The article explores how development institutions in the real economy can bridge the gap between economic theory and practice. By studying agreements between actors, the researchers aim to harmonize economic science with real-world economic activities. They use a method that combines philosophical knowledge, comparative analysis, and institutional analysis. The findings suggest that the institutional nature of the modern economy is universal, allowing for common ground between different areas of economic research. This can help identify development institutions in the real sectors of the economy to solve practical problems.
