(2024). Generative AI and Firm-level Productivity: Evidence from Startup Funding Dynamics. DOI
- New general-purpose technologies have the potential to fundamentally change the dynamics of entrepreneurial firms. This paper provides new evidence on the impact of Generative AI on startup productivity: We argue that valuable but non-exclusive technological innovations can be a source of competitive advantage if entrepreneurs leverage them as complementary assets to their existing skill set. To show this, we exploit the release of GitHub Copilot as a quasi-natural experiment affecting software-developing startups. We find a significant reduction in the time-to-initial-funding, an early-stage productivity indicator, by about 20% relative to comparable startups. These effects are strongest for startups whose founders have more technological or managerial experience. Our analysis highlights the considerable implications of GenAI as a new resource available to decision-makers, shaping startup dynamics and productivity.
(2023). Intellectual Property as Loan Collateral. DOI
- This study provides a first comprehensive picture of the use of intellectual property (IP) as loan collateral, its determinants, and its effect on firm trajectories. Using novel administrative data, we exploit the French institutional setting and show that firms from diverse industries use selected trademarks (72%), patents (26%), and designs (2%) to secure loans. We find that IP pledges have large positive effects on debt financing, in particular for small, financially constrained firms. The results are robust to exogenous variation in the pledgeability of alternative collateral. Further, using IP as loan collateral is associated with sizable increases in firm-level growth.
(2022). Leveraging Intellectual Property: The Value of Harmonized Enforcement Regimes.
- We provide new evidence on how intellectual property (IP) rights support external debt financing by investigating exogenous variation in patent right enforcement. Deploying a unique, large-scale sample of European firms, we exploit the 2004 EU Enforcement Directive, a major legislative change strengthening IP rights across Europe, as identifying event. Results show that firms with valuable patent portfolios disproportionally increase debt financing by about 21%. Effects are particularly pronounced for private SMEs, ex-ante financially constrained firms, and in competitive environments. Adding previously undisclosed patent collateral information provides suggestive evidence that enhanced IP enforcement benefits debt financing beyond a mere collateral channel.

(2022). Intellectual Property as Business Loan Collateral: A Taxonomy on Institutional and Economic Determinants. DOI
- Using intellectual property rights (IPR) as collateral to secure debt financing can form a promising strategy, in particular for small, financially constrained firms. Despite an ongoing shift to a more technology-based economy, the collateralizing of IPR is still trailing behind the use of traditional asset classes. In this paper, we develop a new taxonomy on the key determinants of using IPR as collateral. The taxonomy defines two pillars that govern the use of IPR collateral that distinguish between institutional and economic factors. The institutional pillar covers contract law, IPR registries, and banking regulation. We apply the taxonomy to the current legal and economic states in several industrialized economies to identify potential impediments to IPR-backed debt financing. The economic pillar constitutes the influence of IPR characteristics on the trade-off between the economic costs and benefits of collateralizing IPR. We propose that IPR collateral can have significant advantages regarding signaling, agency issues, and the creation of pledgable income. Based on these considerations we derive several testable hypotheses on the circumstances under which IPR collateral might be particularly well-suited to attract debt financing. Taken together, our taxonomy can be viewed as the foundation for future research on IPR as loan collateral for businesses.
(2019). Leverage Intellectual Property: The Value of Harmonized Enforcement Regimes, Proceedings of Paris December 2019 Finance Meeting EUROFIDAI - ESSEC 2019.
- This paper analyses the importance of intellectual property in determining capital structure decisions. We argue that firms can use their patent stock as collateral and thereby relax possible debt financing restrictions. Using data from the European Patent Office and balance sheet data of European companies, we find that larger and more valuable patent stocks lead to higher debt-ratios - controlling for well-established capital structure determinants. We further assess variation across as well as within industries and show that effects are mainly driven by tech-oriented and research intensive firms. Drawing on a legislative change in EU- law, allows us to establish a causal relationship between firms' patent portfolio and their use of debt. Results provide a new perspective on optimal capital structure decisions. From a policy perspective, our findings suggest to further harmonize enforcement rules on intellectual property to support financially constrained, innovative firms.
