Creditors often share information about their customers' credit record. Besides helping them to spot bad risks, this informational exchange acts as a disciplinary device. If creditors are known to exchange data about defaults, borrowers must consider that default on a current lender would...

Hierarchical clustering is a common procedure for identifying structure in a dataset, and this is frequently used for organizing genomic data. Although more advanced clustering algorithms are available, the simplicity and visual appeal of hierarchical clustering have made it ubiquitous in gene...

If management has high private benefits and a small equity stake, managers and workers are natural allies against takeover threats. 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...

Many economists argue that the primary economic function of banks is to provide cheap credit, and to facilitate this function, they advocate the strict protection and enforcement of creditor rights. But banks can serve another important economic function: through project screening they can...

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. We construct a new international data set on credit bureaus and public credit registers. The theoretical predictions are broadly...

In most of the postwar period Italy featured an abnormally high saving rate in comparison to that of most other industrialized countries. But this is no longer true. Under any definition, in the last decade the Italian saving rate has fallen below the average of the developed economies. Why was...
