Peter Groenewegen's reputation as a Chronicler of the history of economics is unparalleled. Building on his respected collection on eighteenth century economics, this new book focuses on the nineteenth and early twentieth centuries, reprinting essays on classical and modern economics. Several essays have never been previously published while many are difficult to access having been written across the 1970s, 1980s and 1990s. This is an invaluable resource for historians, students and academics involved in the history of economics.
