Gibrat's law for countries

A reassessment of Gibrat's Law in the context of country size is carried out in this paper. In addition, how similarly population is distributed in cities and countries is analyzed from a temporal perspective. Although evidence of Gibrat's Law is found, it is weaker than that previously established in Rose (J Money Credit Bank 38(8):2225-2246, 2006). This is due to the methodology applied and is especially appreciable in very small countries. Nonetheless, we observe that the population growth process in countries is similar to that of cities. As a result, the similarities between how the population is distributed in these two geographical categories have increased over time.
