Adapting to Crisis: Accounting Information Systems during the Weimar Hyperinflation

Published online by Cambridge University Press:  25 November 2020

Abstract

German corporations are characterized as having been adaptable in the face of numerous traumatizing events during the twentieth century. This article explores how firms adapted their accounting information systems during the hyperinflation of the 1920s. It suggests that responses to the crisis focused on system elements identified as key to continuing operations. Initially, firms amended selling and purchasing arrangements, modified financial reporting, and shifted managerial reporting to nonmonetary information. As inflation accelerated, human resources were diverted to maintaining critical functions, especially those related to remunerating labor. While some elements of accounting systems fell into disrepair, there were also examples of innovation.

14 See Fear and Kobrak, “Diverging Paths.” The focus on theory and financial reporting is evident in the work of historians of the German hyperinflation who touch on accounting-related themes. See, for example, Gerald D. Feldman, Carl-Ludwig Holtfrerich, Gerhard A. Ritter, and Peter-Christian Witt, eds, The German Inflation Reconsidered: A Preliminary Balance (New York, 1982); Carl-Ludwig Holtfrerich, The German Inflation 1914–1923: Causes and Effects in International Perspective (New York, 1986); Karsten Laursen and Jorgen Pedersen, The German Inflation, 1918–1923 (Amsterdam, 1964); Steven B.

Rowley, Hyperinflation in Germany: Perceptions of a Process (Aldershot, 1994); and Frederick Taylor, The Downfall of Money: Germany's Hyperinflation and the Destruction of the Middle Class (London, 2014). Economic historians also tend to dwell on financial reporting. See, for example, Constantino Bresciani-Turroni, The Economics of Inflation: A Study of Currency Depreciation in Post-War Germany (London, 1937), 220, 222, 261, 275–76; Frank D.

23 The most significant statutory intervention came in December 1923 (and is discussed later). A law passed in early 1923 concerned shielding firms from inflation-induced tax burdens. See Wilhelm Gerloff and Georg Strutz, Steuerwirtschaft und Steuerrecht im Zeichen der Geldentwertung (Berlin, 1923).

24 Note that liquidations, mergers, fires, floods, world war, and the partition of Germany have all resulted in the loss or destruction of numerous business records since the early 1920s. The records for our period held in the repositories we accessed were often highly fragmented.
