What's Your Bank's Fintech Score? Technology Integrating Banking into the Broker Intermediation Model with Linda Allen (Baruch College), Yu Shan (Syracuse University) and Yi Tang (Fordham University) (Journal of Financial Services Research, 2025)
Abstract:
We define FinTech as banks’ integration of technology into the broker intermediation model. Unlike traditional dealer banks relying on leveraged balance sheets for intermediation, FinTech banks adopt a technology-driven broker model. Using nonlinear and machine learning algorithms, we develop an empirical “FinTech score” that shows on-balance sheet lending for low-FinTech-score banks versus securitization, brokered deposits, and non-interest income for high-score banks. Using two complementary measures of operational efficiency, we find that this technology-driven shift in business models (either holistically or via mergers) helps explain reductions in the cost of financial intermediation. Our bank-specific, time-varying FinTech score provides insights into the distribution of FinTech integration into U.S. banking. Link to paper
Measuring Systematic Risk from Managerial Organization Capital with Linda Allen (Baruch College) (Journal of Business Finance and Accounting, 2021)
Abstract:
Organization capital (OC) constitutes a firm’s unique, hard-to-mimic, hard-to-transfer culture, internal knowledge and language, policies and procedures, growth opportunities and information technology, brand name and any other aspects that are not directly related to the production process. In order to disentangle value enhancement from agency costs inherent in the OC, we calibrate systematic risk premiums from the loss of managerial OC rents by decomposing OC into: (1) portable economic rents in the form of disclosed executive compensation and (2) a strategic component comprised of undisclosed, non-portable OC rents mixed with agency costs. Shareholders in firms with high strategic component (not the portable component) earn an annual systematic risk premium of 4.6%. Disclosures revealing the breakdown between OC and agency costs in the strategic component (earnings surprises, managerial obfuscation and stock mispricing) as well as corporate governance eliminate this risk premium by revealing the OC rents in strategic component and increasing OC portability.

The Effect of Relationship Banking on Firm Efficiency and Default Risk (Journal of Corporate Finance, 2020)
Abstract:
Does relationship bank oversight reduce firm default risk and improve firm operational efficiency? I find that a new loan from a relationship bank reduces the default probability and increases the efficiency of a borrowing firm, benefiting both banks and borrowers. Moreover, inefficient and less creditworthy firms experience the highest reductions in their default risks and improvements in their efficiencies in the years following new relationship bank loans. Further, these benefits are disrupted when the relationship bank is acquired. Link to paper

Organizational Exposure to Generative AI and Its Impact on Employee Satisfaction with Dogukan Yilmaz (INSEAD) and Milan Miric (USC) (Under review)
Abstract:
Generative Artificial Intelligence (GenAI) has the potential to transform many industries and is exposing workers in a variety of organizational roles to uncertainty about the future of their position. Using data from Glassdoor reviews, we investigate how the introduction and diffusion of this technology influences worker satisfaction and find evidence of a significant decrease in satisfaction. We find that this decline is concentrated in firms with high GenAI exposure following the release of ChatGPT. This effect is driven by increased job uncertainty and anxiety, evidenced by text analysis of employee reviews, rather than by immediate changes in productivity. The negative impact is significantly more pronounced in smaller, less profitable firms and, paradoxically, within the technology sector.
Financed Emissions and Banks' Lending Porfolios with Elsa Allman (Banque de France), Sonali Hazarika (Baruch College) and Mo Qiao (Baruch College) (Under review)
Abstract:
This paper examines how the Paris Agreement affected the financed emissions of banks’ syndicated loan portfolios. Focusing on 233 banks across 40 countries from 2010–2023, we distinguish between portfolio decarbonization through divestment from high-emitting borrowers and engagement via post-loan origination monitoring. We find that Brown banks—those with high pre-Paris exposure to energy-sector lending— significantly reduce the financed emissions from newly originated loan portfolios after Paris, with declines of 12.6% in relationship lending portfolios and 20% in nonrelationship portfolios, relative to the mean logged values of the respective portfolios. These reductions are concentrated in the energy sector and driven by a lower share of energy sector borrowers, reallocation toward cleaner new borrowers and the formation of new relationships with cleaner borrowers. By contrast, we find little evidence of engagement: financed emissions do not decline through post-loan origination monitoring, including within relationship lending portfolios. Moreover, the effects are not driven by ESG-oriented institutional investors, green bond issuance, borrower-country carbon pricing, or voluntary climate initiatives. Overall, the Paris Agreement induced selective portfolio decarbonization driven by changes in lending flows rather than sustained
engagement with existing clients.
