“…For European countries, we cross check our data set with the NBER series on social security programs and retirement around the world, including Fraikin, Jousten, and Lefebvre (2018) for Belgium, Bingley, Gupta, Jorgensen, and Pedersen (2014) for Denmark, Lassila and Valkonen (2002) for Finland, Blanchet, Bozio, Rabate, and Roger (2019) for France, Franco (2002) and Brugiavini and Peracchi (2014) for Italy, Vegas Sánchez, Argimón, Botella, and González (2013) and Garcia-Gomez, Garcia-Mandico, Jimenez-Martin, and Castello (2018) for Spain, and Blake (2002) and Banks and Emmerson (2018) for the United Kingdom. For non-European countries, we use Nielson (2010) and Herscovitch and Stanton (2008) for Australia, and John and Willmore (2001) for New Zealand as reference. Also, we cross check our data set with Beetsma, Klaassen, Romp, and van Maurik (2020), in which the authors compile pension reform measures using the NATLEX database of the International Labor Organization, the International Social Security Association database, the European Commission's Labour Market Reform database, and other sources.…”
