In [[macroeconomics]], the '''triangle model''' employed by [[new Keynesian economics]] is a model of inflation derived from the [[Phillips Curve]] and given its name by [[Robert J. Gordon]]. The model views inflation as having three root causes: [[built-in inflation]], [[demand-pull inflation]], and [[cost-push inflation]].<ref>Robert J. Gordon (1988), ''Macroeconomics: Theory and Policy'', 2nd ed., Chap. 22.4, 'Modern theories of inflation'. McGraw-Hill.</ref> Unlike the earliest theories of the Phillips Curve, the triangle model attempts to account for the phenomenon of [[stagflation]].
