The Effect of Bank Failures on Small Business Loans and Income Inequality
Salvador Contreras, Amit Ghosh, Iftekhar Hasan
Journal of Banking and Finance,
Vol. 146 (January),
2023
Abstract
Using variation in the timing and location of branches of failed banks we analyze its effect on income inequality. Employing a difference-in-differences specification we find that bank failures increased the GINI by 0.3 units (or 0.7%). We show that the rise in inequality is due to a decrease in the incomes of the poor that outpaces declines of the rest. We further show that individuals with lower levels of education exhibit a relatively greater decline in real wages and weekly hours worked. Exploring channels of transmission, we find income inequality is explained by a general decline in small business loans. This in turn reduces net new small business formation and their job creation capacity, a sector that hires a substantial share of low-income earners.

Bank Failures, Local Business Dynamics, and Government Policy
Salvador Contreras, Manthos D. Delis, Amit Ghosh, Iftekhar Hasan
Small Business Economics,
Vol. 58 (4),
2022
Abstract
Using MSA-level data over 1994–2014, we study the effect of bank failures on local business dynamics, in the form of net business formation and net job creation. We find that at least one bank failure in the metropolitan statistical area (MSA) with the mean population prevents approximately 475 net businesses from forming in that area, compared with MSAs that experience no bank failures, ceteris paribus. The equivalent effect on net job creation is 16,433 net job losses. Our results are even stronger for small businesses, which are usually more dependent on bank-firm relationships. These effects point to significant welfare losses stemming from bank failures, highlighting an important role for government intervention. We show that the Troubled Asset Relief Program (TARP) is effective in reducing the negative effects of bank failures on local business dynamics. This positive effect of TARP is quite uniform across small and large firms.

Income Inequality and Minority Labor Market Dynamics: Medium Term Effects from the Great Recession
Salvador Contreras, Amit Ghosh, Iftekhar Hasan
Economics Letters,
Vol. 199 (February),
2021
Abstract
Using a difference-in-differences framework we evaluate the effect that exposure to a bank failure in the Great Recession period had on income inequality. We find that it led to a 1% higher Gini, relative rise of 38 cents for high earners, and 7% decline for lowest earners in treated MSAs. Moreover, we show that blacks saw a decline of 10.2%, Hispanics 9.8%, and whites 5.1% in income. Low income blacks and Hispanics drove much of the effect on inequality.

Four Essays on Financial Stability and Competition with Heterogeneous Banks
Carola Müller
PhD Thesis, OvG-Universität Magdeburg,
2018
Abstract
Finding the proper balance between state and market is challenging. Especially in banking (Stiglitz, 1993). Banks in their function as financial intermediaries are risky and inherently prone to failure (Diamond and Dybvig, 1983; Diamond, 1984). But they provide services of vital importance to the economy in the form of payment services, credit supply for investments, inter-temporal liquidity transformation, or management of savings accounts. Consequently, the stability of the banking and financial sector is of public interest. In the least, the financial crisis was an unpleasant reminder to the industrialized world about the severe repercussions of unstable banking systems.

Ailing banks increase leverage of ailing firms
Euro area countries such as Greece and Spain continue to struggle not only with their banks, but also with highly indebted domestic firms. Michael Koetter from the Halle Institute for Economic Research (IWH) and co-authors show the failure to resolve banks’ financial difficulties also prevents debt reduction of over-leveraged firms – and sometimes even contributes to increasing leverage of the weakest firms.
