Konsumtionen är ett miljöproblem i Sverige och den behöver ställas om mot en mer cirkulär ekonomi. En del av den cirkulära ekonomin är återanvändning. Återanvändning av saker är mer miljöeffektivt än att materialåtervinning. Trots att kommunala återvinningscentraler erbjuder möjlighet att lämna saker till återbruk slängs betydande mängder återanvändbara saker till energiåtervinning. Genom att kombinera tidigare studiers resultat kring nudging och återvinning med förutsättningarna som råder på Gävle återvinningscentral designades 3 nudges. En nudge använder en beskrivande social norm mot återbruk, en förenklar att återbruka och den sista kombinerar den förenklande nudgen med en beskrivande social norm. Dessa undersöker hur nudging som metod kan förmå avfallslämnare som avser att slänga återanvändbara saker att i stället återbruka dem. Fyra 4 hypoteser ställdes upp kring vilken effekt de framtagna nudges skulle ha och därefter genomfördes ett fältexperiment av författaren. Experimentet gav inget signifikant resultat varvid en diskussion förs kring hur förändringar i metoden skulle kunna påverka resultatet. Författaren anser att det inte går att förkasta de framtagna nudges utan att först genomföra ett modifierat experiment då det finns indikationer som tyder på ett gott utfall trots allt. / Consumption is an environmental issue in Sweden that must adapt towards circular economy. Re-use is a part of circular economy and is more environmentally friendly than material recycling. Even though municipal recycling centrals offers the possibility for their visitors to re-use functioning things, considerable amounts are still thrown to be energy recycled by incineration.  By combining results from studies about nudging and recycling with the conditions, physical and social, of Gävle recycling central, 3 nudges where designed. One uses a descriptive social norm about re-use, the second simplifies the behavior of re-use and the third combines the two previous nudges into one. These will be used to test if nudging as a method can convince waste throwers that intend to throw away re-usable things to re-use them instead. 4 hypotheses were formulated about the effect of the designed nudges and then a field experiment was conducted by the author. The experiment did not yield a significant result. The discussion focuses on how changes in the methodology could affect the result to make it more robust. The author is not ready to reject the designed nudges without testing them in a modified experiment as there are indications pointing towards a potential good result after all.

Sopsortering på tåg är ett ämne där det saknas vetenskaplig litteratur. Det framstår utifrån författarnas egna observationer som att sopsortering på tåg inte förekommer. De alternativ som observerats är plastpåsar vid tågsäten och en lucka i väggen för blandat avfall. Det är troligt att avfallet går till förbränning då det inte finns några lagar eller regler som kräver att sopsortering ska finnas på tåg. Vetskapen om att ämnet inte undersökts och att det verkar saknas sorteringsalternativ på tåg, la grunden för arbetets syfte. Syftet var att undersöka hur människor upplever sorteringsmöjligheterna på tåg och potentialen att öka insamling med hjälp av bättre sorteringsmöjligheter och prompts. För att besvara syftet, formulerades två frågeställningar,1.Hur upplever människor sorteringsmöjligheterna på tåg, och kan olika typer av sorteringsmöjligheter förbättra dessa? Och, 2.Hur kan prompts användas för att öka sorteringen av pappersavfall på tåg? Teoriavsnittet var grundläggande för både metod, resultat och diskussion. Kapitlet berörde bland annat prompts, normativ påverkan, åtgärder för att kunna förbättra återvinning och en beskrivning av en fältstudie meden observation och utdelandet av flygblad.I arbetet valdes en enkätstudie för att få svar på frågeställning 1. Enkätens huvudsakliga resultat var tvetydigt, det gick inte helt säkert se att de valda interventionerna ökade sorteringsmöjligheterna. För att försöka få tydligare svar och för att få svar på fråga 2. genomfördes ett fältexperiment. Resultatet av fältexperimentet blev inte signifikant. I diskussionen lyftes de huvudsakliga resultaten från enkätundersökningen och fältexperimentet. Resultatet jämfördes med tidigare studier och styrkor och brister med arbetets utförande diskuterades. Slutligen gavs svar angående om syfte och frågeställningar hade besvarats. / Waste recycling on trains is a subject that lacks scientific literature. It seems from the writers own observations that recycling on trains is non existent. The alternatives that have been observed is plastic bags next to train seats and a gap in the wall for mixed waste. It is probable that waste goes to incineration because there is no laws or rules that demand waste recycling on trains. The knowledge about the subject not being researched and that recycling seems to be absent on trains, lay the foundation for this works aim. The aim was to research how people feel the possibilities to recycle on trains are and the potential to increase recycling with better alternatives for recycling and prompts. To answer the aim, two questions were formulated, 1. How does people experience waste recycling possibilities on trains, and can different types of waste recycling possibilities make them better?And, 2. How can prompts be used to increase waste recycling of paper on trains?The theory section was the basis for both method, results, and discussion. The chapter touched on for instance prompts, normative influence, actions to improve recycling and a description of a field study with an observation and the handing out offlyers. In this work a survey was chosen to answer research question 1. The main results of the survey were inconclusive, it was not possible with full certainty to saythat the chosen interventions increased recycling possibilities. To get a clearer answer and to get the answer to question 2. a field experiment was performed. The results of the field experiment were not significant. In the discussion the main results from the survey and field experiment were aired. The results were compared to prior studies and strengths and weaknesses with the work performance was discussed. Finally answers were given about if the aim and research questions had been answered.

This thesis consists of five essays on the economic outcomes of immigrants and homosexuals on the labour and housing market. Essay I evaluates the effect of an in-work benefit on the labour supply of single immigrant women by means of simulation. Although, on average, there is no significant effect, we find that the in-work benefit increases the working hours of single women with low incomes and slightly decreases the working hours of those with high incomes. The increase in working hours is primarily a result of increased participation. As expected, the positive effect is largest for the immigrant groups with the lowest participation rates and lowest labour incomes. Essay II studies intergenerational transmissions in self-employment. The results show that immigrants transfer general human capital over three generations in the sense that individuals whose fathers and grandfathers are self-employed have a higher self-employment propensity. For natives, only the father’s self-employment affects the son’s probability of becoming self-employed. Furthermore, the results show that natives transfer specific human capital from father to son, which increases the probability of sons becoming self-employed in the industry in which their fathers are self-employed. Essay III explores the effect of self-employment experience on subsequent earnings and the employment of male and female immigrant wage earners. We find that, relative to continued wage employment, self-employment is associated with lower earnings and difficulties in returning to paid employment for both immigrant men and women. The effect is less severe for natives. Among immigrant groups, the results give little support that self-employment experience improves earnings and employment prospects compared to experience from wage employment.  Essay IV applies a field experiment to investigate how increasing the information about applicants affects discrimination against male Arab/Muslim applicants on the rental housing market. The Arab/Muslim applicants received fewer responses from the landlords than did the Swedish applicants. All of the applicants gained by providing more information about themselves, but the magnitude of discrimination against the Arab/Muslim applicants remained unchanged, indicating that increasing the amount of applicant information will not reduce discrimination. Essay V studies possible discrimination against lesbians in the rental housing market using a field experiment. We let two fictitious couples, one heterosexual and one homosexual, apply for vacant apartments on the Internet. We then explored if there were differences in callbacks, invitations to further contact and/or showings. The results show no indication of differential treatment of lesbians by landlords.

In this thesis, I report the results from the first randomized field experiments conducted in collaboration with party-affiliated candidates and campaigns in the United Kingdom. The papers presented as part of this thesis test both the limits and possibilities of campaign influence, in a partisan political environment. During election campaigns parties provide signals to voters, voluntarily or involuntarily imposing a structure, and thereby constraints, on individuals’ electoral decisions. By integrating insights about heuristic and social decision-making into the experimental campaign literature, I formulate testable hypotheses about the direct and indirect effects of party cues on campaign mobilization and persuasion. The first paper, The Heuristic Function of Party Affiliation in Voter Mobilization Campaigns, addresses how the provision of party cues, used during campaign phone calls, affects turnout among party supporters, opponents and unattached voters. The second paper on Household Partisan Composition and Voter Mobilization, explores the spillover effects from the previous experiment, testing whether campaign-induced mobilization between household members is conditioned by the partisan composition of a household, and the partisan intensity of a campaign message. Paper three investigates if candidates who are Reaching Across The Partisan Divide can win over supporters of rival parties. In the fourth paper, I test if Impersonal, But Noticeable methods of voter contact, such as door hangers and text messages, affect the turnout decisions of partisans and unattached voters. The final paper, The National Effects of Subnational Representation, highlights the importance of local party organization for the outcomes of national elections. The results of this thesis show the electoral consequences of direct and indirect interactions between campaigns and voters of different partisanship, and point to strategies that allow constituency campaigns to successfully navigate challenging partisan environments.

Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. In this context, processes related to CO2 trapping and also possible leakage of CO2 to the near surface environment need to be understood. The overall aim of this thesis is to understand the flow and transport of CO2 through porous media in the context of geological storage of CO2. The entire range of scales, including the pore scale, the laboratory scale, the field experiment scale and the industrial scale of CO2 injection operation are addressed, and some of the key processes investigated by means of experiments and modeling.  First, a numerical model and laboratory experimental setup were developed to investigate the CO2 gas flow, mimicking the system in the near-surface conditions in case a leak from the storage formation should occur. The system specifically addressed the coupled flow and mass transport of gaseous CO2 both in the porous domain as well as the free flow domain above it. The comparison of experiments and modelling results showed a very good agreement indicating that the model developed can be applied to evaluate monitoring and surface detection of potential CO2 leakage. Second, the field scale CO2 injection test carried out in a shallow aquifer in Maguelone, France was analyzed and modeled. The results showed that Monte Carlo simulations accounting for the heterogeneity effects of the permeability field did capture the key observations of the monitoring data, while a homogeneous model could not represent them. Third, a numerical model based on phase-field method was developed and model simulations carried out addressing the effect of wettability on CO2-brine displacement at the pore-scale. The results show that strongly water-wet reservoirs provide a better potential for the dissolution trapping, due to the increase of interface between CO2 and brine with very low contact angles. The results further showed that strong water-wet conditions also imply a strong capillary effect, which is important for residual trapping of CO2. Finally, numerical model development and model simulations were carried out to address the large scale geological storage of CO2 in the presence of impurity gases in the CO2 rich phase. The results showed that impurity gases N2 and CH4 affected the spatial distribution of the gas (the supercritical CO2 rich phase), and a larger volume of reservoir is needed in comparison to the pure CO2 injection scenario. In addition, the solubility trapping significantly increased in the presence of N2 and CH4.

Dar nitidez aos sentimentos e razões que emergem das experiências dos vestibulandos de Vitória-ES, entre 2009-2010, e que os movem em direção a seus projetos profissionais é objetivo deste trabalho. A noção de projeto aqui utilizada (VELHO, 1999) afasta-se da clássica compreensão liberal do ser humano, autônomo, livre e único, responsável por seus sucessos e fracassos, subjacente a estudos sobre escolha profissional. A ideia proposta é que campo de experiências dos sujeitos marca seus projetos profissionais, mas que suas condutas deliberadas, não necessariamente racionais, expõem certas expectativas de vida, quaisquer que sejam as posições sociais desses sujeitos. Para o exame dessas expectativas, esses sujeitos foram vistos em suas relações sociais - nas interseções de classes, gênero, de cor da pele, de gerações, etc. Reconheceu-se, ainda, que razões e sentimentos (WILLIAMS, 1969), também forjam projetos profissionais de sujeitos sob diversas condições sociais e apesar delas. Por considerar que esses projetos portam manifestações humanas, nem sempre perceptíveis e tantas vezes encobertas, a metáfora do rizoma (DELEUZE; GUATTARI, 2004), foi de utilidade metodológica. Alguns indícios (GINZBURG, 2007), sugeriram caminhos de pesquisa e alguns dos significados aos sujeitos para que esses projetos pudessem ser detectados. A perspectiva da longa duração histórica e dos tempos múltiplos presidiu o exame de trajetórias selecionadas de um conjunto de sujeitos pesquisados entre os anos 2009-2010, o que favoreceu a percepção de continuidades históricas, mas também a ocorrência de mudanças de certas tendências sociais. Dois cursos de pré-vestibular, um público e um privado, em Vitória, ES, nessa conjuntura, mostraram um pouco da pluralidade de expectativas de diferentes jovens - pobres, de classes média e alta, homens e mulheres, brancos, negros e pardos, mais novos e mais velhos em relação ao ensino superior presente em seus projetos profissionais. Razões e sentimentos que os movem e que se movem, nem sempre examinados em estudos sobre a matéria, foram expostos. Contribuições de Elias (1990), de R. Williams (1969), de Bourdieu (2003, 2009), de E. P. Thompson (2002), de Löwy (1990), entre outros, apoiaram evidências de que as relações indivíduo e sociedade, sempre plurais e complexas, expressam apenas partes de seus sentidos civilizadores. Para reduzir incertezas, recorreu-se a dados macrossociais e microssociais (REVEL, 1998). Entrevistas com tais jovens e coordenadores de seus cursos, observações advindas de dinâmica de grupo e, também, exame de publicações oficiais, de periódicos de divulgação de matéria sobre vestibular, entre 2009-2010, situaram um trato de escalas analíticas de difícil exercício. Para além das relações de classes, gênero, cor da pele, geração etc., pode-se concluir que esses sujeitos, por razões e sentimentos variados, com seus projetos profissionais, tanto se deslocam de suas posições sociais de origem como as mantêm, mas todos, em suas novas experiências e de diferentes modos, também se preparam para atuar sobre os sentidos civilizadores de seu tempo. / Provide clarity to the feelings and reasons that emerge from the experiences of the students in Vitória-ES, between 2009-2010, and what move them toward their professional projects is the goal of this work. The notion of design used here (Velho, 1999) differs from the classical liberal understanding of human being, autonomous, free and unique, responsible for their successes and failures, underlie to studies on "career choice". The proposed idea is that the field experiences of the subjects mark their professional projects, but their deliberate conduct, not necessarily rational, expose certain life expectations, whatever is the social position of these individuals. To test these expectations, these subjects were seen in their social relations on the intersections of class, gender, ethnicity, generations, etc. It was recognized also that the reasons and feelings (WILLIAMS, 1969) also forge professional projects of subjects under different social conditions and in spite of them. Considering that these projects carry human manifestations not always visible, often covered, the metaphor of "rhizome" (DELEUZE; GUATTARI, 2004) was useful as methodology. Evidences (GINZBURG, 2007) suggested research paths and some of the meanings attributed by those subject to these projects could be detected. The prospect of long-term historical and multiple times chaired the examination of trajectories of a selected group of subjects studied between the years 2009-2010, which favored the perception of historical continuities, but also the occurrence of certain changes in social trends. Two pre-university courses, one public and one private, in Vitória, ES, at this juncture, showed a bit of a plurality of different expectations of young people - poor, middle and upper classes, men and women, whites, blacks and browns, younger and older in relation to high school - present in their professional projects. Reasons and feelings that move them and that move is not always considered in studies on the subject, were exposed. Contributions of Elias (1990), Williams (1969), Bourdieu (2003, 2009), E. P. Thompson (2002), Löwy (1990), among others, supported evidences that the relation between individual and society, always plural and complex, express only parts of their civilizing senses. To reduce uncertainties, it was used macro and micro data (Revel, 1998). Interviews with these teenagers and advisers, observations from group dynamics and also examination of official publications, periodicals to disseminate material on vestibular, between 2009-2010, were located a tract of analytical scales difficult to exercise. Apart from relations of class, gender, skin color, generation, etc., is possible to conclude that these subjects, for reasons and various feelings, with their professional projects, move are not from their social origin, but all of them, in their new experiences and different ways, also prepare themselves to act on the senses civilizing of his time.

Entretanto, pouco se fala em utilizar essas soluções para diminuir o espaço das lojas físicas e torná-las mais eficientes. Embora haja competição entre os canais físico e digital na distribuição de produtos, existem evidências que esses canais sejam complementares, com a loja física servindo de showroom para as vendas do e-commerce na região. O objetivo dessa pesquisa é investigar a relação entre área da loja física e vendas off-line e online dentro da área de influência da loja. Para atingir esse objetivo, foi realizado um experimento de campo com os dados de venda de quatro lojas de uma rede varejista na cidade de São Paulo, em que duas dessas lojas tiveram sua área de vendas reduzida. Os resultados indicam que as mudanças na loja causaram impacto nas vendas off-line: quando houve alteração de visual merchandising simultaneamente à redução da área o impacto foi positivo, e quando a redução foi feita de forma mais simples, esse impacto foi negativo. Já nas vendas online não houve alteração: a tendência de crescimento se manteve para as duas lojas. Implicações da pesquisa incluem insights para gestores do setor sobre investimentos de expansão/redução online/off-line no contexto de multicanalidade. / This thesis is based in the multichannel retail environment, which is a recurrent theme especially after the rapid growth in e-commerce sales in recent past (12% in 2017 over 2016 in Brazil) that has contributed to the entrance of major traditional retailers in the electronic channel. In spite of that, there has been very little discussion on using these online tools to reduce store space and make it more efficient. Because even though there is some competition between the physical and digital channels in sales and distribution, evidences point that they are complementary with the store serving as showroom to the e-commerce sales in the region. The main objective of this research is to investigate the relationship between physical store size and sales both off-line and online within the region of influence of the store. To achieve this goal, a field experiment was conducted with data from four stores of a retail chain in the city of São Paulo, two of which had their sales area reduced. The results indicate that after the reduction, sales from both stores were impacted, but in the store where this reduction was made in conjunction with other changes in visual merchandising the impact was positive, while in the store where the reductions was simpler this impact was negative. In regards to the online sales, there was no measurable change in sales trend. The implications of this research include insights to managers of this sector about investments and expansion plans within this context.

Due to intense competition, retail stores are today forced to come up with exciting new sales promotional ideas to remain a relevant choice for customers. Gift giving is a sales promotional tool which has previously demonstrated to increase customer satisfaction and spending - an ideal situation for any retailer. However, gift giving has only been researched and confirmed for retailers that offer consumable goods. It has yet to be measured in a context where it is of greater difficulty for the customer to spend more than planned. This research fills that void by conducting a field experiment at a retail store offering durable shopping products.The purpose of the study is to investigate the effect gift giving has on gratitude, obligation, satisfaction, impulsive buying, and spending at a retail store offering durable shopping products. Through a field experiment, the study tests the effect on these variables of both small and large gifts and explore whether customer spending increases alongside the gift’s monetary worth.To complete the purpose of the study, a case company representing a durable shopping products retailer was selected. A field experiment was setup with two experimental groups and one control group. The results from the manipulation were collected through questionnaires which included questions pertaining to the study’s five variables. The collected data was then analysed through the statistics program SPSS.The only emotion that is affected from providing gifts in this retail environment is obligation, a negative emotion, which in turn decreases customer satisfaction. Since giving a gift only evokes negative emotions, it is concluded that a durable goods retailer should not use gift giving as a sales promotional tool. Additionally, when given a large gift, customer spending decreases considerably. This could imply that gift giving does not work in this retail environment, or that an extraneous variable affected the experiment’s outcome.

This thesis consists of four papers summarized as follows. Do Payroll Tax Cuts Raise Youth Employment? We study whether payroll tax reductions are an effective means to raise youth employment. In 2007, the Swedish employer-paid payroll tax was cut on a large scale for young workers, substantially reducing labor costs for this group. Using the variation in payroll taxes across cohorts, we estimate a significant, but small, impact both on employment and on wages. Effects of Taxes on Youth Self-Employment and Income. I examine the link between taxes and youth self-employment. I make use of a Swedish reform that made the payroll tax and the self-employment tax vary by age. The results suggest that youth self-employment is insensitive to tax reductions, both in the short run and in the somewhat longer run. For those defined as self-employed, I find positive effects on income from self-employment, and negative effects on income from wage employment. Can Indifference Make the World Greener? We conducted a natural field experiment at a large university in Sweden to evaluate the effects of two resource conservation programs. The first intervention consisted of a campaign that actively tried to convince people to cut back on printing in general, and to use double-sided printing whenever possible. The second intervention exploited people's tendency to stick with pre-set alternatives. At random points in time we changed the printers’ default settings, from single-sided to double-sided printing. Whereas the moral appeal had no impact, the default change cut paper use by 15 percent. The Origins of Behavioral Contagion: Evidence from a Field Experiment on Facebook. We explore the micro-level foundations of behavioral contagion by running a natural field experiment on the networking site Facebook. Members of Facebook express positive support to content on the website by clicking a Like button. We show that users are more prone to support content if someone else has done so before.

This thesis is composed of four self-contained papers and focuses on discrimination in themarket place. Essay 1: “Disability Discrimination in the Rental Housing Market – A Field Experiment onBlind Tenants.” Although discrimination against disabled people has been investigated inthe labor market, the housing market has received less attention in this regard. This paperfocuses on the latter market and investigates whether blind tenants assisted by guide dogsare discriminated against in the rental housing market. The data are collected through afield experiment in which written applications were sent in response to onlineadvertisements posted by different types of advertisers. I find statistically significantevidence that one type of online advertiser, that is, the apartment owner (i.e., a person whoadvertises and rents out his/her own apartment(s) on his/her own), discriminates againstblind tenants, because of the presence of the guide dog, not because of the disability.According to the legislation, this behavior qualifies as illegal discrimination. Essay 2: “Does the design of correspondence studies influence the measurement of discrimination?”(co-authored with Carlsson and Rooth). Correspondence studies can identify the extent ofdiscrimination in hiring as typically defined by the law, which includes discriminationagainst ethnic minorities and females. However, as Heckman and Siegelman (1993) show,if employers act upon a group difference in the variance of unobserved variables, thismeasure of discrimination may not be very informative. This issue has essentially beenignored in the empirical literature until the recent methodological development byNeumark (2012). We apply Neumark’s method to a number of already publishedcorrespondence studies. We find the Heckman and Siegelman critique relevant forempirical work and give suggestions on how future correspondence studies may address thiscritique. Essay 3: “Does Labor Market Tightness Affect Ethnic Discrimination in Hiring?” (co-authoredwith Carlsson and Rooth). In this study, we investigate whether ethnic discriminationdepends on labor market tightness. While ranking models predict a negative relationship,the prediction of screening models is ambiguous about the direction of the relationship.Thus, the direction of the relationship is purely an empirical issue. We utilize three (butcombine into two) correspondence studies of the Swedish labor market and two distinctlydifferent measures of labor market tightness. These different measures produce very similarresults, showing that a one percent increase in labor market tightness increases ethnicdiscrimination in hiring by 0.5-0.7 percent, which is consistent with a screening model.This result stands in sharp contrast to the only previous study on this matter, Baert et al.(forthcoming), which finds evidence that supports a ranking model. Essay 4: “Relative Age Effect on Labor Market Outcomes for High Skilled Workers – Evidencefrom Soccer.” In sports and education contexts, children are divided into age groups that arearbitrary constructions based on admission dates. This age-group system is thought todetermine differences in maturity between pupils within the same group, that is, relative904627 Luca Furmaco_inl.indd 5 2015-02-24 16:58age (RA). In turn, these within-age-group maturity differences produce performance gaps,that is, relative age effects (RAEs), which might persist and affect labor market outcomes. Ianalyze the RAE on labor market outcomes using a unique dataset of a particular group ofhigh-skilled workers: soccer players in the Italian major soccer league. In line with previousstudies, evidence on the existence of an RAE in terms of representativeness is found,meaning that players born relatively early in an age group are over-represented, whileplayers born relatively late are under-represented, even accounting for specific populationtrends. Moreover, players born relatively late in an age group receive lower gross wages thanplayers born relatively early. This wage gap seems to increase with age and in the quantileof the wage distribution.
