Pesch, a German Jesuit scholar and economist, wrote the longest, most exhaustive economics text ever written. The five-volume "Lehrbuch der National okonomie" examines all serious economic thinking up until Pesch's time. This work provides an English translation of the works of Pesch. This fifth volume covers the second and third stages in the economic process: exchange and income determination. It deals with money and the banking system, foreign exchange and entrepreneurial income. It concludes with what Persch designates as distortions in the economic process, economic crisis and the strike and lockout.
