      "heading": "Interpretations and implications",
      "content": "- Mechanisms identified:\n  - Digitalization → increased price flexibility (firms adjust prices more frequently or responsively).\n  - De-globalization → greater sensitivity of domestic inflation to domestic economic slack (stronger domestic link between output gap and inflation).\n- Policy-relevant implication:\n  - While modest steepening of Phillips curves may reduce the sacrifice ratio for disinflation somewhat, it does not fully account for the 2021–22 inflation surge; policy responses should consider both slope changes and possible outward shifts in the Phillips curve.\n\n---\n\n Content in this bundle\n\n- Working Paper\n  - Working Paper (Markdown version){rel=\"alternate\" type=\"text/markdown\"}\n  - Working Paper (PDF){rel=\"external\" type=\"application/pdf\"}\n\n---\n\nSource: https://www.imf.org/en/publications/wp/issues/2023/05/12/has-the-phillips-curve-become-steeper-533315"
