This paper presents the first value of statistical life (VSL) meta-analysis that empirically estimates correction factors
for ‘out of context’ benefits transfer (BT) purposes. In the field of mortality risk reductions elicited willingness to pay
values in one risk context, say road safety, are frequently applied in other risk contexts like air pollution. However, differences
in risk perception and the population at risk across contexts are likely to result in diverging VSL estimates. In a meta-analysis
of 26 international stated preference studies, a Bayesian model is estimated regressing contingent values for mortality risk
reductions, originating from three different risk contexts, on the characteristics of the risk reduction itself and additional
variables characterizing the underlying studies. A willingness to pay (WTP) premium for mortality risk reductions in the air
pollution and general mortality risk context relative to improving road safety is observed. Evaluated at the mean, road safety
VSL estimates should be multiplied by a factor 1.8 before being applicable in the air pollution context. Moreover, in an illustrative
BT exercise we find limited overlap in the set of context specific predictive VSL distributions. Consequently, ‘out of context’
BT results in a substantial over- or underestimation of the VSL. 相似文献

The main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments.
We test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice
experiment to report their experienced certainty when going through the choice tasks. In a split-sample test, we show that
follow-up choice certainty questions are procedural invariant. The self-reported certainty results indicate that learning
occurs, but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates
or variance across choice tasks. Additional tests of choice consistency suggest that preferences in the choice experiment
are stable and coherent. 相似文献

The local indivisibility of space complicates general equilibrium analysis. Mazzoleni and Montesano (1984, p. 286), suggest that the usual reasoning of the non-spatial analyses of competitive equilibrium can be performed in the context of a commodity space that contains subsets of land. This space, however, lacks a linear structure, so it resists application of the usual reasoning. Two examples will show that Mazzoleni and Montesano's existence results are flawed. 相似文献

This paper introduces to the field of marketing a regret-based discrete choice model for the analysis of multi-attribute consumer choices from multinomial choice sets. This random regret minimization (RRM) model, which has recently been introduced in the field of transport, forms a regret-based counterpart of the canonical random utility maximization (RUM) paradigm. This paper assesses empirical results based on 43 comparisons reported in peer-reviewed journal articles and book chapters, with the aim of finding out to what extent, when, and how RRM can form a viable addition to the consumer choice modeler's toolkit. The paper shows that RRM and hybrid RRM–RUM models outperform RUM counterparts in a majority of cases, in terms of model fit and predictive ability. Although differences in performance are quite small, the two paradigms often result in markedly different managerial implications due to considerable differences in, for example, market share forecasts. 相似文献

Although technical coefficients are estimated on the basis of flow data (use and make matrices), they are rarely treated as random variables. If this is done, an error term is added to the coefficients, rather than derived from the distribution of the data. Even so, the calculation of multipliers, by means of the Leontief inverse, is difficult. Due to the nonlinearity of this operation, the multiplier estimates are biased. By going back to the flow data, this paper provides unbiased and consistent employment and output multipliers estimates for the Andalusian economy. Rectangular use and make matrices are accommodated and problems associated with the construction and estimation of technical coefficients and the Leontief inverse are circumvented. 相似文献

In this paper we analyze the determinants of material inputs into individual production activities as a function of their outputs. We use observations on a large cross-section of U.S. manufacturing plants from the Census of Manufactures, including those that make goods primary to other industries, to study differences in production techniques. We find that in most cases material requirements do not depend on whether goods are made as primary products or as secondary products. We thus elucidate support for the commodity technology model as a useful working hypothesis. 相似文献

This study investigates the antecedents of franchisees’ assessments of franchisor trustworthiness. It combines multiple theoretical perspectives to develop a framework that is empirically tested with survey data from 128 franchisees of a Dutch franchise system. The results show that franchisees’ perceptions of a franchisor's fulfillment of its functional duties on proactive and reactive quality assurance and strategic management positively influence franchisees’ assessments of franchisor trustworthiness. Moreover, the results show that the impact of the antecedents on franchisees’ trustworthiness assessments varies across franchisees: market competition attenuates the influence of strategic management and reactive quality assurance. Unit performance does not moderate the importance of the antecedents. 相似文献
