Using the adoption of Zombie Property Laws (ZL) across several US states, we show that requiring lenders to maintain properties in the foreclosure process affects mortgage lending decisions and standards. Difference-in-differences estimations using a state border design show that ZL incentivizes lenders to screen mortgage applications more carefully: they deny more applications and impose higher interest rates on originated loans, especially risky loans. In turn, these loans exhibit higher ex post performance. ZL also affects lender behavior after borrowers become distressed, causing them to strategically keep delinquent mortgages alive. Our findings inform the debate on policy responses to foreclosure crises.

Theory offers conflicting predictions on how bank specialization affects corporate innovation. We show that the sign and magnitude of this effect vary with the degree of “asset overhang” across sectors—the risk that new technologies reduce the value of banks’ legacy loan portfolios. Using Belgian innovation survey data and US patent data, we find that lenders’ sectoral specialization enhances innovation for firms operating in sectors with low asset overhang, but hinders innovation in sectors with high asset overhang. These findings are robust to different measures of asset overhang and an identification strategy using bank mergers. We further show that these heterogeneous effects arise through financial contracting. Our findings highlight how product market characteristics shape the role of bank specialization in innovation.

Cyber risk exposes banks to operational disruptions that can trigger runs. A bank chooses its cybersecurity by trading off protection against attacks with remaining resilient if an attack succeeds. Cybersecurity functions as a risk-management decision: it reduces the bank’s exposure to adverse outcomes but entails lower balance-sheet returns. Equilibrium cybersecurity depends on whether failure is driven by insolvency or illiquidity. When failure is insolvency-driven, bank and creditor actions reinforce one another: greater cybersecurity leads to a higher debt burden, which strengthens incentives for protection. When failure is illiquidity-driven, additional cybersecurity lowers the debt burden, eliminating the bank’s private risk–return trade-off. Socially optimal cybersecurity differs from the private choice, and corrective instruments must target either the protection or resilience margins. We extend the model to a system-wide environment in which cybersecurity is a public good, highlighting free-riding and the need for targeted regulation.

I analyze the effect of non-compete agreements (NCAs) on the allocation of inventors across product markets. NCAs constrain the within-industry employment choice set of inventors. In a staggered difference-in-differences, I show causal effects that two in hundred inventors per year (increase of 42 percent) respond to more enforceable NCAs by moving to more distant product markets. Across-industry mobility is largest for inventors likely bound by NCAs. Within-industry mobility on the other hand is reduced. Reallocated inventors are subsequently less productive and there is a lower quality match between inventors and their new employers. I highlight how product market choice set constraints can have detrimental effects through reallocation of human capital to more distant product markets.

We study the effects of state-level Paid Family Leave (PFL) laws on US firms across a broad panel of private and public companies. Following PFL adoption, female employee turnover declines, labor productivity increases, and treated firms experience significant improvements in operating performance. These effects are stronger in regions with a larger supply of childbearing-age female labor, among R&D-intensive firms and firms with high intangible capital, consistent with a mechanism in which PFL reduces job separation expectations and encourages investment in firm-specific human capital. Our findings suggest that PFL can generate tangible firm-level benefits by enhancing workforce stability and productivity.

Privately informed about firm fundamentals, corporate insiders detect activism-motivated trades better than other traders. This article solves the model of this novel form of insider trading motivated by noninsider information and presents empirical evidence. Corporate insiders preserve their ownership (restraining from selling or buying more) before activist interventions go public to benefit from price appreciation and to defend their private benefits of control. Surveillance technology facilitates response to predisclosure activist trading, especially when positive information about firm fundamentals is absent, supporting the mechanism that insiders attribute order flows to activist interest when speculation on fundamentals can be ruled out.

The tax rate on capital gains of equity has varied substantially over time and correlates negatively with realized capital gains and tax revenue. In our model, investors who anticipate the dynamics of the tax rate in their bond–equity mix realize greater gains when realized equity returns are higher, the capital gains tax rate is lower, and capital losses carried forward are larger. Simulating a calibrated population of investors produces model data consistent with tax revenue from capital gains realizations. Our model can inform the policymaker’s choice of the capital gains tax rate.

This article explores the relationship between a firm’s legal contracting environment and its innovation incentives. Using granular data from the pharmaceutical industry, we examine a contracting mechanism through which incumbents maintain market power: “pay-for-delay” agreements to delay the market entry of competitors. Exploiting a shock where such contracts become legally tenuous, we find that affected incumbents subsequently increase their innovation activity across a variety of project-level measures. Exploring the nature of this innovation, we also find that it is more “impactful” from a scientific and commercial standpoint. The results provide novel evidence that restricting the contracting space can boost innovation at the firm level. However, at the extensive margin we find a reduction in innovation by new entrants in response to increased competition, suggesting a nuanced effect on aggregate innovation.

The idea of separating retail and investment banking remains controversial. Exploiting the introduction of UK ring-fencing requirements, we show that this separation has a range of previously undocumented side effects for credit supply, competition, and risk-taking in credit markets not directly targeted by the reform. By redirecting the benefits of deposit funding toward retail activities, ring-fencing incentivises universal banks to expand mortgage lending. This rebalancing reduces the cost of household credit, without eroding lending standards. But it also increases mortgage market concentration, pushes smaller banks toward riskier lending, and is mirrored by a reduction in syndicated loans and credit lines.
