Income Inequality and Minority Labor Market Dynamics: Medium Term Effects from the Great Recession

Salvador Contreras Amit Ghosh Iftekhar Hasan

in: 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.

Local Banks as Difficult-to-replace SME Lenders: Evidence from Bank Corrective Programs

Iftekhar Hasan Krzysztof Jackowicz Robert Jagiełło Oskar Kowalewski Łukasz Kozłowski

in: Journal of Banking and Finance, Vol. 123 (February), 2021

Abstract

In this study, we assess capabilities of different types of banks to cater to the financial needs of small and medium-sized enterprises (SMEs). Using a comprehensive dataset from an emerging economy, including the information on local banks’ corrective programs, we find that local banks remain difficult-to-replace lenders for SMEs. We show that presence of healthy local banks in an SME's vicinity immunizes the SME against the deterioration of access to bank financing linked to other local banks’ corrective programs. In contrast, large banks are unable to replace the lost lending from local competitors under corrective programs.

Is Social Capital Associated with Corporate Innovation? Evidence from Publicly Listed Firms in the U.S.

Iftekhar Hasan Chun-Keung (Stan) Hoi Qiang Wu Hao Zhang

in: Journal of Corporate Finance, Vol. 62 (June), 2020

Abstract

We find that social capital in U.S. counties, as captured by strength of social norms and density of social networks, is positively associated with innovation of firms headquartered in the county, as captured by patents and citations. This relation is robust in fixed-effect regressions, instrumental variable regressions with a Bartik instrument, propensity score matching regressions, and a difference-in-differences design that isolates the effects of over time variations in social capital due to corporate headquarter relocations. Strength of social norms plays a more dominant role than density of social networks in producing these empirical regularities. Cross-sectional evidence indicates the prominence of the contracting channel through which social capital relates to innovation. Additionally, we find that social capital is also positively associated with trademarks and effectiveness of corporate R&D expenditures.

Profit Shifting and Tax‐rate Uncertainty

Manthos D. Delis Iftekhar Hasan Panagiotis I. Karavitis

in: Journal of Business Finance and Accounting, Vol. 47 (5-6), 2020

Abstract

Using firm‐level data for 1,084 parent firms in 24 countries and for 9,497 subsidiaries in 54 countries, we show that tax‐motivated profit shifting is larger among subsidiaries in countries that have stable corporate tax rates over time. Our findings further suggest that firms move away from transfer pricing and toward intragroup debt shifting that has lower adjustment costs. Our results are robust to several identification methods and respecifications, and they highlight the important role of tax‐rate uncertainty in the profit‐shifting decision while pointing to an adjustment away from more costly transfer pricing and toward debt shifting.

Enforcement of Banking Regulation and the Cost of Borrowing

Yota D. Deli Manthos D. Delis Iftekhar Hasan Liuling Liu

in: Journal of Banking and Finance, Vol. 101 (April), 2019

Abstract

We show that borrowing firms benefit substantially from important enforcement actions issued on U.S. banks for safety and soundness reasons. Using hand-collected data on such actions from the main three U.S. regulators and syndicated loan deals over the years 1997–2014, we find that enforcement actions decrease the total cost of borrowing by approximately 22 basis points (or $4.6 million interest for the average loan). We attribute our finding to a competition-reputation effect that works over and above the lower risk of punished banks post-enforcement and survives in a number of sensitivity tests. We also find that this effect persists for approximately four years post-enforcement.

Employment Responses to Increased Biodiversity Transition Risk

Duc Duy Nguyen Huyen Nguyen Trang Nguyen Vathunyoo Sila

in: IWH Discussion Papers, Nr. 20, 2025

Abstract

This paper examines how firms adjust the number and types of workers they hire in response to increased biodiversity transition risk. Using the adoption of the Key Biodiversity Areas Standard of 2016 as a source of variation that increases the risk of future land-use restrictions, we find that firms reduce job postings in affected areas and reallocate labor to less exposed regions. This effect is concentrated among firms that make negative impacts on biodiversity. Cuts are stronger among production roles, while hiring in green and adaptive occupations increases. The effect is not driven by changes in capital investment or workers’ labor supply decisions. Our findings contribute to the ongoing debate on the costs and benefits of biodiversity conservation policies and their implications for labor market outcomes.

What’s the Melting Pot Worth? Multiculturalism and House Prices

Rachel Cho Hisham Farag Christoph Görtz Danny McGowan Huyen Nguyen Max Schröder

in: IWH Discussion Papers, Nr. 11, 2025

Abstract

Is there a multicultural neighborhood price premium? We exploit plausibly exogenous variation in British colonization patterns in Northern Ireland during the early 1600s which created neighborhoods of varying religious composition that persists until today. These religious groups are culturally distinct, but are observationally equivalent ethnically and socioeconomically. A standard deviation increase neighborhood-level multiculturalism raises house prices by 9.6%. Multiculturalism raises property prices by increasing asset liquidity and housing demand as a wider spectrum of society demand houses in these areas. The findings and mechanism contrast sharply with prior evidence showing negative relationships due to homophily, social networks, and identification challenges.

Supply Chain Disruptions and Firm Outcomes

Michael Koetter Huyen Nguyen Sochima Uzonwanne

in: IWH Discussion Papers, Nr. 3, 2025

Abstract

This paper examines how firms’ exposure to supply chain disruptions (SCD) affects firm outcomes in the European Union (EU). Exploiting heterogeneous responses to workplace closures imposed by sourcing countries during the pandemic as a shock to SCD, we provide empirical evidence that firms in industries relying more heavily on foreign inputs experience a significant decline in sales compared to other firms. We document that external finance, particularly bank financing, plays a critical role in mitigating the effects of SCD. Furthermore, we highlight the unique importance of bank loans for small and solvent firms. Our findings also indicate that highly diversified firms and those sourcing inputs from less distant partners are less vulnerable to SCD.

Environmental Incidents and Sustainability Pricing

Huyen Nguyen Sochima Uzonwanne

in: IWH Discussion Papers, Nr. 17, 2024

Abstract

We investigate whether lenders employ sustainability pricing provisions to manage borrowers’ environmental risk. Using unexpected negative environmental incidents of borrowers as exogenous shocks that reveal information on environmental risk, we find that lenders manage borrowers’ environmental risk by conventional tools such as imposing higher interest rates, utilizing financial and net worth covenants, showing reluctance to refinance, and demanding increased collateral. In contrast, the inclusion of sustainability pricing provisions in loan agreements for high environmental risk borrowers is reduced by 11 percentage points. Our study suggests that sustainability pricing provisions may not primarily serve as risk management tools but rather as instruments to attract demand from institutional investors and facilitate secondary market transactions.

Regulating Zombie Mortgages

Jonathan Lee Duc Duy Nguyen Huyen Nguyen

in: IWH Discussion Papers, Nr. 16, 2024

Abstract

Using the adoption of Zombie Property Law (ZL) across several US states, we show that increased lender accountability in the foreclosure process affects mortgage lending decisions and standards. Difference-in-differences estimations using a state border design show that ZL incentivizes lenders to screen mortgage applications more carefully: they deny more applications and impose higher interest rates on originated loans, especially risky loans. In turn, these loans exhibit higher ex-post performance. ZL also affects lender behavior after borrowers become distressed, causing them to strategically keep delinquent mortgages alive. Our findings inform the debate on policy responses to foreclosure crises.
