What is the relationship between interest rates and currency prices?

If a country raises its interest rates, its currency prices will strengthen because the higher interest rates attract more foreign investors This answer sounds exactly logical as I think about it, yet, in economics books, under the uncovered interest rate parity model, a country with a higher interest rate should expect its currency to depreciate. I would agree with this proposition in the long run an expensive currency will hurt exports... but in the very short run... let's say once the CB declaires a rise in interest rate, by how much should one expect the currency to appreciate? Is there any formula for this?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
