Wpływ procesu starzenia i migracji na polską politykę pieniężną

Polska stoi w obliczu szczególnie ostrych przemian demograficznych. Oczekuje się, że wskaźnik obciążenia demograficznego wzrośnie z nieco powyżej 20% w 2000 r. do ponad 60% w 2050 r. Polska doświadczyła ostatnio także ogromnej fali imigracji, głównie z Ukrainy. W niniejszym artykule zbadano, jak starzenie się i migracje wpłyną na polską gospodarkę i jakie konsekwencje mają te dostosowania dla polityki pieniężnej. Stosując model równowagi ogólnej z uwzględnieniem cyklu życia, pokazano, że spadek naturalnej stopy procentowej (NSP) spowodowany procesami demograficznymi jest znaczny i wynosi ponad 1,5 punktu procentowego, choć rozłożony jest na 40 lat. Wpływ przepływów migracyjnych jest stosunkowo niewielki i nie może znacząco złagodzić presji na spadek wskaźnika NSP wywołany starzeniem się populacji. Jeśli bank centralny dowiaduje się o malejącym wskaźniku NSP z opóźnieniem, prawdopodobny jest dłuższy okres utrzymywania się inflacji poniżej celu. W tym przypadku prawdopodobieństwo osiągnięcia zerowej dolnej granicy dla stóp procentowych staje się głównym ograniczeniem polityki pieniężnej, podczas gdy może pozostać pod kontrolą, jeśli bank centralny wykorzysta trendy demograficzne do aktualizacji bieżących szacunków NSP.

Poland faces a particularly sharp demographic transition. The old-age dependency ratio is expected to increase from just above 20% in 2000 to over 60% in 2050. At the same time, the country has recently witnessed a huge wave of immigration, mostly from Ukraine. In this paper, we investigate how aging and migration will affect the Polish economy and what consequences these adjustments have for monetary policy. Using a general equilibrium model with life-cycle considerations, we show that the decline in the natural rate of interest (NRI) due to demographic processes is substantial, amounting to around 1.5 percentage points, albeit spread over a period of 40 years. The impact of migration flows is relatively small and cannot significantly alleviate the downward pressure on the NRI induced by populating aging. If the central bank is slow in learning about the declining NRI, an extended period of inflation running below the target is likely. In this case, the probability of hitting the zero lower bound (ZLB) becomes a major constraint on monetary policy, while it could remain under control if the central bank uses demographic trends to update the NRI estimates in real time.
