dc.description.abstractThe aim of the article is to clarify the controversies surrounding the relationship between inflation and unemployment in the three most economically significant countries in the world (apart from China), namely the United States, Japan, and Germany, during the coronavirus pandemic (from January 2020 to February 2022). The pandemic has had various adverse effects worldwide, including a severe economic crisis lasting from the first quarter of 2020 to the end of the first quarter of 2021. The primary causes of this crisis include declines in aggregate supply due to lockdowns in many sectors of the economy, particularly the service sector. A decrease in aggregate supply should cause not only an increase in unemployment but also an increase in inflation. The article, therefore, hypothesises that the relationships between unemployment and inflation in the countries studied during the above period were unidirectional. To verify this hypothesis, two basic research methods were used: analysis of correlation coefficients between the variables mentioned above and the shape of Phillips curves. Ultimately, the hypothesis was rejected because inflation during this period showed a decreasing tendency (mainly due to a significant drop in commodity prices). The article extends research presented in the literature before 2020, offering additional value by examining the period of the pandemic which precipitated an economic crisis. Future analysis should be expanded to include more variables (including the output gap) in line with the New Keynesian Phillips Curve.en
dc.description.abstractCelem artykułu jest wyjaśnienie kontrowersji dotyczących zależności między inflacją a bezrobociem w trzech najważniejszych pod względem ekonomicznym (oprócz Chin) państwach świata, tj. Stanach Zjednoczonych, Japonii i Niemczech, w czasie pandemii koronawirusa (od stycznia 2020 do lutego 2022 r.). Pandemia ta wywołała szereg niekorzystnych następstw na świecie, w tym poważny kryzys gospodarczy trwający od I kwartału 2020 do końca I kwartału 2021 r. Do podstawowych jego przyczyn należy zaliczyć spadki agregatowej podaży spowodowane lockdownami w wielu gałęziach gospodarki, związanych przede wszystkim z sektorem usług. Spadek agregatowej podaży powinien powodować nie tylko wzrost bezrobocia, ale także wzrost inflacji. W artykule postawiono w związku z tym hipotezę, że zależności między bezrobociem a inflacją w badanych krajach w ww. okresie były jednokierunkowe. W celu jej weryfikacji zastosowano dwie podstawowe metody badawcze: analizę współczynników korelacji między ww. zmiennymi oraz kształtu tzw. krzywych Phillipsa. Ostatecznie powyższą hipotezę odrzucono z uwagi na to, że inflacja w tym czasie wykazywała tendencję malejącą (przede wszystkim ze względu na znaczący spadek cen surowców). Artykuł jest uzupełnieniem badań prezentowanych w literaturze przedmiotu przed 2020 r., a jego wartością dodaną jest badanie okresu pandemii, która spowodowała kryzys gospodarczy. W przyszłości analizę należałoby poszerzyć o większą liczbę zmiennych (w tym o lukę produkcyjną), zgodnie z New Keynesian Phillips Curve.pl
