“…Researchers have drawn a causal link between the recent reforms in hospital payment schemes and the concomitant trends in healthcare expenditure and mortality (Cutler, 1993;Yip and Eggleston, 2001;Moreno-Serra and Wagstaff, 2010). The various payment schemes operating in developed countries create different incentives for hospital care provision (Cylus and Irwin, 2010;Ellis and Miller, 2008), which, in turn, may influence healthcare expenditures. 1 Moreover, several studies using OECD country panel data have indicated that healthcare expenditure positively affects life expectancy, even when several confounders are controlled for (Elola et al, 1995;Or, 2000;Lichtenberg, 2002;Shaw et al, 2002;Miller and Frech, 2002;Berger and Messer, 2002;Hitiris and Posnett, 1992;Nixon and Ulmann, 2006).…”
