In the last decade, two very important issues studied by economists are the phenomena of unemployment and inflation. The consecutive changes in prices on an annual basis but also the continuous developments and changes in the working environment make these 2 variables of major importance for the analysis of the global economy. In this thesis, the theory of the Phillips curve, which presents the relationship between unemployment and inflation, will be evaluated through the process of statistical analysis. The countries of choice for the specific investigation are those that belong to the unofficial G7 group (great 7) and they were chosen because they are engines of strength of the global economy over time. In the first chapter, the phenomenon of unemployment will be presented, its types and some suggested ways of mitigating it. In chapter two, the issue of inflation and its consequences will be analyzed theoretically. In chapter three, the concept of the Phillips curve will theoretically be captured while evidence from past academic researches that were carried out for specific countries will be provided. Finally, in chapter 4, the G7 and the countries that are included in it will be analyzed in more detail, resulting in a statistical analysis through the simple linear regression model of the phenomenon of the Phillips curve for these selected countries and with a time period in retrospect from 1998 to 2022.The findings of the research support that the Phillips theory is verified in specific cases but not in the entirety of the whole sample.
