The development of large discount retailers, or big-boxes as they are sometimes referred to, are often subject to heated debate and their entry on a market is greeted with either great enthusiasm or dread. For instance, the world’s largest retailer Wal-Mart (Forbes 2014) has a number of anti- and pro-groups dedicated to its being and the event of a Wal-Mart entry tends to be met with protests and campaigns (Decamme 2013) but also welcomed by, for instance, consumers (Davis & DeBonis 2013). Also in Sweden, the entry of a big box is a hot topic and before IKEA’s opening i Borlänge 2013, the first in Sweden in more than five years, great expectations were mixed with worry (Västerbottens-Kuriren 2011).The presence of large scale discount retailers is not, however, a novel phenomenon but a part of a long-term change in retailing that has taken place globally over the past couple of decades (Taylor & Smalling, 2005). As noted by Dawson (2006), the trend in Europe has over the past few decades gone towards an increasing concentration of large firms along with a decrease of smaller firms.This trend is also detectable in the Swedish retail industry. Over the past decade, the retailing industry in Sweden has increased by around 190 Billion SEK, and its share of GDP has risen from 2,7% to 2,9%, while the number of employees have increased from 200 000 to 250 000 (HUI 2013). This growth, however, has not been distributed evenly but rather it has been oriented mainly towards out-of-town retail clusters. Parallel to this development, the number of large retailers has risen at the expense of market shares of smaller independent firms (Rämme et al 2010). Thereby, the presence of large scale retailers is simply part of a changing retail landscape.The effects of this development, where large scale retailing agents relocate shopping to out-of-town shopping areas, have been heavily debated. On the one hand, the big-boxes are accused of displacing independent small retail businesses in the city-centers and the residential areas, resulting in, to some extent, reduced employment opportunities and less availability for the consumers - especially the elderly (Ljungberg et al 2006). In addition, as access to shopping now tends to require some sort of a motorized vehicle, environmental aspects to the discussion have emerged. Ultimately these types of concerns have resulted in calls for regulations against this development (Olsson 2010). On the other hand, the proponents of the new shopping landscape argue that this evolution implies productivity gains, the benefits of lower prices and an increased variety of products (Maican & Orth 2012). Moreover it is argued that it leads to, for instance, better services (such as longer opening hours) and a creative destruction transformation pressure on retailers, which brings about a renewal of city-centerIIretail and services, increasing their attractivity (Bergström 2010). The belief in benefits of a big box entry can be exemplified by the attractivity of IKEA, and the fact that municipalities are prepared to commit to expenses amounting up to hundreds of millions in order to attract the entry of this big-box. Borlänge municipality, for instance, agreed to expenses of about 350 million SEK in order to secure the entry of IKEA, which opened in 2013 (Blomgren 2009).Against this backdrop, the overall effects of large discount retailers become important: Are the economic benefits enough to warrant subsidies or are there, on the contrary, some very compelling grounds for regulations against these types of establishments? In other words; how is overall retail in a region where a store like IKEA enters affected? And how are local retail firms affected?In order to answer these questions, the purpose of this thesis is to study how entry of a big-box retailer affects the entry region. The object of this study is IKEA - one of the world’s largest retailers, with 345 stores, active in over 40 countries and with profits of about 3.3 billion (IKEA 2013; IKEA 2014). By studying the effects of IKEA-entry, both on an aggregated level and on firm level, this thesis intends to find indications of how large discount retail establishments in general can be expected to affect the economic development both in a region overall, but also on the local firm level, something which is of interest to both policymakers as well as the retailing industry in general.The first paper examines the effects of IKEA on retail revenues and employment in the municipalities that IKEA chose to enter between 2000 and 2011; Gothenburg, Haparanda, Kalmar and Karlstad. By means of a matching method we first identify non-entry municipalities that have a similar probability of IKEA entry as the true entry municipalities. Then, using these non-entry municipalities as a control group, the causal effects of IKEA entry can be estimated using a treatment-control approach. We also extend the analysis to examine the spatial impact of IKEA by estimating the effects on retail in neighboring municipalities. It is found that a new IKEA store increases revenues in durable goods trade with 20% in the entry municipality and the number of employees with 17%. Only small, and in most cases statistically insignificant, negative effects were found in neighboring municipalities.It appears that there is a positive net effect on durables retail sales and employment in the entry municipality. However, the analysis is based on data on an aggregated municipality level and thereby it remains unclear if and how the effects vary within the entry municipalities. In addition, the data used in the first study includes the sales and employment of IKEA itself, which could account for the majority of the increases in employment and retail. Thereby the potential spillover effects on incumbent retailers in the entry municipalities cannot be discerned in the first study.IIITo examine effects of IKEA entry on incumbent retail firms, the second paper in this thesis analyses how IKEA entry affects the revenues and employment of local retail firms in three municipalities; Haparanda, Kalmar and Karlstad, which experienced entry by IKEA between 2000 and 2010. In this second study, we exclude Gothenburg due to the fact that big-box entry appears to have weaker effects in metropolitan areas (as indicated by Artz & Stone 2006). By excluding Gothenburg we aim to reduce the geographical heterogeneity in our study. We obtain control municipalities that are as similar as possible to the three entry municipalities using the same method as in the previous study, but including a slightly different set of variables in the selection equation. Using similar retail firms in the control municipalities as our comparison group, we estimate the impact of IKEA entry on revenues and employment for retail firms located at varying distances from the IKEA entry site.The results generated in this study imply that entry by IKEA increases revenues in incumbent retail firms by, on average, 11% in the entry municipalities. In addition, we do not find any significant impact on retail revenues in the city centers of the entry municipalities. However, we do find that retail firms within 1 km of the IKEA experience increases in revenues of about 26%, which indicates large spillover effects in the area nearby the entry site. As expected, this impact decreases as we expand the buffer zone: firms located between 0-2 km experiences a 14% increase and firms in 2-5 km experiences an increase of 10%. We do not find any significant impacts on retail employment.

Sociology, hybrids and social reality: the case of nuclear waste The continuing technological transformation of nature means that sociology’s traditional vision of a sharp divide between nature and society is becoming ever harder to defend. Starting from Bruno Latour’s critique of modernity, and Nikolas Rose’s explorations of political power beyond the state, this article presents a framework for analysing the expanding wealth of hybrids of nature and society surrounding us today, and the problems of government they pose. These hybrids confront us with the need to rethink sociology’s conception of ‘the social’. With Latour’s help, the interplay of nature and society can be understood as subject to technical mediation, opening the way for studies of the varying arrangements through which different configurations of nature and society are produced. Rather than alternative social constructions of nature, what sociologists should be at pains to analyse and question are different programmes and strategies for bringing together natural and social forces in durable combinations. In the article, the geological disposal of nuclear waste serves as a useful example for exploring the fruitfulness of the analytical framework put forward. This complex undertaking constitutes just one component in a larger field of technoscientific endeavour that has irrevocably transformed nature while simultaneously re-making society. Addressing this case, we seek to reveal the promise of a sociology that does not bound ‘the social’ in advance, but rather makes the co-production of technology and society one of its most important objects of study.

Ce mémoire est constitué par une analyse écocritique du roman Naissance d'un pont, écrit par Maylis de Kerangal. Le but général du mémoire est d'examiner comment ce roman décrit la relation entre l'homme et la nature. Nous examinons surtout les stratégies narratives employées par l'auteure pour transmettre l'image de cette relation et en plus, nous discutons le rôle joué par les différents paysages se retrouvant dans le récit. Finalement, l'analyse comprend aussi une brève réflexion sur la capacité éventuelle du roman d'influencer l'attitude du lecteur envers l'écologie. L'analyse des stratégies narratives se concentre sur le rôle du narrateur, ainsi que sur la présence et la fonction des perspectives éthiques, des noms symboliques et des figures de style. Ces stratégies contribuent à dépeindre une variété d'idées par rapport aux modes de vie de la société humaine, alors que les descriptions des paysages démontrent la relation complexe entre cette société et les paysages naturels et construits respectivement. Naissance d'un pont semble promouvoir une attitude à l'égard de la nature qui est plus humble que celle dominant dans la société moderne. Afin de pouvoir juger la capacité du roman de transmettre ces valeurs au lecteur, il serait pourtant raisonnable de tenir compte de plusieurs facteurs, tels que la complexité du langage et le niveau de crédibilité de l'histoire.

Transportation is seen as one of the major sources of CO2 pollutants nowadays. The impact of increased transport in retailing should not be underestimated. Most previous studies have focused on transportation and underlying trips, in general, while very few studies have addressed the specific affects that, for instance, intra-city shopping trips generate. Furthermore, most of the existing methods used to estimate emission are based on macro-data designed to generate national or regional inventory projections. There is a lack of studies using micro-data based methods that are able to distinguish between driver behaviour and the locational effects induced by shopping trips, which is an important precondition for energy efficient urban planning. The aim of this study is to implement a micro-data method to estimate and compare CO2 emission induced by intra-urban car travelling to a retail destination of durable goods (DG), and non-durable goods (NDG). We estimate the emissions from aspects of travel behaviour and store location. The study is conducted by means of a case study in the city of Borlänge, where GPS tracking data on intra-urban car travel is collected from 250 households. We find that a behavioural change during a trip towards a CO2 optimal travelling by car has the potential to decrease emission to 36% (DG), and to 25% (NDG) of the emissions induced by car-travelling shopping trips today. There is also a potential of reducing CO2 emissions induced by intra-urban shopping trips due to poor location by 54%, and if the consumer selected the closest of 8 existing stores, the CO2 emissions would be reduced by 37% of the current emission induced by NDG shopping trips.

The notification service is the part of myGrid that enables asynchronous delivery of messages between distributed components. It includes features such as topic-based publish-subscribe messaging, push/pull models, asynchronous delivery, persistence, transient and durable subscriptions, durable topics, negotiation of QoS, hierarchical topic structure and federation of services. Some of these features are novel in the area of messaging middleware. A cost evaluation of some of these features indicate that the overhead incurred is justified in terms of compensating benefits gained.

Consider an economy where infinite-lived agents trade assets collateralized by durable goods. We obtain results that rule out bubbles when the additional endowments of durable goods are uniformly bounded away from zero, regardless of whether the asset’s net supply is positive or zero. However, bubbles may occur, even for state-price processes that generate finite present value of aggregate wealth. First, under complete markets, if the net supply is being endogenously reduced to zero as a result of collateral repossession. Secondly, under incomplete markets, for a persistent positive net supply, under the general conditions guaranteeing existence of equilibrium. Examples of monetary equilibria are provided.

The paper, first, summarizes Latin American structuralism, and offers reasons why it was so influential and durable in the region, as it attended to real demands, and was part of 1950s’mainstream economics. Second, says why, with 1980s’Great Crisis, structuralism eventually ended itself into crisis, as it was unable to keep pace with historical new facts, particularly with the industrial revolution or takeoff, that made Latin American economies intermediary, still developing, but fully capitalist. Third, it lists the consensus that today exists on economic development. Forth, opposes “official orthodoxy” to “developmental populism”, the former deriving from neoclassical economics, the later from structuralism, and offers, in relation to six strategic issues, a progressive development alternative.

I use Search models to study decentralized markets of durable goods. I explore the concept of market liquidity of Lippman and McCall (1986) and show that the theory of optimal search is useful to address the following issues: What governs the time required to make a transaction on these markets? What is the relationship between the price of goods and the time required to make transactions? Why is optimal to wait to make a transaction in markets where individuals discount future utility? What is the socially optima search level? Two specifications are used, the traditional model of job search and a version of Krainer and LeRoy (2001) model.

Esta pesquisa pretende analisar o Governo Geisel e o II Plano Nacional de Desenvolvimento, verificando se essa política econômica representou a implantação de um novo padrão de acumulação no Brasil ou se trata de uma fase mais avançada do padrão de acumulação de bens duráveis que vigorava no País com os planos anteriores. O II PND aumentou ou diminuiu a dependência brasileira no contexto internacional? Esse plano é tão heterodoxo quanto o I PND ou representa uma guinada ortodoxa? Qual foi o papel e o peso dos gestores econômicos no Governo Geisel?

É nítida e rápida a popularização da maioria dos bens duráveis de consumo no Estado de São Paulo, nos últimos vinte anos. Colaboram para isso a universalização da oferta domiciliar de eletricidade, água encanada, esgotos, e a tendência ao barateamento dos bens. Entre outros efeitos, tal popularização deteriora a eficácia das escalas de classificação sócio- econômica baseadas na posse de itens de conforto doméstico, suscitando freqüentes revisões e discórdias no interior da comunidade de marketing. Este estudo sistematiza estatísticas sobre situação domiciliar e posse de itens de conforto doméstico no Estado de S. Paulo, e mostra como isso afeta o consumo material e cultural. Finalmente, aponta que é chegada a hora de se usar mais e melhor variáveis como educação, profissão, qualidade do domicílio, tal como se faz em países desenvolvidos, para o entendimento mais pleno das mudanças que implantam no Brasil a moderna sociedade de consumo.

o presente estudo de caso investiga, empiricamente, a rentabilidade associada aos consumidores do varejo eletrônico de bens duráveis no Brasil. Para tal, o arcabouço teórico baseia-se em teorias rivais, notadamente as expostas na literatura tradicional do Marketing de Relacionamento - que discute os beneficios da retenção de clientes - e nas recentes publicações que questionam tal abordagem - argumentando que os consumidores esporádicos podem se mostrar mais valiosos que os freqüentes. Nas duas empresas investigadas, os clientes esporádicos demonstram-se mais rentáveis que os freqüentes. Entretanto, a análise exploratória dos dados qualitativos demonstra que ambas utilizam abordagens transacionais para interagir com os consumidores. O cruzamento das evidências quali-quantitativas sugere que o declínio do valor dos clientes freqüentes está associado a práticas gerenciais que não se encontram em conformidade com a literatura convencional de marketing. Por conseguinte, as evidências quantitativas parecem não representar anomalias perante a teoria vigente, segundo a qual os beneficios inerentes à retenção de consumidores fazem sentido apenas para as empresas que estiverem orientadas a clientes e puderem interagir de forma relacional com os mesmos. O estudo possibilita supor que o valor dos clientes está associado à forma como as empresas se relacionam com o mercado. A adoção de práticas transacionais, a baixa diferenciação e a competição baseada em descontos parece potencializar a sensibilidade ao preço por parte dos consumidores, principalmente daqueles mais freqüentemente.

Deep Changes in the consuming market are demanding a high level of competitive skills from all kind of companies, mainly those directed to sales of consumer goods. How to engage customers is a key factor, a competitive skill, to be learned from successful practices. This Master dissertation is concentrated on the case of a department store, a successful branch of an organization called Quero-Quero, in south of Brazil. Observations, interviews, and a survey, and its analysis, lead to the identification of informal practices and instruments they use to establish durable links with customers. Also the role of all stakeholders is considered both in the survey and analysis.

Access has been one of the main difficulties companies have faced in emerging markets (PRAHALAD, 2005). The capillarity of the market, the existence of small, not professionalized and sometimes informal retailers, the lack of infrastructure and high transportation costs are some of the distribution challenges companies face in poorer regions. The literature concerning the Base of the Pyramid (BoP) is still recent and only after the seminal article by Prahalad and Hart (2002), it evolved into many different management perspectives. However, there is a lack of researches concerning distribution strategies to the BoP. Therefore, the main objective of this research is to identify, in the perception of executives working in the market, the conditions associated to a satisfactory distribution for the BoP market in Brazil and to build a substantive theory that helps to shed light to the understanding of the distribution phenomenon adopted by consumer goods companies to reach the BoP market in Brazil. In order to accomplish the objectives of this thesis, a grounded theory methodology (Glaser; Strauss, 1967; Corbin; Strauss, 2008) was used. This approach helped to identify the channel strategies used by local and global companies in the market. Many techniques for data collection were applied. The most important one was in-depth interviews with 26 executives from 24 different consumer goods companies in Brazil. Among the companies there were small, medium and large enterprises; which were also grouped as manufacturers, distributors and retailers. Furthermore, secondary data were examined to identify business strategies to reach BoP and map global distribution initiatives. A database from a consumer panel was also used to analyze what and where BoP consumers purchase non-durable goods. It was verified that small and traditional retailing is a very strong format in BoP markets and in the Northern/Northeastern regions. Cash & Carry is a format that is growing a lot. On the other hand, hypermarkets are not very used by low income population. The results suggest that three major categories are associated to a satisfactory distribution: (a) willingness, which means the effort, knowledge and enthusiasm a firm has to operate at BoP markets; (b) well-done execution, which is related to designing correctly the marketing channel and operating efficiently in an environment full of obstacles, such as lack of infrastructure, capillarity, lack of safety, regional differences and informality, and (c) relationship, which was perceived to be friendlier and essential at BoP markets, since it is very difficult for manufacturers to reach the entire market alone. It is more likely to have a satisfactory distribution when manufacturers establish strong relationships in the marketing channel. Besides, small retailers have a perception of isolation and expect a higher level of relationship. These major categories explain also the competitive advantage that local companies have in relation to MNCs and large companies. Despite of the limitations of an exploratory study, it is expected that this thesis will contribute to the BoP knowledge as well as to the identification of the peculiarities of distribution in BoP markets.

A história recente do Nordeste caracteriza-se por uma primeira fase de isolamento e outra de articulação. Nessa segunda fase, o dinamismo que se instala a partir da década de sessenta provocou profundas transformações na economia da região. Essas transformações implicaram em elevadas taxas de expansão do produto regional, alterações na estrutura produtiva através da adoção de novos processos de trabalho que implicou de um lado, na redução da demanda por trabalho e de outro, na sua expansão. Registrou-se, também, mudanças bastante significativas nos gêneros industriais reduzindo a participação na produção das indústrias de bens de consumo não-duráveis e aumentando de modo importante a participação das indústrias de bens intermediários voltadas para o mercado nacional e internacional, o que contribui para aumentar a dependência do Nordeste em relação as regiões mais ricas. As mudanças iniciadas no setor industrial se propagam para os setores primários, secundários e terciários. No setor agrícola, as transformações dificultaram a sobrevivência do trabalhador, ampliaram as relações capitalistas no setor manifestas na maior proletarização da mão-de-obra rural; estimularam as emigrações para. as cidades e elevaram consideravelmente a participação da população ocupada em atividades predominantemente urbanas. No setor terciário, as mudanças provocaram o incremento do subemprego, grande diferenciação nos 11 níveis de produtividade e rendimentos, gerando um quadro de aprofundamento da heterogeneidadeda estrutura produtiva e do mercado de trabalho. Adicionalmente, houve uma excessiva urbanização, aumento da concentração da renda, incremento do grau de informalidade, crescimento do número de empregados clandestinos e maior participação dos menores e adultos no mercado de trabalho. Tudo isso, ocorreu,associado ao quadro de dinamismo das atividades produtivas, sem paralelo na história recente das regiões atrasadas do pais. A análise dos dados também mostrou que o nível do desemprego aberto, é relativamente baixo tanto para os homens como para as mulheres. Isto ocorre porque na expansão ou na retração econômica as flutuações no nível de ocupação são acampanhadas por modificações da taxa de participação da PIA no mercado de trabalho. Portanto, a recente infonnalidade, fonnalidade e submersão da mão-de-obra no Nordeste estão associadas a um contexto de crescimento da economia e, por conseguinte, resultam do estilo ou padrão de acumulação de capital que, mesmo se realizando com altas taxas de expansão, não repercute positivamente no mercado de trabalho, nos tennos requeridos pela oferta de mão-de-obra. Assim, o aparecimento de um excedente relativo de população é resultado do padrão de acumulação da capital da economia regional, que está associado ao modo como o Nordeste se inseriu no contexto nacional e, nesse sentido, é o padrão de industrialização o principal fator responsável por parte importante do insucesso da economia local em absorver produtivamente a população que se apresenta no mercado de trabalho urbano
