In the past two decades, academic research has produced massive evidence of the beneficial role of financial development for growth and the allocation of investment. Our current vision, however, is dominated by instances of dysfunctional behavior of financial markets associated with acute and...

We investigate the determinants of firms’ implicit employment and wage insurance to employees against industry-level and idiosyncratic shocks. We rely on differences between family and nonfamily firms to identify the supply of insurance, and between national public insurance programs to gauge...

Speculators often advertise arbitrage opportunities in order to persuade other investors and thus accelerate the correction of mispricing. This induces under-diversification: a risk-averse arbitrageur will optimally advertise only one of several mispriced assets, and overweigh it in his...

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 fi…nancial information induces a trade externality; if speculators refrain from trading,...

We analyze corporate fraud in a setting 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...

We present a model in which issuers of asset backed securities choose to release coarse information to enhance the liquidity of their primary market, at the cost of reducing secondary market liquidity or even causing it to freeze. The degree of transparency is inefficiently low if the social...

Entrepreneurs may be legally bound to bequeath a minimal stake to non-controlling heirs. The size of this stake can reduce investment in family firms, by reducing the future income they can pledge to external financiers. Using a purpose-built indicator of the permissiveness of inheritance law...

This paper examines the role of credit rating agencies in the subprime crisis that triggered the 2007-08 financial turmoil. The focus of the paper is on two aspects of ratings that contributed to the boom and bust of the market for asset-backed securities:rating inflation and coarse information...

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...
