Abstract
This paper analyzes a novel data set on all corporate political donations made in a post-transition country, the Czech Republic, between 1995 and 2014. Using these donations as a proxy for political connections, I assess the relationship between being connected to a political party and the financial performance of the connected firms.
In line with the theoretical predictions, I find that firms successfully use political connections to gain advantage over their non-connected peers. The results show that connected firms perform significantly better in the years around the establishment of a connection, and that the effect is stronger for firms that work closely with the public sector.
Furthermore, I present evidence that firms that donations seem to represent actual measures of the level of connectedness, and firms that have contributed more outperform other connected firms. I then develop a dynamic approach to match connected firms with their non-connected but otherwise similar peers and conservatively estimate that being politically connected is associated with 20 to 30 % higher profitability than that of non-connected firms.
I also find that non-connected firms that receive public money perform similarly to connected firms, suggesting that other sources of connections, such as personal ties, have played a significant role during the post-transition period in the Czech Republic.
