In the last two decades, the Republic of Croatia has experienced exceptional growth in tourism and construction and has become quite dependent on them, which is why there is a suspicion that there are signs of the "Dutch disease" in the Republic of Croatia. The "Dutch disease" as a term and phenomenon was first used in 1977 in The Economist, where it described how the sudden increase in wealth in the Netherlands in the 1960s, caused by the discovery of large gas deposits and their export, as Corden (1984) noted, could lead to a number of negative effects on the economy. Similarly, theorists identify certain policies that can neutralise the negative effects of this disease, such as fiscal policy, consumption policy and monetary policy. The aim of this paper is to empirically determine the existence of the "Dutch disease" in the Republic of Croatia and to investigate the assumed effectiveness of policies to neutralise the "Dutch disease", i.e. to determine which policy offers the best solution. According to our research, we conclude that there are signs of the "Dutch disease" in the tourism sector, while they are not evident in the construction sector. The study of policy measures to overcome the "Dutch disease" leads to the conclusion that with a good fiscal model it is possible to neutralise the diseases and at the same time make the growing sector more stable, which is currently necessary for the Republic of Croatia.
