Geopolitical Risk and Energy Markets: Past, Present, and Future

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Due to the most recent geopolitical events, such as the Russia–Ukraine conflict and the war between Israel and Hamas, geopolitical risk (GPR) and energy markets have been at the forefront of the academic debate. To identify the evolution of the literature inherent to GPR and energy markets, we conduct a meta‐literature review—that is ...

A note on Johansen's rank conditions and the Jordan form of a matrix

open access: yesJournal of Time Series Analysis, EarlyView.
This note presents insights on the Jordan structure of a matrix which are derived from an extension of the I(1) and I(2) conditions in Johansen (1996). It is first observed that these conditions not only characterize, as it is well known, the size (1 or 2) of the largest Jordan block in the Jordan form of the companion matrix but more generally the ...

Cointegrating Polynomial Regressions With Power Law Trends

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.
