Economic indicators are data used to analyze and monitor economic evolution. Key indicators include GDP for comparing countries, inflation which measures price growth, unemployment rate reflecting labor market utilization, investments aimed at increasing production, and personal consumption for the purchase of goods and services. The objectives of this paper are to analyze the role of institutions in the economic development of the Republic of Croatia and to assess the effectiveness of the economic policies and strategies implemented by these institutions. Institutions play a crucial role in economic growth by implementing strategies and policies. Institutional economics studies these institutions, which are vital for a stable economy. Global competitiveness measures a country’s ability to market its products internationally. In Croatia, economic potentials are based on human and natural resources. Growth and development depend on institutions such as the constitution and the rule of law. Croatia has progressed, particularly through EU membership, and is involved in several key international financial institutions, including the World Bank, the IMF, and the European Investment Bank. This paper is written using economic analysis, statistical analysis, comparison, compilation, and description methods.
