We study a model where some investors ("hedgers") are bad at information processing, while others ("speculators") have superior information-processing ability and trade purely to exploit it. The disclosure of financial information induces a trade externality: if speculators refrain from trading,...

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...

We analyze corporate fraud in a model in which managers have superior information but are biased against liquidation, because of their private benefits from empire building. This may induce them to misreport information and even bribe auditors when liquidation would be value-increasing. To curb...

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...

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...

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...

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...

Has economic research been helpful in dealing with the financial crises of the early 2000s? On the whole, the answer is negative, although there are bright spots. Economists have largely failed to predict both crises, largely because most of them were not analytically equipped to understand...
