I ask generally whether a country can benefit from the temporary importation of human capital, and specifically whether a program that attracts large groups of academic visitors to a distant country benefits it by generating additional scholarly research on local issues. Using the list of...

This study examines the various uses of subjective outcomes as a focus of interest for economists. It outlines the possible channels by which economists can usefully add to what are already massive literatures on such outcomes in the other social sciences. Generally we contribute little if we...

Routine - maintaining the same schedule from day to day - saves time. It is also boring and inherently undesirable. As such, the amount of routine a person engages in is partly an economic outcome, with variations in routine generated by variations in the price of time, household income and the...

I argue for increased reliance on non-U.S. data and policy evaluations to understand basic labor- market parameters and to predict the effects of changes in U.S. labor-market policies. Foreign experiences generate exogenous shocks to labor costs that create unusual opportunities to measure...

I describe and compare sources of data on citations in economics and the statistics that can be constructed from them. Constructing data sets of the post-publication citation histories of articles published in the "Top 5" journals in the 1970s and the 2000s, I examine distributions and life...

The previously documented trend toward more co- and multi-authored research in economics is partly (perhaps 20 percent) due to different research styles of scholars in different birth cohorts (of different ages). Most of the trend reflects profession-wide changes in research style. Older...

Presenting data on all full-length articles published in the three top general economics journals for one year in each of the 1960s through 2010s, I analyze how patterns of co-authorship, age structure and methodology have changed, and what the possible causes of these changes may have been. The...

Using several microeconomic data sets from the United States and the Netherlands, and the examples of height and beauty, this study examines whether: 1) Absolute or relative differences in a characteristic are what affect labor-market and other outcomes; and 2) The effects of a characteristic...

Product diversity pervades every modern marketplace, and economists have devoted substantial attention to firms' decisions about the supply of variety. This study looks at the consumer's side by discussing the demand for variety. Using the framework of the home-production model, we trace...

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...
