Corporate social and environmental responsibility in services: Will consumers pay for it?

Two studies investigate consumer awareness of and response toward socially and environmentally responsible practices in the hospitality industry. Results suggest that consumers exhibit more positive response toward establishments exhibiting higher levels of social responsibility, although many are uninformed of the extent to which the organizations they patronize engage in such practices. Most consumers are willing to incur a modest price increase while patronizing an organization that behaves in an environmentally and socially responsible fashion, but that willingness declines dramatically as the price premium escalates. Consumers with high involvement in and positive attitudes toward corporate social responsibility practices are most willing to pay a premium.     

Strategy and response to purchase intention questions

Purchase intention and willingness-to-pay (WTP) questions are often analyzed without considering that a respondent's utility maximizing answer need not correspond to a truthful answer. In this paper, we argue that individuals act, at least partially, in their own self-interest when answering survey questions. Consumers are conceptualized as thinking along two strategic dimensions when asked hypothetical purchase intention and WTP questions: (a) whether their response will influence the future price of a product and (b) whether their response will influence whether a product will actually be offered. Results provide initial evidence that strategic behavior may exist for some goods and some people.     

Heterogeneity distributions of willingness-to-pay in choice models

We investigate direct and indirect specification of the distribution of consumer willingness-to-pay (WTP) for changes in product attributes in a choice setting. Typically, choice models identify WTP for an attribute as a ratio of the estimated attribute and price coefficients. Previous research in marketing and economics has discussed the problems with allowing for random coefficients on both attribute and price, especially when the distribution of the price coefficient has mass near zero. These problems can be avoided by combining a parameterization of the likelihood function that directly identifies WTP with a normal prior for WTP. We show that the typical likelihood parameterization in combination with what are regarded as standard heterogeneity distributions for attribute and price coefficients results in poorly behaved posterior WTP distributions, especially in small sample settings. The implied prior for WTP readily allows for substantial mass in the tails of the distribution and extreme individual-level estimates of WTP. We also demonstrate the sensitivity of profit maximizing prices to parameterization and priors for WTP.

Modification of Costanza's model of valuing ecosystem services and its application in China

In the past, evaluations of ecosystem functions were mostly based on Costanza's model, whereas the spatial, quality and temporal characteristics of regional ecosystems were not considered in the model.Focusing on these Issues, coefficients of regional difference, spatial heterogeneity and willingness-to-pay (WTP) were established to modify Costanza's model, and a new comprehensive valuation model of ecosystem functions is proposed.The analytical results indicate that the comprehensive model could evaluate regional ecosystem functions in China accurately and provide more helpful information for decision-making.The empirical study on Zhangbei County in Hebei Province shows that the intensive human activities could limit the provision of ecosystem functions while the planned ecological programs might promote the restoration of ecosystem functions.     

Economic valuation of environmental services sustained by water flows in the Yaqui River Delta

We attempted to estimate the economic value of environmental services provided by restored instream flows in the water-scarce Yaqui River Delta in Mexico. The Yaqui River begins near the U.S.-Mexico border and continues for 400 km before reaching the Oviachic dam, but has not reached the nearby Gulf of California for decades due to diversions for irrigation. These diversions have degraded the riparian ecosystem, coastal wetlands, and estuaries. Environmental services provided by restored flows in the Yaqui River would include healthy riverside vegetation, wetlands and estuaries, fish and wildlife habitats, non-use values, and recreation. A contingent valuation survey in 40 neighborhoods in the most populated Delta city, Ciudad Obregon, was administered to estimate non-market values of instream uses. Respondents were given a current and hypothetical Delta scenario (the latter assumed restored water flows in the River) and asked a willingness-to-pay (WTP) question regarding purchasing water for environmental flows through higher water bills. Results from 148 in-person interviews indicated that households would pay an average of 73 pesos monthly. WTP was found related to key variables suggested by economic theory and contingent valuation studies elsewhere: income, educational level, number of children in the household, and initial bid amount. These results will allow decision makers to compare the benefits generated by different water uses, including environmental services, and to manage scarce water resources under a long-term sustainable approach.     

Quality certification vs. product traceability: Consumer preferences for informational attributes of pork in Georgia

Consumer willingness-to-pay for informational attributes of food products is important information for food producers and supply chain participants and policy makers. We examine consumer demand in the pork sector of the Republic of Georgia. Results of conditional and mixed logit estimation, conducted on choice experiment data, reveal that Georgian consumers treat quality certification and product traceability attributes as substitutes. We also find that producers and other supply chain participants should be concerned primarily with maintaining the appearance of pork products. Retailer specific factors such as location and type of outlet can also substitute for product traceability. Store location and product appearance, however, are complementary attributes. In light of the recent turbulence in Georgia these consideration may be of paramount importance as participants in the supply chain seek to rebuild damaged infrastructure.     

Valuing environmental and health risk in agriculture: A choice experiment approach to pesticides in Italy

The widespread use of pesticides in agriculture shows a complex ramification of multiple negative externalities, ranging from food safety-related effects to the deterioration of farmland ecosystems. Recent research has demonstrated that the assessment of the economic implications of such negative processes is fraught with many uncertainties. This paper presents the results of an empirical study recently conducted in Northern Italy aimed at estimating the economic value of reducing the wide-ranging impacts of pesticide use, by deploying a Choice Experiment approach. The experimental design provides a meaningful tool to assign monetary values to the negative environmental effects associated with agrochemicals use. In this connection, the paper addresses in particular the reduction of farmland biodiversity, groundwater contamination and harm to human health. The resulting estimates confirm that, on average, respondents demonstrate a substantial willingness-to-pay a premium for agricultural goods (in particular, foodstuffs) produced in environmentally-benign ways.     

On the Edge of Buying: A Targeting Approach for Indecisive Buyers Based on Willingness-to-Pay Ranges

Targeting the “right” consumers is a core part of marketing. Whereas existing techniques to identify these consumers use demographic or psychographic variables or behaviors such as response probabilities, a proposed new targeting approach builds on consumers’ incremental responses to identify them by their willingness-to-pay (WTP) ranges. These WTP ranges reveal a consumer as a definite buyer, a definite non-buyer, or an indecisive buyer. The proposed theoretical framework indicates that indecisive buyers offer the highest incremental responses to targeted marketing mix activities and thus should be the most preferred targeting group. A sequence of three laboratory experimental studies validates the proposed approach for targeted price discounts and non-price tactics. In addition, a large-scale field experiment involving a consumer engagement campaign that includes observed purchase behavior demonstrates the high external validity and applicability of this approach.
