teetering on the edge. But is it a phase transition,...

This paper investigates chaos in a Nigerian mutual fund, Asset and Resource Management Company Limited (ARM) for a period of eleven years. The existence of chaotic signals in the data was identified by the reconstruction of the phase space of the daily closing price of the fund and the delay...

This study examines the market efciency in the prices and volumes of transactions of 41 cryptocurrencies. Specifcally, the correlation dimension (CD), Lyapunov Exponent (LE), and approximate entropy (AE) were estimated before and during the COVID-19 pandemic. Then, we applied Student's t-test...

In this paper the author analyzes the behavior of exchange rates expectations for four currencies, by considering a re-calculation and an extension of Resende and Zeidan (Expectations and chaotic dynamics: Empirical evidence on exchange rates, Economics Letters, 2008). Considering Lyapunov...
