The `local rank factorization' (lrf) of a regular matrix polynomial at an eigenvalue consists of a sequence of matrix rank factorizations of a certain function of its coecients; the lrf delivers the local Smith form and extended canonical systems of root functions that correspond to the...

We develop a sieve bootstrap range test for poolability of cointegrating regressions in dependent panels and evaluate by simulation its performances. Although slightly undersized the test has good power even when only a single unit of the panel is heterogenous.

We estimate the long-run demand for broad money at the Gulf Cooperation Council area level (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE)) and at single country level over the 1980-2009 period. Applying time series and panel econometric tests, we first document...
