Incentive theory of the third sector of economy (non-profit organization)

This article aims to provide theoretical model for analyzing challenge of asymmetric information in the third sector of economy (which is the most important challenge,preventing the growth and development of third sector),using the theoretical foundation of contract theory and incentive theory with regard to the special characteristics of third sector derived by its special structure in iran. for this purpose,we introduce a conceptual model that provides a new methodology for analyzing contract theory in the third sector,and offer the optimal contract in every transaction and state. to this end,we put forward the transactional segments of asymmetric information and the possibility of adverse selection and moral hazard problems. then we provide a general incentive theory for the third sector of economy. as a result,it provides a mathematical and theoretical model for optimal contract and makes contribute to solve the adverse selection and moral hazard problems in the third sector transactions. eventually,we use experimental analysis (lingo software) to show that mathematical model is solvable. afterwards we calculate the list of optimal contracts with hypothetical prompters. field study in iran (isfahan) shows that the effect of solving asymmetric information problem is about 73% in the scale of third sector of economy which is significant and notable. © 2016,university of teheran. all rights reserved.
