This study seeks to understand how the economic paradigm shift observed at the end of the Late Antiquity reshaped local economies. During the second half of the sixth century the region of the southern Balkans underwent many economic changes followed by a prolonged recession. This recession played a major role in the transformation of the urban centers, a process which differed by region. The main aim of this study is to identify the local variation of large-scale changes and to examine their long-term consequences at a micro-level, taking into consideration several variables, such as artisanal activity, specialization and coin circulation. The numismatic datasets of the FLAME project will provide the main framework for the analysis of the evolution of the local economies.
