Point processes with alternating arrival rates arise in various applications, including financial modelling. We obtain explicit expressions for the distributions of these processes, i.e. for the sums ∑m=1nX(m) and ∑m=1n(-1)mX(m), where X(m) are independent exponentially distributed random variables with alternating parameters. The distribution of the compound Poisson process with Markov modulation and with exponentially distributed jumps is also studied.
