Previous issue date: 2015-03-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The purpose of this dissertation consists of two articles, it is to analyze the influence of agglomeration economies and the Problem of Modifiable Area Unit (MAUP) have on the salary level. For this, two articles are needed to better explanation of these data. The first is dedicated to exploit economies of agglomeration from the earnings equations. Through the Exploratory Spatial Data Analysis (ESDA) and the 2010 Census data, there is the existence of spatial associations in the regional aggregates analyzed, such as spatial agglomerations or homogeneous regions (clusters), and atypical observations (outliers). In the second part of the article dedicated to the estimation of the econometric model, use up wage equations with formulation based on the model developed by Fingleton (2003), whose main hypothesis points to a positive relationship between wage differentials and job density. In the second article, we present a case of MAUP with the IBGE Census 2010 data on the average salary of Brazilian workers. It is discussed and demonstrated the need to consider the differences in results arising from the regionalization chosen by the researcher. The analysis focuses on five levels: micro, municipalities, micro, meso and Brazilian states, using for this purpose, earnings equations (Mincer), proposed by Mincer (1974). When analyzing Mincer equations, from the perspective of different regional scales, a first point to Brazil, the role of its variables becomes very important, especially for education. The results show that the conclusions drawn and the policies adopted, from income regressions, are dependent on the choice of geographically analyzed. / O objetivo dessa disserta??o, composta por dois artigos, ? analisar a influ?ncia que as economias de aglomera??o e o Problema da Unidade de ?rea Modific?vel (MAUP) t?m sobre o n?vel salarial. Para tanto, dois artigos s?o necess?rios para melhor explana??o destes dados. O primeiro ? dedicado a explorar as economias de aglomera??es a partir das equa??es de rendimentos. Por meio da An?lise Explorat?ria de Dados Espaciais (AEDE) e dos dados do Censo 2010, verifica-se a exist?ncia de associa??es espaciais, nas agrega??es regionais analisadas, tais como aglomera??es espaciais ou regi?es homog?neas (clusters), e observa??es at?picas (outliers). Na segunda parte do artigo, dedicada ? estima??o do modelo econom?trico, utilizam-se equa??es salariais, com formula??o baseada no modelo desenvolvido por Fingleton (2003), cuja principal hip?tese aponta para uma rela??o positiva entre os diferenciais de sal?rios e a densidade de trabalho. No segundo artigo, apresenta-se um caso de MAUP, com dados do Censo 2010 do IBGE, sobre o sal?rio m?dio dos trabalhadores brasileiros. ? discutida e demonstrada a necessidade de se considerarem as diferen?as nos resultados obtidos, oriundas da regionaliza??o escolhida pelo pesquisador. A an?lise se centra em cinco n?veis: microdados, munic?pios, microrregi?es, mesorregi?es e estados brasileiros, utilizando, para tanto, equa??es de rendimentos (mincerianas), propostas por Mincer (1974). Ao se analisar equa??es mincerianas, sob a perspectiva de diferentes escalas regionais, ponto in?dito para o Brasil, o papel de suas vari?veis torna-se de suma import?ncia, com destaque para a educa??o. Os resultados mostram, que as conclus?es obtidas e as pol?ticas adotadas, a partir de regress?es de rendimento, s?o dependentes da escolha do n?vel geogr?fico analisado.
