For all the interest in experimentation, the majority of quantitative evidence used to form policy and practice takes the form of observational rather than experimental data. The volume of observational data now available is overwhelming, as the electronic capture of routine information becomes commonplace. Yet the use of such data gives rise to profound dangers of misinterpretation. This chapter explores the dangers associated with the analysis of non-experimental data, and describes the increasingly powerful tools used to handle such problems that are emerging from the discipline of econometrics.

Keywords:   econometrics, observational data, electronic capture, data misinterpretation, routine information, non-experimental data
