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...

This paper investigates dynamic conditional correlations between stock and REIT markets in both Turkey and the U.S. We use an Asymmetric DCC - GJR - GARCH model to estimate the dynamic conditional correlation at daily, weekly, and monthly frequencies. Our contribution is threefold. First, we...

The objective of the paper is to obtain results on the behavior of a specific plane discontinuous dynamical system in the neighbourhood of the singular point. A new technique of investigation is presented. Conditions for existence of the foci and centres are proposed. The focus-centre problem...

Plouffe studied the recurrences , and (defined below). Plouffe's constant [1] arises from the recurrence . We present a closely related constant, ç, arising from the recurrence and like Plouffe's constant it has a feasible algorithm (more efficient) for its th digit and can be constructed by a...

In this paper, we focus on the stochastic (chaotic) attributes of the US dollar-based exchange rates for Brazil, Russia, India, China and South Africa (BRICS) using a long-run monthly dataset covering 1812M01-2017M12, 1814M01-2017M12, 1822M07-2017M12, 1948M08-2017M12, and 1844M01-2017M12,...

Literature on punctuated equilibrium theory has aimed to explain the causes of policy punctuations. What remains unknown are the consequences of those punctuations (and other size changes) for organizations. Specifically, this study analyzes how budgetary changes affect organizational...
