The study's abstract:
"By running an experiment among Germans collecting their passports or ID cards in the citizen centers of Berlin, we find that individuals with an East German family background cheat significantly more on an abstract task than those with a West German family background. The longer individuals were exposed to socialism, the more likely they were to cheat on our task. While it was recently argued that markets decay morals (Falk and Szech, 2013), we provide evidence that other political and economic regimes such as socialism might have an even more detrimental effect on individuals’ behavior.
1) 'socialism' is a loaded word here. There were other differences between east and west Germany than simply the economic system. Any reading of history that doesn't acknowledge that is disingenuous.
2) "family background" does not equate to exposure to an economic system. Are you telling me that if I have children after having lived under a specific economic regime I'll have somehow infected them with specific values derived from that system? That's crazy!
3) This study was done by a group of business professors. We can't expect business proferssors to do anything but advocate for free markets, it's something of their jobs to be advocates for it.
In all this study looks like a complete waste that doesn't contribute anything to our understanding of values and economics. An area that I'm actually interested in, and like to read papers on occasionally.
