We analyze how the law and its enforcement affect equity market equilibrium. Improvements in the legal system, while invariably associated with broader equity markets, have different effects on equity returns depending on the institutional change considered and on the degree of international...

This paper presents a political economy model where there is mutual feedback between investor protection and stock market development. Better investor protection induces companies to issue more equity and thereby leads to a broader stock market. In turn, equity issuance expands the shareholder...

Stricter laws require more incisive and costlier enforcement. Because enforcement activity depends both on available tax revenue and the honesty of officials, the optimal legal standard of a benevolent government is increasing in per capita income and decreasing in officials' corruption. In...

If management has high private benefits and owns a small equity stake, managers and workers are natural allies against a takeover threat. Two forces are at play. First, managers can transform employees into a "shark repellent" through long-term labor contracts and thereby reduce the firm's...

When firms' research can lead to potentially harmful innovations, public intervention may thwart their incentives to undertake research by reducing its expected profitability (average deterrence) and may guide the use of innovation (marginal deterrence). We compare four policy regimes: laissez...

We analyze optimal policy design when firms' research activity may lead to socially harmful innovations. Public intervention, affecting the expected profitability of innovation, may both thwart the incentives to undertake research (average deterrence) and guide the use to which innovation is put...

When a customer can borrow from several competing banks, multiple lending raises default risk. If creditor rights are poorly protected, this contractual externality can generate novel equilibria with strategic default and rationing, in addition to equilibria with excessive lending or...
