    },
    {
      "heading": "Key findings",
      "content": "- Pension generosity materially alters saving behavior:\n  - More generous public pension systems affect both private saving and public saving decisions (described generically in the paper).\n- Global interest rate movements are influenced by pension-system generosity:\n  - The paper finds that pension generosity is an important determinant of global interest rate movements (qualitative finding presented).\n- International capital flow patterns respond to demographic change conditional on pension design:\n  - Simulations in the two-country model illustrate that pension-system generosity shapes the direction and magnitude of international capital flows."
    },
    {
      "heading": "Policy implications and recommendations",
      "content": "- Pension system design matters for macrofinancial outcomes:\n  - Policymakers should account for the broader macroeconomic effects of pension generosity, including implications for national saving rates, global interest rates, and international capital flows.\n- Pension reform choices have cross-border consequences:\n  - Reforms that change public pension generosity can alter international capital allocation and global interest rate dynamics, implying a need for coordination-aware assessment."
