Learning About a New Technology: Pineapple In Ghana AgEcon
Conley, Timothy G.; Udry, Christopher R..
This paper investigates the role of social learning in the diffusion of a new agricultural technology in a developing country: Ghana. We use unique data on farmers’ communication patterns to define each individual’s information neighborhood, the set of others from whom he might learn. Our empirical strategy is to test whether farmers change their input decisions to align with those of their neighbors who were successful in previous periods. We present evidence that farmers adopt successful neighbors’ practices, conditional on many potentially confounding factors including the physical proximity of plots, credit arrangements, clan membership, and soil characteristics.

Microfinance: Does It Hold Its Promises? A Survey of Recent Literature AgEcon
Khawari, Aliya.
Poverty alleviation has been the main target of developmental projects world-wide. However, only a few ideas have stirred so much attention in the last two decades as that of the provision of microfinance through specialised institutions. This paper provides a survey of the vast literature that has developed in this field. Though most of the evidence and literature on the subject appears self-praising, nonetheless there is much more to the concept than one can imagine. The establishment of microfinance institutions (MFIs) world-wide for the provision of collateral free loans to the poor through mechanisms and instruments not known to normal commercial banks has set new milestones in the field of financial services. With 900 million households in the less...

Poverty Comparisons with Endogenous Absolute Poverty Lines AgEcon
Simler, Kenneth R.; Arndt, Channing.
The objective of measuring poverty is usually to make comparisons over time or between two or more groups. Comm on statistical inference methods are used to determine whether an apparent difference in measured poverty is statistically significant. Studies of relative poverty have long recognized that when the poverty line is calculated from sample survey data, both the variance of the poverty line and the variance of the welfare metric contribute to the variance of the poverty estimate. In contrast, studies using absolute poverty lines have ignored the poverty line variance, even when the poverty lines are estimated from sample survey data. Including the poverty line variance could either reduce or increase the precision of poverty estimates, depending on...

Competition, Regulation and Privatisation of Electricity Generation in Developing Countries: Does the Sequencing of the Reforms Matter? AgEcon
Zhang, Yingang; Parker, David; Kirkpatrick, Colin.
Recent years have seen countries introducing reform of their utility industries with a view to promoting private ownership and competition. This paper studies the effect of the sequencing of privatisation, competition and regulation reforms in electricity generation using data from 25 developing countries for the period 1985 to 2001. A fixed effects panel data model is used. The study finds that establishing an independent regulatory authority and introducing competition before privatisation is correlated with higher electricity generation, higher generation capacity and, in the case of the sequence of competition before privatisation, improved capital utilisation.
