Cost of Power Outages for Manufacturing Firms in Ethiopia: A Stated Preference Study

Having a reliable supply of electricity is essential for the operation of any firm. In most developing countries, however, electricity supply is highly unreliable. In this study, we estimate the cost of power outages for micro-, small-, and medium-sized enterprises in Addis Ababa, Ethiopia, using a stated preference survey. We find that the willingness to pay, and thus the cost of power outages, is substantial. The estimated willingness to pay for a reduction of one power outage corresponds to a tariff increase of 16 percent.


Fishing community preferences and willingness to pay for alternative developments of ecosystem-based fisheries management (EBFM) for Lake Naivasha, Kenya

Ecosystem-based fisheries management (EBFM) is an important complement to existing fisheries management approaches to maintain ecosystem health and function; to translate goals and aspirations for sustainability into operational objectives, the preferences of the fishing communities should be considered for successful implementation of EBFM. This study analysed the preferences of the fishing community for alternative EBFM developments for Lake Naivasha, Kenya, and estimated the willingness to pay, using a choice experiment approach.


Stakeholder perceptions of enhancement opportunities in the Chilean small and medium scale mussel aquaculture industry

The Chilean mussel aquaculture industry is a prime example of a thriving industry.  However, the industry growth rate, aquaculture concessions and market prices have stabilized signaling a shift in the industry from exponential growth to, if handled correctly, economic stability.  Here we used perception research, an efficient tool to inform on the implementation of management strategies, to provide policy makers with the tools necessary for the development of strategies that will aid in the sustainability of the industry through its current shift.  We assessed the perception


Functional forms and price elasticities in a discrete continuous choice model of the residential water demand

During recent decades, water demand estimation has gained considerable attention from scholars.  From an econometric perspective, the most used functional forms include log-log and linear specifications.  Despite the advances in this field and the relevance for policymaking, little attention has been paid to the functional forms used in these estimations, and most authors have not provided justifications for their selection of functional forms.  A discrete continuous choice model of the residential water demand is estimated using six functional forms (log-log, full-log, log q


Distributional impacts of climate change on basin communities: an integrated modeling approach.

Agriculture is one of the most vulnerable economic sectors to the impacts of climate change, specifically those related with expected changes in water availability.  By using a hydro-economic model, this study assesses the distributional impacts of climate change, considering the geographical location of each farmer’s community and the spatial allocation of water resources at basin scale.  A hydrological model, the Soil and Water Assessment Tool model, describes the basin hydrology, while farmers’ economic responses are represented using a non-linear agricultural supply model.&nbs


Valuing a water recreation facility using semi parametric estimators in the travel cost method

The goal of this research is to estimate, using semi parametric (SNP) techniques, the recreational benefits related to one strategic ecosystem of high moors in Colombia. This technique was used during the travel cost method estimation process due to its flexibility. The chosen SNP technique corresponded to the Fourier flexible form, adjusting a Poisson model, such that the truncation and endogenous stratification biases in the data base could be taken into account.
