Recent work documents that better legal institutions are associated with broader equity markets. We investigate whether international differences in legal institutions also help explain the international cross-section of expected stock returns. We document three main regularities. First, total...

The regulations that shape the design and the operations of corporations, credit and securities markets differ vastly from country to country. In addition, similar regulations are often unequally enforced in different countries. Economists still have an imperfect understanding of why these...

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...

If the private benefits of control are high and management owns a small equity stake, managers and workers are natural allies. Two forces are at play. First, managers can transform employees into a 'poison pill' through generous long-term labour contracts and thereby reduce the firm’s...

Stricter laws require more incisive and costlier enforcement. Since 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...

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...

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...

The Paper analyses the political decision that determines the degree of investor protection. We show that entrepreneurs and workers can strike a political agreement by which low investor protection is exchanged for high employment protection. This ‘corporatist’ agreement is feasible if the...

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...
