Labor unions and bank risk culture: evidence from the financial crisis

In this paper, we examine the effect of labor unions on bank performance during the recent financial crisis. Empirical evidence from the 314 largest global banks indicates that the stock returns and profitability of unionized banks are higher, and the default probabilities are lower than non-unionized banks. Moreover, unionized banks have lower tail risk in their stock returns, more tangible equity, more liquid assets, and better quality lending before the crisis than non-unionized banks. These finding show that unionized banks operate more conservatively and engage in less risk-taking. Our results imply that union preferences can shape the risk culture of banks.
