This paper analyses the effect of a set of irrigation rehabilitation projects conducted over the last 10 years in Peru. The projects were conducted without the aim or the tools for a full-fledged impact evaluation. Nevertheless, this paper attempts an evaluation through the use of alternative data sources such as household surveys and geographic information, a strategy of identification of beneficiaries and control households based on spatial proximity to the projects' sites, and an econometric approach consisting of a double-differencing technique. The empirical analysis is guided and interpreted with the help of a theoretical model that considers the effects of an irrigation project on the distribution of production, employment and income for different types of landowners. The paper concludes that the irrigation projects implemented in Peru had a positive impact on intended beneficiary households, but not in the way it could have been simplistically expected.
This paper uses a rural household survey dataset collected in 2006 and 2008 to investigate the impact of a marketbased land resettlement project in southern Malawi. The program provided a conditional cash and land transfer to poor families to relocate to larger plots of farm land. The average treatment effect of the program is estimated using a difference-in-difference matching technique based on propensity score matching; qualitative information complement the analysis to ensure unobservable characteristics do not bias the findings. As expected, the results show a significant effect on landholdings and agricultural production, with land size increasing and
The Impact Evaluation Series has been established in recognition of the importance of impact evaluation studies for World Bank operations and for development in general. The series serves as a vehicle for the dissemination of findings of those studies. Papers in this series are part of the Bank's Policy Research Working Paper Series. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.
This impact evaluation uses econometric techniques to assess the social and economic impact of an IFC investment in Ecogreen Oleochemicals in Indonesia. This investment doubled the capacity of an Ecogreen plant in the Kabil district on the island of Batam. We use the synthetic control methodology and household level survey data from 1994-2009 to assess whether measureable impacts are observed after the investment. We find that monthly expenditures per capita in the Kabil district grew by 165,000
