Exploring Dual Discount Rates for Ecosystem Services: Evidence from a Marine Protected Area Network

Submitted by NENRE Concepcion on

This paper presents a joint estimation of willingness to pay for conservation activities aimed to preserve the flow of ecosystem services provided by a marine protected area network and respondents´ personal discount rate using a contingent valuation survey. It contributes to the literature on identifying people´s discount rates moving beyond the use of the exponential schemes, to include a hyperbolic discount rate through variations in the timing and duration of the provision of public goods.

Estimating the willingness to pay and the intertemporal discount rate for the protection of the biodiversity in the marine reserve, Choros-damas

Submitted by NENRE Concepcion on

In this paper we used a net present value model to jointly estimate the willingness to pay (WTP), and the intertemporal discount rate, for a biodiversity environmental conservation program whose payments are allocated along a time horizon. We applied a contingent valuation survey to capture the economic value associated with the protection of a marine ecosystem in the marine reserve, Choros-Damas in Chile. Respondents faced a scenario with a WTP question with periods of 1, 5, and 10 years.

What do respondents bring to contingent valuation? A comparison of monetary and labour payment vehicles

Submitted by Anonymous (not verified) on

In the contingent valuation method, both the goods being valued and the payment vehicles used to value them are mostly hypothetical. However, although numerous studies have examined the impact of experience with the good on the willingness to pay, less attention has been given to experience with the payment vehicles.

Labor as a Utility Measure in Contingent Valuation: Application to the Valuation of Restoration Projects in Latin America

Submitted by NENRE Concepcion on

Monetary contributions might not be an appropriate welfare measure in Contingent Valuation (CV) when household incomes are very low. In such cases, willingness to pay (WTP) is restricted by household's ability to reduce the consumption of other goods in order to pay for the environmental good under valuation. Beneficiaries, however, may be willing to contribute their time to work on the project instead of paying money.

Using stated preference methods to design cost-effective subsidy programs to induce technology adoption: An application to a stove program in southern Chile

Submitted by NENRE Concepcion on

We study the design of an economic incentive based program – a subsidy – to induce adoption of more efficient technology in a pollution reduction program in southern Chile. Stated preferences methods, contingent valuation (CV), and choice experiment (CE) are used to estimate the probability of adoption and the willingness to share the cost of a new technology by a household. The cost-effectiveness property of different subsidy schemes is explored numerically for different regulatory objectives.

Assessing the benefits and the costs of Dryland Forest in Central Chile

Submitted by NENRE Concepcion on

Investment in natural capital restoration is rapidly increasing as a response to the widespread ecological degradation of dryland areas in Latin America. Nonetheless, few attempts have been made to evaluate the costs and benefits of restoration initiatives in dryland ecosystems. By combining ecological and economic information, we assessed the benefits and costs of restoring ecosystem services in a dryland forest landscape in the Colliguay Valley, in central Chile. An active restoration program was evaluated by comparing its benefits and costs over a twenty five-year period.

Designing Contingent Valuation Scenarios for Environmental Health: the Case of Childhood Asthma

Submitted by NENRE Concepcion on

Objectives: We use a contingent valuation (CV) study of childhood asthma to discuss a central issue in designing CV studies of chronic illness—the need for a detailed, realistic scenario that minimizes confounding factors—and show how to address this issue. We apply our methodology to estimate households’ willingness to pay (WTP) for reductions in asthma morbidity.

The Natural Forest Protection Program in China: A contingent valuation study in Heilongjiang province

Submitted by admin on

In 1998 the Chinese government implemented the Natural Forest Protection Program, NFPP, which included logging restrictions, protected areas, replanting, and a range of other policies aimed at safeguarding the state of the country’s forests and reducing the risk of erosion and flooding.

The Valuation of Biodiversity Conservation by the South African Khomani San “Bushmen” Community

Submitted by admin on

The restitution of parkland to the Khomani San “bushmen” and Mier “agricultural” communities in May 2002 marked a significant shift in conservation in the Kgalagadi Transfrontier Park and environs in South Africa. Biodiversity conservation will benefit from this land restitution only if the Khomani San, who interact with nature more than do other groups, are good environmental stewards.
