Vad kan konsumenter och vad litar de på? : en studie kring sambandet mellan konsumenters kunskap och förtroende gentemot kommunikationen av miljövänliga textila produkter / What do consumers know and what do they trust? : a study on the relationship between consumers’ knowledge and trust towards the communication of environmentally friendly textile products

Strömberg, Rebecca, Svensson, Lina January 2015 (has links)
Syfte – I denna studie undersöks sambandet mellan konsumenters kunskap och förtroendegentemot kommunikationen av miljövänliga textila produkter.Teoretiskt ramverk – För att undersöka syftet redogörs vad kunskap respektive förtroendeär. Det teoretiska ramverket stod även till grund för utformandet av metoden, och av denanledningen redogörs i detta kapitel hur kunskap respektive förtroende kan mätas.Metod – Studien grundades på en enkätundersökning där respondenternas kunskap ochförtroende för miljövänlig textil produktion prövades. Resultatet analyserades sedan medchi2-test för att statistiskt säkerställa eller förkasta samband mellan kunskapsnivå ochförtroendenivå.Resultat och analys – Resultatet visade inte något statistiskt samband mellanrespondenternas kunskaps- och förtroendenivå. Studien visade även att respondenternaskunskapsnivå var generellt sett låg, utifrån det kunskapstest som gjordes ienkätundersökningen. Respondenternas förtroendenivå gentemot textila produkter somkommuniceras med miljömärkningar var högre än för de textila produkter som kommunicerassom miljövänliga utan användning av miljömärkningar.Diskussion och slutsats – Den låga kunskapen om kommunikationen av miljövänliga textilaprodukter kan bero på att konsumenter inte blir tillräckligt exponerade med information kringämnet, men kan även bero på bristande intresse och tid hos konsumenten. Det låga förtroendetför textila produkter utan miljömärkningar kan bero på att respondenterna varit med omgreenwashing. Att förtroendet är högre för produkter som marknadsförs med miljömärkningarkan bero på att dessa organisationer har en högre auktoritet och att konsumenter litar på attcertifieringarna ser till att produkter uppfyller vissa kriterier.Fortsatt forskning – En mer omfattande studie inom samma område med ett större antalrespondenter hade varit intressant, för att undersöka om detta skulle kunna påverka chi2-testen. En annan intressant aspekt att gå djupare in på är varför kunskapen respektiveförtroende ligger på de nivåer de gör och vad företag och organisationer skulle kunna göra föratt förändra dessa. / Purpose – The aim of this paper is to examine the relationship between consumers’knowledge and trust towards the communication of environmentally friendly textile products.Theoretical Framework - To examine the purpose of this study, the terms knowledge andtrust needed clarification. The theoretical framework was also the foundation for the design ofthe method, and therefore this chapter clarifies how consumers’ knowledge and trust can bemeasured.Method – The study was based on a survey in which respondents' knowledge and trusttowards eco-friendly textile production was measured. The results were then analysed withchi2-tests to statistically ensure or reject correlations between the levels of knowledge andtrust.Results and Analysis – The result from the chi2-tests did not show any statistical correlationbetween the respondents' knowledge and trust levels. The results of the survey showed thatthe respondents' level of knowledge towards the communication of environmentally friendlytextile products was generally low. The respondents' levels of trust towards textile productscommunicated with eco-labels were higher than for those textile products that arecommunicated as environmentally friendly without the use of eco-labels.Discussion and Conclusion – The low knowledge of communication of eco-friendly textileproducts can be caused by consumers’ lack of time and interest or because consumers are notsufficiently exposed to information about the subject. The low trust in textile products withouteco-labels may be caused by greenwashing. Consumers may also have a higher trust towardseco-labels because these organizations have a higher authority and because consumers maytrust that certifications ensure that products fulfils certain criteria.Continued Research – A more extensive study in the same field with a larger number ofrespondents would be interesting to investigate, whether this might affect the chi2-tests.Another interesting aspect to study is the reasons behind the consumers’ levels of knowledgeand trust, and what companies and organisations could do to improve them.

Essays on trade and environment

Sanctuary, Mark January 2013 (has links)
The thesis comprises four essays examining aspects of international trade and environment. "Border carbon adjustments (BCAs) and Strategic Climate Policy" examines how BCA affects government incentives to regulate emissions and trade in a strategic setting and contrasts the impact of a BCA and a tariff: the distinction being that the level of the BCA is a function of the difference in the trade partner's emission taxes whereas the tariff is not. I show that a BCA leverages the exporter's climate policy provided the exporter has little influence over world prices (i.e. export supply elasticity is large) and has a weak climate policy. "How does the price of electricity affect imports? A study of Swedish manufacturing firms" examines the heterogeneous effects of a domestic electricity price increase on the structure of imports. We identify the magnitude of the impact of the electricity price increase on the structure of firm imports. Our findings agree with the predictions of our theoretical model. "Trade, Transboundary Pollution and Market Size" suggests a new set of theoretical reasons that may help reconcile the contradictory empirical evidence of the impact of trade liberalization on the location of production to countries with weaker pollution policy. Our results suggest that relative market size, the level of trade costs, the ease of abatement, and the degree of product differentiation at the sector level are relevant variables for empirical studies on trade and pollution. Market shares for organic products are typically modest. Yet several consumer surveys find that a majority of respondents would buy substantially more of these products even if they cost more. "What’s holding it back? A study in organic retail coffee purchases" explores reasons for this apparent divergence. The results suggest that the limited overlap between organic and other highly-valued characteristics is one of the most important constraints.

Using Verbal Protocol Analysis to Explore Canadian Consumers' Comprehension of the Nutrition Facts Table

French, Laura J 13 August 2012 (has links)
The current study compared participants’ ability to perform tasks using two nutrition labels: a control Nutrition Facts table of the current Canadian format (n=64), and an experimental label (n=64), identical to the control label with the exception of a footnote explaining how to interpret percent daily values. A 25% subset of participants answered questions using a think aloud technique, and data was analyzed using content analysis. The main outcome measured was ability to interpret percentages correctly, with ability to compare, define and manipulate information as secondary outcomes. No significant differences were seen in ability to perform tasks between the experimental and control conditions for any outcomes. As determined by chi square tests, higher performance was associated with higher education, being male, and report of previous Nutrition Facts table use. Verbal protocol analysis identified that interpretation of percentages was based on the meal, food type, and comparison to other foods.

Maisto produktų ženklinimas ir vartotojų teisių apsauga / Food labelling and consumer protection

Petrauskaitė, Inga 24 January 2012 (has links)
Magistro baigiamojo darbo tikslas - ištirti maisto produktų ženklinimo ir vartotojų teisių apsaugos teisino reglamentavimo ypatumus. Tam, kad būtų pasiektas numatytas tikslas, darbe buvo iškelti šie pagrindiniai uždaviniai: išanalizuoti maisto produktų ženklinimo teisinio reglamentavimo ypatumus Europos Sąjungos ir Lietuvos teisės aktuose; išnagrinėti reikalavimų ženklinant ekologiškus ir maisto priedų turinčius maisto produktus teisinį reguliavimą; išnagrinėti vartotojo galimybes neteisminiu keliu realizuoti savo teises maisto produktų ženklinimo srityje. Vienas iš Europos Sąjungos maisto saugos politikos tikslų – užtikrinti, kad maisto produktai būtų ženklinami. Todėl pirmame darbo skyriuje išanalizavus maisto produktų ženklinimo teisinį reglamentavimą galima teigti, jog šios srities ženklinimas Europos Sąjungoje yra reglamentuojamas horizontaliais ir vertikaliais teisės aktais. Naujuoju Europos Parlamento ir Tarybos 2011 m. spalio 25 d. reglamentu Nr. 1169/2011 siekiama sujungti šiuo metu galiojančius teisės aktus dėl maisto produktų ženklinimo, juos konsoliduoti bei supaprastinti. Pagrindiniu teisiniu dokumentu, reglamentuojančiu maisto produktų ženklinimą Lietuvos Respublikoje, yra laikoma Lietuvos higienos norma HN 119:2002 „Maisto produktų ženklinimas“. Plečiantis tiek ekologiškų, tiek maisto priedų turinčių maisto produktų rinkai, antrame darbo skyriuje nagrinėjami teisės aktų keliami reikalavimai šių produktų ženklinimui. Teisės aktų, reglamentuojančių ekologiškų... [toliau žr. visą tekstą] / The goal of this master thesis is to complete a research on the legal regulation peculiarities of food labelling and consumer protection. In order to achieve the set goal, following tasks were formed in this thesis: to analyze the legal regulation peculiarities of food labelling in legislation of European Union and Lithuania; to analyze legal regulation of requirements for labelling organic food and products that contain food additives; to provide insights regarding possibilities for consumers to implement their rights in the sphere of food labelling. One of the goals of the European Union food safety policy is to ensure the labelling of food. Therefore, after analysing the legal regulation of food labelling in the first section of the thesis, a proposition can be made that, the labelling of this sphere in the European Union is regulated by horizontal and vertical legislation. The new regulation No. 1169/2011, issued by the European Parliament and Council on the 25th of October, seeks to join, consolidate and simplify currently valid legislation regarding food labelling. The main legal document which regulates food labelling in the Republic of Lithuania is Lithuanian Hygiene Norm HN 119:2002 “Food Labelling”. While the market of both organic food and products that contain additives continues to develop, the second section of the thesis analyzes the requirements set by legislation for labelling such products. The analysis of legislation that regulates the labelling of... [to full text]

A model of consumers' perceptions of food additives and consequent purchasing behaviour / Emmerentia Gertruida Dicks

Dicks, Emmerentia Gertruida January 2007 (has links)
The primary objective of this study was to apply the Elaboration Likelihood Model of persuasive communication to consumers' perceptions of food additive labelling. The model was used to explain how consumer information processing influences consumers' decision-making and consequent purchasing behaviour with regard to food products that contain food additives. To date, few studies have explained consumers' perceptions, viewpoints and understanding of additive labelling, or of their related purchasing behaviour. However, the increased marketing of processed foods containing additives and the concern expressed by consumers regarding the risks of additives call for the development of a theoretical basis for research into these issues. There is currently a lack of such data in South Africa. This study was conducted from a phenomenological qualitative approach with a descriptive exploratory nature. Eight focus group sessions with 39 food additive label readers were held in the Vanderbijlpark-Vereeniging area. A content analysis of the focus group discussions resulted in the categorising of concepts, and 33 subtle underlying themes were identified. The main findings of the study were that the participants' general perceptions suggested that food additives can be defined as unnatural chemical substances that are added to food and that hold some benefits and/or risks to the consumer. The participants' use of food additive information was influenced by the situational factors associated with each individual participant. Moreover, the participants were more aware of tartrazine, MSG and aspartame than of any other food additive. Participants were also confronted with various blocking mechanisms when searching for and selecting food products containing additives. These included a lack of standardisation of terminology, illegible ingredient listing, a lack of food control and regulation, information overload, incomprehensible information, manufacturers' dishonesty, time constraints and incorrect, untrustworthy, insufficient information. On the other hand, participants used various coping or risk-reducing strategies to reduce their concerns. In order to interpret the results, the Elaboration Likelihood Model of persuasive communication was adapted and applied to food additive labels. The adapted model illustrates how the consumers' perceptions of additive labels and their search for additional information influence their purchasing behaviour to varying extents. It is recommended that more attention be given to consumer education with regard to additive-related terminology used on food labels and that the results be put to use in the current revision of labelling regulations. Marketers and retailers could use the information to better understand the behaviour of consumers who read food additive labels. The value of this study was to show that consumers' prior perceptions of food additives are an important determinant of their purchasing behaviour, / Thesis (Ph.D. (Consumer Science))--North-West University, Potchefstroom Campus, 2008.

Värderingar och villighet att betala extra : En kvantitativ studie gällande miljömärkning och social produktmärkning av mobiltelefoner / Personal values and willingness to pay more : A quantitative study regarding eco-labelled and fairtrade mobile phones

Gavelin, Sara, Sjöström, Anna January 2014 (has links)
Värderingar är ett centralt begrepp inom psykologin och handlar om vad man anser vara viktigt i livet. Tidigare forskning har fokuserat på hur värderingar påverkar människors vilja att betala mer för livsmedel som har miljö- eller social produktmärkning. Syftet med denna studie var att undersöka värderingar och viljan att betala extra för en mobiltelefon med miljö- eller social produktmärkning hos personer i Uddevalla, Vänersborg och Trollhättan. Resultaten påvisade att de deltagare som var villiga att betala extra för mobiltelefoner med social produktmärkning lade störst vikt vid värderingen solidaritet och de deltagare som var villiga att betala extra för mobiltelefoner med miljömärkning lade störst vikt vid välvilja. Detta resultat ligger i linje med tidigare forskning. I studien deltog 79 slumpmässigt utvalda män och kvinnor mellan 18 och 64 år. Studien var kvantitativ och använde sig bland annat av Schwartz Portrait Values som mätinstrument / Personal values are an important part of psychology and concerns what people consider to be of importance in their lives. Recent studies have focused on the effect personal values have on people’s willingness to pay when it comes to fair trade and eco-labelled food. The purpose of this study was to examine personal values linked to willingness to pay when it comes to a fairtrade or eco-labelled mobile phone, regarding people who live in three closely situated towns in western Sweden. The participants in this study were 79 men and women in the ages 18 – 64. This was a quantitative study and one of the instruments used were Schwartz Portrait Values. The results show that people who found the values benevolence and univeralism to be most important where those who were willing to pay more for these kind of mobile phones. The result is consistent with earlier studies
