Eliciting Willingness to Pay without Bias using Follow-up Certainty Statements: Comparisons between Probably/Definitely and a 10-point Certainty Scale

Correction for hypothetical bias using follow up certainty questions often takes one of two forms: (1) two options, “definitely sure” and “probably sure”, or (2) a 10-point scale with 10 very certain. While both have been successful in eliminating hypothetical bias from estimates of WTP by calibrating based on the certainty of yes responses, little is known about the relationship between the two. The purpose of this paper is to compare the two using data from three field experiments in a private good, dichotomous choice format. We compare four types of yes responses that differ in the criterion used to determine if there is sufficient certainty for a hypothetical yes response to be considered a true yes response. We make several comparisons, but focus on determining which values on the 10-point scale give the same estimates of WTP as “definitely sure” hypothetical yeses and real yeses (actual purchases). Values that produce equivalence are near 10 on the certainty scale.     

Valuing climate protection through willingness to pay for biomass ethanol

This study uses a multi-part, split-sample contingent valuation method (CVM) and fair share (FS) survey to better understand the public's valuation of mitigating global climate change through its willingness to pay for biomass or “cellulosic” ethanol. In addition to a basic CVM question, a related scenario was developed that asked half of the survey respondents to state their fair share cost to lessen a potential food shortage in the next decade, also through the expanded use of cellulosic ethanol. Three alternative biomass feedstocks were assessed: farming residues, forestry residues and paper mill wastes, and municipal solid wastes. Overall a slightly larger proportion of respondents were WTP extra for cellulosic ethanol in the basic CVM scenario than in the FS scenario, though no significant differences were found in the WTP for the different feedstocks. Bid curve lognormal regression results for the two models were similar, supporting the idea that asking a FS rather than a conventional WTP question may be justifiable in some circumstances, such as in cases of a national emergency.     

Respondent uncertainty in a contingent market for carbon offsets

The main objective of this paper is to provide additional empirical evidence of what explains respondent uncertainty in contingent valuation (CV) and how this in turn affects stated willingness to pay (WTP). Air travelers asked to pay a carbon travel tax to offset carbon emissions from flying were asked how likely it is that they will actually pay if the tax is voluntary. When changing the market compliance imperative from a mandatory carbon tax to a voluntary contribution, a third of all air travelers consider it unlikely they will actually pay their stated WTP amount. An ordered probit estimation approach is applied to identify the sources of respondent uncertainty. Besides the bid price, respondent sense of responsibility and belief in the effectiveness of the voluntary carbon market are among the main reasons for the experienced uncertainty.

Money,Land or self-employment? Understanding preference heterogeneity in landowners’ choices for compensation under land acquisition in India

Land acquisition policies, upon which future land use patterns in India depend, are controversially tied to the question of whether to provide monetary or non-monetary compensation to affected landowners. However, turning to the preferences of landowners for answers only serves to complicate matters, as these are not homogenous on the question. This implies there is a need to identify the underlying factors giving rise to this preference heterogeneity, in order to develop more effective and efficient policy. This paper aims to address this gap using a contingent ranking experiment to study landowner disposition toward a range of compensation options, presented in a survey conducted in an ‘about-to-be-submerged’ region of a large, multi-stage irrigation project in India. Rankings were based on a selection of six compensation options, constituting different combinations of the attributes - cash, land, housing and self-employment. While the results suggest that landowners generally prefer non-monetary compensation, both the size of landholding and level of education of the landholder appear to influence the preferences for different compensation options. We find that landowners with more land or education tended to favour monetary compensation, while those with lower education or less land tended to favour housing and self-employment options. We close the text by exploring possible explanations for this specific form of heterogeneity, including access to information, to networks and capacities for income generation, and providing some reflections on the implications of these results for ensuring that rehabilitation and resettlement policies are both well targeted and effective.     

On financial guarantee insurance under stochastic interest rates

We extend the financial guarantee insurance literature by modeling, under stochastic interest rates, private financial guarantees when the guarantor potentially defaults. By performing numerical simulations under plausible parameters values, we characterize the differential impact of the incorporation of stochasticity of interest rates on the valuation of both public and private guarantees.     

The Development of an Instrument to Address the Negative Perception of Hospitality Jobs

ABSTRACT

The purpose of this study was to introduce a new construct that would assist in understanding employee attitudes and behaviors in hospitality sector jobs. The research introduces job-esteem and justifies it as a unique construct worthy of further study. Job-esteem is defined as the level of respect and dignity an individual believes is associated with his/her job. An instrument was developed to assist in measuring the level of job-esteem found in hospitality employees. The instrument was then administered to 75 employees of a large hotel chain in Hawaii. Tests show the instrument meets reliability standards.     

The moderating effect of self-esteem on consumer responses to global positioning in advertising

The study investigates consumers' responses to global positioning in advertising from the perspective of self. It is suggested that consumers' attitudes toward the brand advertised through global positioning are influenced by their ideal selves and cosmopolitan orientations and these influences are moderated by one's self-esteem level. Study 1 shows that attitudes toward the globally positioned brand are more positive for those with ideal selves that are more congruent with personal traits associated with globally positioned brands, but only for those with high self-esteem. Interview results from study 2 suggest that low self-esteem informants make use of the global brands associated with ‘Western’ as a means of signaling their social selves in order to obtain social approval and that high self-esteem informants attend to ad content, whether the ad employs global or local positioning.     

Close form pricing formulas for Coupon Cancellable CoCos

Contingent Convertibles (“CoCos”) are contingent capital instruments which convert into shares, or have a principal write down, if a trigger event takes place. CoCos exhibit the undesirable so-called death-spiral effect: by actively hedging the equity risk, investors can (unintentionally) force the conversion by making the share price deteriorate and eventually trigger the conversion.In this paper we introduce and analyse Coupon Cancellable CoCos (“CoCa CoCos”), a new type of CoCo where coupons can be cancelled during the lifetime of the note. We provide closed-form pricing formulas for CoCa CoCos, we study the impact of coupon cancellations in the price of the bond and we show that death-spiral effect is reduced.
