Volatility and Economic Growth in the Twentieth Century


This paper analyses the international distribution of growth rates and its dynamics during the twentieth century. We show that the whole century is characterized by a high heterogeneity in the distribution of GDP per capita growth rates, which is reflected in different shapes and a persistent asymmetry of the distributions at the regional level and for countries of different development levels. In the context of the global conflicts that characterized the first half of the twentieth century and involved mainly large economies, the well-known negative scale relation between volatility and country size is not significant. After 1956, a redistribution of volatility leads to a significant negative scale-relation, considered as a robust feature of the evolution of economic organizations. Our results contribute with empirical evidence that call the attention to traditional macroeconomic theories to better explain the underlying complexity of the growth process and sheds light on its historical evolution.
