The Life Cycle Effects of Corporate Takeover Defenses

We document that the relation between firm value and the use of takeover defenses is positive for young firms but becomes negative as firms age. This value reversal pattern reflects specific changes in the costs and benefits of takeover defenses as firms age and arises because defenses are sticky and rarely removed. Firms can attenuate the value reversal by removing defenses, but do so only when the defenses become very costly and adjustment costs are low. The value reversal explains previous mixed evidence about takeover defenses and implies that firm age proxies for takeover defenses’ heterogeneous impacts on firm value.

Exchange Competition, Entry, and Welfare

We assess the consequences for market quality and welfare of different entry regimes and exchange pricing policies. To do so, we integrate a microstructure model with a free-entry, exchange competition model where exchanges have market power in technological services. Free-entry delivers superior liquidity and welfare outcomes vis-`a-vis an unregulated monopoly, but entry can be excessive or insufficient. Depending on the extent of the monopolist's technological services undersupply compared to the first best, a planner can achieve a higher welfare controlling entry or platform fees.

Do Investment-Based Models Explain Equity Returns? Evidence from Euler Equations

We investigate the empirical implications of the investment-based model of asset pricing for the Hansen-Jagannathan and Kozak-Nagel-Santosh discount factors in the linear span of equity returns. We find that the stochastic discount factors satisfying the Euler equation for equity returns cannot satisfy the Euler equation for investment returns because returns on corporate investment covary inversely with the sources of equity risk relative to returns on equity. As a result, the model fails to replicate the level of the risk premium. Our results suggest that joint restrictions on the optimality of investment and consumption pose stringent conditions for candidate production models.

Does Career Risk Deter Potential Entrepreneurs?

Do potential entrepreneurs remain in wage employment because of concerns that they will face worse job opportunities should their entrepreneurial ventures fail? Using a Canadian reform that extends job-protected leave to one year for women giving birth after a cutoff date, we study whether the option to return to a previous job increases entrepreneurship. A regression discontinuity design reveals that a longer job-protected leave increases entrepreneurship by 1.9 percentage points. These entrepreneurs start incorporated businesses that hire employees, in industries in which experimentation before entry has low costs and high benefits.

Trust and Insurance Contracts

We assemble homeowner insurance claims from 28 independently operated country subsidiaries of a multinational insurance firm. We propose a new insurance model, in which consumers can make invalid claims and firms can deny valid claims, as is common in the data. In the model, trust and honesty shape equilibrium insurance contracts, disputes, and claim payments, especially when disputes are too small for courts. We test the model by investigating claim incidence, dispute, rejection, and payment, as well as insurance costs and pricing across countries. The evidence is consistent with the centrality of trust for insurance markets, as our model predicts.
