Public banking and economic growth: The experiences of 10 countries since the 1950s until 2017

Despite the limited number of empirical works assessing the implications of public banks for economic growth, a wave of these institutions has arisen since 2000. With this in mind, this paper investigates the linkage between these banks and long-run growth in 10 countries. We find discouraging evidence on the role of these institutions in the growth process as public banks contributed to long-run economic growth in only two countries. More precisely, the public bank raised the gross domestic product in the Dominican Republic and investment in Singapore. In the remaining eight countries, long-run growth was harmed, or we did not find a long-run nexus running from the public bank. This is particularly surprising because some public banks in our sample have a long history of proper management and were given an important role in their country's development. We find long-run reverse causality in five countries, and, in all of them but in one, a larger gross domestic product per capita expanded public banks’ assets. Therefore, public banks were following the economic cycle. Considering all this, governments that aim to accelerate economic growth should be more cautious about the creation or promotion of these entities.
