Hi Piotr, this is not an easy question and there is no general solution. There are some major differences between countries. Let's take a look at USA first. US dollar is an export asset for USA. Selling printed US dollars is a big business for USA. As the main reserve currency USA have this luxury to print these fancy green bills and sell them as money. Inflation is then shared with emerging counties (especially oil exporters) and US doesn't suffer from it.

Other countries have to consider consequences for money printing. Weakening your local currency may seem good for exporters yet it hurts the poorest part of population. As at least half of goods is produced somewhere abroad, things like phones, TVs, clothes, foreign food become more and more expensive. People don't like it and they don't feel they need to vote for politicians playing with money printing. So the government will think twice before starting printing money.

So going back to your original question - what should countries do? The answer is - it depends on particular country. If it is a rich country with a strong economy, then they can afford printing some more money. If not, then they should consider this really carefully.
