Chancellor Seghir Publishes Research in High-Impact Economics Journal

Dr. Karim Seghir, Chancellor of Ajman University, has co-authored a research paper with Dr. Mario Rui Pascoa, Professor of Economics at the University of Surrey, about “Recourse Loans and Ponzi Schemes.” The article was published on July 26, 2019 in Economic Theory – an international journal with an impact factor of 0.961, as well as an A* quality rating from the Australian Business Deans Council (ABDC) and a Q1 from SCOPUS.

“I am pleased to contribute to the growing intellectual output of Ajman University, where the pursuit and publication of high-quality and high-impact research is strongly supported,” says Chancellor Seghir, who continues to prioritize time for research in his area of expertise.

In his ongoing academic career as a scholar of mathematical economics and finance, Dr. Seghir has published research papers in Games and Economic Behavior(A* in ABDC and Q1 in Scopus), Journal of Mathematical Economics (A* in ABDC and Q1 in Scopus), as well as previous issues of Economic Theory.

The new paper by Dr. Karim and Dr. Pascoa examines equilibrium existence in infinite-horizon models where sales of promises are secured by collateral and defaulters suffer utility penalties. The paper shows that Ponzi schemes are ruled out and equilibrium does exist in some interesting cases: (1) if utility penalties are low enough and the collateral does not yield utility (for example, when it is a productive asset or a security); or (2) for a nominal promise backed by real collateral (such as mortgages, whose payments are not tied to a commodity price index).

Since 2017, when the internal research budget as increased by 300%, the number of papers published by AU faculty in SCOPUS-indexed outlets has doubled.  Nearly half of those papers were published with co-authors outside UAE.
