In this paper, we focus on the Granger causality test in the presence of regime shift. We apply a vector autoregressive (4) model on Swedish series of industrial output and consumer price index for the period 1980:1‐1998:6. To test for causality, three different test methods namely the single equation Likelihood Ratio test, the systemwise Rao's F‐ test and the Bootstrap test, have been used in this study. We show that when the assumption of parameter constancy is violated, due to the occurrence of the structural changes, Granger causality tests can provide misleading inference about the underlining relationship of causality.

There is now a large amount of literature on immigrants' relative earnings and immigrants' earnings assimilation in different countries. This paper aims to contribute to international research, since the paper investigates the earnings gap between different groups of immigrants and natives at different parts of the earnings distribution in Sweden.

Quantile regressions are estimated on a large dataset in order to study to what extent there are differences in the earnings gap between different groups of immigrants and natives at the top and the bottom of the earnings distribution in Sweden.

The study shows, that immigrants are doing relatively better at the top than at the bottom of the earnings distribution. This is the case for males as well as for females. Furthermore, the study also shows that in times of recession, the earnings gap between immigrants from European countries and natives remains stable, while the earnings gap between non‐European immigrants and natives at the bottom of the earnings distribution increases substantially.

This paper is useful to those wishing to examine the extent of differences in earnings between immigrants and natives and differences in earnings between different immigrant groups.

The purpose of this study is to investigate the value of cloud computing adoption (CCA) as a proxy for information technology (IT) flexibility (ITF) and IT effectiveness (ITE) among Small- and medium-sized enterprises (SMEs) in Jordan.

A research framework with five hypotheses has been developed based on the results of previous studies. Partial least squares-structural equation modeling has been used for data analysis.

The results revealed that elements of ITF in two domains, IT technical resource (connectivity, modularityand compatibility) and IT human resource (IT personnel skills) specific to CCA, were significantly correlated with ITE.

The findings have crucial implications: they contribute to the research community, administrators and cloud computing providers (CSPs) concerning the framework-improved procedure for CCA. The proposed model can enhance the awareness of service providers about why some SMEs accept cloud computing services, whereas actually the same ones having the same type of business do not. In addition, the above providers should enhance their interaction with the SMEs that contributed to the cloud computing knowledge to make a well-organized setting for the CCA, specifically, SMEs need that adopt an on-premise private cloud architecture. Moreover, necessary to determine the challenges in deploying solutions from the perspective of CSPs. The sample has been limited to Jordan respondents.

The research studies about the usage of cloud computing have shown its effects on SMEs today. Also, the different impacts of cloud computing on other sectors are at the center of attention. SMEs could get significant advantages by carefully considering and managing CCA from the ITF and ITE perspective.

To the best of the author’s knowledge, this is the first study to develop a framework for CCA based on the standpoint of ITF in two domains, IT technical resources (connectivity, modularity and compatibility) and IT human resources (IT personnel skills) and effectiveness.
