This paper shows through a Monte Carlo analysis the effect of neglecting seasonal deterministics on the seasonal KPSS test. We found that the test is most of the time heavily oversized and not convergent in this case. In addition, Bartlett-type non-parametric correction of error variances did...

This paper studies the dynamic effect of oil rents on industrial added value in a sample of countries with different levels of development. Using a SVAR model, we tested the effect of a real shock and a nominal shock on the variables of the model. The main obtained results are three. First, we...

This paper studies the dynamic effect of oil rents on the industrial added value in a sample of countries with different development levels. Using a structural vector autoregressive (SVAR) model, we tested the effect of a real shock and a nominal shock on the variables of the model. The main...

Although economic growth is considered to be one of the most discussed and studied topics by economists, some questions are hitherto unexplored. In this article we will try to address one of these issues by studying the effect of hegemonic countries’ growth shocks on the growth of peripheral...

The main objective of our study is to provide some answers to the following questions: What are the determinants of the expertise of the internet for the Tunisian teenager? What is the degree of influence of teenager, who is assumed an expert of the internet, in the process of family...

This article has for a core objective the handling of the established relation between oil price variation and certain macroeconomic variables, in this particular case GDP, RMM, CPI, Ex-factory price. The study in Tunisia is based on quarterly and monthly data from the period going from 2000 to...

The literature distinguishes finite sample studies of seasonal stationarity quite less intensely than it shows for seasonal unit root tests. Therefore, the use of both types of tests for better exploring time series dynamics is seldom noticed in the relative studies on such a topic. Recently,...

Few authors have studied, either asymptotically or in finite samples, the size and power of seasonal unit root tests when the data generating process [DGP] is a non-stationary alternative aside from the seasonal random walk. In this respect, Ghysels, lee and Noh (1994) conducted a simulation...
