This paper examines the quality of credit ratings assigned to banks in Europe and the United States by the three largest rating agencies over the past two decades. We interpret credit ratings as relative assessments of creditworthiness, and define a new ordinal metric of rating error based on...

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...

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...

Theory predicts that information sharing among lenders attenuates adverse selection and moral hazard, and can therefore increase lending and reduce default rates. To test these predictions, we construct a new international data set on private credit bureaus and public credit registers. We find...

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...

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...

In choosing transparency, firms must trade off the benefits from better access to finance against the cost of a greater tax burden. We study this trade-off in a model with distortionary taxes and endogenous rationing of external finance. The evidence from two different data sets, one formed only...

We present a model of labor market equilibrium in which managers are risk-averse, managerial talent (‘alpha’) is scarce, and firms seek alpha, that is, compete for this talent. When managers are not mobile across firms, firms provide efficient long-term compensation, which allows for...

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...

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...
