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.

The study aims to assess the empirical adherence of the permanent income theory and the consumption smoothing view in Latin America. Two present value models are considered, one describing household behavior and the other open economy macroeconomics. Following the methodology developed in Campbell and Schiller (1987), Bivariate Vector Autoregressions are estimated for the saving ratio and the real growth rate of income concerning the household behavior model and for the current account and the change in national cash ‡ow regarding the open economy model. The countries in the sample are considered separately in the estimation process (individual system estimation) as well as jointly (joint system estimation). Ordinary Least Squares (OLS) and Seemingly Unrelated Regressions (SURE) estimates of the coe¢cients are generated. Wald Tests are then conducted to verify if the VAR coe¢cient estimates are in conformity with those predicted by the theory. While the empirical results are sensitive to the estimation method and discount factors used, there is only weak evidence in favor of the permanent income theory and consumption smoothing view in the group of countries analyzed.

Nesse trabalho estima-se, usando o método generalizado dos momentos e dados brasileiros, os parâmetros estruturais do modelo CCAPM (consumption capital asset pricing model) a partir de três classes de funções utilidade distintas: função utilidade potência (CRRA), utilidade com hábito externo, e aversão ao desapontamento (Kreps-Porteus). Estes parâmetros estruturais estão associados à aversão ao risco, à elasticidade de substituição intertemporal no consumo e à taxa de desconto intertemporal da utilidade futura. Os resultados aqui obtidos são analisados e comparados com resultados anteriores para dados brasileiros e americanos. Adicionalmente, testa-se econometricamente todos os modelos estruturais estimados a partir do teste de restrições de sobre-identificação, para investigar, da forma mais abrangente possível, se há ou não equity premium puzzle para o Brasil. Os resultados surpreendem, dado que, em raríssimas ocasiões, se rejeita as restrições implícitas nesses modelos. Logo, conclui-se que não há equity premium puzzle para o Brasil.

Is private money feasible and desirable? In its absence, is there a central bank policy that partially or fully substitutes for private money? In this paper, some recent modeling ideas about how to address these questioned are reviewed and applied. The main ideas are that people cannot commit to future actions and that their histories are to some extent unknown - are not common knowledge. Under the additional assumption that the private monies issued by diferent people are distinct, a strong recognizability assumption, it is shown that there is a role for private money.

In this paper we revisit the relationship between the equity and the forward premium puzzles. We construct return-based stochastic discount factors under very mild assumptions and check whether they price correctly the equity and the foreign currency risk premia. We avoid log-linearizations by using moments restrictions associated with euler equations to test the capacity of our return-based stochastic discount factors to price returns on the relevant assets. Our main finding is that a pricing kernel constructed only using information on American domestic assets accounts for both domestic and international stylized facts that escape consumption based models. In particular, we fail to reject the null hypothesis that the foreign currency risk premium has zero price when the instrument is the own current value of the forward premium.

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.

Vários trabalhos sugerem que os benefícios privados podem explicar o diferencial de preços entre espécies de ações com direitos diferenciados de voto. Entretanto, no Brasil o diferencial de preço entre a ação ordinária e a ação preferencial é negativo para várias empresas no período de julho de 1994 a setembro de 2002. Este trabalho investiga os determinantes que implicam este desconto da ação ordinária em relação à ação preferencial. Em particular, o trabalho analisa os impactos da liquidez, dos dividendos diferenciados, e das recentes mudanças na legislação sobre o prêmio pelo voto. Este artigo documenta que liquidez é extremamente relevante na determinação dos preços relativos. Constatações empíricas confirmam o impacto negativo da Lei n° 9.457 revogando os direitos dos ordinaristas minoritários de venda conjunta com controlador e o impacto positivo da introdução da Lei n° 10.303, restabelecendo estes direitos aos ordinaristas. Finalmente, a estrutura de propriedade se mostrou ter uma relação positiva com o prêmio pelo voto, mas a participação do maior acionista em ações ordinárias não apresentou uma relação significativa.

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.

Este trabalho objetivou estudar o modelo de avaliação de empresas e projetos fundamentado na Teoria de Opções Reais. Foi demonstrado que, dado a existência de incertezas sobre os acontecimentos futuros e a possibilidade de os investidores modificarem suas decisões no decorrer do tempo, os modelos tradicionais de avaliação erram, pois desconsideram as modificações que a taxa de desconto utilizada sofre em função de uma decisão tomada sobre uma opção qualquer existente. Por outro lado, com a utilização da Teoria de Opções Reais é possível identificar estas opções e avaliá-las de forma correta. Apresentou-se um exemplo em que determinado investimento foi avaliado pelo modelo de Desconto dos Fluxos de Caixa e pela Teoria de Opções Reais, o qual demonstrou que os modelos tradicionais erram ao não considerar e valorar as opções reais existentes, confirmando desta forma a proposição inicial do trabalho.

Este trabalho propõe maneiras alternativas para a estimação consistente de uma medida abstrata, crucial para o estudo de decisões intertemporais, o qual é central a grande parte dos estudos em macroeconomia e finanças: o Fator Estocástico de Descontos (SDF, sigla em Inglês). Pelo emprego da Equação de Apreçamento constrói-se um inédito estimador consistente do SDF que depende do fato de que seu logaritmo é comum a todos os ativos de uma economia. O estimador resultante é muito simples de se calcular, não depende de fortes hipóteses econômicas, é adequado ao teste de diversas especificações de preferência e para a investigação de paradoxos de substituição intertemporal, e pode ser usado como base para a construção de um estimador para a taxa livre de risco. Alternativas para a estratégia de identificação são aplicadas e um paralelo entre elas e estratégias de outras metodologias é traçado. Adicionando estrutura ao ambiente inicial, são apresentadas duas situações onde a distribuição assintótica pode ser derivada. Finalmente, as metodologias propostas são aplicadas a conjuntos de dados dos EUA e do Brasil. Especificações de preferência usualmente empregadas na literatura, bem como uma classe de preferências dependentes do estado, são testadas. Os resultados são particularmente interessantes para a economia americana. A aplicação de teste formais não rejeita especificações de preferências comuns na literatura e estimativas para o coeficiente relativo de aversão ao risco se encontram entre 1 e 2, e são estatisticamente indistinguíveis de 1. Adicionalmente, para a classe de preferência s dependentes do estado, trajetórias altamente dinâmicas são estimadas para a tal coeficiente, as trajetórias são confinadas ao intervalo [1,15, 2,05] e se rejeita a hipótese de uma trajetória constante.

Leilão é um procedimento de alocação de recursos com boas propriedades. Apresento a literatura teórica de leilões a qual demonstra, que sob diversas condições, leilões levam à alocação eficiente de recursos e maximização da receita do leiloeiro. Entretanto estes resultados valem apenas se os participantes do leilão não estejam organizados em cartéis. Um Cartel é uma organização que inibe a concorrência entre firmas. A atuação de um cartel pode ou não levar a uma alocação eficiente de recursos, mas a receita do leiloeiro será sempre prejudicada. Analiso a literatura teórica de cartel em leilões de objeto único que caracteriza formas de coordenação do cartel, estratégias de atuação e sua sustentabilidade. Apresento os desafios que o cartel deve superar. Mais ainda, proponho medidas que devem ser tomadas, caso haja suspeita de existência de cartel. O leilão de primeiro preço é o menos suscetível a ação de cartéis, pois nele há incentivo para as firmas desviarem das orientações do cartel. O combate a cartéis é avaliado por meio da taxa de desconto necessária para o cartel existir. Se a taxa de desconto necessária é menor significa um cartel mais difícil de ser sustentado. Demonstro que o preço de reserva randômico é melhor para combater cartéis do que o preço de reserva fixo em leilões de primeiro preço que se repetem.

Quando as empresas decidem se devem ou não investir em determinado projeto de investimentos a longo prazo (horizonte de 5 a 10 anos), algumas metodologias alternativas ao Fluxo de Caixa Descontado (FCD) podem se tornar úteis tanto para confirmar a viabilidade do negócio como para indicar o melhor momento para iniciar o Empreendimento. As análises que levam em conta a incerteza dos fluxos de caixa futuros e flexibilidade na data de início do projeto podem ser construídos com a abordagem estocástica, usando metodologias como a solução de equações diferenciais que descrevem o movimento browniano. Sob determinadas condições, as oportunidades de investimentos em projetos podem ser tratados como se fossem opções reais de compra, sem data de vencimento, como no modelo proposto por McDonald-Siegel (1986), para a tomada de decisões e momento ótimo para o investimento. Este trabalho analisa a viabilidade de investimentos no mercado de telecomunicações usando modelos não determinísticos, onde a variável mais relevante é a dispersão dos retornos, ou seja, que a variância representa o risco associado a determinado empreendimento.

Consumption is an important macroeconomic aggregate, being about 70% of GNP. Finding sub-optimal behavior in consumption decisions casts a serious doubt on whether optimizing behavior is applicable on an economy-wide scale, which, in turn, challenge whether it is applicable at all. This paper has several contributions to the literature on consumption optimality. First, we provide a new result on the basic rule-of-thumb regression, showing that it is observational equivalent to the one obtained in a well known optimizing real-business-cycle model. Second, for rule-of-thumb tests based on the Asset-Pricing Equation, we show that the omission of the higher-order term in the log-linear approximation yields inconsistent estimates when lagged observables are used as instruments. However, these are exactly the instruments that have been traditionally used in this literature. Third, we show that nonlinear estimation of a system of N Asset-Pricing Equations can be done efficiently even if the number of asset returns (N) is high vis-a-vis the number of time-series observations (T). We argue that efficiency can be restored by aggregating returns into a single measure that fully captures intertemporal substitution. Indeed, we show that there is no reason why return aggregation cannot be performed in the nonlinear setting of the Pricing Equation, since the latter is a linear function of individual returns. This forms the basis of a new test of rule-of-thumb behavior, which can be viewed as testing for the importance of rule-of-thumb consumers when the optimizing agent holds an equally-weighted portfolio or a weighted portfolio of traded assets. Using our setup, we find no signs of either rule-of-thumb behavior for U.S. consumers or of habit-formation in consumption decisions in econometric tests. Indeed, we show that the simple representative agent model with a CRRA utility is able to explain the time series data on consumption and aggregate returns. There, the intertemporal discount factor is significant and ranges from 0.956 to 0.969 while the relative risk-aversion coefficient is precisely estimated ranging from 0.829 to 1.126. There is no evidence of rejection in over-identifying-restriction tests.

We build a pricing kernel using only US domestic assets data and check whether it accounts for foreign markets stylized facts that escape consumption based models. By interpreting our stochastic discount factor as the projection of a pricing kernel from a fully specified model in the space of returns, our results indicate that a model that accounts for the behavior of domestic assets goes a long way toward accounting for the behavior of foreign assets. We address predictability issues associated with the forward premium puzzle by: i) using instruments that are known to forecast excess returns in the moments restrictions associated with Euler equations, and; ii) by pricing Lustig and Verdelhan (2007)'s foreign currency portfolios. Our results indicate that the relevant state variables that explain foreign-currency market asset prices are also the driving forces behind U.S. domestic assets behavior.

Lucas (1987) has shown a surprising result in business-cycle research, that the welfare cost of business cycles are relatively small. Using standard assumptions on preferences and a reasonable reduced form for consumption, we computed these welfare costs for the pre- and post-WWII era, using three alternative trend-cycle decomposition methods. The post-WWII period is very era this basic result is dramatically altered. For the Beveridge and Nelson decomposition, and reasonable preference parameter and discount values, we get a compensation of about 5% of consumption, which is by all means a sizable welfare cost (about US$ 1,000.00 a year).
