Financial development and economic complexity: The role of country stability

Abstract The aim of this paper is to examine the relationships between financial development (FD), economic complexity and country stability. To achieve this objective, this paper applies a finite mixture model to a sample of 92 developing countries over the period 1995–2018. The study posits that the effect of FD on economic complexity differs across groups of countries with similar but unobserved characteristics. The study finds that the effect of FD on economic complexity varies across four classes of countries, which differ according to their level of economic, political and financial stability. Furthermore, the study argues that stable countries are more likely to be in class 1, including more performing countries – that is, the group of countries where FD spurs economic complexity. This finding remains consistent even when alternative measures of FD and economic complexity are considered. Hence, efforts by developing countries to undertake sound reforms to reduce economic, political and financial risks could help leverage the benefits of FD in fostering the development of sophisticated and complex economies.
