Increased debt and industry product markets an empirical analysis

Journal of Financial Economics 1995 37(2), 189-238
This paper tests for changes in firms' production and pricing decisions in four industries in which firms have sharply increased their financial leverage. The analysis of product price and quantity data shows that industry product market decisions are associated with capital structure. In three industries, output is negatively associated with the average industry debt ratio. In the one industry which shows a positive association between output and debt ratios, rival firms have low financial leverage and entry barriers are relatively low. Analysis of executive compensation data supports the hypothesis that managers' incentives to maximize shareholders' wealth increase following recapitalization.

The impact of consumer credit access on self-employment and entrepreneurship

Journal of Financial Economics 2021 141(1), 345-371
We examine how consumer credit affects entrepreneurship by linking three million earnings and pass-through tax records to credit reports. In the cross-section, we show that self-employment without employees and employer firm ownership increase monotonically with credit limits and credit scores. We then isolate individuals who have had discrete increases in credit limits after the exogenous removal of bankruptcy flags to measure the effects of personal credit on entrepreneurship. Following bankruptcy flag removal, individuals are more likely to start a new employer business and borrow extensively. Those who own businesses with employees borrow $40,000 more after bankruptcy flag removal, a 33% gain relative to the sample average.

Intellectual property protection lost and competition: An examination using large language models

Journal of Financial Economics 2026 182, 104306 open access
We examine the impact of lost intellectual property protection on innovation, competition, firm performance, and valuation. We consider firms whose ability to protect intellectual property (IP) using patents is weakened following a major Supreme Court decision. We use large language models (LLM) to identify firms’ patent portfolios’ exposure to this decision and find an unequal impact. Large firms gain and small firms lose. Large impacted firms benefit as their sales growth increases and their exposure to lawsuits decreases. Small impacted firms lose as they face increased competition, product-market encroachment, and lower profits and valuations. They increase R&D and nondisclosure agreements.
