abstract: In two independent and thematically connected chapters, I investigate consumers' willingness to pay a price premium in response to product development that entails prosocial attributes (PATs), those that allude to the reduction of negative externalities to benefit society, and to an innovative participatory pricing design called 'Pay-What-You-Want' (PWYW) pricing, a mechanism that relinquishes the determination of payments in exchange for private goods to the consumers themselves partly relying on their prosocial preferences to drive positive payments. First, I propose a novel statistical approach built on the choice based contingent valuation technique to estimate incremental willingness to pay (IWTP) for PATs that accounts for consumer heterogeneity, dependence in the decision making processes, and incentive compatibility. I validate the approach by estimating IWTP for a variety of PATs and contrast the theoretical and managerial benefits of using the proposed approach over extant techniques used in the literature for this purpose. Second, I propose a general and flexible statistical modeling framework for estimating PWYW payments that exceed zero. It relies on the joint estimation of three types of consumer decision processes namely, the consumer propensity to default to an explicit price recommendation, the propensity to pay a least legitimate price, and the payment of a freely-chosen non-zero payment. Of particular interest is the model's ability to account for a wide variety of design constraints such as the setting of price bounds, explicit price recommendations, and the provision of a menu of discrete prices to choose from. I validate the approach by estimating PWYW payments for a variety of products such as music licenses, snacks, and sports tickets. I specifically examine and report the differential impact of three managerially controllable variables namely, 'payment anonymity', 'information on payment recipients' and 'information of product value/quality'. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2016

In the past few decades people’s attitude towards music consumption has tremendously changed in China. With the constantly rising market and huge potential space, it is necessary to study the consumer behavior and explore factors that decide people’s willingness to pay in music consumption. Therefore, the purpose of this thesis is to investigate: 1) What factors may influence the Chinese consumer behavior on music and its merchandise; 2) What factors may influence the “willingness to pay” of Chinese consumer in music consumption; 3) The similarities and differences between the consumption of music product and musical merchandise in China. The authors select the qualitative method and set up two focus groups, music product group and music merchandise group, in this study. Finally, they found five dimensions (musical preference & identity, culture of music, musical loyalty & satisfaction, Chinese music consumption, willingness to pay) will interaction with each other and influence Chinese consumer behavior on music product and its merchandise.

L'acédie alliée à la mélancolie nous permet de rendre compte de la totalité de la nature humaine, en tant qu'elle est composée d'une âme, d'un esprit et d'un corps. Ces deux pathologies distinctes autant par leur inscription dans un temps et un espace particuliers et déterminés, ainsi que par les dimensions de l'être humain auxquelles elles s'attaqueront se verront ici rapprochées de sorte à faire émerger un paradigme qui fera de la folie pathologique un moyen d'accès au divin. La mélancolie, de par son bagage grec antique qui faisait d'elle l'apanage des hommes de génie, contaminera au XIIIe siècle l'acédie au point que celle-ci ne sera plus envisagée sous la perspective d'une passion, d'un vice - le plus redoutable de tous – mais une grâce, cherchée et convoitée par les saints hommes de cette époque, selon Guillaume d’Auvergne. Pour ce faire, l'acédie se révélera être une pathologie de la volonté en tant que celle-ci se voit éteinte, asphyxiée devant un idéal inaccessible qui épuiserait en elle tout dynamisme, idéal de l'impassibilité que l'on retrouve sous les traits de l'ange chez les Pères du désert et celui de la performance que l'on retrouve sous les traits du surhomme à notre époque, deux modèles qui se voient être pervertis dès leur conception et dévoilés comme tel par l'acédie. D'une maladie mortelle, celle qui vient autant emporter le corps de l'ascète que la vie de son âme, se révèle protéger l'individu d'un mal encore plus redoutable, celui de l'orgueil, en venant par la même occasion préserver la puissance de la volonté de l'individu en celle de Dieu par le truchement d'une grâce divine. Eau de mort pour le commun des mortels, elle devient eau de vie, porteuse d'une grâce efficace, pour les fous de Dieu dont la folie n'a d'égale que leur amour ; l'acédie devenant par là-même la maladie de l'amour fou de Dieu. / Acedia combined with melancholy allows us to account for the totality of human nature, insasmuch as it is composed of a soul, a spirit and a body. These two distinct pathologies, as much by their inscription in a particular and determined time and space, as by the dimensions of the human being that they will attack, will be brought together here in such a way as to bring forth a paradigm that will make pathological madness a means of accessing to the divine. Melancholy, by its ancient Greek heritage, which made it the prerogative of men of genius, will contaminate acedia in the thirteenth century to the point that it will no longer be considered from the perspective of a passion, a vice – the most awe-inspiring of all – but a grace, sought for and coveted by the holy men of that time, according to William of Auvergne. For this to happen, acedia will prove to be a pathology of the will inasmuch as it is extinct, asphyxiated in the face of an inaccessible ideal that would exhaust all dynamism, ideal of the impassibility that we find under the features of the angel of the Desert Fathers and that of the performance that we find under the features of the übermensch in our time, two models that become perverted from the time they were conceived and unveiled as such by the acedia. From a mortal disease, the one that takes away both the body of the ascetic and the life of his soul, is revealed to protect the individual from an even more dangerous evil, that of pride, by coming at the same time to preserve the power of the individual's will in that of God through the means of divine grace. Water of death for the common man, it becomes water of life, bearer of an efficacious grace for the fools of God, whose madness is matched only by their love ; acedia thereby becoming the disease of God's love.

The human values and the belief in a just or unjust world was the independent variables, considering a cross-cultural sample. In this sense, two empirical studies was performed. The Study 1 considered a sample of 723 subjects, with mean age of 26.5 years old (DP = 9,10), mostly composed by women (73,3%), and distributed on 5 countries: Argentina (n =54), Brazil (n =330), Spain (n = 154), Mexico (n = 83) and Portugal (n = 102). They answered to General Just World Scale, Unjust Word Scale, Willingness to Forgive Scale, Basic Values Questionnaire and demographic questions. The results pointed to the formulation of a theoretical model involving the Personal goals (excitement and promotion) and beliefs in just and unjust world, predicting the explicit willingness to forgive. This model looks satisfactory by the empirical data observed: [χ²/gl = 7,26, GFI = 0,98, AGFI = 0,94, CFI = 0,91 e RMSEA = 0,09 (0,063 – 0,013)]. The Study 2 aimed: a) adapt an implicit measure of willingness to forgive (IAT- Forgiveness) for the five countries; b) know the implicit correlates of willingness to forgive and c) develop a alternative model to explain this willingness, involving the values and beliefs. Was counted with a sample of 449 participants, from five different countries. These had a mean age of 25.5 years (SD = 8.40) most female (72.6%). In order to achieve the objectives, the sample was divided by country: Argentina (n = 41), Brazil (n = 200), Spain (n = 84), Mexico (n = 76) and Portugal (n =48). The IAT - Forgiveness was given together with the same questionnaires of Study 1. The results showed that the implicit measurement presented predictive validity. It also revealed that people in five countries showed implicit willingness to forgive, and that this willingness correlaciou positively with social goals (interactive and normative) and with the beliefs in a just world and inversely with the belief in an unjust world. The second theoretical model also presented appropriate indices: [χ²/gl = 3,09, GFI = 0,99, AGFI = 0,96, CFI = 0,93 e RMSEA = 0,07 (0,27 – 0,11)]. It is estimated that the objectives were achieved, with the adaptation of of an implicit measure of willingness to forgive for five countries, with preliminary evidence of its validity, and increasing the understanding that has been around willingness to forgive from the relationships it establishes with other constructs. / Esta dissertação objetivou elaborar um modelo explicativo da disposição para perdoar, utilizando instrumentos explícito e implícito, tendo, como variáveis independentes, os valores humanos, a crença no mundo justo e injusto, considerando uma amostra transcultural. Neste sentido, dois estudos empíricos foram levados a cabo. O Estudo 1 considerou uma amostra total de 723 participantes, cuja idade média foi de 26,5 anos (DP = 9,10), em maioria mulheres (73,3%), distribuídos em cinco países: Argentina (n = 54), Brasil (n = 330), Espanha (n = 154), México (n = 83) e Portugal (n = 102). Estes responderam à Escala Geral de Crença no Mundo Justo, Escala de Crenças no Mundo Injusto, Escala de Disposição para Perdoar, Questionário de Valores Básicos e perguntas demográficas. Os resultados apontaram para elaboração de um modelo teórico envolvendo os valores pessoais (experimentação e realização) e as crenças no mundo justo e injusto, predizendo a disposição para perdoar explícita. Este modelo se mostrou satisfatórios aos dados empíricos: [χ²/gl = 7,26, GFI = 0,98, AGFI = 0,94, CFI = 0,91 e RMSEA = 0,09 (0,063 – 0,013)]. O Estudo 2 teve os seguintes objetivos: a) adaptar uma medida implícita de disposição para perdoar (TAI- Perdão) para os cinco países; b) conhecer os correlatos implícitos da disposição para perdoar e c) elaborar um modelo alternativo para explicar essa disposição, envolvendo os valores e as crenças. Contou-se com uma amostra de 449 pessoas dos mesmos países do Estudo 1. Estes tinham idade média de 25,5 anos (DP= 8,40) em maioria mulheres (72,6%). A fim de realizar os objetivos, a amostra foi dividida segundo os países: Argentina (n = 41), Brasil (n = 200), Espanha (n = 84), México (n = 76) e Portugal (n = 48). O TAI – Perdão foi administrado em conjunto com os mesmos instrumentos do Estudo 1. Os resultados mostraram que a medida implícita apresentou validade preditiva. Revelou também que as pessoas dos cinco países apresentaram disposição implícita para perdoar, e que esta disposição se correlaciou positivamente com os valores sociais (interativa e normativa) e as crenças no mundo justo e inversamente com a crença no mundo injusto. O segundo modelo teórico também apresentou índices adequados: [χ²/gl = 3,09 GFI = 0,99, AGFI = 0,96, CFI = 0,93 e RMSEA = 0,07 (0,27 – 0,11)]. Estima-se que os objetivos propostos foram alcançados, com a adaptação transcultural de uma medida implícita de disposição para perdoar, apresentando evidências preliminares de sua validade, além de aumentar o entendimento que se tem em torno da disposição para perdoar a partir das relações que ela estabelece com outros construtos.

Assign an economic value to environmental resources is not yet a widespread practice. The environmental management has been focused mainly on assessment of the impacts generated by the unbalanced exploitation of these resources. Therefore, this work has as overall goal performing economic valuation of Dunes State Park of Natal in Natal/RN, analyzing the Willingness to Pay (WTP) for students and employees of the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) through Contingent Valuation Method (CVM), considering its natural attractions, and specific objectives, we analyze the socioeconomic profile of students and employees and their concerns about environmental issues, as well we estimate the function WTP for the use of environmental attractions of the park. Finally, we relate the value of the WTP Park socioeconomic characteristics of the students and IFRN servers. As methodology, we used a bibliographic review of the existing literature and a field research, executed at Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN), Natal-campus center, where we applied a questionnaire in the open form of elicitation, during September of 2012, among students aged 18 years and servers (administrative staff and teachers) of this educational institution, gathering also socioeconomic information of the individuals. The results demonstrated that through the regression model, analyzed in general, we have evidence for a significance level of 6,8% there is a significant difference between the amount willing to pay for the maintenance of the park with family income and net income, in other words, as the individual has a higher net income and family, value willing to pay for the maintenance of the Dunes state Park tends to be higher. Furthermore, it was detected that there is also significant effect with respect to schooling, where as you increase the educational level of the individual, the average willing to pay for the maintenance of the Dunes state Park also increases. A fact relevant as adjustments in the general model, it is found not to have significant effect on the amount willing to pay for the maintenance of the Dunes state Park with respect to students and servers. / A valoração econômica de ativos ambientais tem ganhado relevância como instrumentos para auxiliar a tomada de decisão tanto de gestores públicos e legisladores, como de investidores e empresários. Atribuir um valor econômico aos recursos ambientais não é, ainda, uma prática difundida. A gestão ambiental tem se preocupado principalmente na avaliação dos impactos gerados pela exploração desequilibrada desses recursos. Logo, este trabalho tem como objetivo geral realizar a valoração econômica do Parque Estadual Dunas de Natal, em Natal/RN, analisando a Disposição a Pagar (DAP) de alunos e servidores do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) por meio do Método de Valoração Contingente (MVC), considerando seus atrativos naturais; e como objetivos específicos, analisamos o perfil socioeconômico de alunos e servidores e de seus interesses sobre as questões ambientais, bem como estimamos a função DAP pelo uso dos atrativos ambientais do parque. E, por fim, relacionamos o valor da DAP do parque às características socioeconômicos dos discentes e servidores do IFRN. Como metodologia, utilizamos uma revisão bibliográfica da literatura existente e uma pesquisa de campo, realizada no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Câmpus Natal-Central, onde aplicamos um questionário na forma aberta de eliciação, durante o mês de setembro de 2012, entre os alunos maiores de 18 anos e servidores (técnicos administrativos e professores) desta instituição de ensino, reunindo também informações socioeconômicas dos indivíduos amostrados. Os resultados demonstraram que, através do modelo de regressão, analisado de forma geral, temos evidências para um nível de significância de 6,8% que existe diferença significativa entre o valor disposto a pagar pela manutenção do parque com renda familiar e renda líquida, ou seja, a medida que o indivíduo possui maior renda líquida e familiar, o valor disposto a pagar pela manutenção do Parque das Dunas tende a ser maior. Além disso, foi detectado que existe efeito significativo também com relação ao grau de escolaridade, onde a medida que aumenta o grau de escolaridade do indívíduo, o valor médio disposto a pagar pela manutenção do Parque das Dunas também aumenta. Um fato relevante visto nos ajustes do modelo geral, trata-se de não ter encontrado efeito significativo no valor disposto a pagar pela manutenção do Parque das Dunas com relação aos estudantes e servidores.

The environmental goods and services cannot be valued through markets economically defined. Therefore, it has been necessary to implement methodologies such as contingent valuation for this purpose. This method was proposed 66 years ago and it has been widely used in different fields such as conservation of protected areas. The aim of this article is to provide a theoretical review of the contingent valuation method and to show experiences of its application in the assessment of Protected Areas in Latin America. In the sixties and seventies contingent valuation began to acquire greater importance for estimates of non-use values. Then, there was a cross-disciplinary integration of elements to strengthen the development of surveys and in the nineties appeared a criticism of its validity .Moreover, contingent valuation studies in Latin American countries have had positive results in determining the willingness to pay for recreational value, environmental services value, social benefits and public management of protected areas. / Los bienes y servicios ambientales no pueden ser valorados económicamente a través de mercados definidos, por lo que ha sido necesario la implementación de metodologías como la valoración contingente para dicho fin. Este método fue planteado hace 66 años y desde entonces ha sido ampliamente empleado en diversos campos como la conservación de áreas protegidas. El presente artículo hace una revisión teórica del método de valoración contingente y de las experiencias de su aplicación en la valoración de áreas protegidas en América Latina.En los años sesenta y setenta la valoración contingente comenzó a adquirir más importancia para la estimaciones de valores de no uso; posteriormente hubo una integración de elementos transdisciplinares para fortalecer la elaboración de encuestas y en los años noventa surgieron críticas sobre su validez. Asimismo, los estudios de valoración contingente en países latinoamericanos han tenido resultados positivos en la determinación de la disposición a pagar por aspectos como valor recreativo, valor de servicios ambientales, beneficios sociales y gestión pública de espacios protegidos.

Cette thèse vise analyser les déterminants (objectifs et subjectifs) à l’origine de l'hétérogénéité des évaluations de projets. Dans un premier temps, j'analyserai comment les quantités (objectives) sont incorporées dans l'analyse coût-bénéfice. Le premier chapitre principal traite de la manière dont l'analyse coût-bénéfice est affectée par la distribution temporelle des impacts considérée. À travers l'exemple du changement d'affectation des terres provenant de la production de biocarburants, il ressort que les décisions concernant les projets ayant des impacts environnementaux non constants dans le temps s'appuient sur des valeurs actuelles nettes biaisées, ce qui peut entraîner la mise en œuvre de projets en réalité non souhaitables ou la non-implémentation de projets réellement souhaitables. Ce travail est à la fois théorique et numérique.Ensuite, j'étudie le rôle de la structure des préférences sur la prise de décision individuelle dans un cadre individuel puis un cadre collectif. Au niveau individuel, nous développons un modèle théorique qui permet soit de la substituabilité, soit de la complémentarité entre les biens en fonction du contexte (revenu et qualité de l'environnement). Il en résulte que l'élasticité-revenu du consentement à payer marginal peut être négative dans un contexte de substituabilité inter-biens, ce qui contraste avec les modèles habituels qui ne permettent que des élasticités positives du revenu (le bien environnemental ne peut jamais être inférieur mais est toujours normal). Notre cadre théorique affecte également la façon dont la consommation et la qualité de l'environnement sont actualisées, ce qui est d'autant plus pertinent dans un contexte de chocs sur les revenus. Au niveau collectif, j’utilise une approche expérimentale pour analyser l'effet de l'interaction entre les individus ayant des structures de préférences différentes sur les contributions au bien public. Il en résulte que la substituabilité parfaite est associée à un plus grand nombre de passagers clandestins que la complémentarité. Cependant, une aversion à l'inégalité avantageuse émerge également des individus dont les préférences sont à l'origine d'une parfaite substituabilité vis-à-vis de ceux dont les préférences sont fondées sur la complémentarité. / This thesis aims at providing insights on the (objective and subjective) determinants of the heterogeneity of project evaluations. At first, I analyze how (objective) quantities are incorporated in the cost-benefit analysis. The first main chapter deals with the way cost-benefit analysis is affected by the time distribution of impacts considered. Through the example of land use change from biofuel production, I find that decisions regarding projects with non-constant environmental impacts rely on distorted net present values, which may result in the implementation of actually non-desirable projects or the non-implementation of actually desirable projects. This work is both theoretical and numerical.Second, I investigate the role of the structure of preferences, i.e. whether private goods and environmental goods are substitutable or complementary in providing utility, on individual decision-making in an individual framework and a collective framework. At the individual level (second main chapter), we develop a theoretical model which allows either for substitutability or complementarity depending on the context (income and environmental quality). It results that the income elasticity of willingness to pay can be negative in contexts of between-goods substitutability, which contrasts with usual frameworks which only allow for positive income elasticities (thus the environmental good can never be inferior but is always normal). Our framework also affects the way consumption and environmental quality are discounted, which is all the more relevant in the context of income shocks. At the collective level (third main chapter), we use an experimental approach to analyze the effect of the interaction between individuals with different structures of preferences on contributions to the public good. It results that perfect substitutability is associated with more free-riding than complementarity. However, an aversion to advantageous inequality also emerges from individuals whose preferences underlie perfect substitutability towards those whose preferences are based on complementarity.

This paper was conducted with the purpose of estimating a monetary value of leisure (VL) time for the population in Sweden. The model used is developed by Jara-Diaz et. al. (2008). Due to the lack of studies of the value of leisure time for the Swedish population parameter values for Germany and Switzerland was used. This since their population characteristics is most like the Swedish population characteristics and represents both higher and lower levels of taxes and wage rates. The parameter values stand for an average benefit of having leisure time from a study in Karlsruhe, Germany, and Thurgau, Switzerland, and was used in a combination with Swedish statistics to obtain a value of leisure time. Results from Jara-Díaz et. al. (2008) shows that the population in Thurgau has a higher value of leisure time, most likely since they have a higher wage rate and a lower tax than the population in Germany, but the parameters from Germany are higher. The results therefore show a higher value of leisure time with estimates from Karlsruhe. The value of leisure time represents 35%-208% of the wage rate after tax with parameter values from Karlsruhe, and 23%-137% of the wage rate after tax with parameter values from Thurgau. The value of leisure time correlates with income and the result show that to have a positive value one need to have a yearly income closer to 200 000 SEK after tax. For people under 200 000 SEK the value of leisure was negative, in other words, they are unwilling to pay for an hour of leisure time. The results from the model is a form of willingness to pay for one additional hour of leisure time. A Monte Carlo simulation was conducted on the average value of parameter α (average individual preferences of sparing time for consumption) and β (average individual preferences of sparing time for activities). The author assumes that the population in Sweden would be most likely to have an average benefit that is located between the estimates of the average benefit for Karlsruhe and Thurgau. The analysis shows that for people of age 20-64 years the median of leisure time is 165 SEK, and for the younger ones, 16- 19 years, the median value of leisure time is 4 SEK. / Den här uppsatsen gjordes med syftet att ta fram ett monetärt värde för fritid (Value of Leisure, VL) för den svenska populationen. Modellen som används har tagits fram av Jara-Diaz et.al. 2008. I brist på studier av det monetära värdet för fritid för den svenska populationen har parametervärden för andra länder med liknande populationskaraktäristikan jämförts. Valet föll slutligen på Tyskland och Schweiz, då dessa länder även representerar högre och lägre nivåer av skatt och löner jämfört med Sverige. Parametervärdena står för en genomsnittlig nytta av att ha fritid från en studie gjord i Karlsruhe, Tyskland och i Thurgau, Schweiz och används i kombination med svensk statistik för att få fram ett värde av fritid. Resultat från Jara-Díaz et. al. (2008) visar att populationen i Thurgau har ett genomsnittligt högre värde på fritid, troligtvis för att de har en högre genomsnittlig timlön och en lägre skatt än populationen i Karlsruhe, men parametervärden från Karlsruhe är högre än de från Thurgau. Studiens resultat visar därför ett högre värde av fritid med parametervärden från Karlsruhe. Värdet sträcker sig mellan 23%- 137% av lönenivån efter skatt med estimat från Thurgau och mellan 35%-208% av lönenivån efter skatt med estimat från Karlsruhe. Värdet för fritid korrelerar med inkomsten och siffrorna visar att individen behöver ha en årsinkomst på närmare 200 000 kr efter skatt för att ha ett positivt värde. För de som tjänar under 200 000 kr är värdet negativt, med andra ord, de är ovilliga att betala för fritid. Resultatet från modellen är en form av betalningsvilja för att få ytterligare en timma fritid. En Monte Carlo simulering har gjorts med genomsnittet av α (genomsnittlig individuella preferenser att avvara tid för konsumtion) och β (genomsnittlig individuella preferenser att avvara tid till aktiviteter). Detta eftersom författaren anser att populationen i Sverige sannolikt skulle ha en genomsnittlig nytta som är värderad mellan den genomsnittliga nyttan för Karlsruhe och Thurgau. Analysen visar att medianen för värdet av fritid är 165 SEK för individer 20-64 år, och för de yngre, 16-19 år, är medianen för värdet av fritid 4 SEK.

A exigência de consumidores por alimentos originados de sistemas que forneçam boas condições de vida aos animais de produção consiste numa realidade em inevitável crescimento. Legislações internacionais elaboradas por demanda de mercado pressionam os produtores e a indústria brasileira a cumprir normas que estabelecem padrões mínimos de bem-estar animal (BEA). No caso específico da suinocultura, um dos aspectos mais polêmicos é o alojamento das matrizes durante a gestação. As gaiolas individuais, sistema convencional no Brasil, promove limitação física e social, além de predispor a distúrbios locomotores e comportamentais. Por outro lado, o sistema proposto para melhorar o BEA, as baias coletivas, provocam outros problemas, como as brigas por disputa hierárquica e por alimento, e o baixo controle individual, que poderiam prejudicar o desempenho reprodutivo. Dessa forma, um equipamento individual de arraçoamento automatizado (ESF) foi desenvolvido para amenizar essa situação. Para descobrir o efeito do alojamento em grupo com o ESF no desempenho reprodutivo das matrizes, foi realizada uma comparação de dados reprodutivos dos dois sistemas, localizados numa mesma propriedade. Dados mensais de três anos foram coletados dos registros das granjas e analisados por teste T-Student para as variáveis paramétricas e por teste de Mann-Whitney para as não paramétricas. De acordo com os resultados, o desempenho das matrizes alojadas em baias foi superior. Apenas a média do peso do leitão ao nascimento foi significantemente inferior em relação ao sistema individual, sugerindo que a conversão de sistemas é não apenas favorável ao BEA e ao mercado exigente, mas também para a produtividade. Além da questão do produtor, é essencial avaliar a percepção do consumidor brasileiro quanto ao BEA, visto que seu poder de compra é uma forte influência no mercado, e que apenas as exigências internacionais não são suficientes para provocar mudanças em todos os sistemas de produção do país. Por isso, também foi realizado um levantamento com consumidores. Utilizou-se dois métodos de coleta: online e em campo (pontos de comércio), para uma maior abrangência e representatividade. Os dados coletados foram analisados por estatística descritiva, e o teste Qui-quadrado foi aplicado para avaliar se houve associação entre a distribuição das respostas e o perfil dos participantes. Ambas as pesquisas demonstraram que o consumidor reconhece a senciência dos animais de produção, sente que é dada pouca importância ao tema no Brasil, enquanto consideram o governo como principal responsável por promover melhorias. Concordam que consumir produtos com certificação em BEA pode contribuir para melhorar as condições dos animais, apesar de não conseguirem identificar o selo nas embalagens. Além disso, apesar dos participantes alegarem não conhecer os sistemas de produção atuais, demonstraram interesse sobre o assunto e disposição para pagar mais por produtos certificados. No entanto, algumas respostas devem ser indagadas quando pareadas com o real comportamento do consumidor. / Consumer\'s demand for animal-friendly food is an inevitably growing reality. International legislation drawn up by market demand pressure Brazilian farmers and the industry to comply with minimum animal welfare standards. Specifically in pig production, one of the most controversial aspects is the housing of sows during gestation. Individual crates, which is the conventional system in Brazil, promote physical and social restriction, and predispose to lameness and behavioural disorders. On the other hand, group pens were proposed system to improve animal welfare, but bring other problems, such as hierarchical and food competition aggression, and low individual control, which could impair reproductive performance. In this way, electronic sow feeder (ESF) was developed to mitigate this situation. So, to find out the effect of group housing with ESF system on reproductive performance of sows, a comparison of reproductive data of both systems, located in the same farm, was performed. Monthly data of three years were collected from the farm records and analyzed by T-Student Test for parametric variables and Mann-Whitney Test for the non-parametric variables. According to the results, group housing showed better performance. Only piglet weight at birth was significantly higher in individual housing, suggesting that the conversion of housing systems is not only favourable to farm animal welfare (FAW) and to demanding market, but also to productivity. In addition to the farmer issue, it is essential to evaluate Brazilian consumer\'s perception of FAW, since his/her purchasing power causes strong impact on market. Besides, international legislation is not enough to bring about changes in all Brazilian farms and food industries. Therefore, a consumer survey was conducted. Two data collection methods were used: online and in loco (marketplaces). for greater number of answers and representativeness. Collected data were analyzed by descriptive statistics, and chi-square Test was applied to evaluate if there was association between answers\' distribution and participants\' profile. Both surveys have shown that consumer recognizes farm animals\' sentience, feels that little importance is given to the subject in Brazil, while he/she considers the government as the main responsible for promoting FAW. They agree that consuming animal-friendly products can help improve animals\' conditions, even though they cannot identify certification seal. In addition, while participants claim they are not familiar to farming systems, they have shown interest in the topic and willingness to pay more for certified products. However, some answers should be analyzed when paired with actual consumer behaviour.
