A cost-benefit analysis of water quality protection in the Catawba basin
(Journal of the American Water Resources Association, 2002-01-01) Eisen-Hecht, JI; Kramer, RA
The primary objective of this study was to perform a cost-benefit analysis of maintaining the current level of water quality in the Catawba River basin. Economic benefits were estimated using a stated preference survey method designed to value respondents' willingness to pay for a management plan to protect water quality in the Catawba basin over time. From the surveys conducted with 1,085 area residents, we calculated an annual mean willingness to pay of $139 for the management plan, or more than $75.4 million for all taxpayers in the area. Over the five-year time horizon in which respondents were asked to pay for the management plan, this resulted in a total economic benefit of $340.1 million. The Watershed Analysis Risk Management Framework model was used to estimate the amount of management activities needed to protect the current level of water quality in the basin over time. Based on the model results, the total cost of the management plan was calculated to be $244.8 million over a ten-year period. The resulting cost-benefit analysis indicated that the potential benefits of this management plan would outweigh the costs by more than $95 million.

A policy simulation of the wetlands reserve program
(2017-11-30) Parks, PJ; Kramer, RA
Farmer participation in wetlands restoration practices is explained using land benefits, land attributes, and owner attributes. The probability of participation is estimated using county-level data, and used to calculate the expected acreage restored. National restored wetlands reserves are simulated by sorting counties on government cost and enrolling acreage into the reserve until the acreage target is reached. Total government cost for a million-acre reserve ranges from $1736 million to $1869 million, depending on the administrative strategy used. Using estimated participation rates in place of hypothetical rates suggests that achieving acreage targets may be more expensive than previously thought.

Ecosystem change and human health: implementation economics and policy.
(Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 2017-06) Pattanayak, SK; Kramer, RA; Vincent, JR
Several recent initiatives such as Planetary Health, EcoHealth and One Health claim that human health depends on flourishing natural ecosystems. However, little has been said about the operational and implementation challenges of health-oriented conservation actions on the ground. We contend that ecological-epidemiological research must be complemented by a form of implementation science that examines: (i) the links between specific conservation actions and the resulting ecological changes, and (ii) how this ecological change impacts human health and well-being, when human behaviours are considered. Drawing on the policy evaluation tradition in public economics, first, we present three examples of recent social science research on conservation interventions that affect human health. These examples are from low- and middle-income countries in the tropics and subtropics. Second, drawing on these examples, we present three propositions related to impact evaluation and non-market valuation that can help guide future multidisciplinary research on conservation and human health. Research guided by these propositions will allow stakeholders to determine how ecosystem-mediated strategies for health promotion compare with more conventional biomedical prevention and treatment strategies for safeguarding health.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'.

Estimating the economic value of water quality protection in the Catawba River basin
(Water Resources Research, 2002-09-01) Kramer, RA; Eisen-Hecht, JI
[1] This study used stated preference methods to estimate the economic value of protecting water quality in the Catawba River basin of North and South Carolina at its current level. Telephone interviews were completed with 1085 randomly selected households, who were also mailed a short information booklet about these issues. Respondents expressed a mean willingness to pay $139 for a management plan designed to protect water quality at its current level over time. Aggregation of this mean willingness to pay value amounted to an annual economic benefit of over $75 million for all taxpayers in Catawba basin counties. By using a split-sample survey design, this study also compared the effectiveness of different combined mail and telephone survey formats. Results indicated that while a phone-mail-phone approach is preferred for some reasons over a mail-phone approach, the survey format did not significantly affect the economic valuation results.

Factors influencing malaria control policy-making in Kenya, Uganda and Tanzania.
(Malar J, 2014-08-08) Mutero, CM; Kramer, RA; Paul, C.; Lesser, A; Miranda, ML; Mboera, LEG; Kiptui, R; Kabatereine, N; Ameneshewa, B
BACKGROUND: Policy decisions for malaria control are often difficult to make as decision-makers have to carefully consider an array of options and respond to the needs of a large number of stakeholders. This study assessed the factors and specific objectives that influence malaria control policy decisions, as a crucial first step towards developing an inclusive malaria decision analysis support tool (MDAST). METHODS: Country-specific stakeholder engagement activities using structured questionnaires were carried out in Kenya, Uganda and Tanzania. The survey respondents were drawn from a non-random purposeful sample of stakeholders, targeting individuals in ministries and non-governmental organizations whose policy decisions and actions are likely to have an impact on the status of malaria. Summary statistics across the three countries are presented in aggregate. RESULTS: Important findings aggregated across countries included a belief that donor preferences and agendas were exerting too much influence on malaria policies in the countries. Respondents on average also thought that some relevant objectives such as engaging members of parliament by the agency responsible for malaria control in a particular country were not being given enough consideration in malaria decision-making. Factors found to influence decisions regarding specific malaria control strategies included donor agendas, costs, effectiveness of interventions, health and environmental impacts, compliance and/acceptance, financial sustainability, and vector resistance to insecticides. CONCLUSION: Malaria control decision-makers in Kenya, Uganda and Tanzania take into account health and environmental impacts as well as cost implications of different intervention strategies. Further engagement of government legislators and other policy makers is needed in order to increase funding from domestic sources, reduce donor dependence, sustain interventions and consolidate current gains in malaria.

Open access in a spatially delineated artisanal fishery: The case of Minahasa, Indonesia
(Environment and Development Economics, 2007-02-01) Liese, C; Smith, MD; Kramer, RA
The effects of economic development on the exploitation of renewable resources are investigated in settings where property rights are ill defined or not enforced. This paper explores potential conservation implications from labor and product market developments, such as enhanced transportation infrastructure. A model is developed that predicts individual fish catch per unit effort based on characteristics of individual fishermen and the development status of their villages. The econometric model is estimated using data from a cross-sectional household survey of artisanal coral reef fishermen in Minahasa, Indonesia, taking account of fishermen heterogeneity. Variation across different villages and across fishermen within the villages is used to explore the effects of development. Strong evidence is found for the countervailing forces of product and labor market effects on the exploitation of a coral reef fishery. © 2007 Cambridge University Press.

Preference Heterogeneity in the Structural Estimation of Efficient Pigovian Incentives for Insecticide Spraying to Reduce Malaria
(Environmental and Resource Economics, 2017-01-18) Brown, ZS; Kramer, RA
This paper bridges the theoretical and empirical literatures on the role of preference heterogeneity in characterizing externalities related to disease transmission. We use a theoretical structure similar to locational sorting models, which characterize equilibria in terms of marginal individuals who are indifferent between locations. In our case, the ‘locations’ are binary, consisting of whether or not to take a discrete preventative action. Individual heterogeneity arises in this structure due to variation in the costs and disutility associated with prevention. We demonstrate application of this approach in the context of participation in insecticide-based indoor residual spraying programs for malaria control in northern Uganda. We identify the parameters of our theoretical model using a stated preference choice experiment combined with estimates from published epidemiological studies. The model implies that Pigovian subsidies for participation in this context should decrease household malaria risk by 19–25%. Our approach can be applied to other bioeconomic externalities with spillovers from discrete preventative actions, including agricultural pest management and the control of pest infestations and invasive species.

Seeing the forest for the fuel
(Environment and Development Economics, 2004-02-01) Pattanayak, SK; Sills, EO; Kramer, RA
We demonstrate a new approach to understanding the role of fuelwood in the rural household economy by applying insights from travel cost modeling to author-compiled household survey data and meso-scale environmental statistics from Ruteng Park in Flores, Indonesia. We characterize Manggarai farming households' fuelwood collection trips as inputs into household production of the utility yielding service of cooking and heating. The number of trips taken by households depends on the shadow price of fuelwood collection or the travel cost, which is endogenous. Econometric analyses using truncated negative binomial regression models and correcting for endogeneity show that the Manggarai are 'economically rational' about fuelwood collection and access to the forests for fuelwood makes substantial contributions to household welfare. Increasing cost of forest access, wealth, use of alternative fuels, ownership of kerosene stoves, trees on farm, park staff activity, primary schools and roads, and overall development could all reduce dependence on collecting fuelwood from forests. © 2004 Cambridge University Press.

Spatial patterns of market participation and resource extraction: Fuelwood collection in Northern Uganda
(American Journal of Agricultural Economics, 2017-07-01) Miteva, DA; Kramer, RA; Brown, ZS; Smith, MD
While distance to markets is a key determinant of market participation for households that are dependent on natural resources, the distance to the resource stock is also essential. Thus, a household's location with respect to markets and the resource stock determines household market participation and associated resource degradation. Applying a discrete-choice framework for fuelwood collection in a developing country, we characterize the spatial pattern of market participation regimes and forest use. All else being equal, autarkic households are closest to the forest and furthest from the market, buyer households are closest to the market and furthest from the forest, and seller households are at intermediate distances. Empirical tests based on survey data from northern Uganda support the predictions from our theoretical model. Our findings have important implications for understanding the spatial patterns of forest degradation and determining the control group when designing impact evaluations of the effectiveness of development and conservation interventions.

Valuing a global environmental good: U.S. residents’ willingness to pay to protect tropical rain forests
(2018-01-01) Kramer, RA; Mercer, DE
Although contingent valuation (CV) is the most common technique for valuing nonmarket environmental resources, rarely has it been applied to global environmental goods. This study uses CV in a national survey to assess the value U.S. residents place on tropical rain forest protection. On average, respondents were willing to make a onetime payment of approximately $21-31 per household to protect an additional 5 percent of tropical forests. Although respondents were able to give consistent responses across two different CV formats, focus groups were unwilling or unable to allocate their aggregate rainforest valuations across or among regions or specific rain forests.

Valuing drinking water provision as an ecosystem service in the neuse river basin
(Journal of Water Resources Planning and Management, 2010-07-01) Elsin, YK; Kramer, RA; Jenkins, WA
The valuation of ecosystem services such as drinking water provision is of growing national and international interest. The cost of drinking water provision is directly linked to the quality of its raw water input, which is itself affected by upstream land use patterns. This analysis employs the benefit transfer method to quantify the economic benefits of water quality improvements for drinking water production in the Neuse River Basin in North Carolina. Two benefit transfer approaches, value transfer and function transfer, are implemented by combining the results of four previously published studies with data collected from eight Neuse Basin water treatment plants. The mean net present value of the cost reduction estimates for the entire Neuse Basin ranged from $2.7 million to $16.6 million for a 30% improvement in water quality over a 30-year period. The value-transfer approach tended to produce larger expected benefits than the function-transfer approach, but both approaches produced similar results despite the differences in their methodologies, time frames, study sites, and assumptions. © 2010 ASCE.

Valuing ecosystem services from wetlands restoration in the Mississippi Alluvial Valley
(Ecological Economics, 2010-03-15) Jenkins, WA; Murray, BC; Kramer, RA; Faulkner, SP
This study assesses the value of restoring forested wetlands via the U.S. government's Wetlands Reserve Program (WRP) in the Mississippi Alluvial Valley by quantifying and monetizing ecosystem services. The three focal services are greenhouse gas (GHG) mitigation, nitrogen mitigation, and waterfowl recreation. Site- and region-level measurements of these ecosystem services are combined with process models to quantify their production on agricultural land, which serves as the baseline, and on restored wetlands. We adjust and transform these measures into per-hectare, valuation-ready units and monetize them with prices from emerging ecosystem markets and the environmental economics literature. By valuing three of the many ecosystem services produced, we generate lower bound estimates for the total ecosystem value of the wetlands restoration. Social welfare value is found to be between $1435 and $1486/ha/year, with GHG mitigation valued in the range of $171 to $222, nitrogen mitigation at $1248, and waterfowl recreation at $16. Limited to existing markets, the estimate for annual market value is merely $70/ha, but when fully accounting for potential markets, this estimate rises to $1035/ha. The estimated social value surpasses the public expenditure or social cost of wetlands restoration in only 1 year, indicating that the return on public investment is very attractive for the WRP. Moreover, the potential market value is substantially greater than landowner opportunity costs, showing that payments to private landowners to restore wetlands could also be profitable for individual landowners. © 2009 Elsevier B.V.

Worth of watersheds: A producer surplus approach for valuing drought mitigation in Eastern Indonesia
(Environment and Development Economics, 2001-02-01) Pattanayak, SK; Kramer, RA
This study combines hydrological modeling with applied micro-econometric techniques to value a complex ecosystem service: drought mitigation provided by tropical forested watersheds to agrarian communities. Spatial variation in current base-flow allows estimation of drought mitigation values as the marginal profit accruing to agricultural households. The paper shows that this uncommon focus on producer (not consumer) surplus measures is appropriate for valuation as long as markets for commodities related to the environmental services are complete. For the typical household, the estimated marginal profit is positive, validating the central hypothesis that baseflow makes positive contributions to agricultural profits. There is some evidence, however, that increased watershed protection will increase profits through greater baseflow only in watersheds with a unique mix of physio-graphic and climatic features. The paper evaluates and provides some support for the hypothesis, put forward by hydrological science and the Indonesian Government, that protected watersheds can supply latent and unrecognized ecosystem services to local people.
