The Effect of Protest Votes on the Estimates of WTP for Use Values of Recreational Sites 总被引:1,自引:0,他引:1
Elisabetta Strazzera Margarita Genius Riccardo Scarpa George Hutchinson 《Environmental and Resource Economics》2003,25(4):461-476
Contingent valuation studies are often characterized by a considerable number of protest responses, which may cause selectivity bias on the final estimates for WTP. Sample selection models can detect and – if necessary – correct selectivity bias. In economic applications where the relevant dependent variable is continuous, sample selection models are generally estimated using Heckman's 2-step method rather than the FIML estimator. Either method has its own drawback: computational complexity for the FIML method, susceptibility to collinearity problems for the 2-step method. Using data on valuation of forest resources for recreational use, we analyse the performance of the two estimators. In this application, given the presence of some collinearity, the FIML is preferred to the 2-step method. A procedure is outlined to deal with selectivity problems in similar settings. 相似文献

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses. 相似文献

We critically review the literature that claims that existence values, or nonuse values in general, are a large and measurable component of total value for certain environmental resources. Our concern is not with the question “do nonuse values exist?” For some individuals they surely do. Rather, our concern is with two interrelated questions: are there operationally meaningful theorems which might lead to the specific measurement of nonuse values, and do we in fact have a body of credible evidence which shows that nonuse values, particularly components of any nonuse value, are “large”? We find nothing in the way of operationally meaningful hypotheses which would permit the estimation of values attributable to specific motives of individuals. We find no credible basis for claims related to either the measurement of existence and other motive-related values or claims for the “large” relative size of such values. In short, we question the conventional wisdom that such values are measurable and that they are significant as a component of total value. 相似文献

This paper explains the endowment effect, whereby sellers generally demand considerably more for a good than buyers are prepared to pay, and related anomalies. Many decisions, including nominating buying or selling prices, involve uncertainty, and we assert that people experience negative psychological reactions to uncertainty. These reactions can affect a person's valuation of the various options, biasing the person's actions towards the status quo, thus producing the endowment effect. Our model also proposes positive or negative reactions to unlikely prospects, which are able to explain commonly observed behaviour in the presence of ambiguity. 相似文献

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding
alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity
and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution
of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling
and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set
involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by
the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation
process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’
responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they
do not have a significant effect on welfare estimates.

In the context of testing the construct validity of stated preference studies, some researchers advocate the use of an “adding-up test” designed to gauge whether elicited values are sufficiently sensitive to a change in the scope (i.e. size) of a good. Crucial to the applicability of this test in practice, which relies on endowing a subsample of respondents with a good free of charge, is that the income effects due to endowment are negligible. In this study, we apply the adding-up test in an experimental value elicitation format to examine the potential effect of endowment as part of the test design on the adding-up property of elicited values. The results show that the adding-up property can be affected by free provision of part of the bundle. 相似文献

Regulatory moves towards reducing vehicle emissions have not proceeded with uniform success. Some regulations have been readily fulfilled, while others receive much criticism and resistance from the automotive industry. The reasons for this lie in matching the regulatory instrument with the technological capabilities of the auto industry. This paper develops a model describing the instruments used and their effectiveness in the US. In this case, low-emission vehicles which represent an incremental developmetn of established technologies are readily accepted by manufacturers and requre controlling instruments for their intorduction. However, zero-emission vehicles are outside the boundaries of traditional automotive firms, and their development has met more resistance and support for technology development has met more resistance and needs support for technology development as part of the regulations. 相似文献

FUND is an integrated assessment model of the interactions between climate and economy. Nine world regions emit greenhouse gases, and suffer damages from climate change. A number of greenhouse gas emission reduction policies are compared, including optimal and cost-effective strategies, strategies with early and late abatement, and strategies with and without international co-operation. The analyses confirm that co-operation matters, resulting in substantially lower costs or higher welfare. The real commitments of policy targets based on an absolute level (e.g., 1990 emissions) are hard to estimate because of the uncertainties in the baseline. Postponing action conflicts with minimising costs and maximising welfare, but so does sharp emission reduction at the short-term as proposed in the Kyoto Protocol. 相似文献

Recent empirical analyses show that asset flows can be modelled by the same 'gravity' equations that trade economists have used so successfully for the past few decades. This is something of a surprise. Trade economists do not yet have a unified theory of why gravity models should work‐and the situation is worse for asset flows. Reasonable theories would predict that greater distance between countries should generate more asset flows rather than less as the econometric results seem to consistently show. In this paper we discuss how host and source country GDPs, language, and distance the core explanatory variables in the traditional gravity models‐fare in trade and asset flows estimations. While the 'distance puzzle' is not resolved, it is considerably reduced by going beyond consideration of physical distance to concepts of transactional distance and scale economies. 相似文献

The Economic Value of Air-Pollution-Related Health Risks in China: A Contingent Valuation Study 总被引:2,自引:1,他引:2
The economic value of preventing adverse health effects related to air pollution is estimated using contingent valuation in
three diverse locations in China. Values are estimated for three health endpoints: cold, chronic bronchitis, and fatality.
Alternative statistical models are tested to study their impact on estimated willingness to pay (WTP) and on the relationship
between WTP and respondent characteristics. Using the official exchange rate, the sample-average median WTP to prevent an
episode of cold ranges between US$3 and US$6, the WTP to prevent a statistical case of chronic bronchitis ranges between US$500
and US$1,000, and the value per statistical life ranges between US$4,000 and US$17,000. Estimated mean values are between
two and thirteen times larger. Our estimates are between about 10 and 1,000 times smaller than estimates for the US and Taiwan
using official exchange rates. Indoor air quality, measured for a subset of respondents, shows no consistent relationship
with WTP. 相似文献

In this paper we analyse the role of financial resources in a process of competition interpreted as a continuous restructuring of productive capacities. Financial constraints appear an essential means of co-ordination. Co-ordination with the environment where this process of restructuring takes place for the process itself to be viable and co-ordination between firms for the survival of competition. 相似文献

Permanency and Flexibility of Institutions: The Role of Decentralization in Chinese Economic Reforms
The purpose of this paper is to offer a Lachmannian analysis aimed at studying the coherence and the efficiency of reforms in China in terms of institutional change. The idea is that transition dynamics cannot be analyzed by reference to market criteria only; transition is, above all, a change in institutions. Every transition economy thus faces the problem of creating a new institutional framework which associates the co-ordination of activities by the market with the preservation of a centralized mechanism of resource allocation. We explain that, in China, this role is played by decentralization. Indeed, we demonstrate that Chinese economic reforms, of which the main institutional vector is decentralization, show the particularity of reconciling, within one single logic, the permanency of a well-established institutional order required for the co-ordination of individual plans, and the flexibility of institutions necessary for the move towards the market. We then defend the theory that both the success and the originality of Chinese economic reforms rest on their capacity to resolve the permanency-flexibility dilemma. 相似文献

This study examines the linkages between environmental degradation (viewed primarily as deforestation and land degradation)
and the movement of population from one region to another within a developing country. The hypothesis postulated is that the
link between population and environmental degradation is mediated by the nature of property rights in land. This hypothesis
is examined with the help of two alternative methodologies. Firstly, a simultaneous equations model using data for the arid
and semi-arid region of Western India illustrates that outmigration from the region is largely the consequence of push factors
such as environmental degradation and decrease in common land. Alternatively, micro experiments in environmental protection
and the creation of common property rights on open access land in the same region indicate that the association between migrational
change, creation of common property rights and participation indices is high. It can be concluded that once property rights
are well defined with the help of appropriate institutional arrangements, labour moves towards the creation of common assets
and an improvement in the environment takes place. Out migration is prevented and higher levels of population are supported
by the same resources.

The Role of Political Instability in Stock Market Development and Economic Growth: The Case of Greece 总被引:1,自引:0,他引:1
This article examines empirically the relationship between stock market development, political instability and economic growth in Greece. We measure socio-political instability by constructing an index which captures the occurrence of various phenomena of political violence using time-series data. The main advantages of analysing political instability in a case study framework using time-series, in contrast with the widely used cross-country empirical studies, are: (a) a more careful and in-depth examination of institutional and historical characteristics of a particular country; (b) the use of a data set comprised of the most appropriate and highest quality measures; and (c) a more detailed exposition of the dynamic evolution of the economy. The empirical results indicate the existence of a strong negative relationship between uncertain socio-political conditions and the general index of the Athens Stock Exchange (ASE) and support the theoretical hypothesis that uncertain socio-political conditions affect economic growth negatively, is true for the Greek case.

This paper examines the relevance of Keynesian policies—interpreted as those policies implied by Keynes's theoretical analysis of unemployment developed in The General Theory—for a subset of developing economies, which are called semi-industrialized countries. It draws on recent contributions in development economics to argue on theoretical grounds that Keynesian policies are relevant for semi-industrialized countries even when they are constrained by capital shortages, stagnant agricultural sectors, and foreign exchange availability. It then discusses the recent development experience of India to illustrate the empirical relevance of some of these theoretical issues. 相似文献

The Wason card selection and the Tversky &; Kahneman frame anomaly are examined in the context of a probabilistic, constructivist biological model of decision-making. Rational choice requires that decision-makers understand the meaning of the choices they confront. In fact, the determination of meaning and the process of rational choice represent two sides the same coin. Further, perception, cognition and action are ill-posed problems. To solve these problems ‘missing data’ must be supplied by the brain. This data is acquired by both ontogenetic and phylogenetic processes. These evolutionary processes facilitate the determination of meaning and as a product of that process also facilitate the construction of rationality. Two interrelated brain systems involved in this construction process are examined: an emotional system that rapidly and non-consciously assigns reward expectancy values to objects in the environment and a sensory-motor system that participates in the discovery of more general information that facilitates environment/body interactions. Jointly, these systems help a naïve agent to find ‘meaning in an unlabeled world’ and to predict the outcomes of future interactions with that world by supplying ‘background’ information, i.e., by supplying the missing data necessary for rational choice. This ‘background’ represents the imprint of the statistical structure of the world on the brain and, as such, embodies the individual’s Bayesian priors. Lack of sufficient background capacities can result in systematic judgment errors and seemingly irrational decisions. Complex culture is a key aspect of the environment that facilitates the construction of rationality, in part, by becoming internalized as background. Culture facilitates the creation of complex social constructs that contribute to cultural evolution, reduce uncertainty, and increase rationality; however, cultural evolution can get ahead of itself—potentially leading to background failure and errors in judgment and choice. Finally, it is not simply complexity or lack of hands-on experience that lead to error: an additional component that might be called semantic opacity is necessary. 相似文献
