Informal or Formal Financing? Evidence on the Co-Funding of Chinese Firms

Hans Degryse Liping Lu Steven Ongena

in: Journal of Financial Intermediation , 2016


Different modes of external finance provide heterogeneous benefits for the borrowing firms. Informal finance offers informational advantages whereas formal finance is scalable. Using unique survey data from China, we find that informal finance is associated with higher sales growth for small firms but lower sales growth for large firms. We identify a complementary effect between informal and formal finance for the sales growth of small firms, but not for large firms. Co-funding, thereby simultaneously using the informational advantage of informal finance and the scalability of formal finance, is therefore the optimal choice for small firms.

Legal Insider Trading and Stock Market Liquidity

Hans Degryse Frank de Jong Jérémie Lefebvre

in: De Economist , Nr. 1, 2016


This paper assesses the impact of legal trades by corporate insiders on the liquidity of the firm’s stock. For this purpose, we analyze two liquidity measures and one information asymmetry measure. The analysis allows us to study as well the effect of a change in insider trading regulation, namely the implementation of the Market Abuse Directive (European Union Directive 2003/6/EC) on the Dutch stock market. The first set of results shows that, in accordance with theories of asymmetric information, the intensity of legal insider trading in a given company is positively related to the bid-ask spread and to the information asymmetry measure. We also find that the Market Abuse Directive did not reduce significantly this effect. Secondly, analyzing liquidity and information asymmetry around the days of legal insider trading, we find that small and large capitalization stocks see their bid-ask spread and the permanent price impact increase when insiders trade. For mid-cap stocks, only the permanent price impact increases. Finally, we could not detect a significant improvement of these results following the change in regulation.

On the Nonexclusivity of Loan Contracts: An Empirical Investigation

Hans Degryse Vasso Ioannidou Erik von Schedvin

in: Management Science , Nr. 12, 2016


We study how a bank's willingness to lend to a previously exclusive firm changes once the firm obtains a loan from another bank ("outside loan") and breaks an exclusive relationship. Using a difference-in-difference analysis and a setting where outside loans are observable, we document that an outside loan triggers a decrease in the initial bank's willingness to lend to the firm, i.e., outside loans are strategic substitutes. Consistent with concerns about coordination problems and higher indebtedness, we find that this reaction is more pronounced the larger the outside loan and it is muted if the initial bank's existing and future loans retain seniority and are protected with valuable collateral. Our results give a benevolent role to transparency enabling banks to mitigate adverse effects from outside loans. The resulting substitute behavior may also act as a stabilizing force in credit markets limiting positive comovements between lenders, decreasing the possibility of credit freezes and financial crises.
