Primary academic paper
Khoo & Tallarita (2025).
Kenneth Khoo & Roberto Tallarita, The Price of Delaware Corporate Law Reform (2025), SSRN No. 5318203, papers.ssrn.com/abstract=5318203 OK
Supports all headline replication targets: the K-T event date (Feb. 18, 2025), the DE-indicator coefficient (≈ −1.4% over [−1,+5]), the blockholder cross-section (>15% block ≈ −1.6%), and the dual-class coefficient (≈ −2.4%), all from K-T Table 5 / Table 7 and abstract.
Authorship. Lead author Kenneth Khoo (National University of Singapore, Faculty of Law); co-author Roberto Tallarita (Harvard Law School). The paper was posted to SSRN on June 24, 2025, and circulated on the Harvard Law School Forum on Corporate Governance (Aug. 4, 2025); it is not listed in the Harvard John M. Olin Center Discussion Paper Series, so the neutral SSRN form is used and the Olin-series attribution is dropped. Prior internal references to "Kahan & Tornetta" or "Kobi Kawai Khoo" were errors and are corrected.

Kahn v. M&F Worldwide Corp., 88 A.3d 635 (Del. 2014). Opinion: Justia OK
Note on legal direction. Match reaffirmed the strict MFW double-cleansing standard (independent committee and majority-of-minority approval) that SB 21 then displaced for many controller transactions. The 33⅓% controlling-stockholder threshold in amended DGCL § 144 is a new statutory creation, not derived from the MFW / Match line.

Citation discipline notes
- K-T means Khoo–Tallarita. Prior internal references to "Kahan & Tornetta" or to "Kobi Kawai Khoo" were errors and are corrected. The paper is cited in the neutral SSRN form; it is not in the Harvard Olin Discussion Paper Series, so that attribution is not used.
- Harvey-Liu-Saretto-Pontiff (2020) is volume 10, issue 2 of the Review of Asset Pricing Studies (not volume 33). Four authors; Pontiff was previously omitted in some drafts.
- Rosenbaum (2002) Observational Studies and Rosenbaum (2010) Design of Observational Studies are separate books, not reprints. Γ-sensitivity appears in both; this project cites the 2002 work for the procedure.
- TBOC § 21.373 is the SB 1057 shareholder-proposal threshold, not exclusive-forum. Confirmed against the SB 29 enrolled text and SB 1057 sources: SB 29's exclusive-forum / internal-entity-claim provision is § 2.115; § 21.373 (added by SB 1057) governs ownership/holding thresholds for shareholder proposals at nationally listed corporations.
- In re Match Group reaffirmed the strict double-cleansing MFW standard that SB 21 then displaced. Match did not "extend" or "reaffirm" the 33⅓% controller threshold, which is a new statutory creation in amended DGCL § 144.
- SB 21 event-date anchor. Delaware's official bill page shows introduction on Feb. 17, 2025. The Feb. 18, 2025 anchor used by Khoo & Tallarita is the first broad market-public signal; the pinned market source for that date remains to be fixed.
- SB 29 effective date. Signed May 14, 2025 and effective immediately under Tex. Const. art. III, § 39 (verified against the enrolled text). The September 1, 2025 effective date belongs to companion bills (SB 1057 / SB 2411).
