“…For example, Stiglitz et al [4], Waring [5], and Soupourmas and Ironmonger [6] concluded that traditional indicators such as GDP are insufficient measures of contemporary economic performance. These traditional indicators do not include values other than market production, such as volunteering, which has its own specific value, as noted by Sues and Wilson [7], Emanuele [8], Steinberg [9], Femida and Narasimhan [10], Brown [11], Ross [12] and Montmarquette and Monty [13]. According to Salamon et al [14], Colman [15], Soupourmas and Ironmonger [6] and Novák [16], the value of volunteerism is measurable and it is advisable to measure it.…”
