Human resources are an essential element in territorial development. When the same are characterized by a high level of training are enhancers of a series of effects which are essential in the relationship between territorial and social cohesion. In this regard, the existence of higher education...

In this reply, we provide detailed answers to the remarks made by Tsionas on the use of stochastic frontier-based measures of market power in a part of our empirical study, which examines the fragmentation and convergence dynamics of market power, concentration and credit risk in the euro area...

This paper investigates greenhouse gas emissions convergence among twenty Latin American countries, for the period 1970 to 2015. To that end, we use the Phillips-Sul methodology to examine whether these countries have followed an absolute convergence process or, whether there has been a club...

The geometric Brownian motion is the solution of a linear stochastic differential equation in the Itô-sense. If one adds to the drift term a possible nonlinear time delayed term and starts with a nonnegative initial process then the process generated in this way, may hit zero and may oscillate...

This paper studies the oscillatory properties of solutions of linear scalar stochastic delay differential equations with multiplicative noise. It is shown that such noise will induce an oscillation in the solution whenever there is negative feedback from the delay term. The zeros of the process...

Assume L is a non-deterministic real valued Lévy process and f is a smooth function on [0,t]

We consider the problem of strong approximations of the solution of stochastic functional differential equations of Itô form with a distributed delay term in the drift and diffusion coefficient. We provide necessary background material, and give convergence proofs for the Euler-Maruyama and the...
