The paper presents conditions for non-parametric identification of a joint distribution when the marginal distributions are identified and the joint distribution is partially identified. Specifically, the paper considers the problem of estimating a J-dimensional Roy Model and shows that the...

The paper presents a theoretical and empirical analysis of learning in a prediction market. The paper presents necessary and sufficient conditions for prices to converge to the probability of an event as information is incorporated into the market. The theoretical results are augmented with...

Using bid data from 8,000 new and used Chevrolet Corvettes sold on eBay, this paper empirically tests Akerlof's (1970) hypothesis that the used car market is characterized by low quality and informational problems. The hypothesis states that the used market has a higher proportion of low quality...

This paper presents a model of moral hazard where differences in actions are driven by differences in time-preferences rather than differences in risk-preferences. The paper discusses two solutions to the time-preference induced incentive problem. First, in some circumstances, the incentive...

The paper presents sharp bounds on the identified set for classical factor models and non-parametric topic models based on results from the non-negative factorization literature. It compares the standard assumption (for factor models) of orthonormality of the factors (principal components...

The paper presents exclusion restrictions that allow identification of returns to schooling using data from the National Survey of Young Men (1966) (NLSYM66). The approach does not use instrumental variables (IV) or control function approaches. Instead, a non-parametric finite mixture model is...

Measurement error is a potential problem with estimating the wage effect associated with first-differences in twin's education levels. To account for this, Ashenfelter and Rouse (1998) provided two reports of each twin's education level. One is the own report and the second is the sibling's...

This paper estimates three duration models, one for each of the three clinical phases of drug development using publicly available data. Specifically, we estimate three discrete time mixed proportional hazard models, with some parameter constraints across models. We present the estimated...

The decision maker is assumed to observe a large number of experiments. The paper presents conditions for the existence of a unique prior over distributions that generate each of the observed samples. The axioms over experiments admit a recursive non-expected utility representation over...

This paper considers estimation of the treatment effect where the researcher has data from a large number of related experiments. The paper considers two cases. In the first, there are a large number of treated units. The paper shows that standard analogue estimate of higher moments of the...
