Valoração Econômica do Engenho Central de Piracicaba (SP) AgEcon
Joao, Livia Salla; Lima, Roberto Arruda de Souza.
Este artigo apresenta a estimativa do valor econômico do Engenho Central de Piracicaba (SP). Trata-se de um conjunto fabril fundado em 1881, desativado em 1974 e reconhecido como patrimônio histórico, sendo posteriormente desapropriado pela Prefeitura e transformado em importante espaço cultural, artístico e recreativo. Para mensurar os valores de uso, de opção e de existência desta obra, foi escolhido o método da valoração contingente. Este método é uma das abordagens mais utilizadas para valoração de bens com características de não-exclusividade e não-rivalidade. Obteve-se disposição a pagar (DAP) nula, isto é, o valor atribuído ao Engenho Central pela população de Piracicaba foi nulo.-----------------------------------------This article presents an...

DEMAND FOR RAINFALL-INDEX BASED INSURANCE: A CASE STUDY FROM MOROCCO AgEcon
McCarthy, Nancy.
In this paper, we derive estimates for willingness to pay for rainfall-index based insurance contracts. Surveys were undertaken in four regions in Morocco, representing different mean and variability of rainfall conditions. Results indicate that respondents in the high variability regions preferred contracts that paid out more often (had higher rainfall trigger levels), and which were more costly. In fact, a strong majority of respondents indicated they would purchase these contracts at the fair-value price; the estimated median willingness to pay for such contracts was between 12-20 percent above the fair value contract. However, in the lower rainfall variability regions, the cheaper contracts with lower trigger values were the only contracts for which...

Comparing the Conventional Stated Preference Valuation Technique with a Prediction Approach. AgEcon
Yadav, Lava; van Rensburg, Tom M.; Kelley, Hugh.
Stated preference techniques have been used to place values on public goods by directly asking individuals to provide their personal values and opinions. This method has consistently resulted in the emergence of hypothetical bias. Several insights from the psychology literature suggest that social desirability bias, a contributor to hypothetical bias, occurs when individuals face such direct questions. However, replacing the direct questions with an indirect one that asks for their predictions about other’s values can potentially eliminate this bias. In this study we employ both questioning formats in a choice experiment to make comparisons between the stated responses. Predicted willingness to pay is 2.5 and 3.1 times smaller than hypothetical values...

Households’ WTP for the Reliability of Gas Supply AgEcon
Chou, Wan-Jung; Bigano, Andrea; Hunt, Alistair; La Branche, Stephane; Markandya, Anil; Pierfederici, Roberta.
The security of natural gas supply is an important issue for all EU countries due to the region’s heavy dependence on imported supply sources and in light of energy demand for gas that is continuously increasing. Discussions have emphasised strategies for securing the supply at the macro level, e.g. diversification in supply sources, increase in storage capacity, etc. By contrast, consumers’ demand for the reliability of gas supply is rarely investigated. Hence this study was conducted to examine the economic implications associated with the security of gas supply directly to domestic consumers. Based on the choice experiment approach, household surveys were conducted in France, Italy and the UK. The results confirmed that the degree of the economic impact...

Emerging Markets for GM Foods: A Study of Consumer's Willingness to Pay in India AgEcon
Deodhar, Satish Y.; Ganesh, Sankar; Chern, Wen S..
A random utility approach is used to estimate logit equations which indicate what factors affect the likelihood of consumption of non-GM and GM foods, and, whether or not consumers are willing to pay a premium for non-GM/GM foods. Ceteris paribus as the price difference between non-GM and GM food rose, people were more likely to consume GM foods. Likelihood of GM food consumption was higher in the middle income brackets. Consumers were willing to pay an expected premium of 19.5% and 16.12% for golden rice and GM edible oil respectively. In case of chicken, consumers seemed to pay a very negligible premium for non-GM fed chicken. Overall, it appears that GM foods may be acceptable in the Indian market. However, basic awareness about the GM foods may...

The Influence of Endogenous Nutrition Knowledge on Consumers’ Willingness-To-Pay for Grass-Fed Beef AgEcon
Xue, Hong; Mainville, Denise Y.; You, Wen; Nayga, Rodolfo M., Jr..
The relationship between nutrition knowledge and consumers’ food behavior has been debated for years. This may be partially attributed to the difficulty introduce by endogeneity of nutrition knowledge in econometric modeling. Using grass-fed beef as a vehicle, this paper investigates the impacts of consumers’ nutrition knowledge on their willingness to pay by accommodating the endogeneity problem using instrumental variable approach. Our results suggest that consumers’ nutrition knowledge significantly influences their willingness to pay for grass-fed beef. Gender and education are influential factors of consumers’ nutrition knowledge level.

Empirical Evidence Showing The Relationships Between Three Approaches For Pollution Control AgEcon
Wilson, Clevo.
Willingness to pay models have shown the theoretical relationships between the contingent valuation, cost of illness and the avertive behaviour approaches. In this paper, field survey data are used to compare the relationships between these three approaches and to demonstrate that contingent valuation bids exceed the sum of cost of illness and the avertive behaviour approach estimates. The estimates provide a validity check for CV bids and further support the claim that contingent valuation studies are theoretically consistent.

Media Advertising and Ballot Initiatives: An Experimental Analysis AgEcon
Allender, William J.; Richards, Timothy J.; Fang, Di; Doyon, Maurice.
Spending on political advertising increases with every election cycle, not only for congressional or presidential candidates, but also for state-level ballot initiatives. There is little research in marketing, however, on the effectiveness of political advertising at this level. In this study, we conduct an experimental analysis of advertisements used during the 2008 campaign to mandate new animal welfare standards in California (Proposition 2). Using subjects' willingness to pay for cage-free eggs as a proxy for their likely voting behavior, we investigate whether advertising provides real information to likely voters, and thus sharpens their existing attitudes toward the issue, or whether advertising can indeed change preferences. We find that...

Consumer Willingness to Pay for Irradiated Beef AgEcon
Nayga, Rodolfo M., Jr.; Poghosyan, Arsen; Nichols, John P..
This study examines consumer willingness to pay for irradiated beef products. About 58 percent of the respondents are willing to pay a premium for irradiated beef. An ordered probit with sample selection model was estimated. Standard errors of the marginal effects of the ordered probit model were estimated using the bootstrap method. Our findings suggest that females and those who think that improper handling contributes to food poisoning are more likely to pay a premium of 50 cents per pound of irradiated beef than others. Those who trust the irradiation technology are also more likely to pay a premium of between 5 to 25 cents per pound for irradiated beef. Supply chain implications are discussed.

Consumer WTP for Blueberry Attributes: A Hierarchical Bayesian Approach in the WTP Space AgEcon
Shi, Lijia; House, Lisa; Gao, Zhifeng.
A stated preference experiment is conducted to elicit consumer WTPs for various blueberry attributes. The mixed logit model is employed to account for consumer heterogeneity. The model is set up in the WTP space where the distributions of WTPs are directly specified. Considering the high diversity of consumer perception and the remarkable benefits from differential marketing, we apply the hierarchical Bayesian approach and the discussion is based on the individual level WTP estimates. The results show that “local produced” attribute is preferred over simply “produced in the U.S.” by most respondents. By contrast, less than 50% of the respondents are willing to pay premium for organic blueberries. In addition, hardly any relationship between demographics...

Assessing Consumer Willingness to Pay a Premium for Organic Food Product: Evidence from Ghana AgEcon
Owusu, Victor.
This paper examines the willingness of consumers to pay a premium for organic food product with a contingent valuation data from urban Kumasi of Ghana. Consumer’s willingness to pay a premium is estimated with a bivariate Tobit model. The empirical findings indicate that apart from socioeconomic characteristics and consumer perceptions, product attributes tend to influence consumer preferences for organic water melon and lettuce. The estimated mean WTP premium for 1 kilogram of water melon is GH¢0.5554 (US$ 0.4575) and that of organic lettuce is GH¢1.2579 (US$1.0361).

Characterizing Spatial Pattern in Ecosystem Service Values when Distance Decay Doesn’t Apply: Choice Experiments and Local Indicators of Spatial Association AgEcon
Johnston, Robert J.; Ramachandran, Mahesh; Schultz, Eric T.; Segerson, Kathleen; Besedin, Elena Y..
Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly abandoned by non-economics disciplines in favor of approaches that allow for spatial patchiness. This paper develops parallel methods to evaluate local patchiness and hot spots in stated preference welfare estimates, characterizing relevant patterns overlooked by traditional approaches. The analysis draws from a choice experiment addressing river restoration. Results demonstrate shortcomings in standard treatments of spatial heterogeneity and insights available...

Modeling Certainty-Adjusted Willingness to Pay for Ecosystem Service Improvement from Agriculture AgEcon
Ma, Shan; Lupi, Frank; Swinton, Scott M.; Chen, Huilan.
The public demand for ecosystem services measured by willingness to pay (WTP) in contingent valuation studies provides important information for designing Payment-for-Ecosystem-Service (PES) programs. However, the hypothetical markets for contingent valuation and respondents’ unfamiliarity with certain ecosystem services may increase their preference uncertainty, which may increase variance and even cause bias in WTP estimates. Taking advantage of a unique stated preference data set that includes a follow-up question rating the respondent’s certainty level, this study evaluates alternative methods of modeling certainty-adjusted WTP for cleaner lakes and abated global warming. Results suggest that the incorporation of self-reported uncertainty into binary...

Valuing Farmland Protection with Choice Experiments That Incorporate Preference Heterogeneity: Does Policy Guidance Depend On the Econometric Fine Print? AgEcon
Johnston, Robert J.; Bergstrom, John C..
Although mixed logit models are common in stated preference applications, resulting welfare estimates can be sensitive to minor changes in specification. This can be of critical relevance for policy and welfare analysis, particularly if policymakers are unaware of practical implications. Drawing from an application to agricultural conservation in Georgia, this paper quantifies the sensitivity of welfare estimates to common variations in mixed logit specification and assesses practical implications for policy guidance. Results suggest that practitioners may wish to reevaluate modeling and reporting procedures to reflect the welfare and policy implications of common but often unnoticed variations in model specification.

Measuring Market Potential for Fresh Organic Fruit and Vegetable in Ghana AgEcon
Owusu, Victor; Owusu, Michael Anifori.
This paper examines the market potential for fresh organic lettuce and water melon with a recently collected data on consumers from Kumasi metropolis of Ghana. Using a doublebounded dichotomous choice contingent valuation technique, consumer’s willingness to pay is estimated with a Tobit model to address the zero willingness to pay responses in the sample data. As much as 71% of the consumers are willing to pay over 50% price premiums for organic vegetables and over 82% are willing to pay 1%–50% price premiums for organic fruits. The empirical results indicate that human capital, product attributes and consumer perception influence consumers’ willing to pay for organic food products. The estimated market potential for organic fruit is GH¢32,117,113 (US$...

Willingness to Pay for Traceable Meat Attributes: A Meta-analysis AgEcon
Cicia, Gianni; Colantuoni, Francesca.
Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a great deal of information in this regard, although specific to the conditions of each study. In light of this, WTP estimates for traceability characteristics differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta-analysis allows us to analyze consistency across studies and control for factors thought to drive variations in WTP estimates. The meta-analysis has been conducted using 23 studies that, in aggregate, report 88 valuations for WTP. Our results, aside from releasing unconditional information on the WTP for...

Risk Belief, Producer Demand, and Valuation of Improved Irrigations: Results from Field Experiments in Mt. Kilimanjaro AgEcon
Muamba, Francis; Kraybill, David S..
This paper systematically estimates the potential benefit of introducing improved irrigation schemes in Mt. Kilimanjaro to help rain dependent farmers cope with the risks of climate change. The study uses Contingent Valuation Method (CVM) to elicit farmers’ Willingness to Pay (WTP) for eliminating the risks of crop loss by accessing improved irrigation schemes. Data for the analysis were gathered using a double bounded survey from over 200 randomly-sampled farmers in 15 villages. The study makes a contribution to the applied welfare literature and should also be useful for policymakers in Africa. The policy contribution consists of valuation of improved irrigation in the presence of climate change risks. The applied welfare contribution consists of...
