We report on the wellbeing of the young in 31 Ex-Soviet Republics located in Eastern Europe and Central Asia. We find no evidence of the decline in the mental health of the young relative to older people which characterizes Western Europe and English-speaking advanced economies. The mental...

Great achievements in knowledge are produced by older innovators today than they were a century ago. Using data on Nobel Prize winners and great inventors, I find that the age at which noted innovations are produced has increased by approximately 6 years over the 20th Century. This trend is...

In recent years, numerous U.S. cities have enacted taxes on sweetened beverages, but there is relatively little evidence about the effects of these taxes on purchases and consumption. In this paper, we examine the effects of the beverage tax of 1.5 cents per ounce that was implemented in...

Comparing self-reports to administrative data records on diagnosis and prescription drug use, we find that survey respondents under-report mental health conditions 36% of the time when asked about diagnosis and about 20% of the time when asked about prescription drug use. Survey respondents are...

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...

Great scientific output typically peaks in middle age. A classic literature has emphasized comparisons across fields in the age of peak performance. More recent work highlights large underlying variation in age and creativity patterns, where the average age of great scientific contributions has...

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...

We investigate short and long-term effects of early childhood education using variation created by a unique policy experiment in British Columbia, Canada. Our findings imply starting Kindergarten one year late substantially reduces the probability of repeating the third grade, and meaningfully...

In this paper, we investigate the impact of attending school on body weight and obesity. We use school starting age cutoff dates to compare weight outcomes for similar age children with different years of school exposure. As is the case with academic outcomes, school exposure is related to...
