Risk free rate and the inter temporal rate of substitution

[archived_user]

Hi,
Can someone tell me how is the risk free rate is related to the inter temporal rate of substitution?
I know from the formula they are inversely related, but I dont understand the concept behind it.

I think this thread can help you. In my first post I explain the relationship between ITRS and real risk free rate. If you want, we can elaborate further.
