This is absolutely no cause for concern whatsoever. In the fixed effects model, as previously noted, this all gets washed out anyway because the 'treatment' effect is completely confounded with the fixed effect and gets dropped from the model only the effects of things that vary within subjects are estimated. So, in general, one expects the coefficient of the treatment variable to be close to zero and one prefers it to be not statistically significant when doing this kind of model.

In an observational study, of course, one has less confidence that the expected difference in the two groups prior to exposure would be zero-but even there, if the two groups really differed greatly at baseline that would be cause to worry about the applicability of a DinD model as well. 7.8 The Linear Panel Data Model, Revisited 169 7.8.1 Assumptions for Pooled OLS 170 7.8.2 Dynamic Completeness 173 7.8.3 A Note on Time Series Persistence 175 7.8.4 Robust Asymptotic Variance Matrix 175 7.8. In fact, if your treatment and control groups were randomly assigned, you would expect it to be zero, and you would have some concerns about the adequacy of your randomization if it were not close to zero. In this context, the coefficient of treatment is not a 'treatment effect,' it is instead the expected difference of the outcome variable in the two arms (treatment arm - control arm) in the base year only. But the naming of those effects is completely misleading. You would get separate estimates for treatment, year, and treatment#year.

Stata would not complain about collinearity in that case.

Suppose you had used a random effects model instead of fixed-effects. Cambridge University Press 2002, 384 pages ISBN: 0521522714, 0521818559 Cheng Hsiao has made many significant and important contributions to panel data econometrics, both methodological and. Excel Tables have wonderful properties that allow you to work more efficiently. Here, we offer some tips for work: Create auto expandable ranges with Excel tables: One of the most underused features of MS Excel is Excel Tables. Data Analysis is simpler and faster with Excel analytics.

And it's certainly not true in the DinD context. How to Analyze Data in Excel: Data Analysis. Even outside this particular context that's not true. An unbalanced panel is one where individuals are observed a different number of times, e. Here we require that all individuals are present in all periods. but if one of the terms of the interaction is lost (due to collinearity) or is statistically non-significant does not it make the interaction non-significant as well? Policy Analysis with Two-Period Panel Data Two period panel data is often used for program evaluation studies in which there is likely to be endogeneity Example: Evaluation of Michigan Job Training Program Data for two years. Data structures: Panel data A special case of a balanced panel is a xed panel.
