This paper studies the sequential sampling scheme as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value. Sequential sampling is analyzed and it is proved that when the sampling ratio is an integral number, the associated spectral...

Purpose: The scope of this paper is to see if the aggregate information and communications technology index (ICT) drives firm performance (profitability and efficiency) for BRICS countries from a des-aggregate panel data of the firm-yearly level (by country) during 2014-2022, from an aggregate...

To study the elasticities of import demand function, we build a heterogeneous panel with data of 40 counties and use panel unit root tests (Im, Pesaran and Shin, 1997) and panel cointegration tests (Pedroni, forthcoming). We test our model with two previously used activity variables: GDP and GDP...

This paper studies the long and short-run relationship between oil exports, non oil GDP and investment in five major oil exporting countries. Its goal is to verify the effect of natural resources exports on the economic performance. It considers the effect of cross sectional correlations and...

This paper reconsiders the A versus K debate, namely, which factor is the leading contributor to economic growth? productivity gains (A) or factor accumulation (K). The growth accounting analysis is conducted for ten Middle Eastern and North African (MENA) countries over the period 1960-1998....

This paper was presented in June 1974 at the Symposium ―On the Measurement of Factor Productivities‖ at the castle Reisensburg in Bavaria, and was published in the book of proceedings from this Symposium. It contains results of several years of research about the economies of six East...

This paper presents an essay on empirical testing procedure for economic convergence. Referring to the unit root test proposed by Moon and Perron (2004), we proposed a modified Evans (1996)testing procedure of the convergence hypothesis. The advantage of this modified procedure is that it makes...

We study the possibility of completing data bases of a sample of governance, diversification and value creation variables by providing a well adapted method to reconstruct the missing parts in order to obtain a complete sample to be applied for testing the ownership-structure / diversification...

Using time-series techniques and panels data, the paper analyses for the EU countries in the period 1970-2009 the existence and shape of the “BARS curve” (Barro, Armey, Rahn, and Scully), connecting the size of Government (measured by the share of public expenditure on GDP) to the rate of...
