Neighborhood and Economic spillovers: four essays on the role of culture, institutions and geography / Voisinage et débordements économiques: quatre essais sur le rôle de la culture, des institutions et de la géographiePlaigin, Charles 31 May 2012 (has links)
The dissertation suggests that geographical, institutional, religious and cultural links may be determinants of growth. We address a number of issues in this thesis. The starting point is naturally a study on growth, while the main focus is on the analysis of inequalities between countries with respect to their environment, and also on inequalities within countries.<p>The very first step of the study, presented in Chapter one, is to build such non-physical relations between countries. In this chapter, we present both the choices and methods used to model the institutional and cultural weights matrices. Chapter 1 also presents a comparative study between the different matrices built. The final aim of this chapter is to identify the differences between the geographical, institutional and cultural environment.<p>The following chapter incorporates these innovative new types of matrices in a study on growth. An externality growth model is therefore developed that takes proximities between entities into account, whether geographical, institutional or cultural. The purpose of the chapter is threefold. First, it compares the results obtained from spatial econometrics methods with classical regression, where observations of growth are considered as independent. Second, it examines whether the development of an externality model improves the quality of the estimation. Third, it investigates whether the institutional and cultural types of proximity make sense compared to the geographical one.<p>Chapter 3 narrows the analysis of countries’ dependency with regard to their neighborhood, whether geographical, institutional or religious, and a quintile regression approach allows us to check whether the countries' wealth level matters. Do the poorest countries react in the same way as richer ones regarding the wealth of their geographical, institutional and religious neighbors? The gross impact of neighboring wealth on a country’s wealth is then estimated, and some relative effects of the three matrices combined are also shown, as well as the robustness of the estimates.<p><p>Finally, Chapter 4 analyzes the dependence of poverty regarding neighborhood. The relative wealth and poverty of the neighborhood are examined as factors that can influence a country’s poverty level. The poverty index used is the proportion of people living on less than one or two dollars a day. The study only considers the developing countries as data for the developed countries on the proportion of this variable is near zero. Once again, the final aim is to check whether a country’s poverty is exacerbated by its geographical, institutional and religious neighborhood poverty or if it takes advantage of neighborhood wealth to manage its own poverty issues.<p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Vliv strukturálních fondů a fondu soudržnosti na konvergenci: Analýza okresů Slovenska / The Impact of Structural Funds and Cohesion Fund on Convergence: The Case of Slovak DistrictsKotrč, Michal January 2020 (has links)
Do Structural Funds and Cohesion Fund contribute to the improvement of economic performance across Slovak districts? In order to answer the question this thesis explores the impact of EU funds invested within specific operational programmes over the programming periods 2007-2013 and 2014-2020 on the decrease in unemployment rate and on the increase in real wage and employment rate. Besides the standard panel data regression technique we also apply a spatial autoregressive model due to the presence of spillover effects between regions. This thesis thus goes beyond the existing literature on the evaluation of the impact of EU funds in Slovakia as it incorporates spatial effects in the analysis. In comparison with the results of the baseline fixed effects model, the estimated impact of EU funds in the spatial autoregressive model is smaller and in certain cases even negative. Hence the results raise doubts about the efficiency of EU funds. Furthermore, after including the spatial effects we find that the existence and significance of the economic convergence across Slovakia depends not only on the chosen economic indicator but also on the specification of regional units.

Unternehmensgründungen: Motivation und direkte BeschäftigungswirkungenWeyh, Antje 03 February 2010 (has links)
Der Gründung von neuen Unternehmen wird seit einigen Jahren sowohl von Wissenschaftlern als auch von Politikern eine wachsende Aufmerksamkeit zuteil. So sind diese überzeugt, dass die Gründungsaktivität einen positiven Beitrag für die wirtschaftliche Entwicklung eines Landes leistet. Schon aus dieser Überzeugung heraus werden in Deutschland Gründungen mit unterschiedlichsten Unterstützungsleistungen gefördert. Einerseits werden z. B. mittels Gründungszuschuss und Einstiegsgeld Gründungen aus Arbeitslosigkeit unterstützt mit dem hauptsächlichen Ziel, die Arbeitslosigkeit der betreffenden Person zu beenden oder zu vermeiden (vgl. Sozialgesetzbuch Drittes Buch - Arbeitsförderung - § 57 und Sozialgesetzbuch Zweites Buch - Grundsicherung für Arbeitsuchende - § 29). Andererseits fördert der Staat beispielsweise mittels der EXIST-Programme innovative Gründungen bzw. Gründungen aus Hochschulen und Forschungseinrichtungen, von denen auch erwartet wird, dass sie in größerem Umfang Arbeitsplätze schaffen, Effizienz sicherstellen, den Strukturwandel beschleunigen, für mehr Vielfalt am Markt sorgen und nicht zuletzt den Wettbewerb steigern und damit das Wachstum einer Volkswirtschaft vorantreiben. Sicherlich sind aber von den meisten Gründungen keine „Wachstumswunder“ zu erwarten, vor allem nicht von Gründungen aus Arbeitslosigkeit. Ein Großteil der Gründer sichert mit der Selbstständigkeit nur das jeweils eigene Einkommen. Viele Gründungen bleiben klein, schaffen keine oder kaum Arbeitsplätze und tragen nur in äußerst geringem Maße zum Wachstum einer Volkswirtschaft bei.
Ein erstes Ziel dieser Arbeit ist es, Gründungen aus Beschäftigung und Gründungen aus Arbeitslosigkeit miteinander zu vergleichen, denn beide Gründungsalternativen müssten sich im Hinblick auf ihre Motivation und ihren Erfolg deutlich voneinander unterscheiden. Nur sehr wenige Studien zum Gründungsgeschehen differenzieren nach dem der Selbstständigkeit vorangegangenen Erwerbs- bzw. Nichterwerbsstatus, obwohl bereits zu diesem Zeitpunkt Unterschiede im Entscheidungsverhalten zwischen arbeitslosen und beschäftigten Personen vorliegen. Während, rein monetär betrachtet, Beschäftigte nur zwischen ihrem jetzigen Einkommen und dem zukünftig erwarteten Einkommen aus der Selbstständigkeit entscheiden müssen, besteht für Arbeitslose die Wahl zwischen Einkommen aus einer möglichen abhängigen Beschäftigung, Einkommen aus einer eventuellen Selbstständigkeit oder weiterer Arbeitslosigkeit. Bezüglich des Erfolges sind Gründungen aus Beschäftigung vermutlich stärker darauf ausgelegt, zu wachsen und Arbeitsmöglichkeiten für andere Personen zu schaffen als Gründungen aus Arbeitslosigkeit, bei denen die Existenzsicherung des Gründers vorrangig sein dürfte. Ein weiteres, zweites Ziel der Arbeit besteht darin die bisherige empirische Evidenz zum Gründungsgeschehen zu erweitern, zu validieren bzw. zu verifizieren, indem Modelle der räumlichen Ökonometrie zur Analyse des regionalen Gründungsgeschehens genutzt werden. Ein solcher Schritt fehlt in bereits vorhandenen Studien ganz oder die Einbeziehung räumlicher Effekte erfolgt nur indirekt und unvollständig, was die erzielten Ergebnisse verzerren kann. Allein durch die Beobachtung und Kommunikation mit anderen Gründern im näheren Umfeld oder durch Netzwerke und Cluster dürften regionale Effekte entstehen, die das eigene Gründungsvorhaben beeinflussen.
Um diese beiden Ziele zu verfolgen, gliedert sich die Arbeit in vier einzeln für sich lesbare Kapitel, für die in den nachfolgenden Abschnitten die jeweils detaillierten Forschungsschwerpunkte beschrieben sind. Die Analysen zur Gründungsaktivität aus Beschäftigung und aus Arbeitslosigkeit umfassen dabei vor allem die regionale Ebene (Kapitel 2 und Kapitel 3) berücksichtigen aber auch die individuelle Dimension (Kapitel 5). Während in den ersten beiden Kapiteln der Gründungszeitpunkt interessiert, widmen sich die beiden anschließenden Kapitel den direkten Beschäftigungswirkungen, d. h. der Entwicklung der Beschäftigung in der Gründung selbst bzw. dem Erfolg, der von Gründungen allgemein (Kapitel 4) und speziell von Gründungen aus Arbeitslosigkeit zu erwarten ist (Kapitel 5).

Socioeconomic Development In The Southeast Region Of The United States From 1995 - 2000: A Structural Equation Modeling And A Gis Modeling ApproachEldev-Ochir, Erdenechimeg 15 December 2007 (has links)
This research presented in this study demonstrates that county level population growth, economic growth, and localized social structure are interrelated. An analysis of the spatial distribution of these factors in the Southeast Region of the United States during the period of 1995-2000 also indicates the importance of differences in rural versus urban and coastal versus non-coastal areas as well as the importance of such factors as highways, large cities, and universities in economic, population, and social structure interrelationships. An extensive dataset is used in the analysis as a number of analysis tools including statistical analysis, econometric models, spatial econometric models, structural equation models, and GIS mapping.

不動產評價之空間計量與地理統計 / Spatial Econometrics and Geostatistics for Real Estate Valuation陳靜宜, Chen, Jing Yi Unknown Date (has links)
近年來由於地理資訊系統(GIS)的快速發展發,空間資料分析開始受到重視並在社會科學領域中逐漸扮演重要的角色。雖然一般的統計方法已在傳統資料分析上發展已久,然而它們卻不能有效地說明空間性資料,並且無法充分處理空間相依或空間異質性問題。一般而言,空間資料分析主要有兩個分派:模型導向學派與資料導向學派。本文研究目的在於應用空間統計方法合理且充分地評估房地產價值,研究方法包含地理統計(克利金和共克利金)、地理加權迴歸與空間特徵價格模型等,並且以台中市不動產資料進行實證探究。這項新的研究技術在不動產評價領域中將可提供更好的解析能力,使其在評價過程中或是不動產投資決策時,成為一個更強而有力的分析工具。 / In recent years, spatial data analysis has received significant awareness and played an important role in social science because of the rapid development of Geographic Information System (GIS). Although classic statistical methods are attractive in traditional data analysis, they cannot be executed seriously for spatial data. Standard statistical techniques didn’t sufficiently deal with spatial dependence or spatial heterogeneity issues. Generally, the model-driven method and the data-driven method are mainly the two branches of the spatial data analysis. The purpose of this paper is to apply spatial statistics methods including geostatistical methods (kriging and cokiging), geographically weighted regression, and spatial hedonic price models to real estate analysis. It seems to be completely reasonable and sufficient. The real estate data in Taichung city (Taiwan) is used to carry out our exploration. These techniques give better insight in the field of real estate assessment. They can apply a good instrument in mass appraisal and decision concerning real estate investment.

A new estimation approach for modeling activity-travel behavior : applications of the composite marginal likelihood approach in modeling multidimensional choicesFerdous, Nazneen 04 November 2011 (has links)
The research in the field of travel demand modeling is driven by the need to understand individuals’ behavior in the context of travel-related decisions as accurately as possible. In this regard, the activity-based approach to modeling travel demand has received substantial attention in the past decade, both in the research arena as well as in practice. At the same time, recent efforts have been focused on more fully realizing the potential of activity-based models by explicitly recognizing the multi-dimensional nature of activity-travel decisions. However, as more behavioral elements/dimensions are added, the dimensionality of the model systems tends to explode, making the estimation of such models all but infeasible using traditional inference methods. As a result, analysts and practitioners often trade-off between recognizing attributes that will make a model behaviorally more representative (from a theoretical viewpoint) and being able to estimate/implement a model (from a practical viewpoint).
An alternative approach to deal with the estimation complications arising from multi-dimensional choice situations is the technique of composite marginal likelihood (CML). This is an estimation technique that is gaining substantial attention in the statistics field, though there has been relatively little coverage of this method in transportation and other fields. The CML approach is a conceptually and pedagogically simpler simulation-free procedure (relative to traditional approaches that employ simulation techniques), and has the advantage of reproducibility of the results. Under the usual regularity assumptions, the CML estimator is consistent, unbiased, and asymptotically normally distributed.
The discussion above indicates that the CML approach has the potential to contribute in the area of travel demand modeling in a significant way. For example, the approach can be used to develop conceptually and behaviorally more appealing models to examine individuals’ travel decisions in a joint framework. The overarching goal of the current research work is to demonstrate the applicability of the CML approach in the area of activity-travel demand modeling and to highlight the enhanced features of the choice models estimated using the CML approach. The goal of the dissertation is achieved in three steps as follows: (1) by evaluating the performance of the CML approach in multivariate situations, (2) by developing multidimensional choice models using the CML approach, and (3) by demonstrating applications of the multidimensional choice models developed in the current dissertation. / text

[fr] IMPACT DE L INTENSIFICATION DES BOVINS DANS LES MUNICIPALITÉS AYANT DES BIOMES DU CERRADO ET DE L AMAZONIE / [en] IMPACT OF BEEF CATTLE INTENSIFICATION IN MUNICIPALITIES WITH CERRADO AND AMAZON BIOMES / [pt] IMPACTO DA INTENSIFICAÇÃO DA PECUÁRIA DE CORTE NOS MUNICÍPIOS COM BIOMAS CERRADO E AMAZÔNIAGUSTAVO ABREU MALAGUTI 05 May 2022 (has links)
[pt] O processo de ocupação humana no território brasileiro tem provocado, há séculos,
profundas alterações no meio ambiente. Desde os primeiros habitantes, a natureza tem
sofrido alguma mudança no seu formato, em algum grau de escala. Se os povos
tradicionais nativos possuem uma preocupação em conciliar a relação homem-meio
ambiente, a invasão europeia inverteu toda essa lógica. Dos processos primitivos até o
uso da mecanização moderna, o Brasil pós-1500 mostrou a força humana sobre a natureza
e seus consequentes impactos. Apesar dos esforços maiores ou menores, das denúncias
propaladas desde do período colonial, avança-se a destruição de ecossistemas de suma
importância local e global. Diante desse cenário, o país possui biomas com enorme perigo
de perdas irreversíveis se nada for feito. Neste contexto, esta tese tem como objetivo
entender essas transformações com olhares histórico, geográfico e econômico,
culminando numa análise quantitativa do uso da terra de 2004 a 2019 focada nos
municípios dos dois principais biomas brasileiros ameaçados, Cerrado e Amazônia. Por
meio de diferentes instrumentos da econometria espacial cujos princípios são as primeiras
leis da Geografia, se pretende identificar os fatores que modificaram o uso da terra no
período citado e propor medidas para atenuar o impacto do principal vetor de
desmatamento direto nos biomas citados: a pecuária. Por meio dessa análise, pretende-se
avaliar como a intensificação da bovinocultura de corte altera as emissões, a configuração
do uso da terra, pode auxiliar no cumprimento da Lei de Proteção da Vegetação Nativa e
gerar ganhos econômicos dentro de uma área com mais de 1.700 municípios. O objetivo
final é determinar qual a melhor política de intensificação da atividade de pecuária de
corte considerando o trade-off meio ambiente e economia. A escolha permitirá que o país
consiga oferecer aos consumidores domésticos e internacionais uma atividade mais
sustentável com minimização do impacto ambiental gerado e receitas majoradas. Com
isso, a tese mostra que as alterações no uso da terra em quatro diferentes classes –
agricultura, pecuária, floresta e outros usos – são fenômenos locais cujo somatório tem
um impacto global relevante. Os resultados reforçam a importância de políticas públicas
ambientais e agrícolas e observarem as diferenças entre os municípios em sua formulação
e implementação. Há, para o Brasil, um imenso potencial tanto de ampliar a área florestal
com a intensificação e de restaurar grandes áreas liberadas com o incremento do sistema
produtivo de carne bovina. Assim, o país tem nas suas mãos uma chance ímpar de ter uma
pecuária sustentável econômica e ambientalmente com uma política governamental que
considere a diversidade local. / [en] The process of human occupation in Brazilian territory has caused profound
changes in the environment for centuries. Since the first inhabitants, nature has undergone
some change in its shape, to some degree of scale. If native traditional peoples have a
concern to reconcile the man-environment relationship, the European invasion has
reversed all this logic. From primitive processes to the use of modern mechanization,
post-1500 Brazil showed human strength under nature and its consequent impacts.
Despite the major or minor efforts, the denunciations proposed since the colonial period,
the destruction of ecosystems of great local and global importance is advanced. Given
this scenario, the country has biomes with enormous danger of irreversible losses if
nothing is done. In this context, this thesis aims to understand these transformations in
historical, geographical, and economic views, culminating in a quantitative analysis of
land use from 2004 to 2019 focused on the municipalities of the two main threatened
Brazilian biomes, Cerrado and Amazon. Through different instruments of spatial
econometrics whose principles are the first laws of geography, it is intended to identify
the factors that modified land use in the period mentioned and propose measures to
mitigate the impact of the main vector of direct deforestation in the biomes mentioned:
livestock. Through this analysis, it is intended to evaluate how the intensification of beef
cattle culture alters emissions, the configuration of land use, can assist in complying with
the Native Vegetation Protection Law and generates economic gains within an area with
more than 1,700 municipalities. The goal is to determine the best policy of intensification
of beef livestock activity considering the trade-off environment and economy. The choice
will allow the country to be able to offer domestic and international consumers a more
sustainable activity with minimization of the environmental impact generated and
increased revenues. Considering all these facts, the thesis shows that changes in land use
in four different classes – agriculture, livestock, forest, and other uses – are local
phenomena whose sum has a relevant global impact. The results reinforce the importance
of environmental and agricultural public policies and the observer in the differences
between the municipalities in their formulation and implementation. For Brazil, there is
an immense potential for both expanding the forest area with intensification and restoring
large areas released with the increase of the beef production system. The country has in
its hands a unique chance to have a sustainable livestock economically and
environmentally with a government policy that considers local diversity. / [fr] Le processus d occupation humaine sur le territoire brésilien a provoqué de profonds
changements dans l environnement pendant des siècles. Depuis les premiers habitants, la
nature a subi quelques changements dans sa forme, à un certain degré d échelle. Si les
peuples autochtones traditionnels ont le souci de concilier la relation hommeenvironnement, l invasion européenne a inversé toute cette logique. Des processus
primitifs à l utilisation de la mécanisation moderne, le Brésil post-1500 a montré la force
humaine sous la nature et ses impacts conséquents. Malgré les efforts majeurs ou mineurs,
les dénonciations proposées depuis la période coloniale, la destruction d écosystèmes
d une grande importance locale et mondiale progresse. Compte tenu de ce scénario, le
pays a des biomes avec un énorme danger de pertes irréversibles si rien n est fait. Dans
ce contexte, cette thèse vise à comprendre ces transformations avec des vues historiques,
géographiques et économiques aboutissant à une analyse quantitative de l utilisation des
terres de 2004 à 2019 des municipalités des deux principaux biomes brésiliens menacés,
le Cerrado et l Amazonie. A travers de différents instruments d économétrie spatiale dont
les principes sont les premières lois de la géographie, il est prévu d identifier les facteurs
qui ont modifié l utilisation des terres dans la période mentionnée et de proposer des
mesures pour atténuer l impact du principal vecteur de déforestation directe dans les
biomes mentionnés : l élevage. Grâce à cette analyse, il est prévu d évaluer comment
l intensification de la culture des bovins modifie les émissions, la configuration de
l utilisation des terres, peut aider à se conformer à la Loi sur la protection de la végétation
native et générer des gains économiques dans une zone comptant plus de 1.700
municipalités. L objectif est de déterminer la meilleure politique d intensification de
l activité du bétail en tenant compte de l environnement et de l économie compromis. Ce
choix permettra au pays d être en mesure d offrir aux consommateurs domestiques et
internationaux une activité plus durable avec une minimisation de l impact
environnemental généré et une augmentation des revenus. Avec cela, la thèse montre que
les changements dans l utilisation des terres dans quatre classes différentes –
l agriculture, l élevage, la forêt et d autres utilisations – sont des phénomènes locaux dont
la somme a un impact mondial pertinent. Les résultats renforcent l importance des
politiques publiques environnementales et agricoles et regardent les différences entre les
municipalités. Pour le Brésil, il existe un immense potentiel à la fois pour l expansion de
la zone forestière avec l intensification et la restauration de grandes zones libérées avec
l augmentation du système de production de bœuf. Le pays a entre ses mains une chance
unique d avoir un élevage durable économique et écologiquement avec une politique
gouvernementale qui prend en compte la diversité locale.
