Hello! I was just curious if you could explain in depth the inter-temporal budget constraint in an infinite horizon. What are the important factors to focus on when working on a problem dealing with an infinite inter-temporal budget constraint. What are the steps to finding consumption/savings within each period, as well as interest rate, when the consumer wants to maximize the discounted flow of utility?
