On he con a y, some o he esea ch cap u es coun e -cyclical pa e ns o mo ali y

In his ega d, i is discussed ha he p esence o some so o insu ance schemes

Following hese con adic o y indings, some li e a u e c i icizes he use o unem-

Fu he mo e, some o he s ha e a o ed s udying age-speci ic mo ali y ins ead o

The e is mo e empi ical e idence o p o-cyclical a ia ions in he heal h s a us o he

obse e ha he p o-cyclical pa e n ound o he US does no hold o aged popula ion

Canadian go e nmen . Ne e heless, he wo king-age popula ion in Canada s ill shows

In addi ion, i is discussed ha he ela ionship be ween mac oeconomic condi ions
and mo ali y may al e o e ime. Consequen ly, some ecen s udies ha e examined
his link wi h mo e ecen da a. Ruhm (2015) ex ends his analysis o 2009 o he US
and concludes ha o e he las h ee decades, o al mo ali y changed om being

e al. (2013) do no cap u e any e idence o he e ec s o he ecen inancial c isis on
heal h beha io in he US. Also, based on agg ega e da a o he US o e 1961–2010 and
using a ime- a ying pa ame e (TVP) model, Lam and Pié a d (2017) conclude ha
in ecen yea s, he des uc i e in luence o inc eased wo king hou s on indi iduals’

Finally, some p io esea ch looks a mo ali y beha io among di e en socio-
economic g oups. Edwa ds (2008) inds ha he p o-cyclical mo ali y in he US
is limi ed o wo king-age males wi h high school o highe educa ional a ainmen .
In addi ion, Xu (2013) ind e idence o wo sening he men al heal h o educa ed

These s udies, al hough wi h opposing esul s, add ess di e en aspec s o indi idu-
