We introduce a new regression diagnostic, tailored to time-series and panel-data regressions, which characterizes the sensitivity of the OLS estimate to distinct time-series variation at different frequencies. The diagnostic is built on the novel result that the eigenvectors of a random walk...

A plethora of research activity on the relationship between a country’s export and economic growth has produced ambiguous and mixed results. We reinvestigate this relationship using the methodology of wavelets based correlation and cross correlation. Our results show that the relationship...
