The Phillips Curve forces immediate trade-offs: reduce unemployment and inflation rises, control inflation and unemployment climbs. Fiscal policy targets specific sectors like infrastructure or education but crowds out private investment through higher interest rates. Monetary policy affects the entire economy uniformly—every business faces the same rate change—but loses power at zero rates when liquidity traps emerge. Mixing opposite stances (loose fiscal, tight monetary) funds projects while preventing overheating, though capital inflows from high rates appreciate currency and hurt exports.

Supply-side policies solve trade-offs permanently by shifting LRAS right rather than managing demand—time inconsistency problems arise when political pressures override stability.
