|August 2014||Does Labor Legislation Benefit Workers? Well-Being after an Hours Reduction|
with Daniel S. Hamermesh, Jungmin Lee: w20398
Are workers in modern economies working "too hard"--would they be better off if an equilibrium with fewer work hours were achieved? We examine changes in life satisfaction of Japanese and Koreans over a period when hours of work were cut exogenously because employers suddenly faced an overtime penalty that had become effective with fewer weekly hours per worker. Using repeated cross sections we show that life satisfaction in both countries may have increased relatively among those workers most likely to have been affected by the legislation. The same finding is produced using Korean longitudinal data. In a household model estimated over the Korean cross-section data we find some weak evidence that a reduction in the husband's work hours increased his wife's well-being. Overall these resu...

|December 2012||A Gift of Time|
with Jungmin Lee, Daniel S. Hamermesh: w18643
How would people spend time if confronted by permanent declines in market work? We identify preferences off exogenous cuts in legislated standard hours that raised employers' overtime costs in Japan around 1990 and Korea in the early 2000s. We estimate the probability that an individual was affected by the reform and relate it to changes in time use based on time diaries. Reduced-form estimates show that the direct effect on a newly-constrained worker was a substantial reduction in market time, with the freed-up time in Japan reallocated to leisure, but in Korea also showing some impact on household production. Simulations using GMM estimates of a Stone-Geary utility function defined over time use suggest no effect on household production in either country. Estimation of a household mod...

|December 2011||Aggregate Impacts of a Gift of Time|
with Jungmin Lee, Daniel S. Hamermesh: w17649
How would people spend additional time if confronted by permanent declines in market work? We examine the impacts of cuts in legislated standard hours that raised employers' overtime costs in Japan around 1990 and Korea in the early 2000s. Using time-diaries from before and after these shocks, we show that these shocks were effective--per-capita hours of market work declined discretely. The economy-wide drops in market work were reallocated solely to leisure and personal maintenance. In the absence of changing household technology a permanent time gift leads to no increase in time spent in household production by the average individual.

|December 2001||Attrition Bias in Economic Relationships Estimated with Matched CPS Files|
with David Neumark: w8663
Short panel data sets constructed by matching individuals across monthly files of the Current Population Survey (CPS) have been used to study a wide range of questions in labor economics. Such panels offer unique advantages. But because the CPS makes no effort to follow movers, these panels exhibit significant attrition, which may lead to bias in longitudinal estimates using matched CPS files. Because the Survey of Income and Program Participation (SIPP) uses essentially the same sampling frame and design as the CPS, but makes substantial efforts to follow individuals that move, we use the SIPP to construct 'data-based' rather than 'model-based' corrections for bias from selective attrition. The approach is applied to a couple of standard economic relationships that have been studied with ...
