So let's start off by distinguishing between the nominal wage and the real wage.
00:04
So let's say that the nominal wage is equal to w.
00:10
That means that the real wage is equal to w over p, right? to get from nominal to real, you adjust for prices, right? so for example, if you had originally the nominal wage was, say, $20, and the price level was just say one.
00:32
Now when you have the nominal wage is equal to $20 and the price goes to two, the real wage, small w is equal to 10, right? prices have doubled and that means your real wage does only buys half of what it used to be, right? so inflation changes price levels, right? it affects price levels or affected by inflation.
01:00
So that means that inflation affects real wages as well because these things can be slow to adjust, right? wages are not something that get adjusted every single day.
01:14
So when you have inflation going on and nominal wages only adjust slowly, while that's happening, inflation is a the purchasing power of the nominal wage, which is a decline in the real wage, right? but people, right, and this is a little bit weird, people prefer, prefer the nominal wage to be fixed and the price levels up to the nominal wage falling and the price is fixed, even though same real wage.
01:53
And what economists call this is the concept of money illusion, right? it's the fact, though, that, you know, from psychology that people are just not totally rational.
02:09
That's the only way to explain it...
