However, this becomes difficult if we do not have enough information, for example because we do not observe the underlying process at a high enough frequency. As a result, if the response of one variable to a shock to another takes place `in the nick of time' this shock remains unidentified. We introduce a structural vector-autoregression model with Markov-switching heteroskedasticity in the data generating process that allows us to study instantaneous impulse-response relationships with the proper selection of a supporting `catalyst', which can be easier to find than an instrumental variable.
