Two recent failures of the United States intelligence system have led to the creation of high-level investigative commissions. The failure to prevent the terrorist attacks of 9/11 prompted the creation of the 9/11 Commission, and the mistaken belief that Saddam Hussein had retained weapons of...

Understanding the impact of legal protection on investment is of major importance. This paper provides a framework for addressing this issue, and shows that investment may actually be higher in the absence of legal protection. Focusing on the application to innovation, in an environment where an...

This paper develops the building blocks for a legal theory of finance. LTF holds that financial markets are legally constructed and as such occupy an essentially hybrid place between state and market, public and private. At the same time, financial markets exhibit dynamics that frequently put...

We document that trust in public institutions--and particularly trust in banks, business and government--has declined over recent years. U.S. time series evidence suggests that this partly reflects the pro-cyclical nature of trust in institutions. Cross-country comparisons reveal a clear legacy...

We show that task juggling, i.e., the spreading of effort across too many active projects, decreases the performance of workers, raising the chances of low throughput, long duration of projects and exploding backlogs. Individual speed of job completion cannot be explained only in terms of...

In the 'Knightian' theory of entrepreneurship, entrepreneurs provide insurance to workers by paying fixed wages and bear all the risk of production. This paper endogenizes entrepreneurial risk by allowing for optimal insurance contracts as well as the occupational self-selection. Moral hazard...

Interest in prediction markets has increased in the last decade, driven in part by the hope that these markets will prove to be valuable tools in forecasting, decision-making and risk management - in both the public and private sectors. This paper outlines five open questions in the literature,...

We develop a model of the gambler's fallacy -- the mistaken belief that random sequences should exhibit systematic reversals. We show that an individual who holds this belief and observes a sequence of signals can exaggerate the magnitude of changes in an underlying state but underestimate their...

We propose a rational theory of momentum and reversal based on delegated portfolio management. A competitive investor can invest through an index fund or an active fund run by a manager with unknown ability. Following a negative cashflow shock to assets held by the active fund, the investor...

We propose a model in which assets with identical cash flows can trade at different prices. Infinitely-lived agents can establish long positions in a search spot market, or short positions by first borrowing an asset in a search repo market. We show that short-sellers can endogenously...
