A new non-causality test based on the notion of distance between ARMA models is proposed in this paper. The advantage of this test is that it can be used in possible integrated and cointegrated systems, without pre-testing for unit roots and cointegration. The Monte Carlo experiments indicate...

The purpose of the study is to analyze the nature of inflation and unemployment rates -in Africa and its regions- allowing cross-sectional dependence among their countries. The paper contributes to the literature assessing the stochastic properties of unemployment and inflation using the...

In this paper we present a testing procedure for fractional orders of integration in the context of non-linear terms approximated by Fourier functions. The procedure is a natural extension of the linear method proposed in Robinson (1994) and similar to the one proposed in Cuestas and Gil-Alana...

This paper presents Rtadf (Right Tail Augmented Dickey-Fuller), an EViews Add-in that facilitates the performance of time series based tests that help detect and date-stamp asset price bubbles. Detection strategy is based on a right-tail variation of the standard Augmented Dickey-Fuller (ADF)...

This paper deals with testing a time series with a structural break in its mean for a unit root when the break date is known. A nonlinear (with respect to coefficients) test equation is used, providing asymptotically efficient estimates. Finite-sample and quasi-asymptotic empirical distributions...

The Cobb-Douglas production function has applications for firms, branches, industries, and for the macro-economies of nation-states as a whole. Throughout the course of his life, with the exception of his years as a senator, Paul H. Douglas consistently strived to gather all the supporting...

The paper provides new evidence on possible structural breaks in the relationship among business Confidence and industrial activity in Europe in the aftermath of the recession. Possible interpretation is that the crisis has determined a change in the pattern of response in surveys, firms now...

The article describes a dynamic general equilibrium for the Republic of Moldova, in the context of declining oil prices and COVID-19. We try to introduce an intergenerational model with the stochastic component, where we describe each self-employed agent, rather we try to adapt the model in a...
