The critique literature did not develop on a single track. One branch asked how Delaware corporate law works as an institution, independent of whether market prices register state-law differences. Edward B. Rock's 1997 piece in the UCLA Law Review, Saints and Sinners: How Does Delaware Corporate Law Work?, treats Delaware fiduciary opinions as devices for transmitting social norms to managers, directors, and the lawyers who advise them — the lawmaking function rather than the rule-announcement function.38 Jill E. Fisch's 2000 piece in the University of Cincinnati Law Review, The Peculiar Role of the Delaware Courts in the Competition for Corporate Charters, extended the same insight: Delaware's competitive advantage lies less in the substance of its corporate code than in the lawmaking process — judge-made, flexible, responsive — by which that code is produced and updated.39
A parallel branch challenged the empirical claim that Delaware law produced a measurable value premium. Marcel Kahan and Ehud Kamar's 2002 piece in the Stanford Law Review, The Myth of State Competition in Corporate Law, argued that the Cary-Winter race framing rests on an empirical premise — that states actually compete with one another for incorporations — that the data do not support. States other than Delaware, Kahan and Kamar showed, attract few public-company incorporations regardless of the corporate code they offer.13 Lucian Bebchuk and Assaf Hamdani made the parallel argument the same year in the Yale Law Journal, Vigorous Race or Leisurely Walk: Reconsidering the Competition Over Corporate Charters, observing that no state has been giving Delaware a serious run for its money — undermining the rivalry premise on which the Winter race-to-the-top mechanism depends.40 The empirical critique sat on top of a theoretical foundation Bebchuk had laid a decade earlier in the Harvard Law Review: Federalism and the Corporation: The Desirable Limits on State Competition in Corporate Law (1992) had already identified the conditions under which managerial opportunism and externalities cause state competition to fail, and had advocated targeted federal regulation as the response.41 Lucian Bebchuk, Alma Cohen, and Allen Ferrell offered a foundational empirical critique of Daines that same year in the California Law Review, arguing that the Tobin's-Q methodology Daines deployed was unreliable as a measure of the value effects of corporate law.14
A decade later, Robert Anderson IV and Jeffery Manns published The Delaware Delusion in the North Carolina Law Review, arguing that the Delaware premium reported in earlier work was largely an artifact of selection — high-quality firms were more likely to incorporate in Delaware, but Delaware did not make them high-quality firms.15 Anderson followed in 2018 with a companion empirical piece, The Delaware Trap, in the Southern California Law Review.16 Robert Bartlett and Frank Partnoy completed the methodological consolidation in 2020 with The Misuse of Tobin's q in the Vanderbilt Law Review, showing that the Tobin's-Q metric on which much of the Delaware-premium literature rested was systematically mis-measured in ways that biased the empirical results.17
By 2020, the methodological consolidation was complete. The empirical case for Delaware mattering had not been disproven — the underlying agency-problem motivation Berle and Means had identified in 1932 had not gone away — but the strongest empirical claims of the Daines era had been substantially undermined. Two further pieces from this period reframed the agency problem itself rather than the empirical machinery used to test it. Ronald Gilson and Jeffrey Gordon's 2013 piece in the Columbia Law Review, The Agency Costs of Agency Capitalism: Activist Investors and the Revaluation of Governance Rights, observed that the Berle-Means picture of dispersed individual shareholders had been replaced by reconcentrated ownership in institutional intermediaries, generating a new layer of agency costs between record owners (institutions) and beneficial owners — a structural change that conditions every Phase 8 question about who actually votes the shares of an SB 29-electing or DGCL §144-cleansing firm.42 Lucian Bebchuk and Roberto Tallarita's 2020 piece in the Cornell Law Review, The Illusory Promise of Stakeholder Governance, supplied the period's most cited critique of the corporate-purpose alternative to shareholder primacy, advancing the empirical and conceptual case that a stakeholder-governance regime would impose unmanageable trade-offs on directors without producing meaningful gains for the constituencies it nominally serves.43 Marc I. Steinberg, Rupert and Lillian Radford Chair at SMU Dedman School of Law, supplied the long-form historical treatment of a parallel trajectory in his 2018 Oxford University Press book The Federalization of Corporate Governance, with a companion 2019 piece in the Loyola University Chicago Law Journal, The Federalization of Corporate Governance — An Evolving Process, arguing that federal regulation has steadily encroached on state-law fiduciary doctrine and that the federalization process is a more important determinant of corporate-law content than interstate competition.44
Two further pre-Phase-8 contributions supply theoretical scaffolding that the post-Tornetta debate either reacts to or relies on. Henry Hansmann and Reinier Kraakman's 2001 piece in the Georgetown Law Journal, The End of History for Corporate Law, articulates the global-convergence thesis — that the shareholder-oriented model has won the comparative-corporate-governance debate and that surviving state-level variation is best read as transitional rather than enduring — and supplies the dominant position that the Phase 6 through Phase 8 controller-primacy, segmentation, and DExit literatures later cut against.56 Mark J. Roe's 2003 piece in the Harvard Law Review, Delaware's Competition, reframes the race-to-the-bottom versus race-to-the-top debate by identifying Washington, D.C. — not Nevada or Texas — as Delaware's most consequential competitor, because the binding constraint on state corporate law is the federal pre-emption posture of Congress, the SEC, and the federal courts.57 Roe's vertical-federalism frame is the missing third leg of the Cary-Winter axis and bears directly on Phase 8 because it explains why DExit is structurally possible at all: Washington has not intervened, and the silent federal backdrop is what allows interstate competition to operate as the visible margin.

The vertical band marks the post-Tornetta moment. Each marker is the doctrinal entry-point for one of the eight phases above; the color encodes the debate camp it founded or extended.
How to read. The horizontal axis is calendar time; markers above and below the axis alternate purely for legibility. The red dashed vertical at January 2024 marks the post-trial Tornetta v. Musk opinion that serves as the temporal anchor for the Delaware-Exit episode tracked on this site. Bartlett-Partnoy (2020) is the methodological consolidation point that closed the Daines / Subramanian empirical-premium debate; Rhee (2023) and Bebchuk & Kastiel (2026) bracket the post-Tornetta camps.
