Does Generative Ai Facilitate Investor Trading? Evidence From Chatgpt Outages, Qiang Cheng, Pengkai Lin, Yue Zhao

Research Collection School Of Accountancy

In this paper, we use ChatGPT outages to investigate whether investors rely on generative artificial intelligence (GAI) to perform trading-related tasks and the associated impact on stock price informativeness. We first document a significant decline in stock trading volume during ChatGPT outages and find that the effect is stronger for firms with corporate news released immediately before or during the outages. We further document similar declines in the short-run price impact, return variance, and bid-ask spreads, consistent with a reduction in informed trading during the outage periods. Lastly, we use trading volume changes during outages to construct a firm-level measure …

This paper employs a mixed research method, incorporating both qualitative and quantitative analyses to ensure comprehensive coverage of the topic. First, it outlines the theoretical basis and development of non-financial factors in investment decisions through a review of prior literature. Next, it collects …

Stock Market Volatility In The United Kingdom: Simulating Post-Covid-19 Recovery, Bala A. Dahiru, Mohammed Shuaibu, Najibullah Hassanov

CBN Journal of Applied Statistics (JAS)

This paper investigates the time it would take for the FTSE-100 index to reach its post-COVID-19 peak. The paper utilises an exponential generalised autoregressive conditional heteroscedasticity (EGARCH) model that accounts for leverage effect and asymmetries. The preferred models amongst competing variants was the Autoregressive Moving Average (ARMA)-EGARCH(2,1) specification and was used to predict daily FTSE-100 data from 5th January 2000 to 21st June 2024. The empirical exercise showed that the COVID-19-induced financial crisis negatively affected the United Kingdom’s stock market performance. The results show that the FTSE100 index could reach its post-pandemic peak around 27th August, 2024 (two months after …

Impact Of Fiscal Policy On Financial Inclusion And Development In Nigeria, Okwanya Innocent, Taiwo A. Olusegun, Aimua E. Peace

CBN Journal of Applied Statistics (JAS)

This paper examines the effect of fiscal policy on financial inclusion and development in Nigeria. The study employs the Autoregressive Distributed Lag (ARDL) model and impulse response function (IRF) to determine the extent and response of financial inclusion and development to fiscal policy changes in Nigeria. The study derives a financial inclusion index from three core indicators: access, usage and quality of financial services, while financial development is measured as the ratio of money supply to GDP (M2/GDP). The results show that government expenditure has a significant positive effect on financial inclusion and development, while tax revenue exerts a negative …

Politically Connected Emncs In A (De)Globalising World: A Review And Future Research Directions, Dongdong Huang, Lai Si Tsui-Auch, Marleen Dieleman, David Gomulya

Research Collection Lee Kong Chian School Of Business

Emerging market multinational corporations (EMNCs) have emerged as significant global players, driven by their home country political connections that present both opportunities and challenges. Despite the insights gained from current studies, we still lack a clear conceptualisation of diverse political connections and the distinctiveness of politically connected EMNCs. Our study conducts a comprehensive review to bridge those gaps. We identify and compare two types of political connections, delve into major theories and highlight their main focus, key arguments, mechanisms and outcome predictions. Consequently, we propose a context-mechanism-outcome framework across three contextual levels, emphasising theoretical convergence and divergence between politically connected …

Tied Together With Ticketmaster: Analyzing The Exclusive Contracts Of Ticketmaster Through The Lens Of Antitrust Scholars, Jenna Gillam

Honors Projects

The Eras Tour Verified Fan Sale in 2022 revealed major flaws in the ticket-buying process, which many attributed to Ticketmaster's dominant industry position. The exclusive contracts of Ticketmaster have been their source of gaining a competitive advantage in the ticketing industry, but many have been critical of these contracts for restricting competition in this industry. This research analyzes the effect of the exclusive contracts of the merged Ticketmaster-Live Nation entity on competition in the ticketing industry through the lens of prominent antitrust scholars. Previous literature reveals differing ideas about whether exclusive contracts are an exclusionary practice and literature identifies the …

Digital Currencies And Macroeconomic Performance: A Global Perspective, Tirimisiyu F. Oloko, Ahamuefula E. Ogbonna, Idris A. Adediran

Bulletin of Monetary Economics and Banking

In this study, we explore the IS-LM-BP framework in analysing the effect of digital currencies on macroeconomic performance from a global perspective. We augment the global macroeconomic dataset by Mohaddes and Raissi (2020) with digital currencies, and analyse the relationship between 2010Q1 and 2019Q4. Overall, we find digital currencies to have significantly positive short-run and no long-run impact on global output, inflation rate, interest rate, and equity stock return. Our results suggest that digital currencies have enhanced global macroeconomic performance, on average. Thus, we recommend that appropriate regulations, rather than an outright ban on digital currencies, should be implemented.

3rd Sbs International Conference 2025: Innovation And Disruption: Business Success Through Ai, School Of Business Studies (Sbs)

Conference Proceedings

From the time that Clayton Christensen (1997) highlighted the concept of disruption due to innovation, and its impact on businesses and economies, practitioners and researchers have diverted their attention to the evil it casts and the opportunities it presents. Innovations and improvements in technologies have more often than not resulted in disruption of business models prevalent at that time. The three industrial revolutions have marked definitive shifts in performance and perspectives, and now the world awaits the outcome of the industrial revolution 4.0. Disruptions do not come only from revolutions. This is evident from the very recent incidence of the …

No Time For Tea: Hidden Figures Of The Dutch Tea Industry, Annette Kappert, Lysbeth Vink

Dublin Gastronomy Symposium

This paper explores the historical role women played in promoting, distributing, and establishing tea consumption in The Netherlands. Despite being the first nation to introduce tea to the Western world, and the abundance of literature and images documenting women as sapless tea drinkers, languishing their afternoons away, entertaining and sipping the amber brew in their tea houses, the latter is far from reality. Preliminary research indicates Dutch women were instrumental in establishing an elite tea industry in The Netherlands and beyond. Aptly the authors utilized the archives to explore visual and narrative data dating from 1610 to present, to find …

Latin American Participation In The Current Process Of Economic Globalization, Sullivan D. Padgett

Journal of Global Awareness

From World War II to the present, Latin America has participated in the current process of economic globalization to varying degrees. The Washington Consensus of the late twentieth century supplanted the region’s earlier model of state-led development and increased its participation in the global capitalist regime. However, Latin America has shown minimal participation in the current process of economic globalization since the late 2000s and, instead, espouses regionalization. Nevertheless, regionalization has proven to be an arduous undertaking in Latin America, especially with China’s increasing regional influence. Variations of benefits are discussed, and recommendations are offered. While the future of Latin …

Exploring The Relationship Between Load Shedding And Crime In Gauteng, Bhavesh Ram

Master's Theses

This study investigates the impact of load shedding, a recurring power outage phenomenon in South Africa, on crime rates in the densely populated Gauteng province. Using a novel dataset that combines Eskom's load shedding schedules with detailed crime statistics from 2015 to 2022, a fixed-effects regression model is employed to examine the relationship between blackout hours and various crime categories. Findings reveal that while load shedding does not significantly affect overall crime rates, it significantly increases the incidence of contact crimes and sexual offenses, particularly during daylight hours. Additionally, our results provide evidence that load shedding diminishes the ability of …

Beneath The Mask: The Performance Of Blackness And Economies Of Caricature In American Fiction, Terri Bowles

Markets, Globalization & Development Review

In American Fiction (2023), written for the screen and directed by Cord Jefferson, satire, drama and comedy frame a knife-sharp examination of America’s cultural reproductions of stereotype and caricature. The film, based on Percival Everett’s novel Erasure, explores the fraught professional position of Thelonious “Monk” Ellison (Jeffrey Wright), a professor-author pressed to write a bestseller amid family upheaval and financial strain. Monk’s resulting novel, a gritty send-up of urban tropism drafted in a fit of fury and frustration, exploits America’s fixation on commodifying and flattening Blackness—and becomes an instant hit. This review explores the film’s interrogations of race, class and …

Can Marketing Transcend Entrenched Gender Biases?, Thinh Nguyen

Markets, Globalization & Development Review

Through a feminist lens, Maclaran and Chatzidakis (2022) challenge conventional assumptions about gender, emphasizing its performative nature shaped by social practices rather than inherent traits. This commentary extends analyses of key themes such as gender performativity, the male gaze, and subject-object binaries within marketing. It critiques how marketing strategies reinforce existing power imbalances and systemic biases rooted in historical narratives. The writing also reflects on media interpretations of gender issues through films like 'Turning Red' and 'Barbie'. By contextualizing gendered marketing within broader societal frameworks, this writing contributes to ongoing dialogues in media studies, sociology, and gender studies, highlighting the …

Specifying And Estimating Vector Autoregressions Using Their Eigensystem Representation, Leo Krippner

Sim Kee Boon Institute for Financial Economics

This article introduces the principles and mechanics of the eigensystem vector autoregression (EVAR) framework, where a VAR may be specified and estimated directly via its eigenvalue and eigenvector parameters. Using explicit constraints on the eigensystem permits control of a VAR ís allowable dynamics, which is illustrated empirically with standard and time-varying VAR estimations specified to be always non-explosive.
