The aim of this study is to analyse the existence of the Dutch disease in the tourism sector in Croatia. Namely, some authors state that the Dutch disease does not exist in the tourism sector in Croatia, while others state the consequences of the Dutch disease as a result of the sudden growth of the tourism sector. The paper assumes that the Dutch disease exists in the Croatian tourism sector and that the growth in demand and inflow of foreign currency in the tourism sector leads to a real appreciation of the domestic currency. It was also assumed that the growth of the tourism sector causes the migration of labour from other sectors to the tourism sector. In this way, an attempt was made to analyse two effects of the Dutch disease, the consumption effect and the resource displacement effect. The analysis showed that tourism receipts have no effect on changes in the real exchange rate due to the causal relationship between the variables mentioned, so that the consumption effect cannot be determined. The paper analysed data on the share of tourism in GDP and the share of agricultural production in GDP in Croatia using the double logarithmic model and the elasticity coefficient, and it was shown that the increase in the share of tourism in GDP affects the decrease in the share of agricultural production in GDP. - this is also true for the share of manufacturing in GDP, indicating the impact of resource churning as a feature of the Dutch disease. Due to the far-reaching importance of tourism growth for Croatia, the paper emphasises the need to find an effective economic policy framework and instruments to prevent possible negative consequences of the Dutch disease for the Croatian economy.
