“…We define a country's degree of financial development as the (standardized) ratio between total banking credit and real GDP, calculated as a country-level average between 1975 and 1990. In predetermining this variable, we seek to avoid the potential confounding effect of current economic condition and smooth out time variation in the size of banking credit due for example to booms or busts in the financial system (see, e.g., Rajan and Zingales (1998); Pagano and Pica (2012); Montone and Zwinkels (2020)). The choice of a banking measure over a stock market measure of financial development reflects the fact that the firms in our sample largely depend on debt to carry out their investments.…”
