In Austria, the law is forcing employers to pay 14 wages instead of the usual 12 (one per month) per year for almost every employee. More specifically, employees get a 13th payment around July called "Urlaubsgeld" or Vacation money and a 14th payment around December called "Weihnachtsgeld" or Christmas money. Thus, if you compare monthly payments with its neighbour germany, where you can but usually do not get 13th and 14th payment, it seems like austrians are getting less money paid than germans, but the difference is that Austrians get theirs 14x and Germans 12x. Also, in Austria, the 13th and 14th payment are significantly less taxed than the usual twelve.
Now I have no idea what are the reasons for that, but what I was thinking about was the following. It is a fact that most Austrians are going on Vacation in December/January and July/August and use their 13th and 14th salary for doing so. And as we all know, when money from economy x get spent abroad (which is what happens when people go to vacation), economy x is becoming weaker. Isn't it then the case, that Austrian economy is weakening itself by organizing two big payments during vacation times by encouraging Austrians to spend money abroad?
