The public pension funds together manage over SEK 1,000 billion in their buffer funds to ensure the financial stability of the pension system over economic cycles. For both the individual pensioner and the national economy, it is essential that the pension funds succeed in achieving a stable but also a good return over time. This project deals firstly with the question of how reliable predictions of market developments are made by pension fund managers. A second area examined is how pension fund managers make risk assessments. A third area concerns decision-making strategies in economic decision-making. Theoretically, the project is based on how people behave and make decisions in economic situations (behavioral economics, economic psychology). The purpose of the research project is to investigate and gain a better understanding of how well pension managers can predict value development, make risk assessments when investing and what decision-making strategies they use to invest fund assets. The aim also includes the applied task of contributing to stronger predictions, more accurate risk assessments and improved decision-making strategies in public pension funds. The project includes three empirical sub-studies and a final applied synthesis study. The results are disseminated in scientific journals and popular media. The project ends with a workshop for pension funds and researchers.
