    Career penalties of long term-care provision

    It is the aim of the project to analyze the labor market consequences of informal care provision. For the identification we follow the literature on childcare penalties (see Kleven et al. 2019) to quantify the short- and long-run career costs of childcare. Rellstab et al. (2020) for the Netherlands and Halla et al. (2021) for Austria have applied this framework to estimate the career effects for...

    Long term care and migration

    Organizing long-term care (LTC) is one of the most pressing challenges for the coming years, both societally and politically. Across OECD countries, the proportion of individuals aged 80 and above will increase from an average of nearly five to almost ten percent of the population by 2050 (OECD, 2020). This rapid aging will have sizable implications for the demand and provision of LTC. The issue...
