This paper is an exercise in comparative institutional analysis, asking what kinds of arrangements most facilitate innovation. After identifying pervasive market failures in innovation, it explains why those associated with the Nordic model may be particularly conducive to innovation, and...

This paper attempts to provide a more complete reckoning of the costs of the Iraq War, using standard economic and accounting/ budgetary frameworks. As of December 30, 2005, total spending for combat and support operations in Iraq is $251bn, and the CBO's estimates put the projected total direct...

We present a model of shadow banking in which financial intermediaries originate and trade loans, assemble these loans into diversified portfolios, and then finance these portfolios externally with riskless debt. In this model: i) outside investor wealth drives the demand for riskless debt and...

We present a new model of money management, in which investors delegate portfolio management to professionals based not only on performance, but also on trust. Trust in the manager reduces an investor's perception of the riskiness of a given investment, and allows managers to charge higher fees...

In an earlier paper, we showed that integrated individual accounts, allowing individuals to borrow against future pensions when they are unemployed, can be welfare increasing, because it allows increased inter-temporal consumption smoothing without attenuating incentives to search. Here, we...

We present a model of judicial decision making in which the judge overweights the salient facts of the case. The context of the judicial decision, which is comparative by nature, shapes which aspects of the case stand out and draw the judge's attention. By focusing judicial attention on such...

We present a theory of choice among lotteries in which the decision maker's attention is drawn to (precisely defined) salient payoffs. This leads the decision maker to a context-dependent representation of lotteries in which true probabilities are replaced by decision weights distorted in favor...

We propose a theory of financial intermediaries operating in markets influenced by investor sentiment. In our model, banks make loans, securitize these loans, trade in them, or hold cash. They can also borrow money, using their security holdings as collateral. We embed such banks in a stylized...

Analyses of the role of rational speculators in financial markets usually presume that such investors dampen price fluctuations by trading against liquidity or noise traders. This conclusion does not necessarily hold when noise traders follow positive-feedback investment strategies buy when...

The Coase theorem implies that, in a world of positive transaction costs, any of a number of strategies, including judicially enforced private contracts, judicially enforced laws, or even government regulation, may be the cheapest way to bring about efficient resource allocation. Unfortunately,...
