This important volume begins with a major survey of the field by the editors, followed by seminal papers on the empirical and historical importance of joint production.The topic of joint production theory has played a central role in neo-classical criticism of classical theory, in Sraffa's proposed rehabilitation of classical theory, and in some Sraffa-based criticisms of Marxian theory. This prominence is not surprising for joint production (and the related use of fixed capital) are major empirical features of the modern economy. The volume brings together for the first time major works - many of which are not easily available - on joint production by a range of English, French, German and Italian authors.
