Most research in queuing has focused on the optimisation of performance and equilibrium analysis, with little attention to the understanding of how managers actually make decisions. In this paper, we use an experimental set-up to investigate the decision-making process in a queuing capacity expansion problem, in the presence of capacity adjustment delays. The experiment represents a queuing system with one facility and virtual customers who decide whether or not to patronise the facility.

There is tension in developing countries between financial incentives to clear forests and climate regulation benefits of preserving trees. Now research shows that paying private forest owners in Uganda reduced deforestation, adding to the debate on the use of monetary incentives in forest conservation.

Smallholder agricultural systems, strongly dependent on water resources and investments in shared infrastructure, make a significant contribution to food security in developing countries. These communities are being increasingly integrated into the global economy and are exposed to new global climate-related risks that may affect their willingness to cooperate in community-level collective action problems. We performed field experiments on public goods with private and collective risks in 118 small-scale rice-producing communities in four countries.

In the tropics, some agricultural lands are abandoned for economic or technical reasons, leading to the recovery of woody vegetation. Our research aimed to identify the main drivers of spontaneous recovery of vegetation in a basin located in the Colombian Andes. This was done by combining spatially explicit environmental and socioeconomic variables at landscape (e.g. distances to human settlements, to roads, and to forests and mean annual precipitation) and local scales (e.g. depth of the organic layer, soil bulk density, and canopy openness).

Small hydropower (SHP) has existed for more than a century in Colombia, and is gaining reserved interest as an option to mitigating climate change. In this paper we investigate the prospects for SHP in Colombia based on an analysis of economies-of-scale and learning-by-doing effects. We created an inventory of SHP plants realized in Colombia between 1900 and 2013, and focused on grid-connected SHP stations only. In the economies-of-scale part of our analysis we considered all SHP plants with a capacity lower than 20 MW.

Mining represents an important economic sector in almost all countries, especially the developing ones. The planning in this area is complex due to the interaction between different aspects like economic factors, environmental and social issues, and government regulation. A tool for policy analysis is needed to understand and test the effects of new and existing policies and avoid unanticipated side effects.

In this paper, we explore the synergies and tradeoffs between abatement of global and local pollution. We build a unique dataset of Swedish combined heat and power plants with detailed boiler-level data 2001–2009 on not only production and inputs but also on emissions of \hbox {CO}_{2} and \hbox {NO}_{\mathrm{x}}. Both pollutants are regulated by strict policies in Sweden. \hbox {CO}_{2} is subject to the European Union Emission Trading Scheme and Swedish carbon taxes; \hbox {NO}_{\mathrm{x}}—as a precursor of acid rain and eutrophication—is regulated by a heavy fee.
