<p>Pro-urban bias in policy is often seen as a common phenomenon in the developing world. Empirical reality though is much more varied. Many governments actively support agricultural producers and rural citizens, even at early stages of development. In addition, the binary distinction between urban and rural bias in policy aggregates over important sub-national variation in the distributive impact of government policies. This dissertation extends the research frontier by analyzing the political roots underlying spatial bias in policy using new theoretical and empirical approaches. First, this dissertation develops a theory that identifies conditions under which politicians will institute pro-urban or pro-rural policies, by considering the threat of a rural insurgency. Second, I argue that elections in rural majority societies can empower citizens in the rural periphery. Competitive elections and high rural turnout induce governments to supply favorable policies to the rural sector as a whole and salient regions in particular. To test the effect of the threat of rural violence, I use new cross-national data on net taxation in the agricultural sector. Data on fiscal transfers and the sub-national effects of agricultural pricing policies in Indonesian districts provide additional evidence for the first hypothesis. To test the effect of elections on urban bias, I exploit a natural experiment from the Indonesian context. Last, I analyze the proliferation of districts in Indonesia from 2001 to 2009, with important implications for future fiscal transfers, and show the process is largely driven by local elite competition within and between districts.</p> / Dissertation

This thesis studies the impact of labor markets on economic growth in both developed and developing countries and China's urbanization, by formalizing dual labor market characteristics and China's Hukou system in two theoretical models. The first is a unified growth model in an open economy environment that captures dual labor market characteristics. The mechanism involves economic growth driven by capital accumulation in the country with Lewisian labor market leading to increasing labor participation at a near constant wage. The model shows that surplus labor plays a critical role in explaining different economic growth paths and structural changes in developing and developed countries, such as China and the US. The second is a dynamic general equilibrium model with endogenous rural-urban migration to analyze the provision of rural and urban government services in China, with special emphasis on the role of the household registration (Hukou) system in shaping its urbanization process. It argues that China’s urban bias policy, which is enabled by the Hukou system restricting rural-urban migration, did not necessarily reduce economic efficiency, rather it might have only raised urban welfare at the expense of rural residents. As the Hukou system also ties people to particular geographical locations, our model argues that China's continuous bias towards coastal and big cities has started to cause economic inefficiency as well as inequality. It suggests that progressive Hukou reform reducing barriers to cross-region migration would improve economic efficiency and welfare.

This thesis has three self-contained articles. Economic growth and trade in human capital: A salient empirical pattern in the East Asian “miracle” is a large increase in output and factor accumulation despite  only a modest increase in TFP. I develop and calibrate a model of growth and catch-up to provide a possible explanation. A novel element of the model is a globalized education market allowing human capital transfer from frontier to developing economies – an assumption motivated by the experience of countries like Korea and Taiwan where domestic universities employed graduates of Western universities to provide advanced training. The political economy of urban bias in dictatorial regimes. In many developing countries, public resource allocation is often biased against the rural population – a policy that hurts the vast majority of the poor living in rural areas. This paper develops a dynamic political economy model of urban bias in a dictatorial regime. A novel result of the model is that urban bias can emerge in predominantly agrarian economies even if there is no bias  in political power toward urban residents. The empirical evidence from a recently compiled country-level panel dataset on agricultural taxes/subsidies is consistent with the prediction of the model. Does agricultural growth cause manufacturing growth? Empirically assessing the impact of agricultural growth on manufacturing growth is challenging because of endogeneity concerns. This paper attempts to circumvent the identification challenge by using weather variations to instrument for agricultural growth. The IV estimations show that agricultural growth has a significant positive impact on manufacturing growth, and it is larger than the OLS estimates. I discuss the empirical implications for agricultural policies, efficiency of the manufacturing sector, and for the role of agricultural growth in Africa's industrialization.

In economic geography, a main research focus is on the relationship between innovation and space. Based on the observations of spatially clustered innovative activities in urban environments, a central argument is that the exchange of innovation-relevant knowledge across firms and other actors as well as the accompanying learning processes are promoted through geographical proximity. Agglomerations are said to offer multiple advantages, e.g. through frequent face-to-face contacts and opportunities for intense collaboration, a common labour pool and shared institutions. From this perspective, a location in large urban environments is beneficial for innovation, while by contrast, being located outside of agglomerations is not (Fitjar & Rodríguez‐Pose 2019). This dissertation relates to growing debates around the unease with the seemingly accepted truths about the strong connection of agglomerations and firm innovation. The research field has been found to be urban-biased, focussed on cases of successful regions and delivering multiple explanations of their success – while neglecting innovations occurring outside of agglomerations and largely portraying such regions and their actors as disadvantaged (Shearmur 2017). Within the emergent studies of innovation in peripheral contexts, some specifics have been proposed based on empirical studies, but a coherent theoretical framework is missing (e.g. Eder 2019). Against this background, this dissertation aims to contribute to a better understanding of innovation from a peripheral perspective based on comparison of firms by location. It explores knowledge creation processes and innovation activities of Hidden Champions in Germany. These highly innovative and globally active manufacturing firms are quite evenly distributed across Germany. By exploring practices and strategies of these firms towards innovation from a comparative perspective, this study investigates the following overarching research question: • What are the characteristics and main drivers of innovation outside of agglomerations and in how far do these differ from those inside agglomerations? This research builds on relational perspectives on economic action by adopting a geographical lens (Bathelt & Glückler 2003, Yeung 2005). It focusses on actors and how they act and interact in space without privileging any spatial scale or mechanism such as local interaction. Spaces and places are not perceived as territorially bounded units but as contexts in which actors organise their often multi-scalar relations. Following these basic theoretical positions, several concepts and approaches are utilised to develop a detailed understanding of firm innovation in space. While notions of slow innovation and the reliance on firm-internal capabilities point towards reduced interaction requirements especially of firms in peripheral regions to innovate (e.g. Shearmur 2015), the proximity approach (Boschma 2005) and the notion of global pipelines (Bathelt et al. 2004) highlight that geographical proximity is not a necessary precondition for interactive knowledge creation and innovation. Based on these conceptual perspectives and linked to the goal of understanding key mechanisms of innovation from a peripheral perspective, the guiding research question is complemented by the following sub-questions: • How and where do firms gain relevant knowledge for their innovation activities? • Which role do internal capabilities as well as external efforts towards innovation play and how do firms assess both dimensions? • What is the role of the firms’ location, especially regarding local options of knowledge creation? Based on a mixed method research design including a quantitative survey among the Hidden Champions and qualitative interviews with representatives of these firms, three dimensions relevant to the understanding of knowledge creation and innovation are considered for the empirical analyses: practices of knowledge creation at the individual level, strategic approaches towards innovation at the organisational level and the socio-spatial contexts in which knowledge creation processes and innovation are organised. The overarching finding of this dissertation is that firms like Hidden Champions largely follow the same principles to innovate independently from their location. Thereby, the results highlight the commonalities of firm innovation in urban and peripheral contexts instead of pointing towards major limitations or specificities of innovation in more peripheral regions. With taking the firm at the centre of analysis, this research demonstrates that regional economic pre-conditions do not necessarily relate to the capacities of firms to innovate. Neither do investigated firms located inside agglomera-tions largely capitalise on options of local interaction, nor do firms located outside of agglomerations face major disadvantages due to the lack of local options to source knowledge and interact. Instead and irrespectively of their location, firms strategically engage in various firm-internal and -external options to gain knowledge and have the capacities to shape their multi-scalar socio-spatial contexts for knowledge creation according to their needs. The results underline that intense interaction with externals is only one out of many options for firms to gain knowledge. Next to strong internal capabilities, non-interactive modes of knowledge sourcing via desk research, for instance, and more informal modes of knowledge creation via the participation in trade fairs have been identified as integral parts of firms’ innovation activities. This study suggests that such forms of ‘selective openness’ have not been sufficiently addressed in the research field so far. Selective openness not only stresses the strategic approaches of firms towards innovation but also the variety of options for knowledge creation which are usually not reliant on or connected to the regional contexts of firms. Moreover, this study finds that the connection between innovation and agglomeration is not as clear as suggested by urban perspectives, at least for the German context. Rather, much of the urban/rural and core/periphery divide seems to be discursively produced. This dissertation complements existing research on the geographies of innovation by providing insights from a peripheral view on innovation. It contributes to current debates on urban-biased perspectives and the dichotomous representation of firm innovation in urban and peripheral contexts. Based on the empirical results, it proposes a more differentiated view on openness and suggests recommendations for place-based policies towards regional development and innovation.:Summary 9 1.

Over three decades of rapid economic growth in China, beginning in 1978, has been accompanied by ever-enlarging urban-rural inequalities in terms of the various aspects of income, welfare, infrastructure, medical treatment, and education (amongst others). These two parts – the urban and the rural - have long been treated separately, without much consideration being given to their mutual linkages (relations). Urban and rural development can, essentially, be interpreted as the deployment of key factors (terms of trade for agricultural products, land requisition, and labor transfer), and the supply of public goods and services (infrastructure, education, insurance, and medical care). Thus, the urban-rural inequalities experienced by China at present can be understood as the consequence of the factor flows (labor, capital, goods, information, and technology, etc.) and agglomeration between these two parts. This thesis aims to investigate urban-rural relations in China in the post-reform era, and their influences on the economic, social, and environmental development in both the urban and the rural areas. The thesis consists of five papers and the cover essay. The first two papers provide a detailed picture of urban-rural relations in China, while the other papers examine the impact of urban-rural relations in terms of population mobility, arable and built land use change, and regional economic inequality in the study area. The findings of the thesis reveal that urban-rural relations in China became gradually intensified in the post-reform era, especially when the central government initiated a shift from a situation of urban bias to comprehensive support for the rural areas. However, the mutual resource flows in the study area still tend to agglomerate in the urban districts, while only reaching the rural peripheries to a limited extent. This is demonstrated in the way in which the urban districts experienced fast and large scale demographic growth and land use change, while slow and small-scale demographic and land use change took place in the peripheries. The urban-rural interface, which is situated between the urban and rural areas, evidences medium-level resource agglomeration. This thesis, through the discussion which it sets out, emphasizes the necessity of exercising both political and market forces in order to achieve balanced urban-rural resource flows in China. Another implication for policy making is to develop more sub-centers at the peri-urban or periphery, making these areas the interface for urban-rural resource linkages. / QC 20110909

Cette thèse présente un ensemble de travaux de recherche en économie politique qui s’inscrivent dans le champ contemporain de la littérature sur la malédiction des ressources naturelles dans les pays en développement. Elle s’intéresse spécifiquement aux liens entre les rentes des ressources naturelles et les institutions politiques et les conflits, puis entre les rentes et la pauvreté sous ses différentes formes. Son champ géographique se situe à plusieurs niveaux, international pour un groupe de pays en développement, monographique et infranational pour le Tchad et ses régions. La première partie, en s’inspirant des théories des changements institutionnels, teste l’hypothèse que les rentes issues de différentes ressources naturelles ont des effets différenciés sur la qualité des institutions dans les pays en développement. Par la suite, elle teste l’hypothèse d’un « système de conflit régional » dans le Triangle République Centrafricaine, Tchad et Soudan. La deuxième partie évalue le dispositif « original » de gestion des revenus pétroliers sur différentes dimensions de la pauvreté au Tchad sur des données d’enquêtes de terrain. Le premier chapitre de cette partie teste l’hypothèse d’un biais urbain dans l’allocation de temps des enfants dans un contexte pétrolier au Tchad. Alors que le second est dédié à l’évaluation de l’impact de l’exploitation pétrolière sur le profil de la pauvreté dans la région productrice en utilisant les méthodes quasi-expérimentales d’évaluation d’impact. / This thesis is a collection of political economy research topics fitting into the contemporary field of literature on the natural resource curse in developing countries. The thesis focuses primarily on the links between natural resource rents and political institutions, before studying the impact of oil resource rents on poverty under its different forms. The geographical scope of the thesis is both macro for a group of developing countries, and micro in the case of Chad and its regions. The first part, drawing on institutional change theories, tests the hypothesis on whether rents generated by natural resources have a detrimental effect on institutions in developing countries, by considering different types of natural resources characterized by their different degree of appropriability. Besides, we evaluate the hypothesis of a "regional conflict system" in the “tormented Triangle” which includes Central African Republic, Chad and Sudan. The second part assesses the impact of the “unusual” system for allocating and managing the expected oil income from the Doba Oil project on many aspects of poverty in Chad by using field survey data. As such, the first chapter of this part tests the hypothesis of an urban bias in children's time allocation in the oil context in Chad. Regarding the second chapter, it investigates the impact of oil extraction on poverty profile in the oil producing region by using quasi-experimental evaluation methods.

Text in Afrikaans / Summaries in Afrikaans and English / Miljoene mense ervaar voedselonsekerheid en een uit elke 50 hanger mense is woonagtig in Suid­ Afrika. Daar is genoeg voedsel op ons planeet om elke mens van 'n voldoende voorraad voedsel te verseker; dit waarborg egter nie voedselsekuriteit aan almal nie. Dit is die voedselparadoks: ondanks globale surplusproduksie van voedsel, ly miljoene mense wereldwyd aan wanvoeding en honger, maar veral in die ontwikkelende lande. Suid-Afrika is geen uitsondering nie en ten spyte van selfvoorsiening in voedsel, balanseer die voedselgelykstelling nie. Daar bestaan 'n ekstreme gaping tussen die produksie en verbruik van voedsel. Gevolglik is die probleem wat nagevors is in hierdie studie die gebrek aan voedselsekuriteit binne 'n wereldkonteks met voedselsurplusse en hoe dit reflekteer in Suid-Afrika. Teen hierdie agtergrond is daar 'n studie gedoen van die oorsake van voedselonsekerheid en die teoriee en verduidelikings van hongersnood. Die fokus van hierdie navorsingstudie is drieledig van aard. Eerstens fokus dit op 'n konseptuele ondersoek na hanger, armoede, voedselsekuriteit en hongersnood in Afrika. Tweedens is ondersoek ingestel na die oorsake vir die gebrek aan voedselsekuriteit in Afrika. Derdens is daar gefokus op Suid-Afrika en is 'n ondersoek gedoen na die voorkoms van hanger, wanvoeding, armoede en die nasionale konteks van voedselsekuriteit met die doel om vraagstukke daaromheen te identifiseer. Daar is bevind dat voedselsekuriteit bepaal word deur die beskikbaarheid van voedsel (aanbod) en die vermoe van mense om dit te bekom (aanvraag). Dit blyk dat die ontwikkelingsproses, regeringsbeleid, ekologiese omgewing en tegnologie, wetenskap en navorsing 'n direkte invloed het op die voedselsekuriteit van mense, en dat Suid-Afrika nie verskil van ander Afrikalande in hierdie verband nie. Hoewel Suid-Afrika voedselselfvoorsiening bereik het, ly miljoene mense honger weens armoede en die gebrek aan aansprake wat bydra tot 'n gebrek aan voedselsekuriteit. Die studie toon dat die Suid-Afrikaanse regering verskeie beleidsmaatreels in plek het ter bevordering van voedselsekuriteit, maar dat dit nie in die praktyk verwesenlik word nie. / Millions of people in the world experience food insecurity and one out ofevery 50 hungry people lives in South Africa. There is enough food on our planet to assure every person of an adequate supply of food; however, this does not guarantee food security for all.

South Africa is no exception and despite self-sufficiency in food, the food equation is not balanced. An extreme gap exists between the production and consumption of food. Consequently, the problem researched in this study is the lack of food security in a world context with surplus food and how this is reflected in South Africa. Against this background a study was undertaken of the causes of food insecurity and the theories and explanations of famine. The focus of this research study is threefold. Firstly it focuses on a conceptual enquiry intohunger, poverty, food security and famine in Africa. Secondly there is an enquiry into the causes of the lack of food security in Africa. Thirdly it focuses on South Africa and an enquiry is done into the incidence of hunger, malnutrition and poverty, and into the national context of food security with the aim of identifying relevant problems in food security. It was found that food security is determined by the availability of food (supply) and the capability of people to obtain it (demand). It appears that the development process, government policy, ecological environment and technology, science and research directly affect the food security of people, and that South Africa does not differ from other African countries in this regard. Although South Africa has achieved food self-sufficiency, millions of people experience hunger because of poverty and the lack of entitlements. The study shows that the South African government has various policy measures for the promotion of food security in place, but that food security does not materialise in practice. / Development Studies / D.Litt. et Phil.
