Convergence in global environmental performance: assessing heterogeneity [PDF]
Environmental Economics and Policy Studies, 2017 This paper examines convergence in environmental/carbon performance by constructing a measure based on production theory, where production processes explicitly result in the production of two outpu ...

Risk Preferences Under Heterogeneous Environmental Risk [PDF]
SSRN Electronic Journal, 2012 We study risk preferences and their determinants for commercial cattle farmers in Namibia who are subject to high and heterogeneous precipitation risk, using data from questionnaire and field experiments, simulated data for on-farm precipitation risk and data on famers’ previous place of residence. We find that the relationship between risk preferences
