“…Other authors have worked with social expenditure variables, some using classical indicators in the analysis of social security benefits, such as coverage and replacement rates (Cornellisse & Goudswaard, 2002; Johnson, 1999), and others referring exclusively to aggregate social expenditure levels. Of the latter, some merely offer static comparisons (Barrada, 1997; Boscá, Fernández & Taguas, 1997; Fernández, 1993; Greeve, 1996), while others offer a dynamic perspective (Alber & Standing, 2000; Alonso, Galindo & Sosvilla‐Rivero, 1997; Castles, 2001; Herce, Sosvilla‐Rivero & de Lucio, 1998).…”
