“…Therefore, in the literature, the functions of the co-production in the travel agencies have been considered within different frameworks in terms of supply and demand (Wang and Fesenmaier, 2004;Prebensen and Foss, 2011;Salvado et al, 2011;Wang et al, 2011;Grissemann and Stokburger-Sauer, 2012;Bertella, 2014;Schmidt-Rauch and Schwabe, 2014;Prebensen et al, 2015;Smaliukiene et al, 2015;Tseng and Chiang, 2016;Arıca and Kozak, 2018). In the researches, the effect of the customer participation in production on the provided and perceived service outputs has been frequently examined (Wang and Fesenmaier 2004;Prebensen and Foss, 2011;Salvado et al, 2011;Wanget al.2011;Grissemann and Stokburger-Sauer, 2012;Prebensen and Dahl, 2013;Tseng and Chiang 2016). In the significant part of the researches, it was found that the co-production affected the service outputs in different aspects (Wang and Fesenmaier 2004;Salvado et al, 2011;Grissemann and Stokburger-Sauer, 2012;Prebensen and Dahl, 2013;Tseng and Chiang 2016;Arıca and Kozak, 2018).…”
