A Comparison of Wage Structures in the United States and Japan: Results from Cell Mean Regressions

This paper discusses three issues in estimating wage regressions by using the aggregated data from the Japanese Basic Survey of Wage Structure (BSWS). The issues include: (1) the order of taking averages and logs, (2) the usage of differently aggregated tables in the BSWS, (3) the treatment of the bonus variable for workers who have just joined a firm. To address them, I present regression results from the US Current Population Survey (CPS). I find that using differently aggregated tables sometimes affects the estimates significantly. I also present the results from wage regressions from the differently aggregated BSWS data.
