This paper considers a Kaleckian type model of business cycle based on a nonlinear delay differential equation, whose associated characteristic equation is a transcendental equation with delay dependent coefficients. Using the conventional analysis i

Cyberspace consists in a complex mix of data, devices, and people. The virtual environment is based on different types of network layers, each of which has nodes that are locatable in space-time. Taking advantage of the growing volume of location-bas

We introduce a novel score-driven model with two sources of shock, allowing for both time-varying volatility and jumps. A theoretical investigation is performed which yields sufficient conditions to ensure stationarity and ergodicity. We extend the m

This article originally seeks to explore the impact of R&D investments and societal culture on green technology management, by applying Hofstede’s cross-cultural perspective. At large, we investigate if green innovation is positively associated to

In the popular BEKK and DCC multivariate GARCH models, the high number of parameters and the requirement of the positive definiteness of the covariance and correlation matrices pose some difficulties during the estimation process. To avoid these issu

We show that the performances of the finite difference method for double barrier option pricing can be strongly enhanced by applying both a repeated Richardson extrapolation technique and a mesh optimization procedure. In particular, first we constru

We introduce a new infinitely smooth generalized Gaussian radial basis function (GGRBF) involving two shape parameters: ψ ( r ; ϵ ; ϵ 0 ) = φ ( r ; ϵ ) exp ( φ ( r ; ϵ 0 ) − 1 ) , where φ(r; ϵ) is the Gaussian basis associated with the sha

The increasing presence of humanoid robot adoption has generated a change in explorative and exploitative routines. If the explorative routines provoke creativity and critical thinking which are delivered by humans, exploitative routines induce repet
