The Randomized Kaczmarz Method with Application on Making Macroeconomic PredictionsWan, Dejun 01 January 2016 (has links)
This paper will demonstrate the principles and important facts of the randomized Kaczmarz algorithm as well as its extended version proposed by Zouzias and Ferris. Through the analysis made by Strohmer and Vershynin as well as Needell, it can be shown that the randomized Kaczmarz method is theoretically applicable in solving over-determined linear systems with or without noise. The extension of the randomized Kaczmarz algorithm further applies to the linear systems with non-unique solutions. In the experiment section of this paper, we compare the accuracies of the algorithms discussed in the paper in terms of making real-world macroeconomic analyses and predictions. The extended randomized Kaczmarz method outperforms both the randomized Kaczmarz method and the randomized Gauss-Seidel method on our data sets.

Marcos evolutivos e conceituais sobre internacionalização de empresas no Brasil: uma análise da década de ouro (1999-2009) / Evolutionary and conceptual frameworks for the internationalization of companies in Brazil: an analysis of the golden decade (1999-2009)Luciana Mara Gonçalves Araújo 25 March 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A internacionalização pode ser definida de forma ampla e abrangente como um processo crescente e contínuo que envolve operações de uma determinada empresa com outros países. Refere-se às trocas econômicas, políticas e culturais entre nações e às relações resultantes dessas trocas, que podem ser pacíficas ou conflituosas, de complementaridade ou concorrência. É determinante a forma como essas empresas traçam suas estratégias e ações para conquistarem novos mercados fora de seus mercados domésticos. A nível mundial, o marco inicial da internacionalização de empresas se deu em virtude das viagens marítimas dos séculos XV e XVI e à formação dos impérios coloniais, como Espanha e França. No Brasil, a experiência com a internacionalização de empresas é recente e se intensificou a partir de 1990, atingindo seu apogeu no decênio 1999 2009. A presente pesquisa tem como objetivo fazer uma macro análise do processo de internacionalização de empresas brasileiras, no sentido de dentro para fora, tomando como referência uma visão teórica, histórica e de análise conjuntural afim de mostrar as diferentes estratégias usando o decênio de 1999 a 2009 como recorte temporal. Para entender a problemática, a pesquisa foi esboçada em cinco objetivos específicos: o primeiro, traçando um panorama geral da internacionalização partindo de uma macro análise para uma micro análise desse fenômeno, o segundo apresentando e discutindo os principais aspectos teóricos que envolvem as estratégias e motivações de internacionalização, o terceiro avaliando de que forma as teorias, econômicas e administrativas, permitem interpretar e explicar o fenômeno da internacionalização, o quarto identificando e descrevendo os ciclos econômicos que impulsionaram a internacionalização de empresas tanto no mundo como no Brasil e, o último dedicando-se a identificar e descrever dentro de um contexto histórico e econômico a periodização e a espacialização do processo de internacionalização de empresas no Brasil e o que representou a década de ouro(1999 a 2009) para a internacionalização de empresas brasileiras. Face aos objetivos da pesquisa, a metodologia utilizada neste estudo é de natureza quali-quantitativa, com caráter explicativo, baseada em uma lógica dedutiva, partindo de premissas abstratas até discussões empíricas. Por fim, a pesquisa evidencia os motivos pelos quais as empresas buscam o mercado externo e por que o decênio 1999 2009 foi tratado como a Década de Ouro da internacionalização.

Makroekonomická analýza s využitím postupů prostorové ekonometrie / Macroeconomic Analysis with Spatial Econometric ApproachesMacková, Simona January 2017 (has links)
Spatial econometrics can bring a useful approach to macroeconomic analysis of regional data. This thesis delineates suitable cross-section data models regarding their geographical location. Neighbourhood relation is used for the analysis. The relation of neighbourhood among the regions is expressed using spatial weight matrix. We focus on spatial autocorrelation tests and introduce processes of finding a suitable spatial model. Further, we describe regression coefficients estimates and estimates of spatial dependence coefficients, especially method of maximum likelihood estimates. Besides illustrative examples we apply chosen basic spatial models on real macroeconomic data. We examine how they describe relation between household incomes, GDP and unemployment rate in western Europe. Results are compared with a linear regression model.
