Risk Sharing, Commitment and Information: An experimental analysis
نویسندگان
چکیده
This paper describes and analyzes the results of a unique field experiment especially designed to test the effects of the level of commitment and information available to individuals when sharing risk. We find that limiting exogenously provided commitment is associated with less risk sharing, while limiting information on defections can be associated with more risk sharing. These results can be understood by distinguishing between intrinsic and extrinsic incentives, and by recognizing that social sanctions are costly to inflict or that individuals suffer from time-inconsistent preferences. Comparing the groups formed within our experiment with the real life risk sharing networks in a few villages allows us to test the external validity of our experiment and suggests that the results are salient to our understanding of risk sharing arrangements observed in developing countries. JEL Classification Numbers: C93; D71; D81; O12.

Introduction: Due to the complexity of health services, which require the engagement of different parties for the provision of integrated services, inappropriate network governance models can lead to financial conflicts, lack of transparency of accountabilities for medical errors, and difficulties on multi-professional team working. Therefore, this study aimed to examine factors influencing the...
متن کاملPresenting a semi-quantitative model based on the resiliency engineering management commitment index in assessing the level of preparedness against emergency situations of hospitals in a fuzzy environment (case study: selected Faraja hospitals in 202
Abstract Background and Objective: The main index in resilience engineering is the management commitment index. In this study, a semi-quantitative risk assessment method based on the fuzzy hierarchical analysis method for management commitment index was implemented in evaluating the resilience level of two selected hospitals. Materials and methods: At first, evaluation tools including a 17-qu...
متن کاملAn Experimental Analysis of Group Size, Endowment Uncertainty and Risk Sharing
This paper uses laboratory experiments to examine the relationship between group size and the extent of risk sharing without commitment in an insurance game, where individuals face random idiosyncratic and aggregate shocks to income. We find that the extent of mutual insurance is significantly higher in smaller groups, though contributions to the pool are not close to the theoretical prediction...
متن کاملCompeting pressures of risk and absorptive capacity potential on commitment and information sharing in global supply chains
Organisations are increasingly embedded in global supply chains where the performance and competitiveness of the supply chain has a greater impact on the organisation’s well-being than the organisation’s internal activities. This study examines the countervailing impact of a global supply chain partner’s B2B e-commerce business risk and the partner’s absorptive capacity on an organisation’s wil...
متن کاملA Novel Analysis of Risk Sharing Effects on Income Inequality in Informal Insurances
T his study aims to demonstrate that joining in risk sharing network leads to the reduction in incomes volatility. In this respect, income variance for a group of members in an informal insurance is modelled in which income variance prior to joining risk sharing network and after joining is analyzed statistically. A Monte Carlo simulation technique is used to prove the result. To extend an...
