“…For instance, a number of studies have reported significant and positive income effects on trust (e.g., Glaeser et al, 2000;Karlan, 2005;Schechter, 2007;Johansson-Stenman et al, in press). Several studies have also reported that education of the respondent has positive and significant effects on trust (e.g., Frewer et al, 1999;Holgado et al, 2000;Bellemare and Kröger, 2007;Lobb et al, 2007;Zerfu et al, 2009), while others have found education to show negative effects (e.g., Johansson-Stenman et al, in press). Similarly, some studies show that older respondents have higher levels of trust than younger ones (Zerfu et al, 2009), while others report a decreased level of trust with increase in age (e.g., Huffman et al, 2004).…”
