Money is the fundamental mean of exchange in the modern economy, there for it is often an object of counterfeiting and falsification. Wherefore it is not unusual or abnormal that money is under permanent surveillance by the monetary organisations of each country. We understand under adulteration the fabrication of counterfeit coin and paper money. On the other hand falsification represents remaking of original paper money, so that they get a higher value compared to the previous original. The subject of this degree dissertation is the comparative analysis of money counterfeiting and falsification on the territory of Republic Croatia, Federal Republic of Germany and Confederation of Switzerland between 2011 and 2017. The ambition of this degree dissertation is to explain counterfeiting and falsification as a phenomenon of the modern monetary economy, the parameters which influence the adulteration, as well as the suppression of the same. With the comperative analysis of the previously mentioned countries in a particular time span, we achieve a comparison of counterfeiting as an phenomenon inside the European Union and outside of it. We are comparing Germany, which is a member of the EU and the eurozone, and Croatia, which is a member oft he EU but isn`t within the eurozone, directly to Switzerland, which is neither a member oft he EU nor the eurozone. For the comparative analysis oft he above mentioned countries we are going to use fundamental macroeconomic indicators, such as surface and resident numbers, unemployment rate and last but not least, the gross domestic product. With the above-mentioned fundamental macroeconomic indicators we are going to observe the entire revealed counterfeit, as well as its value and the monetary structure.
