This paper analyzes the effects of mergers between firms competing by simultaneously
choosing price and location. Products combined by a merger are repositioned away from
each other to reduce cannibalization, and non-merging substitutes are, in response, ...

Abstract: We study mergers among firms that compete by simultaneously choosing price and
location. The merged firm moves its two products away from each other to reduce
cannibalization, and the non-merging firms move their products in between the merging ...

Abstract We show how to nonparametrically identify and estimate the distribution of random
coefficients that characterizes the heterogeneity among agents in a general class of
economic choice models. We introduce an axiom that we term separability and prove that ...

Abstract We show how to nonparametrically identify the distribution of heterogeneity in a
general class of structural economic choice models. We state an economic property known
as reducibility and prove that reducibility ensures identification. Reducibility makes ...

As first pointed out by Marschak and Andrews [1944], using the inputs and outputs of profit
maximizing firms to estimate production functions gives rise to an endogeneity problem. The
endogeneity problem is caused by the presence of productive factors that are ...

When studying consumption choices, econo mists have often relied on the abstraction of a
representative agent. Such an agent can indeed be shown to exist and to replicate the aggre
gate consumers' demand, but only under very strong (and actually quite unrealistic) ...

Abstract Empirical studies have cast doubt on one of the bedrocks of applied economic
modeling-the expected utility hypothesis. Economists have documented pricing anomalies,
like the long-shot bias in prediction markets (low probability events are priced too high), ...
We consider the invertibility of a nonparametric nonseparable demand system. Invertibility of
demand is important in several contexts, including identification of demand, estimation of
demand, testing of revealed preference, and economic theory requiring uniqueness of ...

Abstract In selection, each potential outcome is observed only for those who make a
particular discrete choice. In the generalized Roy model, we identify the joint distribution of
the outcomes by exploiting the relationship between the potential outcomes and the ...
Abstract This paper empirically studies the consequences of unobserved heterogeneity on
auction design. Unobserved heterogeneity in the objects for sale induces correlation among
bidders' valuations, which violates the standard modeling assumption of independence. ...
Abstract We introduce and apply a new nonparametric approach to identification and
inference on data from ascending auctions. We exploit variation in the number of bidders
across auctions to nonparametrically identify and estimate useful bounds on seller profit ...

We explore the identification of nonseparable models without relying on the property that the
model can be inverted in the econometric unobservables. In particular, we allow for infinite
dimensional unobservables. In the context of a demand system, this allows each product ...

The measurement of productivity at the plant level is critical to addressing a wide of range of
economic policy issues. A plant's productivity is typically defined as the residual from an
underlying production function, and thus the measurement of productivity is closely tied to ...

We develop an estimator for the parameters of a utility function that has interactions between
the unobserved demand error and observed factors including price. We show that the Berry
(1994)/Berry, Levinsohn, and Pakes (1995) inversion and contraction can still be used to ...

Abstract Why is negative advertising such a prominent feature of competition in the “political

Abstract When unobserved heterogeneity across auctions induces correlation in bidder
valuations, the assumptions of the “standard model” are violated and ascending auctions
are underidentified. We develop techniques to identify the relevant primitives when bidder ...

Applying the insights from the theory of auctions to real world settings requires an empirical

private value auctions, a key primitive of interest is the latent distribution of private values ...

The combined assumptions that the number of bidders participating in an auction is
