Impact of modern agricultural technologies on smallholder welfare: evidence from tanzania and ethiopia
TL;DR: In this paper, the potential impact of adoption of improved legume technologies on rural household welfare measured by consumption expenditure in rural Ethiopia and Tanzania was evaluated by using endogenous switching regression, which helps to estimate the true welfare effect of technology adoption by controlling for the role of selection problem on production and adoption decisions.

The Adoption and Impact of Soil and Water Conservation Technology: An Endogenous Switching Regression Application
Awudu Abdulai,Wallace E. Huffman +1 more
TL;DR: In this paper, the authors identify the factors that affect farmers' decisions to adopt soil and water conservation technology in Africa and how this technology impacts farm yields and net returns, and show that adoption of this technology increases rice yields and nets significantly.

Adoption of improved wheat varieties and impacts on household food security in Ethiopia
TL;DR: This paper evaluated the impact of adoption of improved wheat varieties on food security using a recent nationally-representative dataset of over 2000 farm households in Ethiopia and found that adoption increases food security and farm households that did adopt would also have benefited significantly had they adopted new varieties.

The central role of the propensity score in observational studies for causal effects
TL;DR: The authors discusses the central role of propensity scores and balancing scores in the analysis of observational studies and shows that adjustment for the scalar propensity score is sufficient to remove bias due to all observed covariates.

Some practical guidance for the implementation of propensity score matching
Marco Caliendo,Sabine Kopeinig +1 more
TL;DR: Propensity score matching (PSM) has become a popular approach to estimate causal treatment effects as discussed by the authors, but empirical examples can be found in very diverse fields of study, and each implementation step involves a lot of decisions and different approaches can be thought of.

Propensity score-matching methods for nonexperimental causal studies
Rajeev Dehejia,Sadek Wahba +1 more
TL;DR: In this article, the authors consider causal inference and sample selection bias in nonexperimental settings in which few units in the nonex-experiment comparison group are comparable to the treatment units, and selecting a subset of comparison units similar to treatment units is difficult because units must be compared across a high-dimensional set of pre-treatment characteristics.
World development report 2008 : agriculture for development
TL;DR: Agriculture is a vital development tool for achieving the Millennium Development Goal that calls for halving by 2015 the share of people suffering from extreme poverty and hunger as mentioned in this paper, which is the overall message of this year's World Development Report (WDR), the 30th in the series.
