The Two-Tier Board System and Underpricing of Initial Public Offerings : Evidence from Austria

We study the relation between initial IPO underpricing and two-tier board structure in the Vienna Stock Exchange of Austria, where a two-tier board is mandatory for listed companies. The board ratio, defined as the size of the supervisory board to the management board, is used to capture the effect of two-tiered board on underpricing. The results show that the board ratio is negatively related with underpricing, consistent with the agency theory which predicts that more effective monitoring implied in a relatively larger supervisory board will lead to lower agency costs, and thus lower underpricing. The results are robust to the inclusion of control variables and suggest that firms seeking to raise external capital will be helped by adopting strong corporate governance standards
