Evidence on long-term multigenerational dynamics is often inadequate as large datasets with multiple generations remain very uncommon. We posit that genealogical records can offer a valuable alternative. Rather than exploring the intergenerational transmission of socioeconomic status, we rely on...

The literature on parent-child correlations in socioeconomic status provides little evidence on long-term multigenerational dynamics. This is because most studies of intergenerational status persistence are based on two (at most three) successive generations. Our analysis adds to the...

The paper provides a first survey of the literature on external validity. The starting point for this are debates regarding the use of randomised evaluations to inform policy. Besides synthesising contributions to the programme evaluation literature we consider definitions of external validity...

Reichenbach's 'principle of the common cause' is a foundational assumption of some important recent contributions to quantitative social science methodology but no similar principle appears in econometrics. Reiss (2005) has argued that the principle is necessary for instrumental variables...
