Abstract: Detection of changes in the panel data setup is considered when $T$ (time dimension) is finite/moderate and $N$ (number of panels) tends to infinity. Some test procedures (no change versus there is a change) and estimators of the time of a change. A proper wild bootstrap procedure is proposed. The asymptotic behavior of the proposed test statistics and estimators is investigated. Theoretical results are accompanied by simulations and the application testing procedure in the framework a CAPM model.
