ABSTRACT Background and purpose: The purpose of this study is to fill the gap which is present in the science area of sustainable transport. According to the literature study that has been performed within this thesis it has not been possible to identify any studies which investigates what individuals that has a willingness to pay (WTP) for sustainable transport has in common. By investigating if there are any differences between these individuals the study aims to find a common ground in terms of socioeconomic factors or general attitude towards the climate. By doing this, the science gap within this area will be reduced and companies can use the result to identify which kind of services this should be applied to. If more companies apply the sustainable transport choice, more individuals will be able to choose it and the climate footprint could become smaller.    Method: In order to find differences between individuals it is essential to apply a method which can be established in the science. By performing a qualitative pre-study of earlier science and literature science, questions have been constructed to create a foundation for a survey. The survey was performed digitally and included questions about the individual socioeconomic factors, general attitude towards the climate and their WTP for sustainable transport. After removal of non-essential answers 109 respondents was left which became the foundation of the analysis. The study is limited to the author’s social network represented by people living in Sweden.   Result: The study has found common ground for individuals that has a WTP for sustainable transport. The socioeconomic differences of the individuals has no impact on their WTP for sustainable transport. An individual with WTP is known by its’ concern for the environment and by performing other climate smart choices in the everyday life.   Conclusion: The result support, which has been proven by this study, that all companies have the possibility to apply sustainable transport regardless of what target group they have. Also, companies that have individuals that do other climate smart choices as a target group has even bigger chances of successfully implementing sustainable transport.  Keywords: Sustainable transport, Green transport, Willingness to pay / SAMMANFATTNING Bakgrund och syfte: Syftet med denna studie är att fylla det gap som finns i forskningen inom området hållbar transport. Enligt den litteraturstudie som har utförts i anknytning till arbetet har det inte identifierats några studier som undersökt vad som kännetecknar individer som innehar betalningsvilja för hållbar transport. Genom att undersöka om det finns skillnader mellan individer och på så vis hitta gemensamma nämnare i form av socioekonomisk bakgrund eller generell inställning till miljön ska denna studie bidra till forskningen genom att dels täcka det gap som finns men också ge företag som kan applicera denna tjänst ett incitament för att ta det steget. Om fler företag erbjuder hållbar transport kommer fler individer ha möjlighet att välja denna tjänst och i sin tur kommer miljöpåverkan i samhället minska.   Metod: För att hitta skillnader mellan individer är det essentiellt att tillämpa ett metodval som kan förankras i forskningen. Genom en kvalitativ förstudie av tidigare forskning och litteratur har det utformats frågor som lagt grund för en enkätundersökning. Enkätundersökningen utfördes digitalt och inkluderade frågor om individens socioekonomiska bakgrund, generell inställning till miljön samt betalningsviljan för hållbar transport. Efter bortplockande av felaktigt genomförda undersökningar kvarstod 109 tillfrågade respondenter vilket la grund för den analys som sedan lett fram till resultatet. Studien är avgränsad till författarens sociala medier vilket är representerat av människor som bor i Sverige.   Resultat: Studien har hittat gemensamma nämnare för de individer som innehar en betalningsvilja för hållbar transport. Vad en individ har för socioekonomisk bakgrund spelar ingen roll för individens betalningsvilja för hållbar transport. En individ som innehar betalningsvilja för hållbar transport kännetecknas enbart av att den är orolig för klimatförändringarna och dess konsekvenser samt att den gör andra klimatsmarta val i vardagen.   Konklusion: Resultatet stödjer, med denna studie som grund, att hållbar transport kan appliceras på samtliga företag och det har alltså ingen betydelse vilken målgrupp produkten eller tjänsten inriktar sig på. Däremot har företag vars målgrupp är individer som gör andra klimatsmarta val ännu större chanser att lyckas sälja hållbar transport.   Nyckelord: Hållbar transport, Grön transport, Betalningsvilja

In this thesis we provide a theoretical framework for a dichotomous-choice contingent valuation survey for plastic and reusable shopping bags and consequential analysis of that data. By using interval regression analysis, a mean willingness to pay for continued use of plastic grocery bags and a mean willingness to accept to use reusable bags for all grocery shopping trips are estimated. The subsidy level was statistically robust while the tax level was not; this led us to the conclusion as cited from previous studies that people are very elastic to a plastic bag tax, and consequently a small tax provides tremendous consumptive declines.

Cluster thinning, leaf removal and kaolin application are three commonly employed means of modifying fruit zone microclimates assumed to improve grape and wine quality. High labour costs in addition to the potential for location and varietal-specific responses make the benefits of these practices equivocal. To explore this question, I employed a stratified random block design in two Vancouver Island commercial vineyards where Pinot gris vines were manipulated with one of four experimental treatments: control, cluster thinning to one cluster per shoot, heavy leaf removal with a Kaolin clay application, or a combined heavy leaf removal – cluster thinning - Kaolin treatment. The resulting wines were subjected to detailed sensory evaluations, consumer valuation, and a cost-benefit analysis to determine their respective return-on-investment. Results indicate that despite apparent sensory changes driven by vineyard treatments, the lack of any perceived added value suggests that regional producers of Pinot gris should avoid using the assessed treatments as strategies to increase wine quality. The cost-benefit analysis revealed that heavy leaf removal combined with Kaolin clay application may provide a benefit outside of changes to wine quality. The demonstrable improvement in growing conditions under this treatment resulted in a significant decrease in rot pressure. This suggests that the treatment may be a viable option for increasing usable yields of Pinot gris without placing an insurmountable financial cost on the producer. / Graduate

The objective of this study is to estimate the willingness to pay of U.S. Gulf Coast residents to support oyster reef restoration. The Gulf Coast is the leading commercial oyster- producing region in the United States, accounting for approximately 46% of the total commercial oyster harvest in 2021. My benefit estimates were based on data obtained from a contingent valuation survey of 6,475 Gulf Coast respondents. I estimated the willingness to pay (WTP) for oyster reef restoration using interval regression and Turnbull lower-bound methods. The estimated mean WTP value is in the range of $142 and $436 per household. The results show respondents who eat oysters and those that hold saltwater fishing licenses have significantly higher WTP.

The objective of this study was to estimate willingness-to-pay the population in Luleå is putting on the possibility to do recreation and outdoor life activities in an urban forest. The study has been limited to the area Ormberget-Herstölandet. A contingent valuation method has been applied which asks about willingness-to-pay to conserve current recreational activities by assuming other plans for the area. A total of 151 answers were received, of which 111 was used for the analysis. This study found that willingness-to-pay for recreation was estimated to be 173 SEK per person and as one-time-payment. Total estimated value for Luleå population was 13,500,000 SEK. Willingness-to-pay was positively influenced by the number of visits, time spent, income and preferences for cross-country skiing. Negatively influenced if the respondents are male and have high environmental concern.

Consumer demand for organic products has increased due to growing awareness of climate change and sustainability. However, the higher price of organic products is a barrier for some consumers. Previous research has examined various factors that influence consumers’ perceptions of organic products, but little attention has been paid to the influence of small firm cues. Understanding how small firm cues affect consumer behaviour could fill this gap and help small wineries overcome resistance to the price premium.  This study aims to investigate how the perception of small firm cues influences consumers’ willingness to pay for organic products, using organic wine as an example. Understanding this relationship can help small wineries market their products effectively and encourage them to switch to organic farming.  To fulfil the purpose of this thesis, a quantitative study was conducted. An online survey was developed with an experimental design to answer the research question empirically. Respondents were randomly assigned to either the control group or the experimental group. The experimental group was shown an organic wine label with a small firm cue and the control group with no cue.  The analyses showed that signalling a company’s small size did not affect consumers’ willingness to pay. Factors such as trustworthiness, perceived quality, and made with love did not affect the relationship between small firm cues and consumers’ willingness to pay. However, presenting a small firm cue resulted in increased consumer perceptions that the product is made with love. Nevertheless, this perception did not correspond to a higher willingness to pay.

This research focuses on estimating the shift in consumer willingness to pay (WTP) a price premium/discount for Native warm season grassed beef and for Bermuda grassed beef, an exotic species to the U.S. We utilized sensory analysis and the Becker-Degroot-Marschak (BDM) mechanism to elicit consumers’ preference for four different types of beef to determine how the premiums/discounts consumers place on these differentiated products change across information regimes: perception, experience, and complete information. Subjects participated in the BDM mechanism three times to determine their WTP: once after observing the raw packaged product with standard labeling information, once after a blind taste sample of the products, and once after complete information has been provided that links the raw packaged product to the blind taste sample. Results revealed strong preferences for NWSGed beef regardless of finishing methods, and positive impacts of the sensory results and label information on grassinished beef steaks.
