From the 1980s onwards, in developed countries (and not only) we observe an upward trend in the ratio of public debt to GDP. In many countries public debt has exceeded GDP, and in the world's most indebted country – Japan – has exceeded 250% of GDP and continues to grow rapidly. These figures raise concerns among economists and emerge questions about whether public finances in these countries are on a sustainable path.
