In 1771, the first Swedish academic thesis on bankruptcy and insolvency was defended by Carl Bergström at Uppsala University. In this and other contemporary Swedish publications on the topic, shortcomings in the debtor’s character including gambling, dishonesty, fraudulent behaviour and a disposition for speculation were mentioned as major causes for bankruptcies. The idea that a debtor also was a swindler, and should be severely punished, was spread by Italian merchants to, above all, France, Spain, England and Germany. The moralising causal explanation for bankruptcy can be questioned from a social science research perspective. Based on modern literature, we can see many reasons for why a trader, shopkeeper or an artisan had to file for bankruptcy. An economic shock is an event that occurs outside of an economy and produces significant change within an economy.
