This paper provides field experiment?based evidence on the potential additional forest carbon sequestration that cleaner and more fuel-efficient cookstoves might generate. The paper focuses on the Mirt (meaning ?best?) cookstove, which is used to bake injera, the staple food in Ethiopia. The...

Improving access to affordable and reliable energy services for cooking is essential for developing countries in reducing adverse human health and environmental impacts hitherto caused by burning of traditional biomass. This paper reviews empirical studies that analyze choices of fuel and...

In Africa, farmers have been reluctant to take up new varieties of staple crops developed to boost smallholder yields and rural incomes. Low fertilizer use is often mentioned as a proximate cause, but some believe the problem originates with incomplete input markets. As a remedy, African...

We provide a general theoretical characterization of how firms' technology choice on a technology frontier determines the long-run elasticity of substitution between capital and labor. We show that the shape of the frontier determines factor shares and the elasticity of substitution between...

In recent years a phenomenon called "frugal innovation" has increasingly gained traction in the scholarly discourse; and as research reveals, it is often brought in connection with India. Apparently, India has quietly acquired the role of a pioneer for innovations that aim at combining...

The authors develop an endogenous growth model that combines structural change with repeated product improvement. That is, the technologies in one sector of the model become not only increasingly capital-intensive, but also progressively productive over time. Application of the basic model to...
