This study aims at revealing the relationship between unemployment and the phenomenon of financialization which has significantly increased its impact of the 1980s. Within this framework, firstly, the ways which financialization may affect unemployment was discussed and the potential relationship between these two variables was tried to be elicited. In this context, the empirical analysis was conducted by using annual data, obtained confidently, for 1980-2015 period of nine developed OECD countries. Within the scope of the empirical analysis, the homogeneity of slope coefficient of the variables was tested on the basis of delta test, and then cross-sectional dependency test was carried out. After the determination of the order of stationarity of the series by employing unit root-test, the long-term relationship and the causality between the variables was investigated by Westerlund co-integration and Dumitrescu and Hurlin causality analyses. According to the results obtained, there is a long-term co-integration and bi-directional causality between financialization and unemployment. Thus, size of financial activity effects unemployment and changes in unemployment also effects the dependency on financial channels.
