Recently, considerable emphasis has been placed on the problems arising out of cross-sectional dependence in panel unit root tests. This paper adopts the factor based cross-sectional dependence paradigm of Bai and Ng (2004) but suggests alternative factor extraction methods. Some theoretical results for these methods are provided. Further, a detailed Monte Carlo study of these methods for multi...

background health expenditures are divided in two parts of public and private health expenditures. public health expenditures contain social security spending, taxing to private and public sectors, and foreign resources like loans and subventions. on the other hand, private health expenditures contain out of pocket expenditures and private insurances. each of these has different effects on the ...

Using panel data, this paper tests whether public and private capital have a positive and significant effect on aggregate output and labor productivity for Mexico during the 1960-2001 period. The richer information set made possible by the sectorial data enables this study to utilize the methodologically sound “group-mean” Fully Modified Ordinary Least Squares (FMOLS) procedure developed by Ped...

Abstract In this study, we applied recently developed panel unit root and cointegration techniques to examine the long-run real income per capita and price elasticities for demand of electricity in selected Middle East and North African (MENA) countries using an annual data series from 1990 to 2011.Our main finding from the panel analysis is that the demand for electricity is highly price ela...

T his paper proposes a new unit root test against the alternative of symmetric or asymmetric exponential smooth transition autoregressive (AESTAR) nonlinearity that accounts for multiple smooth breaks. We provide small sample properties which indicate the test statistics have good empirical size and power. Also, we compared small sample properties of the test statistics with Christop...

Research & development expenditures, which are innovative and creative work, evaluated as an substantial factor in productivity, competitiveness, sustainable growth performance developed countries. This study, is targeted to empirically analyze the impact of research expenditures on economic unemployment 25 selected countries from years 1996-2020. Panel data analysis was carried out with me...

BACKGROUND Over the last decade there has been an increase in healthcare expenditures while at the same time the inequity in distribution of resources has grown. These two issues have urged the researchers to review the determinants of healthcare expenditures. In this study, we surveyed the determinants of health expenditures in Economic Cooperation Organization (ECO) countries. METHODS We us...
