As the number of DI recipients grows in many Western countries, evidence on the impact of DI reforms on work resumption and benefit claims from DI and alternative social support programs are of utmost importance to policy makers. Figure 1 shows the number of people receiving DI benefits in 10 OECD countries during the period from 2007 to 2016. While many of the countries show an increasing trend over the observation period, in a small number of countries inflow into DI has decreased due to the major policy reforms implemented in these countries during the last 2 decades. Furthermore, during the period from 2007 to 2015, public spending on incapacity accounted, on average, for 2.06% of the gross domestic product in the OECD countries (OECD, 2018).Through DI reforms, governments introduced different types of measures to reduce the size of DI programs and promote labor participation among sick individuals. Autor and Duggan (2006) and Dal Bianco (2019) distinguish among three types of measures: stricter screening for disability during the sickness period and stricter eligibility criteria for DI so that fewer insured workers qualify, reducing benefit generosity so that incentives of insured workers to seek benefits are reduced, and introducing return-to-work incentives for workers on benefits and for employers. 1 Some of these studies rely on DI reforms to provide causal evidence on the impact of DI policies. With respect to screening for disability during the sickness period, Hullegie and Koning (2018) and Godard et al. (2022) analyze the effects of the Gatekeeper protocol introduced in the Netherlands in 2002, which made reintegration obligations of both employers and employees claiming sickness benefits concrete, making the screening process stricter. With respect to eligibility criteria,
