Última Social Learning and Parameter Uncertainty in Irreversible Investment----Evidence from Greenhouse Adoption in Northern China AgEcon Wang, Honglin; Reardon, Thomas. This paper introduces social learning into irreversible investment theory through parameter uncertainty, and shows that social learning could reduce parameter uncertainty to facilitate irreversible investment technology adoption. The theoretic model is tested by using household level data from energy saving greenhouse adoption in northern China, and empirical evidences are consistent with the theory: social learning has significantly positive impacts on greenhouse adoption, while market volatility discourages the adoption.

Agriculture in Ethiopia is changing. New players, relationships, and policies are influencing how smallholders access and use information and knowledge. Although this growing complexity suggests opportunities for Ethiopian smallholders, too little is known about how these opportunities can be effectively leveraged to promote pro-poor processes of rural innovation. This paper examines Ethiopia’s smallholder agricultural sector to provide qualitative insights into the interactions between smallholders and other actors in the agricultural sector and the contribution those interactions make to the smallholders’ innovation processes. Case studies of smallholder innovation networks in 10 communities suggest that public sector extension and administration exert a...
