“…Good examples of studies cited therein include Knowler (2002), Thébaud et al (2014, and Guyader, Talidec, Macher, and Bertignac (2008). For additional examples of the PE approach see Waldo and Paulrud (2017), Kasulo and Perrings (2006), Huang and Perrings (2017), Xu, Brown, Moore, and Currie (2018), Perrings and Walker (1997), Baggio and Perrings (2015), and Erickson, Messner, and Ring (2007). In an interesting application of the PE approach, Quaas and Requate (2013) extend Conrad and Adu-Asamoah (1986) by focusing on consumer preferences for diversity in private consumption of different fish species.…”
