The probability of stopping time
Webb22 juni 2024 · (1) The manipulation is valid. You can sum (integrate) over the expectation of an indicator function that has a default stopping time as its argument, because you are just integrating in time over a probability of default. (2) When is it useful? For CVA calculations for example.
