What role did the agricultural sector play in the economic crash of 1929? Taking evidence from country cases across Europe and the Americas, this edited volume explores short-, medium- and long- term perspectives on the primary sector. The monograph brings together the voices of an international panel of contributors who examine issues such as falling prices, industrial production, unemployment and the stagnation of aggregate demand. Together, they frame the interwar period as a pivotal turning point in the decline of subsistence agriculture and the growth of agricultural subsidies, which remain a key policy tool in many economies today. This illuminating book will be of interest to advanced students and researchers in economic history, agricultural history, globalization and economic development.
