Per Åsberg Sommar: Historical data from the Riksbank is vital for macroeconomic theories, Sweden's shift to a 2% inflation target, and the impact of larger economies on small open economies

Historical data from the Riksbank is crucial for testing macroeconomic theories. The Riksbank formally adopted a 2% inflation target in 1995 after allowing the Swedish krona to float. Flexible inflation targets can accommodate supply shocks while maintaining medium-term goals.
