I think both similarities and differences can be illuminating. I am thinking that the ideological trends could be interesting to take a look at, Sweden in the 40ies had the Soc-dems settled into power and central planning was by and large viewed as efficient, while the 90ies had neoliberalism spreading through the world not least through the work of IMF (Yugoslavia in the 80ies being one of the first victims).

For example in Sweden in the 40ies there was (of course) a black market but it seems to mostly have involved the usual small-time criminals and one of the few cases of corrupt official I remember was very low in the hierarchy (stole coupons that was to be discarded, iirc) and was punished with jailtime.
