Financial crises have been a big problem lately, causing a lot of damage. This paper looks at how having too much money in the system can make these crises worse. They studied how money is created and found that when there's too much money floating around, it can mess up the balance between money and goods. If banks and authorities don't work together, things can get really unpredictable. By looking at the relationship between money and economic output, they found that when the money supply grows by more than 8%, it can lead to big financial crises. So, having too much money around can actually make things worse when a crisis hits.
