Søren Johansen

Professor

Research Fields: Econometrics, mathematical statistics and probability theory, time series analysis, including  cointegration and its applications, fractional processes, outlier detection, robust statistics. 

Research groups: I am currently not a member of any research groups

Most essential academic contribution: My most influential work is related to cointegration of economic time series, which has had an impact on theory and practice in the application and analysis of macro economic time series. In collaboration with Katarina Juselius we have developed the theory and applications of these concepts and methods in the framework of the vector autoregressive model. The methods have widespread use in academia and applied macro economics.
