Professor Steve Cook has research interests in a number of areas of theoretical and applied econometrics and is the author of over 100 fully refereed articles in a range of econometrics, economics, mathematics and statistics journals. One feature of Professor Cook’s research is the development and analysis of alternative modified unit root and cointegration tests. This research has necessitated the extensive use of numerical simulation techniques and the empirical analysis of a number of national and international economic and financial time series. More recent research has considered the impact of conditional heteroskedasticity upon the finite-sample behaviour and distributions of test statistics commonly employed in econometrics and time series analysis. The examination of non-linear and asymmetric dynamic adjustment in time series processes is a further continuing theme of Professor Cook’s research activity.
