This dissertation consists of three chapters on financial friction, misallocation and development dynamics. The first chapter considers how financial frictions and mobility distortions generate the persistence of post-reform development dynamics. I build a general equilibrium model and calibrate it to China. The mobility distortion is an occupation distortion that restricts a proportion of agents to the low-productive sector. A removal of distortions triggers the transition of the economy. Using a calibrated version of the model, the transition path displays slow convergence and mimics the patterns observed in data. The mobility distortion creates high-ability, but poor, agents before the reform. This provides a channel for financial frictions to have longer effect after the reform. Compared with the literature that uses tax distortions, the economy with mobility distortions generates slower convergence. The second chapter is a welfare analysis of the well-documented depressed migrant wage in China from a dynamic perspective. The depressed migrant wage per se attracts fewer migrant workers and lowers the migrants' consumption and the aggregate output. However, it encourages urban entrepreneurs to substitute capital for labor, relaxing the effect of financial frictions. The net effect on output and consumption depends on the stage of development. Initially, it benefits the economy by speeding up TFP growth and capital accumulation in the urban sector. In the later stage, owing to low consumption of migrants, policy intervention can increase aggregate consumption and output. The third chapter investigates why the intergenerational income mobility decreases and the inequality increase for China over the past 30 years. I propose a theoretical overlapping generation model with missing capital markets, increasing the return to human capital and increasing education cost to explain these facts. After the economic reform happens, all levels of wages go up and all families accumulate and update human capital. However, the increasing education cost and credit constraint prevent the children from rural families from accumulating human capital quickly. The urban families accumulate human capital faster than the rural families. These predictions from the model are verified in the census data. Whether this process continues or not depends on the subsidy of education. Government education policy can improve the allocation of education in the economy.

Cette recherche s’inscrit dans le contexte Cambodgien où les traces de la tragédie du génocide des Khmers Rouges sont restées inscrites ; sous ce régime, les Cambodgiens ont subi massivement la violence, la menace de mort, la séparation parent-enfant, la torture, la malnutrition, la suppression des religions et le fait d'une mortalité énorme et ainsi pendant cette période, la configuration de la famille khmère a été gravement touchée. L’objectif de notre recherche est d’étudier comment les modalités dynamiques d’élaborations psychiques des jeunes Cambodgiens actuels influencent la manière dont ils construisent la représentation et le sens par rapport au récit traumatique porté par leurs parents suite au génocide et comment le sens accordé à ce traumatisme influence la construction de leur projet de vie.Nous avons effectué notre recueil des données auprès de 152 étudiants en première année de l’Université Royale de Phnom Penh : 77 filles et 75 garçons, âgés de 17 à 24 ans, 75 étudiants en formation de sciences sociales et humaines et 77 étudiants en formation de sciences exactes. De plus 16 entretiens cliniques ont été effectués : 9 sujets sont en formation de sciences sociales et humaines et 7 sujets en formation de sciences exactes. La dynamique d’élaboration psychique du sujet a été évaluée à l’aide de l’épreuve projective TAT, la représentation a été évaluée à l’aide d’échelles spécifiques et d’entretiens. Le projet de vie a été évalué à l’aide des échelles construites par Rodriguez-Tomé (1987), et d’une technique construite par Safont, De Léonardis et Oubrayrie (1994). L’étude quantitative montre que les sujets de notre échantillon ayant un éventail défensif « souple et varié » qui trouvent la bonne distance entre fantasme et réalité permettant de construire de manière modérée des représentations des conduites symptomatiques des parents, sont capables de s’engager dans des projets réalistes même si l’anxiété est présente. Concernant les sujets ayant un éventail défensif « univoque » (contrôle ou laisser-aller), ils construisent beaucoup plus fréquemment des représentations des conduites symptomatiques des parents. Ils peuvent tout de même s’engager de façon réaliste dans des projets même si l’anxiété est également présente.Notre analyse qualitative montrent l’existence d’une pluralité des discours représentatifs des traces traumatiques portées par les parents : 1/ la désorganisation dramatique de la maisonnée khmère actuelle ; 2/ le rapport aux conduites symptomatiques des parents et 3/la construction d’une mémoire en tant que fait historique, il existe également deux autres discours construits par le sujet, qui représentent la construction du projet : 4/ la construction des stratégies vers les études pour sortir des obstacles et 5/ des choix de formations vers les métiers, pour se réaliser. / This research study is part of the Cambodian context where traces of the tragedy of the genocide of the Khmer Rouge remain inscribed; under this regime, Cambodian people have been subjected to massive violence, death threatening, parent-child separation, torture, abuse, suppression of religions and the fat of enormous mortality during this period, the pattern of Cambodian family has been seriously affected. The aim of our research is to study how the dynamic modalities of psychic elaboration of young Cambodians today influence the way they construct representation and meaning in relation to the traumatic narrative carried by their parents following the genocide and how the meaning accorded to this trauma influences the construction of their life project.The psychic development dynamic of the subject was assessed using the TAT projective test, and the representation was assessed using specific scales and interviews. The life project was evaluated using the scales constructed by Rodriguez-Tomé (1987), and a technique elaborated by Safont, De Leonardis and Oubrayrie (1994).The quantitative study shows that the subjects in our sample with a "flexible and varied" defensive range that find the right distance between fantasy and reality to construct moderately representations of parental symptomatic behaviors, are able to engage in realistic projects even if anxiety is present. Concerning the subjects with a "unequivocal" defensive range (control or letting go), they construct much more frequently representations of the symptomatic behaviors of the parents. They can anyway realistically engage in projects even if anxiety is also present.Our qualitative analysis shows the existence of a plurality of representational discourses of the traumatic traces carried by the parents: 1/ the dramatic disorganization of the current Khmer household; 2/ the relation to the symptomatic behavior of the parents and 3/ the construction of a memory as a historical fact, there are also two other discourses constructed by the subject, which represent the construction of the project: 4/ the construction of the strategies towards the studies to get out of the obstacles and 5/ choices of training towards the professional skills, to be realized.

The aim of the thesis was to analyse indicators and data sets used in the field of sustainable spatial plannig. On the base of the analyses there were spatial indicators of the sustainable development designed. The basic condition to design new indicators it was the accessibility to the elementary datas. The other condition was to design very simply methodology that could be use also for measuring in very small location. The thesis designed idnicators in three main areas of the spatial planning: • landuse, • accessibility of the services, • inner city/town/village traffic. One of the demands for the new indicators set was it´s efficiency for all kinds of the cities in the Czech Republic. This demand was fullfilled by the 3 level methodolgy – the main indicator was measurable for all kinds of settlemets – small villages, small and middle towns and also for cities. The basic methodology (for small villages) was very simple. Indicators were computed from very easy accesible data sets. And this methodology could also be used for larger settlements without any problems. The second level – for small and middle towns – sometimes needs special surveys or special hardware and software. The top of the pyramid is the methodology for cities. In this level there are used detailed analyses and computing methods. The thesis designes the methodology and also checks the practical application up.
