peer to peer product sharing implications for ownership usage and social welfare in the sharing economy
Management Science, 2019Co-Authors: Saif Benjaafar, Guangwen Kong, Costas CourcoubetisAbstract:We describe an equilibrium model of peer-to-peer product sharing, or collaborative consumption, where individuals with varying usage levels make decisions about whether or not to own a homogeneous product. Owners are able to Generate Income from renting their products to nonowners while nonowners are able to access these products through renting on an as-needed basis. We characterize equilibrium outcomes, including ownership and usage levels, consumer surplus, and social welfare. We compare each outcome in systems with and without collaborative consumption and examine the impact of various problem parameters. Our findings indicate that collaborative consumption can result in either lower or higher ownership and usage levels, with higher ownership and usage levels more likely when the cost of ownership is high. Our findings also indicate that consumers always benefit from collaborative consumption, with individuals who, in the absence of collaborative consumption, are indifferent between owning and not own...

Peer-to-Peer Product Sharing: Implications for Ownership, Usage and Social Welfare in the Sharing Economy
SSRN Electronic Journal, 2015Co-Authors: Saif Benjaafar, Guangwen (crystal) Kong, Xiang Li, Costas CourcoubetisAbstract:We describe an equilibrium model of peer-to-peer product sharing, or collaborative consumption, where individuals with varying usage levels make decisions about whether or not to own. Owners are able to Generate Income from renting their products to non-owners while non-owners are able to access these products through renting on as needed basis. We characterize equilibrium outcomes, including ownership and usage levels, consumer surplus, and social welfare. We compare each outcome in systems with and without collaborative consumption and examine the impact of various problem parameters including rental price, platform's commission fee, cost of ownership, owner's moral hazard cost, and renter's inconvenience cost. Our findings indicate that, depending on the rental price, collaborative consumption can result in either lower or higher ownership and usage levels, with higher ownership and usage levels more likely when the cost of ownership is high. We show that consumers always benefit from collaborative consumption, with individuals who, in the absence of collaborative consumption, are indifferent between owning and not owning benefitting the most. We also show that the platform's profit is not monotonic in the cost of ownership, implying that a platform is least profitable when the cost of ownership is either very high or very low.

poverty persistence and intra household heterogeneity in occupations evidence from urban ethiopia
Oxford Development Studies, 2015Co-Authors: Yonas AlemAbstract:Previous studies of poverty in developing countries have to a great extent focussed on the characteristics of the household head and used these as proxies for the underlying ability of the household to Generate Income. This paper uses five rounds of panel data to investigate the persistence of poverty in urban Ethiopia, with a particular focus on the role of intra-household heterogeneity in occupations. Dynamic probit and system generalised method of moments regression results suggest that international remittances and labour market status of non-head household members are important determinants of households' poverty status. Results also show that controlling for these variables and the “initial conditions problem” encountered in nonlinear dynamic probit models reduces the magnitude of estimated poverty persistence significantly for urban Ethiopia. These findings have important implications for identifying the poor and formulating effective poverty reduction and targeting strategies.

This paper uses five rounds of panel data to investigate the persistence of poverty in urban Ethiopia with a particular focus on the role of intra-household heterogeneity in occupations. Dynamic probit and system GMM regression results suggest that international remittances and labor market status of non-head household members are important determinants of households' poverty status. Results also show that controlling for these variables and the initial conditions problem encountered in non-linear dynamic probit models reduces the magnitude of estimated poverty persistence significantly for urban Ethiopia. These findings have important implications for identifying the poor and formulating effective poverty reduction and targeting strategies.

credit market constraints consumption smoothing and the accumulation of durable production assets in low Income countries investments in bullocks in india
Journal of Political Economy, 1993Co-Authors: Mark R Rosenzweig, Kenneth I WolpinAbstract:In this paper we formulate and estimate a finite-horizon, structural dynamic model of agricultural investment behavior that incorporates the major features of low-Income agricultural environments: Income uncertainty, constraints on borrowing and rental markets, and the use of investment assets to Generate Income and smooth consumption. The model is fit to longitudinal Indian household data on farm profits, bullock stocks, and pump sets. The estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks, agricultural profits, and welfare associated with complete markets and bullock liquidity and with second-best policies that provide assured sources of Income to farmers and weather insurance.
