Coalitions for sustainable consumption: Understanding the emergence of shared ownership in an Agent-Based Model
Sharing ownership of goods, like cars or drills, used by a single owner for a small fraction of their life-time, can mitigate environmental impacts. But are consumers ready to give up individual property rights on underutilised goods? We propose a simple model to study conditions favouring consumers purchasing a private good in coalition rather than individually. By exploring the model parameter space, encompassing characteristics and preferences of heterogeneous consumers, those of the private good and of a public service that offers the same service of the good, we identify the emergence of shared ownership. It predominantly occurs under niche conditions: among lower-income consumers with above-average demand, especially when the shared good is relatively small and purchasable in small coalitions — which have lower coordination challenges. Shared ownership reduces the net number of goods in an economy and production-related environmental impact, even in the absence of consumers’ sustainability concerns. Policies reducing the relative price of the shared purchase accelerate the transition to a more sustainable shared consumption. However, we do not find any impact of shared ownership in reducing inequality in accessing goods.
期刊介绍:
The Journal of Economic Behavior and Organization is devoted to theoretical and empirical research concerning economic decision, organization and behavior and to economic change in all its aspects. Its specific purposes are to foster an improved understanding of how human cognitive, computational and informational characteristics influence the working of economic organizations and market economies and how an economy structural features lead to various types of micro and macro behavior, to changing patterns of development and to institutional evolution. Research with these purposes that explore the interrelations of economics with other disciplines such as biology, psychology, law, anthropology, sociology and mathematics is particularly welcome.
