Since tourism constitutes such an integral part of Croatia's economic growth and development, researchers from the Institute of Economics, Zagreb actively engage in research regarding the economic aspects of tourism. Emphasis is thereby placed on various ways in which tourism affects the overall economic activity, especially the price levels and economic growth in countries where tourism is the dominant business sector.
Additional focus is placed on the assessment of elasticity regarding foreign demand for Croatia as a destination and the assessment of durability of positive and negative shock effects, which affect the tourism industry. In their studies on tourist activity, researchers from the Institute of Economics, Zagreb also focus on tourism demand modeling, whereby tourism income modeling and tourist arrival forecasting is given special attention.
