WORKING PAPERS

  1. Revisiting the Missing R&D-Patent Relation: Challenges and Solutions for Firm Fixed Effects Models (with Po-Hsuan Hsu, Chung-Ming Kuan, and Jui-Chung Yang)[ssrn][slide][code]
    The SFS Cavalcade Asia-Pacific 2024; 2024 UC Davis-FMA Napa Finance Conference; Max Planck I&E Seminar*; 16th NYCU Finance Conference (Keynote)*; 2024 FMA Asia Pacific Conference. (*Presented by Po-Hsuan Hsu)
    Abstract
    The common practice of including firm fixed effects in empirical researzch may eliminate the explanatory power of important economic factors that are persistent. We use the intuitive R&D–patent relation to illustrate this point. Our review of recent studies suggests a surprising pattern: R&D input positively explains patent output in only half of prior regression estimations. This “missing link” can be attributed to the persistence of R&D and patents, which allows between-firm variation to be absorbed by firm dummies. We consider adjusted Hausman–Taylor estimates and advanced machine-learning methods, both of which restore a clear positive R&D–patent relation. Notably, ML models reveal that only 10-20 % of firm dummies are informative; including the rest biases identification. The paper offers two ready-to-use econometric “second opinions” for researchers dealing with explanatory variables that strongly correlate with between-individual unobservables.
  2. Classifying Hedge Fund Strategies with Large Language Models: Systematic vs. Discretionary Performance (with Chung-Ming Kuan)[paper][slide]
    European Financial Management Association 2025 Annual Meeting, Greece; Quantitative Finance Workshop 3 (Asset Pricing & Risk Management), IMS-NUS, Singapore; 26th Conference on the Theories and Practices of Securities and Financial Markets.
    Abstract
    We fine-tune FinBERT, a finance-specific large language model, to classify hedge funds as systematic or discretionary. Removing manual subjectivity yields cleaner style labels and reveals that systematic funds, on average, generate higher factor-adjusted returns than discretionary funds. After a false-discovery-rate adjustment, 10-20 % of funds still show statistically significant positive alphas in models that include both observable and latent risk factors.
  3. What Share of Patents Is Commercialized? (with Po-Hsuan Hsu, You-Na Lee, and John P. Walsh)
    TPRI Brownbag Seminar*; NBER Productivity Seminar*; Max Planck I&E Seminar*; TES 2023; Academia Sinica; NTU; NTPU; YZU. (*Presented by John P. Walsh)
    Abstract
    Using three independent inventor surveys as labeled data, we combine contextual embeddings (BERT for Patents) with bibliometric indicators to build machine-learning models that estimate, over time and at scale, the probability that a US patent is commercially exploited. The approach reveals commercialization rates across technologies and cohorts that were previously impossible to observe.
  4. Assessing Risk Spillovers with (Lasso) VAR for Expectile (with O-Chia Chuang, Zaichao Du, and Zhenhong Huang)
    28th Conference on the Theories and Practices of Securities and Financial Markets; NTU; TFA 2020; TES 2020; 6th Annual Meeting of Young Econometricians in Asia-Pacific*. (*Presented by O-Chia Chuang)
    Abstract
    We generalize the vector autoregressive (VAR) model from conditional means to conditional expectiles (MCARE) for assessing risk spillovers among multiple entities. For high-dimensional systems, we impose an L1 penalty (L-MCARE). Applied to the return network of global systemically important banks, MCARE and L-MCARE uncover time-varying tail-risk transmission patterns.
