Title: Uncertainty Creates Zombie Firms: Implications for Industry Dynamics and Creative Destruction

Joint with Kevin Aretz (University of Manchester), Murillo Campello (Cornell University and NBER), and Gaurav Kankanhalli (University of Pittsburgh)

Guest speaker: Kevin Schneider (Cambridge)

Abstract: We show how the threat of “uncertainty-induced zombification” — creditors’ willingness to keep their distressed borrowers alive when faced with uncertainty — shapes various industry dynamics. Under areal options framework, we demonstrate that unlevered firms become reluctant to invest and disinvest in anticipation that uncertainty induces creditors to convert defaulting rival firms into zombies. We validate our theory using dynamic, industry-specific estimates of uncertainty-induced zombification together with loan contract-level data. Empirically, higher uncertainty-led rival zombification prompts healthy firms to reduce their costly-to-reverse capital investment and disinvestment, hiring, and establishment-level openings and closures (intensive and extensive margins are affected). We confirm those dynamics using granular, near-universal data on the asset allocation decisions of global shipping firms. Critically, uncertainty-led zombification depresses healthy firms’ long-run sales, profits, and stock returns. Our results reveal nuanced effects on creative destruction — while healthy firms’ asset reallocation slows down, their innovation activity accelerates. Our findings highlight a novel channel through which uncertainty shapes firms’ capital accumulation, distorting their real and financial policies and performance.

Title: Temperature Exposure and Green Revenues of Firms Around the World

Guest speaker: Panagiotis Tzouvanas (Portsmouth) 

Abstract: This paper examines the temperature anomaly exposure of firms around the world. We construct temperature beta using Asset Pricing Models, incorporating countries’ temperature anomaly as an additional factor. We document that the transmission mechanism by which temperature anomalies affect stock returns is through the channel of cash flows and profitability. Such we find a statistically significant and negative temperature beta. In addition, we explore hedging mechanisms to mitigate temperature risk exposure, and our findings suggest that firms engaged in green activities, as measured by green revenues, demonstrate resilience to temperature risk. Also, low temperature exposure stocks generate around 1% more annualised returns compared to stocks in the highest temperature exposure decile. Finally, there is a significant temperature risk premium associated with buying negative climate beta stocks and shorting positive ones, estimated at a rate of 1.32%.

Title: The Cost-based Value Chain Analysis (CVCA): A Proposal to Tax Business Profits in the Global Economy

Abstract: Digitalisation in international business value chains has exacerbated the misattribution of taxable profits and base erosion into low-tax jurisdictions. Recent responsive proposals discriminate across types of digital activities and misrepresent synergy within the global business group, thereby worsening misattribution. International business tax literature across economics, law, and policy disciplines neither clarifies profit valuation at source in a synergistic value chain nor provides a practical consensus on profit allocation. We still do not have a baseline to assess the misattribution of multinational taxable profits.

How, then, should host tax jurisdictions share the global business profits tax base? This thesis proposes that the taxable profits of a global business group should be allocated in neutral proportions to business activities across all host tax jurisdictions. Taxable proportions should be neutral across the types of business activity, level of digitalisation, and location. The thesis extends the international business tax literature using an interdisciplinary tax theory and management accounting approach to craft a new definition for misattribution, coined as inter-input equity, and to design the Cost-based Value Chain Analysis (CVCA) to allocate multinational taxable profits. Inter-input equity requires that business activities of the same type receive similar proportional allocations of taxable profits across the multinational business group, regardless of geographic value chain position or extent of digitalisation. This baseline establishes a midpoint between ad hoc origin-based valuation of business activity and cumulative division of the profits tax base between host tax jurisdictions.

The inter-input equitable CVCA measures business activities using costs, derives a consolidated markup of profit by cost per business group taxpayer, and delivers relative and substantive equality of jurisdictional tax rights with minimal distortion to business decisions. Finally, the thesis develops an interdisciplinary evaluation framework to compare the CVCA against the market-based and formulary apportionment proposals by integrating tax rights fairness, efficiency, neutrality, and administrability criteria.

Title: Fintech and green finance in banking: the interplay of geographic dispersion and bank governance

Abstract: Both fintech and green finance are central themes in the ongoing international discourse on banking sector development, yet they are generally treated as separate in academic research. This study connects fintech and green finance by exploring the potential of fintech in facilitating banks’ engagement in green finance. We introduce a novel measure for assessing geographic dispersion of bank branches and investigate how the impact of fintech on green finance activities is related to geographic dispersion and its interplay with bank governance. Drawing upon a sample of all listed banks in China over the 2010-2022 period, we find that fintech negatively affect green lending participation of geographically more dispersed banks. However, when accompanied by effective bank governance, even highly dispersed banks can unlock the supporting effect of fintech on green lending. Our results are robust after employing alternative measures for fintech and green finance engagement, a subsample, and an instrumental variable approach. This study represents the pioneering attempt to link geographic dispersion and bank governance with banks’ dynamic capabilities. The findings hold important implications for banks aimed at implementing a green and responsible strategy: to leverage fintech-enabled green finance, banks particularly those with a wider geographical presence should further enhance their corporate governance practices to cultivate stronger dynamic capabilities that facilitate effective deployment of fintech.

Title: Opening the Brown Box: Production Responses to Environmental Regulation

Abstract: We study production responses to an emission capping regulation on manufacturing firms. Firms reduce pollution by electrifying their production, producing less coal-intensive products, and increasing their abatement expenditures. Firms preserve profitability by increasing their production of higher-margin products. However, firms in highly polluting industries produce fewer products. In the aggregate, we document lower product variety, an altered firm-size distribution, and lower business formation. Our findings highlight the mechanisms behind how mandated pollution reduction can be effective and its costs, suggesting a loss in agglomeration externalities.

Title:  Can Markets Save Nature?

Abstract: In recent years, the need for the private sector to step up has become the dominant narrative in the increasingly desperate calls for more investments into nature. A range of financial instruments are available, but financial flows remain stubbornly low. This leads us to ask if private investments in nature are possible or a chimera? We create a simple architecture to probe this question and argue that in the absence of strong supportive policy signals private investors are likely to be a better fit for projects on the demand side of natural capital where nature investments can be tagged onto other activities. These represent 60% of nature investment needs thus highlighting a significant potential, but also compellingly show the need for governments– both to supply the remaining funding and to provide the required conditions to attract private investors. 

Speaker bio: Pernille Holtedahl is a Research Fellow at the Centre for Climate Finance and Investment at the Imperial College Business School.

Title: Does the level of managerial competence lead to higher CEO over-payment?

Abstract: It is not uncommon to confuse top management’s, like CEO’s, performance with managerial compensation. CEO compensation is a complex function of many covariates. We model CEO compensation to include a comprehensive list of rewards and employ a novel model that nests a plethora of CEO- and firm-specific characteristics. Our model reveals for the first time CEO competence and it relates it with the probability of a CEO being overpaid or otherwise underpaid. Indeed, we provide exact figures of CEO’s over- and under-payment. The parameter estimates of our model is by no means an easy task and employ Bayesian estimation techniques to gain in accuracy and efficiency. There is variation in our results when we control for offering as part of CEO’s compensation ownership incentives such as stock options. We, also, reveal thresholds on both CEO competence and over-payment. Our model and results could inform regulators, shareholders, investors as well as CEOs on setting executives’ packages that reward talent, viz. competence in our model.

Title: "Digital Frontiers: Balancing Cybersecurity Risks in the Age of Digital Transformation"

Abstract: This study examines the relationship between digital transformation and exposure to cybersecurity risks at the firm level. The integration of advanced digital technologies can strengthen a firm’s cybersecurity capabilities, but it may also increase entry points for cyberattacks, potentially raising the firm’s overall cyber vulnerability. We empirically test this conjecture utilizing a matched sample of 9,606 U.S. firm-years spanning 2006–2023, including 543 documented cyber breaches, and find that greater digital transformation—as reflected in 10-K business descriptions—is positively associated with experiencing future cybersecurity breaches. Our empirical analyses reveal that a one standard deviation increase in digital transformation corresponds to a rise in future breach likelihood of up to 10 percentage points. We find that the exposure primarily stems from organizational, not technological, dimensions of digital transformation. Technologically competent auditors, boards, and operational officers mitigate cyber risk, but primarily for less digitalized firms. This study underscores the paradox of digital transformation, where technological innovation enhances business operations but simultaneously increases vulnerability to cyber threats, especially for highly digitalized firms. Our findings point towards adaptive and resilience-based cybersecurity approaches in highly digitalized organizations.

Guardians at the Gates: Home CEOs and Antitakeover Provisions”. 

Abstract: We examine the impact of CEOs’ home bias on antitakeover provisions driven by agency motivations. Firms led by home CEOs, implying heightened incentives to manage firms in their birthplace, are more likely to adopt ATPs. This effect is exacerbated in weak governance firms and high takeover threat environments. The adoption of state-level poison pill laws alleviates the impact of home CEOs on ATPs, suggesting that they serve as substitutes. These firms are associated with a lower likelihood of receiving bids and completing deals, a higher likelihood of withdrawn or completed in-state deals, reduced takeover premiums, and lower announcement returns.

Title: Are better ESG companies involved in more controversies?

Speaker: Markku Kaustia (Aalto)

Abstract: This paper is the first to examine how corporate environmental, societal and governance (ESG) measures are related to corporate controversies. To investigate this, we use Refinitiv data for 3,700 companies from Europe and the United States during the period of 2004 to 2021. We find that higher ESG ratings actually predict having more controversies in the future, up to two years ahead. The relationship is robust in US as well as Europe, and, in most specifications, it applies separately to each of the individual E, S, and G components. The results hold in several robustness checks such as splitting the dataset across time and by company type. We put forth the ESG salience hypothesis working through media attention as a plausible channel to account for these results.

Speaker bio: Markku Kaustia holds the Hannes Gebhard Professorship in Finance and Insurance at Aalto University, Finland. His research covers a broad spectrum of topics, including financial markets, investment strategies, behavioral finance, investor activity, household financial decisions, and investment behavior.

Title: Predatory Advertising, Financial Fraud, and Leverage

(This is a joint work with S Dasgupta, R Shi and J Yan)

Abstract: We examine how an industry leader’s competitors respond when financial fraud by the leader is publicly revealed. We document evidence of predatory advertising and pricing. Close competitors of the leader step up advertisement spending relative to control firms. Although we do not directly observe product prices, we find that even though advertisement increases, competitors’ profit margins drop, consistent with predatory pricing. Evidence of predation is stronger when rival firms have larger market share, the fraud firm has higher leverage, and when the average leverage of rival firms is lower. The effects appear mainly in industries that produce customized products and where consumer switching costs are high. Increasing advertising expenditure appears to be a more potent predatory strategy in industries that experience new customer growth, whereas cutting prices appears more potent in industries with stagnant customer base. We present a switching cost model similar to Klemperer (1995) that generates implications broadly consistent with these observations.

Speaker bio: Shantanu Banerjee is a Professor in the Accounting and Finance department of the University of Liverpool.

Environmental Penalties and Green Talk: evidence from conference calls (with C. De Amicis -Skema Business School) 

Abstract

This paper investigates how firms adjust their environmental disclosure strategies in response to environmental sanctions. Using natural language processing (NLP) techniques, we analyze the environmental content of earnings conference calls held by U.S.-listed firms from 2012 to 2022, focusing on changes around the announcement of environmental violations.

Our findings document a “Green Evasion Effect”, where CEOs talk less about environmental topics in calls immediately preceding the announcement of environmental penalties. This effect is stronger for firms that are  expected to uphold high environmental standards. Conversely, analysts increase their focus on environmental topics after the announcement, particularly for firms with higher environmental reputations. We further document that investors also respond negatively to environmental sanctions, with more pronounced market reactions for firms perceived as environmentally responsible.

Speaker bio: Sonia Falconieri is a Professor and the Head of Department of Finance and Accounting at the Bayes Business School, City University.

Title: “Contagion vs Competition: Evidence from Crypto Exchange flows”

(with D. Bianchi)

Abstract: The paper conducts an in-depth investigation into systemic risk within the cryptocurrency ecosystem by analysing inter-exchange flows before and after major disruptions, with a particular focus on the FTX bankruptcy. By disentangling the interplay between competition and contagion among cryptocurrency exchanges, we assess how such shocks propagate through the network, reshaping liquidity conditions and influencing the mechanisms of price discovery. Our analysis sheds light on the resilience of the crypto market, revealing the extent to which disruptions trigger liquidity fragmentation, price inefficiencies, and shifts in trader behaviour across interconnected exchanges.

Title: Heterogeneity in Investor Reaction to MNE’s ESG Incidents

Abstract: We study whether investors react differently to multinational enterprises’ (MNEs) ESG incidents across countries. We use a novel “Perception Index” to measure how domestic investors view other countries, based on their economic strength and legal power. Examining firms in 30 countries with the most ESG incidents for 2007-2022, we reveal heterogeneity in traders’ reaction to such incidents through cumulative abnormal returns (CAR). Guided by the Institutional Theory, we show MNEs face up to 0.9% greater negative daily CAR when investors perceive the incident country as legally and economically superior to others, including their home country. These findings document limits to “home bias”. Granular analyses indicate that neither severity and reach of incidents nor cultural aspects e.g., egalitarianism and trust, change investors’ trading behavior while religion seems to be a significant factor, and such heterogenous reaction is particularly evident for recurring cases and human rights incidents.

Speaker bio: Onur Tosun is a Reader (Associate Professor) in Finance and a Senior Fellow of the UK Higher Education Academy.

Title: Opportunistic Borrowing Before Default? A New Test Using Multiple Delinquent Credit Cards

Abstract: We investigate whether credit card holders borrow opportunistically prior to defaulting

on their credit card debt. Our analysis focuses on borrowers who go delinquent on multiple credit cards simultaneously, with some of them eventually being charged off. To control for all unobserved time-variant borrower-specific factors that influence delinquency and default, we then use borrower-by-billing-cycle (year-month) fixed effects. Under strategic default, we expect borrowers to opportunistically utilize available credit on the cards that are eventually charged off, relative to those that are not. Contrary to this expectation, we find that, if anything, users borrow less and repay more on the delinquent cards that are ultimately charged off. These findings suggest that either non-economic factors play a significant role in mitigating opportunistic borrowing in the credit card market or that people are seriously mistaken about the likelihood of their cards being charged off after delinquencies.

Speaker bio: Constantinos is an Associate Professor of Finance at Warwick Business School (WBS), where he began his tenure in 2013 as an Assistant Professor of Finance and Behavioural Science.

Title: Chasing Subsidies, Missing Effort: Disclosure Quality and Resource Misallocation in Chinese Firms

Abstract: Can increased competition for public resources deteriorate firms’ disclosure quality, thereby leading to the allocation of resources to undeserving firms? Using the departure of top provincial officials during China’s anti-corruption campaign as a shock to the competitive allocation of government subsidies, we find that firms are more inclined to excessively emphasize their investment in digitalization without making corresponding practical efforts (a phenomenon we term “Digitalwashing”). This effect is more pronounced among financially constrained firms, with weaker monitoring mechanisms and less political connection. Digital-washing enables firms to acquire additional government resources and attract more government customers despite showing no better performance than their peers. Our evidence supports legitimacy theory, indicating that firms enhance their public image through digitalization disclosures without substantively changing their underlying activities. This behaviour distorts the allocation of public resources, leading to no corresponding improvement in firm performance.

Cultivating Innovation: The Role of Outdoor Green Space in Corporate Green Innovation

Abstract

Using a unique dataset on land use in China, we find that the presence of parks and green areas within a 1-kilometer radius of firms’ geographic locations is positively associated with the number of green patents filed and their future citations. To address identification concerns, we employ matching approaches, two-stage least squares regression, high dimensional fixed effects, and placebo tests. Our path analysis shows that firms surrounded by green spaces are more likely to appoint CEOs and directors with environmental expertise and exhibit a greater strategic emphasis on innovation in corporate disclosures, both of which contribute to enhanced green innovation. The relation between green space coverage and green innovation is stronger for firms operating in highly competitive markets, with weaker pioneering innovation capabilities, higher business diversification, greater media coverage, and lower corporate social responsibility performance. These findings highlight the importance of urban green spaces in fostering corporate sustainability and innovation.

Speaker bio: Yeqin Zeng is currently an Associate Professor of Finance at Durham Business School. He earned his Ph.D. in Finance in 2013 from the Foster School of Business at the University of Washington.
