Organizational citizenship behavior has always been tested in the knowledge-intensive sectors of societies. Organizational citizenship behavior is a voluntary and discretionary behavior that is supposed to build up the cultural aspect of the organization; it is not part of the personnel's contractual tasks and can contribute to the successful implementation of the organization's objectives. The...

This paper considers cointegration tests for dynamic systems where the number of variables is large relative to the sample size. Typical examples include tests for unit roots in panels where the units are linked by complicated dynamic relationships. It is well known that conventional cointegration tests based on a parametric (vector autoregressive) representation of the system break down if the...

Weighted versions of the likelihood ratio, Wald, score and disparity tests are proposed for parametric inference. If the parametric model is correct, the weighted likelihood tests are asymptotically equivalent to the corresponding likelihood based tests, while the disparity test has asymptotically the same distribution as that of ∑p i=1 λiZ 2 i , where Zi are standard normal random variables an...
