Factor market failures can limit adoption of profitable technologies. We leverage a plot-level spatial regression discontinuity design in the context irrigation use by farmers provided free access to water. Using boosts profits 43–62 percent. Yet, only irrigate 30 percent plots because labor costs. demonstrate inefficient use, showing irrigating one plot reduce their on other plots. This ineffi...

BACKGROUND Organic solvents are known as a group of organic compounds, widely used in industry and to which many workers are exposed. Neurotoxicity is one of the most important complications of the chronic exposure to the solvents and may causes neurobehavioral disorders in workers. We have studied the frequency of neurobehavioral disorders in workers exposed to organic solvents in one of the p...

Can targeting information to network-central farmers induce more adoption of a new agricultural technology? By combining social network data and field experiment in 200 villages Malawi, we find that central is important spur the diffusion process. We also provide evidence one explanation for why centrality matters: process governed by complex contagion. Our results are consistent with model whi...

The receptor of the macrophage colony-stimulating factor 1 (CSF1R) belongs to a subfamily of receptor tyrosine kinases (Roberts et al., 1988; Yarden and Ullrich, 1988). The CSF1R gene is in close vicinity to the PDGFR1 gene (platelet-derived growth factor receptor 1) which is located only a few hundred basepairs proximal in a head-to-tail orientation. Hampe et al. (1989) demonstrated that the h...

Much has been written on the determinants of input and technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of ...

Article history: Received 17 September 2012 Received in revised form 12 September 2013 Accepted 14 September 2013 Available online 26 September 2013 This paper aims at an important gap in the literature, which has not modeled the effect of social learning in a real option context and examined uncertainty-reduction measures through social learning. This paper addresses the gap by modeling social...

We describe various computing techniques for tackling chessboard domination problems and apply these to the determination of domination and irredundance numbers for queens’ and kings’ graphs. In particular we show that γ(Q15) = γ(Q16) = 9, confirm that γ(Q17) = γ(Q18) = 9, show that γ(Q19) = 10, show that i(Q18) = 10, improve the bound for i(Q19) to 10 ≤ i(Q19) ≤ 11, show that ir(Qn) = γ(Qn) fo...

We assess farmers' incentives and the conditioning factors for adoption of agricultural technologies under climate risk and evaluate its impact on food security in Niger. Results show that while the use of modern inputs and organic fertilizers improves productivity, results are unclear for crop residues. Results also show that factors driving modern input use are different than those of crop re...

This paper analyzes the interaction between farmer training in pest management and effects on acute pesticide poisoning and populations of beneficial insects in Nicaragua. Using farm level data from Nicaraguan bean growers, including graduates of Farmer Field Schools (FFS), other integrated pest management (IPM) outreach methods, and farmers without exposure to IPM, we found that small farmers ...
