Many development programs are based on short-term interventions, either because of external funding constraints or because it is assumed that impacts persist post program termination ("sustainability"). Using a novel randomized phase-out research method, we provide experimental tests of the...

The adoption of modern technologies in agriculture is crucial for improving productivity of poor farmers and poverty reduction. However, the adoption of modern technology has been disappointing. The role of value chains in technology adoption has been largely ignored so far, despite the dramatic...

This study assessed the determinants of intensity of adoption of Improved Rice Varieties (IRVs) and the effect of market participation on farmers' welfare in Nigeria using the Tobit and Heckman two-stage models, respectively. The sample consists of crosssectional data of 600 rice farmers...

This paper evaluates causal impacts of a large-scale agricultural extension program for smallholder women farmers on food security in Uganda through a regression discontinuity design that exploits an arbitrary distance-to-branch threshold for village program eligibility. We find eligible farmers...

This paper presents a descriptive analysis on the ownership of different types of technology - both agricultural machinery and information technology - within households in rural areas of Vietnam. We find that there has been little development in the ownership of agricultural machinery, but a...

The objective of this study is to obtain a better understanding of the current rice production condition in Myanmar through efficiency analysis, especially, to examine the impact of farm mechanization on Myanmar rice production efficiency. For representation of efficiency and the determinants,...

Innovations are fast changing the agricultural landscape driven by the increasing need to shift towards sustainable practices without sacrificing the productivity and profitability of farming. Innovations in technology, institutions, processes, and products have contributed to the growth of...

This paper presents the results of an impact evaluation for the CRIAR program, implemented in rural areas in Bolivia. The objective of this program is to increase the agricultural income and food security of smallholder farmers through productivity gains that result from technological adoption....
