Estimating Willingness-to-pay with Random Valuation Models


Book Description

Abstract: "This paper presents a case study of willingness-to-pay (WTP) estimation using random valuation models. A contingent valuation survey was conducted in Yerevan, Armenia to estimate people's WTP for the protection of Lake Sevan. Three elicitation formats - open-ended, closed-ended, and the stochastic payment card (SPC) approach - were used with split random samples. WTP models with heterogeneous errors were constructed and estimated with the survey data. The SPC approach produces a higher estimation of the mean WTP than both the open-ended and closed-ended approaches, while results from the open-ended and closed-ended elicitation formats are similar. Furthermore, contrary to research findings obtained in the United States, this study finds higher WTP estimations with mail surveys than with personal interviews. This paper - a product of the Infrastructure and Environment Team, Development Research Group is part of a larger effort in the group to understand the economics of sustainable development in developing countries"--World Bank web site.




Estimation of Willingness-to-Pay


Book Description

With the Price Estimation scene (PE scene) Christoph Breidert introduces a new method to estimate willingness-to-pay. It works as an additional interview scene appended to conjoint analysis and offers the respondents a dynamically generated sequence of product choices with assigned prices. The customers indicate whether they would actually purchase the presented product profiles.




Preference Data for Environmental Valuation


Book Description

The monetary valuation of environmental goods and services has evolved from a fringe field of study in the late 1970s and early 1980s to a primary focus of environmental economists over the past decade. Despite its rapid growth, practitioners of valuation techniques often find themselves defending their practices to both users of the results of applied studies and, perhaps more troubling, to other practitioners. One of the more heated threads of this internal debate over valuation techniques revolves around the types of data to use in performing a valuation study. In the infant years of the development of valuation techniques, two schools of thought emerged: the revealed preference school and the stated preference school, the latter of which is perhaps most associated with the contingent valuation method. In the midst of this debate an exciting new approach to non-market valuation was developed in the 1990s: a combination and joint estimation of revealed preference and stated preference data. There are two primary objectives for this book. One objective is to fill a gap in the nonmarket valuation "primer" literature. A number of books have appeared over the past decade that develop the theory and methods of nonmarket valuation but each takes an individual nonmarket valuation method approach. This book considers each of these valuation methods in combination with another method. These relationships can be exploited econometrically to obtain more valid and reliable estimates of willingness-to-pay relative to the individual methods. The second objective is to showcase recent and novel applications of data combination and joint estimation via a set of original, state-of-the-art studies that are contributed by leading researchers in the field. This book will be accessible to economists and consultants working in business or government, as well as an invaluable resource for researchers and students alike.




Valuing Environmental and Natural Resources


Book Description

Non-market valuation has become a broadly accepted and widely practiced means of measuring the economic values of the environment and natural resources. In this book, the authors provide a guide to the statistical and econometric practices that economists employ in estimating non-market values. The authors develop the econometric models that underlie the basic methods: contingent valuation, travel cost models, random utility models and hedonic models. They analyze the measurement of non-market values as a procedure with two steps: the estimation of parameters of demand and preference functions and the calculation of benefits from the estimated models. Each of the models is carefully developed from the preference function to the behavioral or response function that researchers observe. The models are then illustrated with datasets that characterize the kinds of data researchers typically deal with. The real world data and clarity of writing in this book will appeal to environmental economists, students, researchers and practitioners in multilateral banks and government agencies.




Marine Resource Damage Assessment


Book Description

The main focus of this important book is on civil liability regimes to compensate for ecological/environmental damage, the impact of EC decision-making on the international regime for oil pollution damage, the use of environmental funds in this respect, the economic valuation of damage to the environment from a theoretical perspective and the application of the Contingent Valuation Method in Belgium for ecological damage at sea.




Information and consumer willingness to pay for biofortified yellow cassava


Book Description

In this paper we use the Becker-deGroot-Marschak auction mechanism to estimate consumer demand for biofortified yellow cassava varieties in two states of Nigeria: Imo in the southeast and Oyo in the southwest. These two states exhibit distinct habitual product color preferences for staple food made with cassava. We estimate the effect of nutrition information campaigns and nature of planting material delivery institutions on consumer demand. Willingness to pay estimation accounted for the effect of product endowment censoring in bids and payment. Without a nutrition information campaign, biofortified varieties are unlikely to be accepted in the southeast as they are associated with substantial discounts. In the southwest, consumers are willing to pay a premium for light yellow biofortified cassava varieties even in the absence of nutrition information. The paper finds that nutrition information results in a large and significant price premium for biofortified yellow cassava in both states, but the nature of delivery institution has a small effect in the southwest only.




Valuing Ecosystem Services


Book Description

Nutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem servicesâ€"even intangible onesâ€"and calls for greater collaboration between ecologists and economists in such efforts.




A Primer on Nonmarket Valuation


Book Description

A Primer on Nonmarket Valuation is unique in its clear descriptions of the most commonly used nonmarket valuation techniques and their implementation. Individuals working for government agencies, attorneys involved with natural resource damage assessments, graduate students, and others will appreciate the non-technical and practical tone of this book. The first section of the book provides the context and theoretical foundation of nonmarket valuation, along with practical data issues. The middle two sections of the Primer describe the major stated and revealed nonmarket valuation techniques. For each technique, the steps involved in implementation are laid out and described. Both practitioners of nonmarket valuation and those who are new to the field will come away from these methods chapters with a thorough understanding of how to design, implement, and analyze a nonmarket valuation study. The concluding section takes stock of the usefulness of nonmarket valuation, highlighting chapters on benefit transfer, the role of nonmarket valuation in real decisions about natural resources, and where nonmarket valuation is headed in the future. As a companion to A Primer on Nonmarket Valuation, a website has been developed, http://www.fs.fed.us/nonmarketprimerdata/. This website includes downloadable datasets for each of the techniques described in the Primer, as well as links to published journal articles and reports based on the data. The website also provides an opportunity for students to estimate models using the data.
