BUT ! How to distinguish durable scarring effects and fads ???
Hysteresis = stability versus Resilience = resorption of scars

Cohort coefficents of the APC model of bachelor (and+) degree owners
h<0 => “resilience”: decreasing cohort fluctuations over life course.
h=0 => “hysteresis”: stability of cohort effect over life course
h>0 => “cohort Matthew effect”: increasing cohort fluctuations
Examples there :
3. Substance: diffusion of diploma and occupational prestige/class in France and the US
The file is a 1975-2008 United States Current population survey. There is no intersection with the previous file. The size of the extract containing population between age 20 and 64 is n= 1.285.367. It is an extract from IPUMS-CPS Minnesota site.
The French file is similar: a « Enquête Emploi » (1975-2008) cumulative file (size of the extract containing people between age 20 and 64 is n=942 550).
Source : Enquêtes emploi 1970-2005 N= 774.424
4. Results: strong effects in France with no resilience weak effect in the US and resilience

4. Results: strong effects in France with some resilience weak effect in the US and hysteresis
