Economists wish to use data on matches to learn about the structural primitives that govern sorting. I show how to use equilibrium data on who matches with whom for semiparametric estimation of match production functions in many-to-many, two-sided matching games with transferable utility....

The deferred acceptance algorithm proposed by Gale and Shapley (1962) has had a profound influence on market design, both directly, by being adapted into practical matching mechanisms, and, indirectly, by raising new theoretical questions. Deferred acceptance algorithms are at the basis of a...

This examination of the role and potential for replication in economics points out the paucity of both pure replication -- checking on others' published papers using their data -- and scientific replication -- using data representing different populations in one's own work or in a Comment....

We examine the determinants of election as Fellow of the Econometric Society, an example of voting within a group to confer honor on some members and perhaps achieve additional status for the entire group. Using data from annual elections from 1990-2000, we find that objective measures of...

Over the past decade there has been a decline in the fraction of papers in top economics journals written by economists from the highest-ranked economics departments. This paper documents this fact and uses additional data on publications and citations to assess various potential explanations....

Toys. The impact of computers on productivity has been examined directly on macro data and indirectly (on wages) using microeconomic data. This study examines the direct impact on the productivity of scholarship by considering how high technology might alter patterns of coauthoring of articles...

This paper develops a model of evolving standards for academic publishing. It is motivated by the increasing tendency of academic journals to require multiple revisions of articles and by changes in the content of articles. Papers are modeled as varying along two quality dimensions: q and r. The...

Over the last three decades there has been a dramatic increase in the length of time necessary to publish a paper in a top economics journal. This paper documents the slowdown and notes that a substantial part is due to an increasing tendency of journals to require that papers be extensively...

A large literature following Hirsch (2005) has proposed citation-based indexes that could be used to rank academics. This paper examines how well several such indexes match labor market outcomes using data on the citation records of young tenured economists at 25 U.S. departments. Variants of...

This paper is a non-technical and somewhat philosophical essay, that seeks to investigate the relationship between economics and reality. More precisely, it asks how reality in the form empirical evidence does or does not influence economic thinking and theory. In particular, which role do...
