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

The literature on economic growth and development has focused considerable attention on questions of risk management and the possibility of multiple equilibria associated with poverty traps. We use herd history data collected among pastoralists in southern Ethiopia to study stochastic wealth...

We use herd history data collected among pastoralists in southern Ethiopia to study stochastic wealth dynamics among a poor population. Although covariate rainfall shocks plainly matter, household-specific factors, including own herd size, account for most observed variability in wealth...

This paper uses detailed, transactions-level data and a structural-heteroskedasticity-in-mean model to identify the determinants of livestock producer prices for pastoralists in the drylands of northern Kenya. The empirical results confirm the importance of animal characteristics, periodic...

This paper explores whether bioprospecting can reasonably be expected to change rural incentives to conserve tropical ecosystems. Bioprospecting advocates posit that the prospect of discovery ofbiota of immense commercial worth offers an avenue to increase the valuation of nature and...
