“…Many lump all different types of temporary employment together (D'Addio and Rosholm, 2005;de Graaf-Zijl et al, 2011;Esteban-Pretel et al, 2011;McGinnity et al, 2005;Remery et al, 2002;Steijn et al, 2006). Others focus only on one specific type of temporary employment, typically fixed-term contracts (Autor and Houseman, 2010;Hopp et al, 2016;Ichino et al, 2008;Pavlopoulos, 2013), while in some cases the type of temporary employment that is studied is not clearly defined (Faccini, 2014;Giesecke and Groβ, 2003;Picchio, 2008;Wolbers, 2010). If any variation in the types of temporary employment is allowed, this is mostly limited to the distinction between fixed-term contracts and seasonal/casual work, which are then studied separately (Addison et al, 2015;Booth et al, 2002;de Lange et al, 2013;Leschke, 2009).…”
