Mzdové rozdíly dle vzdělání a velikosti měst na příkladu Číny / Wage Differentials by Education and City Size: Evidence from Chinese Cities

Guo, Se January 2022 (has links)
This thesis uses CFPS's 2014 and 2016 data, from the perspective of differences in education levels and city size, using the two-way fixed-effect model and quantile regression to explore how the different educational workers' nominal monthly income gap changes with the expansion of the urban population. As for city size, on average, for every 1% increase in city size, the nominal monthly income of workers will increase by 0.4%. For every 1% increase in the size of the city, the nominal monthly wage of the college education group will increase by 0.9%, and the wage of the postgraduate workers will increase almost by 1.2%. The results show that only workers with a college and postgraduate education level can expand the monthly income gap with the lowest educational level group as the urban population grows. However, the nominal monthly income gap between the high-school educated group and junior high school and below educated workers is insignificantly affected by the city's expansion.

Estimates of Transportation Energy Savings with Transportation Management Measures for Varying City Size

Edaayf, Ramadan 05 1900 (has links)
Since the early 1970's, fuel consumption in the transportation sector has been one of the major issues facing planners trying to conserve energy. Generally, fuel consumption is influenced directly by the number of vehicles, the distance travelled, the operating speed and the overall population of city. Traffic engineers spent a great deal of time solving such a problem sometimes by introducing the concept of traffic management, the different actions and strategies that reduce the fuel consumption and some other times by estimating the energy saving to evaluate the effectiveness of these actions. Despite best efforts, energy savings estimation have shown wide fluctuations. This study provides a preliminary Investigation of the impact of city size, in the medium range, on potential energy savings accrued due to implementation of Transportation Energy Management Measures (TEMM's). The data sources used includes the energy savings for each of five city size groups, subjected to 23 TEMM's. These data were rearranged and regressed over city size by using the CURFIT technique. Formulae were derived for each of the TEMM's. For the purpose of verification, the Community Benefits Analysis program (CBA) was applied to test some of the obtained results. It is thus concluded that the resulting energy savings, using the regressed equations provide a reasonable way to predict potential benefits across the medium range of city sizes. / Thesis / Master of Engineering (ME)

Essays on City Size Distribution and Real Estate Bubbles

Lucas, John Paul 09 February 2012 (has links)
This is a dissertation about urban systems; within this broad subject I tackle three issues, one that focuses on an observed inter-city relationship and two that focus on an intra-city phenomenon. In Chapter II I adapt a model of random emergence of economic opportunities from the firm growth literature to the urban dynamics situation and present several predictions for urban system dynamics. One of these predictions is that the older the city the larger and more diversified it is going to be on average, which I proceed to verify empirically using two distinct datasets. In Chapter III I analyze the Residential Real Estate Bubble that took place in Miami-Dade County from 1999 to 2006. I adopt a Spatial-Economic model developed for the Paris Bubble episode of 1984-1993 and formulate an innovative test of the results in terms of speculative intensity on the basis of proxies of investor activity available in my dataset. My results support the idea that the best or more expensive areas are also where the greatest speculative activity takes place and where the rapid increase in prices begins. The most significant departure from previous studies that emerges in my results is the absence of a wider gap between high priced areas and low priced areas in the peak year. I develop a measure of dispersion in value among areas and contrast the Miami-Dade and Paris episodes. In Chapter IV I analyze the impact on tax equity of a Florida tax-limiting legislation known as Save Our Homes. I first compare homesteaded and non-homesteaded properties, and second, look within the subset of homesteaded properties. I find that non- homesteaded properties increase their share of taxes paid relative to homesteaded properties during an up market, but that this is reversed during a down market. For the subset of homesteaded properties I find that the impact on tax equity of SOH will depend on differential growth rates among higher and lower valued homes, but during times of rapid home price appreciation, in a scenario of no differential growth rates in property values, SOH increases progressivity relative to the prior system.

Urban crime in Ecuador : three essays on the role of economic inequalities, population density and emotions / Criminalité urbaine en Equateur : trois essais sur les rôles des inégalités économiques, la taille des villes et les émotions

Aguirre sanchez, Andrea carolina 15 November 2018 (has links)
L’Amérique Latine et les Caraïbes sont l’une des régions plus violentes du monde. Le niveau de violence est particulièrement élevé dans les plus grandes villes de cette région (UNODC, 2013). La compréhension des déterminants de la criminalité urbaine est donc un défi majeur pour ces pays. Cette thèse a pour but d’explorer le rôle de trois déterminants de la criminalité en Équateur: les inégalités économiques, la taille des villes et le role des émotions liés aux évènements sportifs tels que les matchs de football.Avant d’entreprendre cette analyse empirique, nous proposons une revue des littératures théorique et empirique sur les déterminants de la criminalité urbaine. Une conclusion importante est que les incitations économiques conduisant à des activités criminelles sont influencées par les schémas de localisation des criminels et des victimes. Partant de ce constat, la thèse propose d’entreprendre trois analyses empiriques à différentes échelles géographiques. Tout d’abord, nous explorons l'effet des inégalités de revenus sur le risque de victimisation en Équateur, en utilisant des données individuelles issues de l’enquête nationale de victimisation. Le principal résultat est que, contrairement aux prédictions, le coefficient de Gini a un effet négatif sur la probabilité d’être victime de vols. Ce résultat pourrait être lié à une ségrégation résidentielle élevée ou à un contrôle social élevé contre la criminalité. De plus, les estimations révèlent une relation croissante et concave entre le niveau de revenu des victimes et la probabilité de victimisation concernant les vols de véhicule, qui augmente avec un revenu mensuel jusqu’à 5,100 dollars, et puis diminue.Ensuite, nous testons l'existence d'une prime de criminalité urbaine (criminalité plus élevée dans les zones urbaines) en Équateur, à l’échelle des paroisses. Le principal résultat indique que la taille des villes a une influence non-monotone sur le taux d’homicide. La probabilité de constater un ou plusieurs homicides est plus élevée dans les paroisses les plus peuplées. Toutefois, le taux d’homicide diminue avec le niveau de population dans les paroisses où se produisent des homicides. Concernant les crimes contre la propriété, les résultats confirment l’influence positive de la population sur le nombre de crime par habitant. Enfin, nous estimons l’impact des matchs de football sur le nombre d'homicides et de crimes contre la propriété dans 16 cantons d’Équateur, à l’échelle intra-urbaine. L’objectif est d’étudier l’influence des matchs de football sur les profils temporels et géographiques des crimes, ainsi que l’impact des émotions (frustration et euphorie) liées aux résultats des matchs sur la criminalité. Les résultats indiquent que le nombre d'homicides augmente 0.18% avant le match, tandis que le nombre de crimes contre la propriété augmente 12% après le match, à proximité du stade. Les matchs de football entraînent également une diffusion spatiale de la criminalité dans des quartiers éloignés des stades. Les jours de matchs, les crimes contre la propriété diminuent 0.88% avant le match et les homicides diminuent 0.05% pendant le match, dans les quartiers éloignés des stades. Après le match, les homicides et les crimes contre la propriété augmentent de manière significative dans les quartiers éloignés des stades. Enfin, l'effet des émotions sur les homicides et les crimes contre la propriété n'est pas significatif au niveau agrégé, alors qu’il est significatif en ce qui concerne les homicides commis dans la capitale de l'Équateur, Quito. / Latin America and the Caribbean (LAC) is one of the most violent regions in the world. Importantly, higher levels of violence prevail in most urbanized LAC cities (UNODC, 2013). Understanding the determinants of urban crime is therefore a major challenge for those countries. The purpose of this dissertation is to explore the role of three crime determinants in Ecuador: economic inequalities, city size, and the emotions caused by soccer events.Before conducting this empirical analysis, we first review the theoretical and empirical literature on urban crime determinants. An important conclusion is that economic incentives that lead individuals to commit crime are influenced by the location pattern of criminals and victims. Building on these considerations, we perform three empirical analyses at different geographic levels.First, we explore the effect of income inequality on victimization in Ecuador, using data at the individual level thanks to the Ecuadorian Victimization survey. The main result is that, contrary to the predictions, the Gini coefficient has a negative effect on victimization by robbery. This result could be related to a high residential segregation or a high social control against crime. In addition, we provide evidence for an increasing and concave relationship between the income level of victims and the probability of victimization by vehicle theft, which first increases with a monthly household income up to $5,100, and then falls.Second, we test the existence of an urban crime premium (higher crime in urban areas) in Ecuador, at the parish level. Our main result is that population exerts a non-linear influence on the homicide rate. The probability that a homicide happens is higher in larger parishes. However, the homicide rate decreases with population in parishes with positive homicides. By contrast, the results regarding property crimes confirm that the level of population increases the number of pecuniary crimes per inhabitant.Third, we explore the effect of soccer matches on the number of homicides and property crimes in 16 cantons of Ecuador, at the intra-city level. The aim is to test whether soccer matches alter the temporal and spatial patterns of crime, and the role of emotions (frustration and euphoria) resulting from soccer matches on crime. Results reveal that the number of homicides increases by 0.18% before the match whereas the number of property crimes increases by 12% after the match, near the stadium. Soccer matches also cause spatial spillovers of crime in locations distant from stadiums. On game days, the number of property crimes falls by 0.88% before the match and the number of homicides falls by 0.05% during the match, in these distant locations. After the game, the homicides and property crimes significantly increase in locations distant from stadiums. Finally, the effect of emotions on homicides or property crimes is not significant at the aggregate level but it is significant regarding homicides that occur in the capital of Ecuador, Quito.

Ensaios em economia regional e urbana

Amarante, Adriano de January 2011 (has links)
Nesta tese propõe-se responder a três principais questões: No primeiro ensaio estuda-se o impacto dos investimentos privados de multinacionais do setor automobilístico no Brasil sobre o crescimento da atividade econômica dos municípios. Os resultados obtidos sugerem que as cidades onde se instalam este tipo de investimentos alcançam um desempenho superior aos outros grupos de municípios sem este recurso. Estes resultados apontam para uma subprovisão de bens públicos esperada em todo agrupamento de cidades, e um crescimento da atividade industrial no grupo de municípios de domicílio dos investimentos em detrimento a um crescimento abaixo da média do grupo de controle dos municípios adjacentes. No segundo ensaio proposto nesta tese, levanta-se a questão sobre qual o impacto do investimento em infraestrutura viária sobre a economia dos municípios do estado de Santa Catarina. Para responder esta questão, o método de regressão de dados em painel foi utilizado para identificar e mensurar o efeito do investimento público em rodovias interestaduais sobre o crescimento econômico municipal. Os resultados apontam para um efeito positivo sobre os municípios adjacentes e aqueles cortados pela rodovia federal. O setor agropecuário tende a perder valor agregado dado uma possível realocação de recursos para o setor de serviços e indústria de transformação. No terceiro e último ensaio, sobre a dinâmica da distribuição espacial da população no Brasil, tem-se como ideia central testar a Lei de Zipf tendo por base as estimativas da dinâmica populacional dos municípios brasileiros e seus limites populacionais (K). Recentes trabalhos na área de economia regional e urbana, e da nova geografia econômica (NGE), retomam o tema sobre a distribuição espacial da população entre as cidades. A principal questão neste ensaio é descobrir sobre a existência de uma tendência na distribuição do tamanho dos municípios brasileiros a atender a Lei de Zipf. Após as estimativas para um estado estacionário na dinâmica populacional dos municípios brasileiros e as estimativas por regressão quantílica da lei de potência, rejeitou-se em quase a totalidade das amostras a existência de um expoente igual a -1. / In this thesis propose to reply three principals’ questions. In the first essay examines the impact of private investment of multinational automobile industry in Brazil about the growth of economic activity of municipalities. The results obtained suggest that the municipalities that settle the investments reach a performance superior to other groups of municipalities. These results point to a underprovision expected of public goods in all groups of municipalities and increasing industrial activity in the municipalities of domicile of the investment over a growth below the average of the control group of adjacent municipalities. In the second essay proposed in this thesis, the question is about what the impact of highway infrastructure investment on the economy of the municipalities in the State of Santa Catarina. To answer this question makes use of panel date regression method to identify and measure the effect of public investment on the municipal economic growth. The results does are positive on the neighbouring and crossways interstate highway, the agriculture sector loses added value due a possible relocation of resources to service and manufacture sector. In the third essay, on the dynamics of spatial distribution of population in the Brazil, the core insight this is to test the Zipf’s Law from estimates of population dynamics of Brazilian municipalities and their population limits (K). Lately, studies on the approach of urban and regional economy and of new economic geography (NEG) recovers’ theme on the spatial distribution of population among cities. The central question in this essay, is whether there is a trend in the distribution of sizes of municipalities meet Zipf's law? After estimates for a steady state in the population dynamics of Brazilian municipalities and estimates for regression quantiles power law rejected in almost all of the samples the presence of an exponent equal to-1.
