This thesis consists of four self-contained studies in empirical labor economics. Micro data on both employers and workers are used to analyze the questions asked in the essays. By using disaggregated information, issues related to firm and individual heterogeneity can be studied.The first essay, The Impact of Temporary Contracts on Gross Job and Worker Flows (with Mahmood Arai), examines job and worker flow dynamics for temporary and permanent contracts. The micro approach to job flows concerns changes in employment at the plant or firm level. Data used in earlier research on gross labor flows do not allow for a distinction between different types of employment contracts (an exception is Abowd et al. (1999). This distinction is especially important in Europe since several European countries discriminate between permanent and temporary contracts in their employment legislation.The data contain quarterly information on the stock of permanent and temporary contracts, as well as direct information on hires and separations for permanent and temporary workers. The information is from a representative sample of around 10,000 Swedish private establishments.The results indicate that temporary contracts, covering only around 10 percent of all contracts, stand for half of all gross job (and worker) flows. This means that gross job (and worker) flow rates for temporary contracts are around 10 times larger than job (and worker) flows for permanent contracts. Our results imply that job reallocation associated with temporary contracts is acyclical in both manufacturing and non-manufacturing sectors. For permanent contracts, job reallocation only exhibits a countercyclical pattern in manufacturing, characterized by a low fraction of temporary contracts. Services employing a higher fraction of temporary contracts exhibit no cyclical pattern in job reallocation, implying that establishments in services use temporary contracts as an adjustment buffer and can adjust its labor input more smoothly.The share of temporary contracts varies with the industry structure and changes as a result of sectoral shifts. This implies that cross-country comparisons, as well as studies of the dynamics of job and worker flows, based on aggregated time-series data, can be distorted by the impact of the fraction of temporary labor on gross labor flows. This, in turn, makes the distinction between permanent and temporary contracts crucial in analyzing job and worker flows, especially when labor protection laws discriminate between short-and long-term employment contracts. The second essay, Wage Dispersion and Allocation of Jobs, investigates the relationship between job turnover and the distribution of wages. One possible explanation for similar labor reallocation rates across labor markets with very different employment-protection legislations is related to differences in wage setting institutions. Bertola and Rogerson (1997) argue that although job-security laws lead to lower job flows, their impact might be reduced if differences in wage-setting institutions have opposite effects. Bertola and Rogerson’s conclusion is that when labor protection laws and wages are jointly considered, the result might very well be that job flows in countries with high adjustment costs and a compressed wage structure mimic those in countries with low adjustment costs and decentralized wages.Using establishment data on job turnover and wages for a panel of around 10,000 establishments in the Swedish private sector, the relationship between wage compression and job reallocation is studied at the industry level.Estimating industry fixed-effects models for 14 two-digit industries yield results indicating large sector differences regarding the effect of the degree of wage dispersion on job reallocation. In accordance with the Bertola and Rogerson hypothesis, this effect is positive in the manufacturing sector. Running separate regressions for job creation and job destruction shows a negative and significant effect of wage dispersion on job destruction, whereas it is insignificant in the job-creation equation. These results are in accordance with wages being more rigid downwards than upwards. The quantitative effect of the impact of wage dispersion on job turnover is limited, however. A one standard deviation increase in wage dispersion reduces the total job reallocation by around 10 percent. Turning to the non-manufacturing sector, the Bertola and Rogerson hypothesis is not supported.Further results include (i) a strong positive effect of the industry-share of temporary employees on job reallocation and (ii) a negative relationship between the use of overtime and job turnover.In the third essay, Wages, Profits and Individual Unemployment Risk: Evidence from Matched Worker-Firm Data (with Mahmood Arai), the impact of firm performance on individual wages is studied. Several studies have found a positive and significant effect of profits on wages. The most widely suggested interpretation for this phenomenon is that employers and employees engage in rent-sharing, thereby splitting the profits created between themselves.The purpose of this study is to examine the extent of rent-sharing and the impact of individual and aggregated unemployment risk on wages of individual workers. We use a sample of over 170,000 Swedish employees for 1991 and 1995 matched with their employing firm’s profits and the unemployment registers. The matched data contain detailed information on individual characteristics, including their unemployment experience during 1992-1995 as well as annual profits as reported in the firms’ balance-sheet reports.The contribution of this paper is that it provides evidence on the wage determination, based on disaggregated individual and firm data dealing with the problems of firm and worker heterogeneity, and the endogeneity of profits. Our results imply positive effects of profits on wages, both in 1991 and 1995. The reported elasticities imply that the wage inequality in Sweden due to the spread in profits is as high as 13% of the mean wages in 1991, according to Lester’s range of pay. These correlations are robust for controlling for time-invariant unobserved individual- and firm characteristics.Using firm-reported short-term product market elasticity and the number of competitors as instruments for profits suggest Lester’s measure of wage inequality due to profits to be as high as 50% of the mean wages.Finally, we investigate the impact of individual heterogeneity with respect to unemployment risk that might also affect wages. We include the individuals’ unemployment event record in our regressions, and our results confirm that individuals with a higher unemployment risk also have lower wages. Including aggregated measures along with individual unemployment risk in our estimations show results suggesting that there exists a robust negative correlation between unemployment risk and wages at various aggregation levels.The final essay, Pay Inequality and Firm Performance: Evidence from Matched Employer-Employee Data, tests several implications from tournament models on the same matched employer-employee data set as in essay 3.According to a variety of theories, the wage distribution both within and between firms can have important effects on individual productivity and firm performance. One argument for high wage differentials, based on incentive effects, is found in Lazear and Rosen’s (1981) tournament theory. Higher wage differentials lead to higher individual effort, and are therefore productivity enhancing. This, in turn, suggests that there is a positive relationship between wage dispersion and productivity. The opposite relationship is found in theories stressing fairness and cooperation between co-workers.For white-collar workers, the results show a positive effect of intra-firm pay spread on firm performance for 1991 and 1995. This applies to different measures of wage dispersion, capturing both raw differences and differences corrected for the fact that part of the wage spread is due to differences in human capital accumulation. To take firm heterogeneity into account, difference equations are estimated on a panel of firms. Once more, consistent with tournament theory, a positive and significant effect of wage dispersion on profits is found. The results for managers are based on information on about 10,000 managers. For various measures of wage dispersion and specifications, a positive and significant association between managerial pay and profits is found. No support is found for the hypothesis of a positive relationship between the number of managers (contestants) and wage spread. Instead, the results show a negative and significant effect of the number of executives and pay spread among managers.Finally, consistent with tournament theory, higher wage dispersion is found in firms operating in volatile product markets characterized by a high degree of output uncertainty. / Diss.

The preservation of agricultural land, especially that which lies close to cities (in the so-called urban fringe), is a concern in many jurisdictions around the world. Agricultural land values change dramatically as farmland is located nearer to urban areas and development pressure has increased on these lands as urban populations have expanded. In British Columbia, Canada, a provincial-wide zoning system forbids the development or non-agricultural use of land without special permission. This system is explicitly designed to protect the capability of the land to produce food in the future, but it also implicitly protects the positive spillovers from agricultural land such as environmental services and open space. Three empirical papers comprise the original research in this dissertation. They seek to answer related questions about agricultural land values in the urban fringe. First, a statistical investigation is conducted into the factors that are associated with successful applications for exclusion from the agricultural zoning system. This study finds that a measure of distance (metres from the main highway) is highly significantly correlated with a parcel’s chances of being excluded. Next, a paper examines the trend of hobby farmers springing up in the urban fringe. Two different models seek to illuminate common trends in the types of parcels that hobby farmers choose, and the price that hobby farmers pay for the land, respectively. This study finds that hobby farmers seem to be very selective about the parcels they choose, likely trying to take advantage of favourable taxation rates for agricultural producers in place in the province. Lastly, a study seeks to understand how residential parcels’ values are influenced by the nearness to and view of agricultural land. Agricultural land in the study does not appear to exhibit an open space premium, though this could be influenced by uncertainty about the future use of the land. All the empirical work in this dissertation utilizes geographic information systems (GIS) technology that allows the calculation of distances to features of interest. Hedonic pricing models and binary choice models are the main statistical tools used.

Local public authorities have signed contracts for the transfer of resources for social work implementation to only 53% of the housing states of this program (MAGALHÃES, 2016), and for an even smaller percentage there was some reimbursement for the SW executed. We verified that this low effectiveness is related to the difficulty of the professionals in municipalities to initiate and to conclude the process of contracting the service. In analyzing the objectives of Social Work as expressed in its statute (Concierge 21 of 2014 of the Ministry of Cities), we verified that the objectives, as described, make it difficult to plan actions and their evaluation, and favors low efficiency in the use of public resources. To situate our analysis historically, we introduce federal social housing policies in Brazil that preceded the My Home My Life Program, with special focus on the actions that are part of these policies aimed at helping families adapt to the new housing and their social development. We also analyze the social housing policies in the five European countries with the largest number of these types of housing policies and found that in these countries social housing is identified as affordable rental housing. We also examine the social rental experiences of the Housing Company of Johannesburg and the City of São Paulo, and discussed aspects of the relative lack of social home rental in Brazil. We conclude that social housing policies, neutral ownership, that is, without the promise of sale, allow a better social mix and help avoid processes of gentrification and spatial segregation. / Este trabalho faz uma análise da implementação do Trabalho Social (TS) no Programa Minha Casa Minha Vida-Fundo de Arrendamento Residencial (PMCMV-FAR) a partir do Quadro Conceitual do Processo de Implementação proposto por Sabatier e Mazmanian (1995). Para apenas 53% dos empreendimentos desse programa há convênios de repasse de recursos, assinados pelo poder público local, para execução do TS (MAGALHÃES, 2016), e para uma porcentagem ainda menor houve algum reembolso pelo TS executado. Verificamos que esta baixa efetividade está relacionada com a dificuldade dos profissionais das prefeituras iniciarem e concluírem o processo de contratação do serviço. Ao analisar os objetivos do TS expressos no seu estatuto (Portaria 21 de 2014 do Ministério das Cidades), verificamos que os objetivos, da forma como estão descritos, dificultam o planejamento de ações e sua avaliação, bem como favorecem a baixa eficiência no uso dos recursos públicos. Para situar nossa análise historicamente, fizemos um resgate das políticas federais de habitação social no Brasil até o Programa Minha Casa Minha Vida (PMCMV), com especial foco nas ações integrantes dessas políticas direcionadas a auxiliar na adaptação das famílias ao novo morar e promover seu desenvolvimento socioeconômico. Pesquisamos também as políticas de habitação social nos cinco países europeus com o maior número desse tipo de moradia e constatamos que nesses países a habitação social é identificada como moradias alugadas a preços módicos. Buscamos também as experiências de aluguel social da Companhia de Habitação de Johanesburgo e da Prefeitura de São Paulo e discutimos alguns aspectos da relativa falta de aluguel social no Brasil. Concluímos que políticas de habitação social, de posse neutra, ou seja, sem a promessa de venda, permitem uma melhor mistura social e ajudam a evitar processos de gentrificação e segregação espacial.

This affected the economy in two ways: first the state initiated a wave of privatization in the wake of the fiscal crisis under President Collor. Second, the economy started opening up to international competition through the enactment of certain trade reforms. However, the economy still displays erratic levels of protectionism. The literature on rent seeking argues that organized interest groups devote resources to capture and try to influence and neutralize the liberalization of the economy, which would endanger the rents they benefit from under existing rules. After decades of state nurturing under the ISI model, the business sector in Brazil was crucial to shaping the path for a new growth model. However, their role in promoting trade openness was far more nuanced. The present work looks at business groups in Brazil since the second half of the twentieth century and the role they played before and during the transition and how their opposition to trade reforms suggests potential rentseeking behaviors. The transition to democracy witnessed the emergence of new business organizations with independent actions that I will account for in this paper. Business organizations were not united at the time of economic reforms and thus reacted differently according to the interests of their members. Institutional factors, amongst which the rise of a new civil society, as well as conjectural factors further constrained the path of economic reforms. / O Brasil sofreu uma parcial mudança, do desenvolvimento estatal à economia de mercado, em seguimento à sua transição à democracia. A economia abriu-se para o comércio internacional, mas ainda hoje apresenta níveis erráticos de protecionismo. O fenômeno da rent-seeking (“busca de renda”) destaca a tentativa de grupos organizados em captar recursos estatais para atividades improdutivas. Como consequência direta, este fenômeno dificulta a realização de reformas comerciais, como grupos de pressão organizados (lobbies), com o fim de proteger os seus próprios interesses. Depois de décadas de modelo de industrialização via substituição de importações (ISI model) incentivado pelo Estado, o setor de negócios no Brasil demonstrou-se crucial para moldar o caminho em direção a reformas econômicas. O presente trabalho analisa o papel desenvolvido pelos grupos empresariais, antes e durante esta transição, e examina como a sua oposição a abertura econômica sugere provável busca de renda. Este trabalho argumenta que as limitações da estrutura corporativa combinadas com o surgimento de novos grupos de pressão, concorrentes entre si, fragmentou a intermediação de interesses. Paradoxalmente, essa fragmentação de interesses e fraqueza coletiva de grupos de pressões limitou os obstáculos as reformas econômicas. O surgimento de uma nova sociedade civil e os fatores institucionais do regime democrático são outros fatores quem dificultaram a criação de reformas econômicas.

Text in Afrikaans / Summary in English / Until recently damages were only awarded in South African law for the loss of an object which was utilised for the generation of income. In Kellerman v South African Transport Services' damages were awarded for the first time for the loss of use of an object, which was used for non-business purposes. In this dissertation the writer aims to indicate that the personal loss that a plaintiff suffers by the loss of the object is so closely related to the physical possession through which it is served, that the Jaw should protect such personal interest. In such circumstances damages should be awarded in principle, irrespective of whether the plaintiff used the object for business purposes or whether he indeed hired a substitute or not. There is room in the South African law for development in the area of delictual damages for the Joss of the possibility to use a material object. / Private Law / LL.M.

L'agglomération de Tripoli Al-Fayhā’a (Liban) est riche d'une histoire complexe et mouvementée. Depuis un siècle, sa société doit faire face à de profondes mutations aux causes et conséquences multiples, mais essentiellement liées à la reconfiguration de ses structures économiques engendrée par son incorporation dans le Liban moderne. Ancienne cité commerciale rayonnante à vocation régionale et internationale, Tripoli a perdu de son dynamisme économique. Elle ne produit plus suffisamment de richesses pour assurer à sa population une continuité de sa prospérité passée. Elle est devenue le lieu de combats physiques, économiques et symboliques dans lequel ses habitants luttent quotidiennement pour assurer leur subsistance. Postulant l'établissement d'une économie désormais principalement fondée sur des logiques de rente foncière et immobilière et de spéculation, notre thèse se propose d'analyser les raisons et la véritable teneur de ce mode de production urbaine particulier, ainsi que ses mécanismes et effets, sous l'angle de l'étude, dans la durée, des spatialités relatives à trois projets urbains : l'aménagement du littoral, la réalisation d'une opération de remembrement à finalité immobilière de jardins périurbains et le réaménagement et la mise en valeur de la médina. L'analyse des systèmes d'actions caractérisant ces trois situations ‒ appréhendées dans leurs dynamiques spatiales, historiques et sociopolitiques ainsi qu’aux échelles locale, régionale, nationale et internationale ‒, invite à questionner le sens des urbanités et de l'éventuelle citadinité en jeu à Tripoli et, au-delà, la nature fondamentale du pouvoir qui s'y exerce. Elle nous conduit alors à nous interroger sur la formation et l'existence, ainsi que P. Bourdieu la désignerait, d'une illusio immobilière, produit et productrice d'un puissant « affect commun » joyeux, laquelle serait parvenue ‒ en suivant la proposition de B. Spinoza ‒ à un état d'imperium aux conséquences humaines et gouvernementales insoutenables. / The Tripoli Al-Fayha’ a (Lebanon) urban area has a complex and eventful history. For a century its society has been facing transformative changes with a multitude of sources and consequences essentially linked to the reconfiguration of its economic structures born of its incorporation into modern Lebanon. Once an ancient and influential commercial city with regional and international reach, Tripoli has lost much of its economic vitality. It no longer creates sufficient wealth to provide its population with the continuation of past prosperity. It has become a place of physical, economic and symbolic battles in which its inhabitants struggle daily to ensure their livelihood. Postulating the establishment of an economy now principally based on a system of land and real-estate rent and of speculation, our thesis is proposing to analyse the reasons and true tenor of this particular process of production of urban space, as well as its mechanisms and effects, as a study, over time, of the spatialities linked to three urban projects: coastal planning, the realization of a real-estate driven land reparcelling of suburban orchards, and the redevelopment and enhancement of the Medina. The analysis of the sets of actions specific to these three situations – taken in their spatial, historical, and sociopolitical dynamics as well as on a local, regional, national, and international scale – invites one to question the meaning of urbanities and of a possible citadinity at play in Tripoli and, beyond this, to question the fundamental nature of the power exercised there. This analysis leads us then to ponder on the formation and existence of, as P. Bourdieu would designate it, a real-estate illusio, produced from and producing a powerful pleasurable “common affect”, which has reached – following B. Spinoza’s proposition – a state of imperium with unsustainable human and governmental consequences.

Para a construção da análise foram estudados e descritos os processos recentes de expansão dos perímetros urbanos de ambas as cidades de maneira a evidenciar o processo de crescente diferenciação espacial ao longo dos anos recentes. A partir do trabalho realizado com os dados de anúncios imobiliários do período de 1995 a 2015, foi possível a realização de uma análise que deu destaque ao movimento dos preços da terra urbana nessa série histórica, o que colaborou para análise e identificação do aumento espacialmente desigual dos preços fundiários, entendidos na dissertação como resultado de estratégias de determinados agentes imobiliários que encontram na produção do espaço urbano o seu “lócus” de reprodução. A partir da identificação e análise de importantes agentes imobiliários que possuem um papel estruturante em ambas as cidades e a análise de entrevistas com representantes de tais agentes e de setores públicos foi realizado um debate acerca da lógica de atuação destes agentes e o papel que a terra urbana assume em suas estratégias de reprodução que interferem diretamente nos processos de estruturação e reestruturação das cidades, e no consequente aumento das desigualdades socioespaciais. Por fim, é realizado um debate acerca da teoria da renda da terra, neste debate argumenta-se sobre à necessidade de retomada de tal teoria, para que possamos qualificar as análises sobre o funcionamento dos mercados fundiários e os atuais processos de “valorização” que estão ancorados na propriedade fundiária. / This dissertation seeks to analyze the urban space process of production by the performance dynamics of certain real estate agents in two medium sized Brazilian cities, Ribeirão Preto and São Carlos, located in the State of São Paulo. For the analysis construction , the recent processes of urban perimeters expansion of both cities were studied and described in order to show the process of increasing spatial differentiation in recent years. Based on the work carried out with real estate adds from 1995 to 2015, it was possible to carry out an analysis that highlighted the urban land prices movement in this historical series, which contributed to the debate on the spatially unequal increase of land prices, understood in the dissertation as a result of land strategies of certain real estate agents, who find in the urban space production their place of reproduction. Based on the identification and analysis of important real estate agents who have a structuring role in both cities and the analysis of interviews with representatives of such agents and public sectors, a debate was held about the these agents acting logic and the role that the urban land plays in its reproductive strategies that directly interfere in the cities (re) structuring processes of, and in the consequent increase in socio-spatial inequalities. Finally, a debate is held about the theory of land rent, in this debate it is argued about the need to retake such theory, so that we can qualify the analyzes on the functioning of the land markets and the current processes of "valorization" that are anchored in land ownership.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This master‟s degree research has the objective of analyzing the reoccupation of the agricultural space of Iturama with the sugar cane plantations, thinking about the tensions between cattle raising and the sugar cane. In cane‟s agribusiness dynamics it is also possible to notice the contradictions in the relations of leasing. The leasing process of lands is realized between the leasing cane mill and the renting soil proprietaries, contract which can have a duration of around ten years. It is necessary to think in how these growers represent themselves in the space of production by their territorialities and land use. We analyze the reality of those who are afflicted in a direct or indirect way by this dynamic of expansion that is occurring in an ever accelerating pace in Triangulo Mineiro‟s/Alto Paranaíba‟s Cerrado since the beginning of the XXI century. The fieldwork allowed us to observe a landscape that looked as something homogeneous at first, but, as we traced and came about long trails inside the cane sea, we found the existence of subjects who have relations of belonging with the place. We analyze the social conditions and territorialities of the reminiscent, those who are still in the countryside, and create territorial bonds which allow them to reinvent themselves by the means of milk production. These bonds are established in the social and work relations manifested in the meadow. / Esta pesquisa de mestrado tem por objetivo analisar a reocupação do espaço agrícola de Iturama-MG com as lavouras de cana-de-açúcar, pensando nas tensões entre a pecuária e a cana-de-açúcar. Nessa dinâmica do agronegócio canavieiro, também é possível perceber as contradições nas relações de arrendamento de terras. O processo de arrendamento de terras é realizado entre a usina arrendatário e proprietários de terras rentistas , contrato que pode durar aproximadamente dez anos. É preciso pensar como os produtores rurais se representam no espaço de produção, através das territorialidades e do uso da terra. Analisamos a realidade daqueles que são atingidos de forma direta e indireta por essa dinâmica de expansão que ocorre de forma acelerada no Cerrado do Triângulo Mineiro/Alto Paranaíba desde o início dos anos 2000. As incursões em campo nos permitiram observar a paisagem que num primeiro momento se mostra de forma homogênea, mas quando traçamos e percorremos longos trajetos em meio aos canaviais descobrimos a existência de sujeitos que possuem relações de pertencimento com o lugar. Analisamos as condições sociais e as territorialidades dos remanescentes, ou seja, os que permanecem no campo, e criam vínculos territoriais que os permitem se reinventar por meio da produção leiteira. Esses vínculos são estabelecidos nas relações sociais e de trabalho estabelecidas no campo. / Mestre em Geografia

Este estudo tem como objetivo explorar e testar se os preços das moradias nas cidades de Rio de Janeiro e São Paulo podem ser explicados por um conjunto de indicadores econômicos selecionados, que inclui variáveis sociais e de custos de construção. Modelos de previsão de preços das residências foram construídos por meio da aplicação de análise fatorial seguida de regressão linear por mínimos quadrados ordinários. Estes modelos não cumpriram com todos os pressupostos estatísticos necessários. Alternativamente, para cada uma das cidades, foi obtido um modelo ajustado a partir da regressão das séries em estado estacionário, seguida da aplicação da técnica de omissão de variáveis a partir do modelo completo. Finalmente, por meio da cointegração de Johansen, foi elaborado um modelo que evidencia o comportamento de longo prazo dos índices de preços. Este modelo foi utilizado para analisar o risco de existência de bolhas imobiliárias nas cidades estudadas, que se mostrou menor em São Paulo que no Rio de Janeiro onde, no entanto, pode-se observar um movimento de convergência dos preços reais para a curva de preços de longo prazo, indicando redução gradual no sobrepreço dos imóveis, se mantida a tendência. / This study aimed at exploring and testing whether house prices in Rio de Janeiro and Sao Paulo could be explained by a set of selected economic indexes, which includes social variables and construction costs. Some prediction models were constructed by applying a factor analysis followed by an ordinary least-squares linear regression. However, these models have failed to comply with all the necessary statistical assumptions. Alternatively, for each of the cities, an accurate model was obtained by applying a stepwise regression technique to a set of steady state variables (first, second and third difference). Finally, it was used the Johansen cointegration to develop a model for the long-term behavior of house prices. The model was used to analyze the risk of real estate bubbles in the studied cities, which was shown to be lower in Sao Paulo than in Rio de Janeiro. However, Rio exhibits a convergence trend in real prices to the long-term price curve, indicating gradual reduction in overpricing, if the trend continues.
