Water resources transfers through southern African food trade: water efficiency and climate signals
We combine global hydrological model simulations with international food trade data to quantify the water resources embedded in international food trade in southern Africa and with the rest of the world, from 1986–2011. read more »
Well-being dynamics and poverty traps
This paper reviews the theoretical and empirical evidence on single and multiple equilibria poverty traps at the macro, meso, and, especially, micro levels. read more »
Spaces for Agreement: A Theory of Time-Stochastic Dominance and an Application to Climate Change
Many investments involve both a long time horizon and risky returns. Making investment decisions thus requires assumptions about time and risk preferences. Such assumptions are frequently contested, particularly in the … read more »
Robustness of norm-driven cooperation in the commons
We assess the robustness of cooperation to environmental variability in a stylized model of a community that harvests a shared resource. read more »
Asymmetric industrial energy prices and international trade
This paper measures the response of bilateral trade flows to differences in industrial energy prices across countries. Using a rich panel dataset with 42 countries, 62 manufacturing sectors over 16 … read more »
Integrated Assessment of no-Regret Climate Change Adaptation Options for Reservoir Catchment and Command Areas
In this study, we integrate participatory and modelling approaches for evaluation of reservoir catchment and command area no-regret options addressing water availability and demand in the Kangsabati river basin. read more »
Rights to the forest, REDD+ and elections: Mining in Guyana
This paper examines the impact of electoral cycles and the introduction of Reducing Emissions from Deforestation and Degradation (REDD+) policy upon the holding of small-scale mining property rights in Guyana. … read more »
Invention and diffusion of water supply and water efficiency technologies: insights from a global patent dataset
This paper identifies over 50,000 patents filed worldwide in various water-related technologies between 1990 and 2010, distinguishing between those related to availability (supply) and conservation (demand) technologies. Patenting activity is … read more »
Flooded cities
Does economic activity relocate away from areas that are at high risk of recurring shocks? We examine this question in the context of floods, which are among the costliest and … read more »
Collective intertemporal choice: time consistency vs. time invariance
We study collective choice when individuals have heterogeneous discounted utilitarian preferences. Two attractive properties of intertemporal preferences are indistinguishable for individuals, but have dramatically different implications for collective choice. Time … read more »
