Two main purposes of econometrics are to give empirical content to economic theory by formulating economic models in testable form and to estimate those models and test them as to acceptance or rejection. Topics discussed in this compilation include an assessment of the econometric methods for program evaluation and a proposal to extend the difference-in-differences estimator to dynamic treatment; empirical estimations of FDI spillovers; econometric modelling of time to event data; regression and data envelopment analysis methods to assess practice efficiency and implication of instability on econometric and financial time series modelling.
