Some Methodological Issues in Cohort Analysis of Archival Data

The Impact of Cohort Membership on Disposable Incomes in West Germany, France, and the United States

“…While many papers proposed empirical estimations of the three effects (Mason, et al 1973;Fienberg / Mason 1979), an "identification problem" besets all APC models (Glenn 1976;Mason / Wolfinger 2001). This arises from the equation: a=p-c. That is, each variable is a combination of the other two.…”

Life-course and cohort trajectories of mental health in the UK, 1991–2008 – A multilevel age–period–cohort analysis

“…Whilst this has been part of the literature for decades (Glenn, 1977;Mason et al, 1973;Ryder, 1965), serious misunderstandings remain across the social sciences (Bell & Jones, 2014b). This section clarifies these misunderstandings before considering their relevance to understanding changing mental health.…”

“…Regardless, many have attempted to solve the identification problem statistically (Mason et al, 1973;Robertson & Boyle, 1986). Some group one of APC to break the exact collinearity producing results that arbitrarily depend on the chosen grouping (Glenn, 1976;Osmond & Gardner, 1989).…”

Origins of Social Capital: Socialization and Institutionalization Approaches Compared

“…Such effects are commonly labeled cohort (or generational) effects, i.e. the effect of a generation entering a population with distinctive values on a variable which thereafter persists (Claggett, 1981;Mason et al, 1973). The same properties are carried on throughout the life cycle and over time change the overall distribution on the variable in the population as a whole.…”
