By: Rickard Sandqvist, Supervisor: Ulf Jansson, Urban and regional planning, advanced level, Master thesis for master exam in Urban and regional planning, 30 ECTS credits, Language: English, Key words: recent income inequality trends, the creative class, kuznets hypothesis and theories of income inequality, income inequality with the IT revolution in post-industrialized countries, SURE estimation, OLS estimation, income inequality measures.  The aim of the thesis is to analyze the development of income inequality for countries that have longer time series available. I use theories and hypothesises of income inequality and do some development of Kuznets hypothesis. My research question is: does post-industrialized countries face a second Kuznets curve with the IT revolution? I use OLS (ordinary least square) and SURE (seemingly unrelated regression equation) estimations to answer my research question. I use data from the world bank and I analyze data from mainly countries in europe and north and south america. My results is that there is evidence that post industrialised countries face a second Kuznets curve and I do the conclusion that this is depending on the IT revolution.
