Typically speaking is a population fall for a country or a certain area that uses the same currency a problem as the cost of standard items will increase and the value of the currency will fall because everyone might have more of it (other than a few that may still have nothing) potentially due to inheritance and a few other things.
Has something like this ever happened on a long term or do a government normally incentivise reproduction/immigration if something like this were to happen (causes of this could be anywhere from a nuclear explosion to chemical tests/contamination to a change in socioeconomic attitudes). I'm just wondering if this is a massive problem if this isn't corrected by a government.
If the population of a certain country or region decreases,the economy of that region will sooner or later start to stagnate,due to the lack of work force and consumers.The inflation that might be created in that region might help for keeping the economic activity,but the long term decrease of the population will lead to recession and prices going down(deflation).I live in a country,where the population is decreasing and the economy will face huge difficulties by 2050.
