Maybe try using a search engine like Google or DuckDuckGo next time before blurting out nonsense at others
only because you didn't like what they said!
There are various studies with various number of participants and data size targeting different groups:
Btw I don't understand what's the catch with making local currency cheap? Yeah, China does that but what's the point, how does it make them competitive? Instead of lowering the purchasing value, lower salaries. I believe it's not as easy as I make it here but I don't understand the logic.
On the global scale where they have to export their goods that are produced domestically (so with workers being paid in Yuan) if their fiat is cheaper for the global customer, their products become cheaper as well.
The way I understand it is the following and I try to simplify it:
Imagine two importers A and B who both have a $100 capital wanting to import pens!
A imports them from China. B imports them from Germany.
Both pens are worth $1 each so each importer imports 100 of them. They each add 20% profit and sell them domestically at $1.2.
Lets say 1 USD == 10 CNY and 1 Chinese pen is worth 10 CNY. Then China lowers the exchange rate to 1 USD == 20 CNY without changing their product prices.
All of a sudden importer A can import 200 pens with the same $100 capital. So A will have more goods to sell therefore more profit to make.
Right now the sale in China has just doubled because of that.
Since A is making more profit in total, he can also lower his own profit % to crush the competition. He can for example sell the Chinese pens for $1.1 each.
Now B sees that he is losing the market to the competition since the market is being flooded with more pens and at cheaper prices. Majority of people are also more willing to buy the $1.1 pen instead of the more expensive ones at $1.2.
All of a sudden B decides to import pens from China as well, only to not be pushed out of the competition.
Now China has quadrupled their sales selling 400 pens instead of 100. That also translated into more inflow of money into China and most importantly more jobs that would greatly counter the inflation caused by dumping the CNY.
Just replace pen with any other goods. Like their cars. Their smart phones and so on.
In fact the Chinese automotive industry has been crushing its competitors over the past year, taking their shares in previous years and some say they are now pushing them completely out.
