Knowledge that Transforms

A free-rider problem arises when a group choice between two alternatives has to be made on the basis of privately collected evidence, leading to insufficient effort in gathering evidence and an ex ante welfare loss for the group. To alleviate the free-rider problem, the group can commit to a "conservative" rule, whereby the decision is made against the alternative favored by the group's preference or prior when evidence supports it but is not preponderant. Optimal conservatism increases private incentives to gather evidence and improves the quality of the group decision. My result explains why sometimes groups appear overly cautious toward favored alternatives.

This paper presents a model in which a durable goods monopolist sells a product to two buyers. Each buyer is privately informed about his own valuation. Thus all players are imperfectly informed about market demand. We study the monopolist’s pricing behavior as players’ uncertainty regarding demand vanishes in the limit. In the limit, players are perfectly informed about the downward‐sloping demand. We show that in all games belonging to a fixed and open neighborhood of the limit game there exists a generically unique equilibrium outcome that exhibits Coasian dynamics and in which play lasts for at most two periods. A laboratory experiment shows that, consistent with our theory, outcomes in the Certain and Uncertain Demand treatments are the same. Median opening prices in both treatments are roughly at the level predicted and considerably below the monopoly price. Consistent with Coasian dynamics, these prices are lower for higher discount factors. Demand withholding, however, leads to more trading periods than predicted.

This paper is based on the idea that for each partner in a marriage, there are two distinct types of leisure. One type is each person’s independent (or private) leisure, and the other type is spousal leisure, whose importance has long been emphasized in the literature of psychology. While each type of leisure is unobservable (only total leisure is observed), it is shown that the recent collective models of the intrahousehold allocation initiated by Chiappori can be extended to identify each type of leisure up to an additive constant. In particular, the effects of each member’s wage, household unearned income, and extrahousehold environmental parameters on the independent and spousal leisure and on the sharing rule are fully identified. The observational requirement here is the same as in other studies, namely, the observation of individual labor supply, individual wages, household unearned income, one assignable good, and consumption expenditure at the household level.

An innovation in this paper is to introduce a time‐to‐build technology for the production of market capital into a model with home production. Our main finding is that the two anomalies that have plagued all household production models—the positive correlation between business and household investment, and household investment's leading business investment over the business cycle—are resolved when time to build is added.

Interpersonal preferencespreferences that depend on the characteristics of othersare typically hard to infer from observable individual behavior. As an alternative approach, this paper uses survey data to investigate interpersonal preferences. I show that self-reported attitudes toward welfare spending are determined not only by financial self-interest but also by interpersonal preferences. These interpersonal preferences are characterized by a negative exposure effectindividuals decrease their support for welfare as the welfare recipiency rate in their community risesand racial group loyaltyindividuals increase their support for welfare spending as the share of local recipients from their own racial group rises. These findings help to explain why levels of welfare benefits are relatively low in racially heterogeneous states.

This paper offers some new estimates of the contribution of learning to the rapid increases in labor productivity observed in the construction of Liberty ships during World War II. The study exploits new data on physical capital investment and vessel quality constructed from contemporary records held at the National Archives. Estimates of the rate of learning are shown to be sensitive to the inclusion of the new capital data, and data on vessel quality provide evidence that part of the measured productivity increases were secured at the expense of quality.

In this paper we show that fixed‐term contracts, which are commonly used to franchise highways, do not allocate demand risk optimally. We characterize the optimal risk‐sharing contract and show that it can be implemented with a fairly straightforward mechanism—a least‐present‐value‐of‐revenue auction. Instead of bidding on tolls (or franchise lengths), as in the case of fixed‐term franchises, in an LPVR auction the bidding variable is the present value of toll revenues. The lowest bid wins and the franchise ends when that amount has been collected. We also show that the welfare gains that can be attained by replacing fixed‐term auctions with LPVR auctions are substantial.
