This paper uses both a global and local perspective to assess the impacts of climate change on the Yemeni economy, agriculture, and household income and food security. The major impact channels of climate change are through changing world food prices as a result of global food scarcities,...

Carbon markets are substantial and they are expanding. There are many lessons from experiences over the past eight years -- fewer free allowances, better management of market-sensitive information, and a recognition that trading systems require adjustments that have consequences for market...

On efficiency grounds, the economics community has to date tended to emphasize price-based policies to address climate change -- such as taxes or a “safety-valve” price ceiling for cap-and-trade -— while environmental advocates have sought a more clear quantitative limit on emissions. This...

"Global climate change poses great risks to poor people whose livelihoods depend directly on the use of natural resources. Mitigation of the adverse effects of climate change is a high priority on the international agenda. Carbon trading, under the Kyoto Protocol as well as outside the protocol,...

"This paper investigates the impact of climate variability on maize yield in the Limpopo Basin of South Africa using the Generalized Maximum Entropy (GME) estimator and Maximum Entropy Leuven Estimator (MELE). Precipitation and temperature were used as proxies for climate variability, which were...

Seminal work by Weitzman (1974) revealed that prices are preferred to quantities when marginal benefits are relatively flat compared to marginal costs. We extend this comparison to indexed policies, where quantities are proportional to an index, such as output. We find that policy preferences...

Improving soil carbon through conservation agriculture in developing countries may generate some private benefits to farmers, as well as sequester carbon emissions, which is a positive externality to society. Leaving crop residue on the farm has become an important option in conservation...

Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is...
