In 20 new and previously published essays Schefold (economics, Goethe U., Franfurt am Main) confronts a number of controversies that have arisen with the revival of classical economic theory since the 1960s. Concerned more with explaining than criticizing classical economics, he discusses Sraffa's theory; general properties of single and joint production systems; the dominant technique, fixed capital and technical progress; the composition of output; and relations between classic, neoclassical, and Keynesian theories.
