To understand how a stock market listing influences corporate policies if external financing is restricted, we examine how European public and counterfactual private firms jointly adjust their investment, financing, payout policies during the global financial crisis---when bank lending tightened. Our findings suggest that a stock market listing provides better access to external debt financing during the crisis as public firms, on average, net issue more long-term debt. Excess debt financing is, however, not allocated to investments but mostly to payouts to shareholders. 
Thus, a stock market listing relaxes financial constraints but induces managers to cater to shareholders during the crisis. Independent of a country's financial market structure (bank-based vs. market based) in our European firm sample, a stock market listing always provides a firm with more long-term debt during the crisis. In bank-based economies, this excess debt is mostly allocated to maintain investments while in market-based economies, inducing higher short-termist pressures, a stock-listing leads to lower investments and excess debt is used to maintain payouts.
  1. Managerial Optimism and the Perception of Financial Constraints, with Tobias Heizer (LMU Munich), September 2015.

    • Keywords: Managerial optimism, perceived financing constraints, distinguishing behavioral and rational predictions, matched survey and financial statement data.
We find that optimistic managers are more likely to perceive financing constraints, which is a fundamental but previously untested prediction of behavioral corporate finance theory. However, this effect is statistically significant but relatively small compared to other previously identified determinants of perceived financing constraints. Moreover, the vast majority of optimistic managers actually do not perceive any financing constraints. Our findings have implications for both behavioral corporate finance and financial constraints research. We argue that previous findings relating optimism and corporate policies are probably driven by perceived financing constraints and not optimism. Apart from their potential usefulness, commonly applied financial constraint indices are likely to be biased by not accounting for managerial optimism. Our analysis is based on large survey panel data for high-level managers of 2,897 German firms for the period 1995 to 2010, which is matched with financial and non-financial firm-level information. The data enable us to implement a survey based measure of managerial optimism and to directly access the managers’ perception of financing constraints from survey answers.
