Dr Sonin is currently working on the monograph based on her doctoral research, Shareholders and stakeholders: the unrealised promise of company-law reform in post-war Britain, which is a historical approach to the study of public-market equity investors, focusing on the evolving role and behaviour of shareholders in the context of changing legal, political, economic, and social conditions. This research examines the shareholder in the post-war period and how the evolution of the shareholder body influenced corporate behaviour and the relationships amongst stakeholders, impacting the legal and political efforts to govern industry and financial markets. This work on the post-war shareholder addresses a number of themes, including: i) how the broader movements for democratisation influenced the treatment of shareholder interests and calls for stakeholder representation; ii) how the rhetoric of change created a narrative that deflected from the lack of systemic legal reforms and protected the status quo; iii) how, in the environment of the post-war consensus, attitudes towards equity ownership by the governing political parties deradicalised, which proved unsustainable with increasing industrial unrest and polarisation; and iv) how the institutionalisation of the shareholder body in the post-war period had profound effects on industry, the financial markets, and the economy. With these themes as a foundation, the evolutionary arch of the post-war shareholder body is examined, focusing on several key developments that influenced the treatment and perception of shareholder and stakeholder interests, including: i) nationalisations; ii) shareholder democracy; iii) corporate purpose and shareholder primacy; and iv) industrial democracy. This research also examines the post-1979 changes to shareholder and stakeholder interests, and in particular reforms to the Companies Act, and how these fit within the wider social, political, and economic contexts. Finally, the historical analysis of the shareholder in the post-war period provides a platform from which to consider contemporary questions on shareholder primacy and stakeholderism, corporate behaviour and purpose, and the demands for systemic legal reforms.
