The GrEco Project aims to promote academic research on Lord William Wyndham Grenville’s economic thought. Since most of his economic writings remained unpublished at the outset of the project, its first task is to locate, date, transcribe, and publish Grenville’s economic works and correspondence. Initially, this material will be made available online through the GrEco Project website. A major objective of the project, however, is to produce a scholarly printed edition of Grenville’s economic writings. The corpus assembled and made available to researchers is intended to support a regular seminar in which scholars associated with the project may discuss their research and exchange ideas. Grenville’s role in the institutionalization of political economy, both in the British Parliament and at Oxford University, the extensive exchanges he maintained with the leading economists of his time, and the wide range of issues addressed in his writings should attract a broad community of scholars. Without claiming to be exhaustive, these issues include theories of value, population, wages, capital accumulation, international trade, the corn Laws, the poor Laws, the convertibility of currency, the financing of the public debt, the slave trade, the method of political economy, the relationships between economics and politics and between economics and religion, the training of civil servants employed by the British East India Company, and the emergence of political economy as an academic discipline.
