It uses data from the Korean Labor and Income Panel Study (KLIPS) and applies two wage imputation methods to correct for selection into full-time, regular employment. Specifically, it estimates the wage offers of those not in full employment using wages from proximate years and a semi-parametric reweighting method. The findings show that ignoring sample selection bias causes wage offers to be overestimated, particularly for women, as those with lower wage offers are more likely to opt out full employment. Consequently, selection adjustments increase wage gaps in both 2001 and 2017. Positive selection weakens for women during this period which is associated with changes in education and marriage. Therefore, adjustments increase gaps more in 2001 than in 2017, leading to larger decreases in the wage gaps over time. This implies that the relative progress in labor market opportunities for women is larger than previously estimated. Finally, unadjusted gaps suggest gender disparities were largest in low-paid positions in 2001 but high-paid positions 2017, whereas adjusted gaps suggest they were largest in medium-paid positions in both years. Overall, the findings highlight the importance of accounting for sample selection bias when assessing gender wage disparities.</div></div>","PeriodicalId":46744,"journal":{"name":"Japan and the World Economy","volume":"77 ","pages":"Article 101345"},"PeriodicalIF":1.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine the interactions between age-skill labor groups and technical capital represented by ICT and industrial robots in 12 OECD countries from 2008 to 2020. Using sector-level data, we find that a higher ICT intensity enhances relative labor productivity in industries employing a large share of low-skilled older workers, while robots exhibit complementarities with high-skilled older workers. Moreover, when ICT and robots are jointly adopted, the relative productivity differences across age-skilled groups are shrinked, particularly narrowing the gap between workers of the same age group but with different skill levels. The effects, however, are highly heterogeneous across countries and industries. In countries with high population aging and widespread robot use, the interactions between technological capital and labor differ markedly. Furthermore, robots tend to exhibit stronger complementarities with workers in capital-intensive industries, while ICT shows complementary effects with older workers across both skill groups in labor-intensive industries.</div></div>","PeriodicalId":46744,"journal":{"name":"Japan and the World Economy","volume":"76 ","pages":"Article 101335"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145614567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
