Market-based approaches to biodiversity conservation gained popularity in the 1990s. The success of these strategies hinges on, first, the successful creation or expansion of target markets and, second, the beneficial involvement of local stakeholders in these markets so that improved incentives...

Ecotourism, bioprospecting and non-timber product marketing have been promoted recently as market-based instruments for environment protection, but without sound understanding of the resulting net conservation effects. We present evidence on the local conservation effects of recent argan oil...

Work in positive psychology decomposes hope into aspirations, agency, and pathways. Operating in the context of an economic model developed with this framework, we review the literature on hope from philosophy, theology, psychology, and its relationship to emerging work on aspirations in...

A recurring theme in development economics is that risk affects individual production, consumption, exchange, and investment behaviors in ways that ultimately shape income and wealth distributions. Arrow's Decreasing Absolute Risk Aversion conjecture implies that the poor prefer low return, low...

CGD non-resident fellow Jenny Aker and co-authors report on the results from a randomized evaluation of a mobile phone education program (Project ABC) in Niger, in which adult students learned how to use mobile phones as part of a literacy and numeracy class. Overall, students demonstrated...

Technology-driven gains in agricultural productivity and profitability can dramatically improve quality of life for the rural poor in developing countries. Extension efforts to disseminate agricultural technologies typically assume that farmers learn from early adopters who catalyze the...
