Abstract
In this article, we combine the Johansen procedure for cointegration testing with tests of weak exogeneity and invariance in order to ascertain whether a system of equity markets is characterized by superexogeneity. Superexogeneity is rejected for the system comprised of stock indices of the US, UK, Germany and Japan. This finding implies that agents participating in these financial markets are forward looking, all markets are endogenous in our system and the assumption of stability of the asset demand function is questionable.

Lori Leachman
Professor Leachman is interested in studying the subjects of international trade, exchange rates, fiscal policy, and international macroeconomics. In conducting her research, she often incorporates intertemporal models, multicointegration and sustainability. Her current research project explores the political economy of intertemporal budgeting. She recently collaborated with G Rosas, A Bester, and P. Lange to complete a study on, “The Political Economy of Budget Deficits,” and worked with the same team on the project entitled, “Multicointegration and Sustainability of Fiscal Practices.” She has also teamed up with Bill Francis to publish the works, “Twin Deficits: Apparition or Reality?” and “Multicointegration Analysis and the Sustainability of Foreign Debt.” One of her earlier works, executed with Michael Thorpe, was a study on, “External Balance in the Small Open Economy of Australia.” She has also published on such subjects as capital market integration, optimum corporate capital structure, and Ricardian equivalence.
More recently, Dr. Leachman has turned her attention to creative writing. Specifically, she has written a memoir about growing up in the South, football, and her father's death from CTE. The book titled, "The King of Halloween and Miss Firecracker Queen," will be released in May of 2018. As a result of these efforts, Dr. Leachman is currently working on framing the legal and ethical issues surrounding football and the issue of informed consent.
