Payment for ecosystem services and motivational crowding: Experimental insights regarding the integration of plural values via non-monetary incentives

Incentives based on extrinsic motivations such as Payments for ecosystem Services (PES) could negatively affect intrinsic motivations (i.e., motivational crowding-out). This effect may be evidenced when conservation levels, after PES intervention, decline relative to those existing before PES implementation. However, still few experimental studies have assessed PES effects on motivations once economic incentives are missing. Moreover, experimental research still lacks insights on PES designs that may reduce the risk of motivational crowding-out. This paper aims to assess the post-intervention effects of integrating plural values via non-monetary incentives (i.e. environmental awareness, social recognition) into PES design. We conducted a lab-in-the-field experiment followed by a questionnaire involving 120 participants in rural Cali, Colombia. We use non-parametric and Differences in Differences regression analysis to show that integrating plural values (intrinsic and relational) via non-monetary incentives may have a long-lasting effect on conservation (motivational crowding-in) in comparison with a PES alone. We did not find strong evidence of PES motivational crowding-out. We conclude that PES effectiveness and equity-related outcomes could be fostered by integrating the multiple ways of knowing, relating and caring for Nature.
