Using data for 939 publicly listed firms from 17 European countries over the period from 2004 to 2013, we investigate the effect of used credit lines on R&D investments, controlling for other determinants of R&D investments, i.e., cash flows, cash holdings, sales growth, equity financing, and Tobin's Q. Our estimation results, based on the system-GMM method, show that used credit lines have a positive and significant impact on R&D investments. In addition, we find that this impact is more pronounced for small and young firms than for large and mature firms. These results show that firms use credit lines as part of their liquidity management tools for supporting their R&D investments. Finally, we provide evidence that European firms in bank-based countries increased their use of credit lines for financing their R&D investments during the financial crisis of 2007–2009, while the link between R&D investments and used credit lines became weaker during the European sovereign debt crisis of 2010–2013.

The paper investigates how firms operating in capital market-oriented economies (the U.K. and the U.S.) and bank-oriented economies (France, Germany, and Japan) determine their capital structure. Using panel data and a two-step system-GMM procedure, the paper finds that the leverage ratio is positively affected by the tangibility of assets and the size of the firm, but declines with an increase in firm profitability, growth opportunities, and share price performance in both types of economies. The leverage ratio is also affected by the market conditions in which the firm operates. The degree and effectiveness of these determinants are dependent on the country's legal and financial traditions. The results also confirm that firms have target leverage ratioswith French firms being the fastest in adjusting their capital structure toward their target level and Japanese firms the slowest. Overall, the capital structure of a firm is heavily influenced by the economic environment and its institutions, corporate governance practices, tax systems, the borrower-lender relation, exposure to capital markets, and the level of investor protection in the country in which the firm operates.
