Panel data - i.e. the observation of multiple variables over multiple time intervals for the same units of analysis - often suffer from various violations of the Gauss-Markov assumptions. For example, in many settings it can hardly be assumed that repeated measurements within units are independent of each other. In contrast to seminal pooled time-series models, multilevel approaches can directly model such dependencies by allowing for varying intercepts and slopes. This enables us to disentangle temporal from cross-sectional variation and to study their cross-level interactions.

Angesichts eines steigenden Anteils älterer Menschen an der Bevölkerung westlicher Industrienationen wird in den letzten Jahren unter dem Stichwort des „Produktiven Alter(n)s“ zunehmend die Möglichkeit produktiver Tätigkeiten dieser Menschen diskutiert. Damit ist einerseits die längere Beteiligung am Erwerbsleben gemeint, andererseits verschiedene andere Partizipationsformen, wie ehrenamtliches Engagement, Pflegetätigkeiten, die Betreuung von Enkelkindern und sonstige informelle Unterstützungsleistungen.
