The types of collateral that lenders demand as a security when awarding loans depend to a large extent on whether the lenders have positive or negative expectations for the development of the economy. For lenders with a positive outlook who expect favorable economic developments, the collaterals they demand from their borrowers are smaller in volume. This makes it easier for borrowers to obtain bank loans. If the sentiment is negative, however, lenders fear that the borrowers may default on their loans and therefore step up their collateral requirements.

Using a macroeconomic mathematical model, the researchers were able to show that swings between pessimistic and optimistic sentiment lead to stronger income fluctuations over the business cycle. At the same time, the cycles become more regular. The study shows that the financial markets are influenced by behavioral aspects. The findings provide the basis for more applied research on how to design regulation schemes for financial markets. The goal of this research is to make economies more stable and resilient.
