Likviditási csapda és deflációs spirál egy inflációs célt követő modellben - a hitelesség szerepe
[A liquidity trap and deflationary spiral in a model for pursuing an inflation target - the role of credibility]

  • Koppány, Krisztián
Registered author(s):

    A nominális kamatszint alsó határának elérése súlyos következményekkel járhat a makrogazdaság egyensúlya és stabilitása szempontjából. Ilyenkor a recesszióval és az infláció túl alacsony szintre szorításával fenyegető negatív sokkhatások a kamatpolitika hagyományos eszközeivel nem ellensúlyozhatók, s - másfajta keresletösztönző lépések híján - a gazdaság könnyen a minimális értéken állandósuló kamatszint állapotába, valamint az egyre inkább visszaeső kibocsátás és árszínvonal spiráljába kerülhet. Elméleti tanulmányunk ilyen helyzetek kialakulásának lehetőségeit vizsgálja egy egyszerű, stilizált makrogazdasági modellben. A likviditási csapda, illetve a deflációs spirál bekövetkezésének formálisan levezetett feltételei jól mutatják, hogy az inflációs cél kitűzése és a gazdaságra jellemző egyensúlyi reálkamatláb szintje, a sokkhatások jellege és nagysága, a jegybank ezekre adott kamatreakcióinak mértéke, valamint az inflációs cél hitelessége miként befolyásolják a kamatpolitika lehetőségeinek határait. A következetések párhuzamba állíthatók a likviditási csapda valószínűségére vonatkozó modellszámítások eredményeivel, valamint annak elkerülésére és az abból való kilábalásra adott, általánosan elfogadott javaslatokkal. Modellünk alapján kimutatható, hogy bár a zérus kamatszint elérésének valószínűsége nullára elméletileg sosem csökkenthető, a likviditási csapda deflációs spirálba való torkollása ugyanakkor az inflációs cél kellőképpen magas fokú hitelessége esetén elvileg kizárható.
