Exoneration Finance, Kay L. Levine, Russell M. Gold

Faculty Articles

The path to financial compensation for the wrongfully convicted can be complex and time-consuming. Exonerees often struggle to make ends meet and function in free society, let alone navigate serpentine processes while waiting years for the recovery they deserve. Securing the assistance of an attorney is often a critical step, but too few lawyers are willing to risk accepting these complicated cases on a contingency-fee basis—the only way that exoneree-clients can likely pay their lawyers without outside help.

Litigation finance—an important tool for increasing access to justice in tort cases—could help close this access to justice gap for exonerees. In …

Narrative Economics As The Origins Of Momentum, Aung Khant Myat

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study investigates the role of economic narratives in shaping momentum effects in U.S. equity markets from 1984 to 2017. Utilizing narrative attention measures developed by Bybee et al. (2024), we examine how narrative attention and narrative innovation influence both time-series and cross-sectional momentum returns, after adjusting for Fama-French factors. LARS is employed for variable selection, and rolling-window regressions are used to capture time-varying factor loadings. Through a combination of time-series and panel data analysis, we test hypotheses related to static, persistent, and asymmetric narrative effects, along with firm- and market-level moderators. While the results are mixed across subsamples and …

Does Esg Performance Influence Cash Holding Behavior? Evidence From Asia-Pacific Firms, Khin Sandy Kyaw

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study explores the relationship between Environmental, Social, and Governance (ESG) performance and corporate cash holdings among publicly listed firms in the Asia-Pacific region from 2010 to 2023. Grounded in stakeholder theory and the precautionary motive for cash, the analysis examines whether firms with higher ESG performance hold less cash and whether this relationship is moderated by financial constraints and financial distress. Employing panel fixed-effects regression, two-stage least squares (2SLS), and system GMM methods, the results consistently indicate that ESG performance is negatively associated with cash holdings. The moderating analyses reveal that financially constrained or distressed firms with high ESG …

Growth Stock Performance: Analysts And Investors, Klah Kanittanon

Chulalongkorn University Theses and Dissertations (Chula ETD)

This research study examines the earnings growth expectations for growth stocks from the perspectives of investors and analysts. Portfolios were categorized based on the earning growth expectations of investors and analysts, with returns measured using the Fama-French Three-Factor Model from 2011 to 2023 in the U.S. stock market. The portfolio returns based on analysts' expectations were significantly positive, indicating that analysts tend to underestimate earnings growth for growth stocks. In contrast, the portfolio returns based on investors' forecasts were close to zero and not statistically significant, implying that investors do not systematically overestimate or underestimate earnings growth expectations for growth …

A Customized Compartmental Epidemiological Model With Vaccination Groups For Covid-19 And Its Application To Pricing Pandemic Insurance Policies, Om Kanchanasakdichai

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study presents an agent-based modeling framework designed to evaluate epidemic-responsive insurance mechanisms under behavioral and supply-side constraints. The model does not rely on empirical calibration or external datasets; instead, it explores how stylized agent behavior and systemic pressures jointly influence insurance uptake, coverage efficiency, and policy outcomes. The simulation integrates a stochastic SEIR+ disease progression structure with individual-level decision making shaped by perceived risk salience, scarcity sensitivity, and delayed response behavior. A two stage evaluation process is implemented: first, a global sensitivity analysis identifies the key drivers of agent and system behavior; second, a strategic policy simulation compares the …

The Impact Of Esg Performance On Equity Mispricing: Evidence From Asia-Pacific Markets, Visut Poochum

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study examines the relationship between ESG performance and equity mispricing in Asia-Pacific markets from 2010 to 2023, using the Rhodes-Kropf et al. (2005) decomposition method. The results show that stronger ESG performance is significantly associated with lower mispricing, particularly among undervalued firms, suggesting that ESG improves pricing efficiency by reducing information asymmetry. ESG performance has limited influence on overvalued firms, indicating its impact is more pronounced when valuations are suppressed. Further analysis reveals that the environmental, social, and governance pillars each independently contribute to mitigating mispricing, highlighting their distinct roles in enhancing pricing accuracy. ESG controversy does not significantly …
