Estimation of the human capital depreciation rate: an international comparison and policy implications in South Korea
This chapter emphasizes skills retention instead of human capital accumulation, which is prominently featured in the social investment literature. The chapter discovers strong empirical support for the so-called use-it-or-lose-it hypothesis, which is that utilising people's skills at work is critical to retaining human capital. Considerable cross-national differences in human capital depreciation across the Organisation for Economic Co-operation and Development (OECD) world point to workplaces as the key site, as differences in workplace organisation may shape differences in how skills are used and, accordingly, differences in human capital depreciation. Considering the differences in skills depreciation, the chapter calls for tailored policy interventions rather than a one-size-fits-all approach. It argues that countries should take different approaches to preserving human capital, depending on their unique patterns of human capital use and depreciation.
