Econometric Analysis of Recurrent Events

Don Harding and Adrian Pagan have a fascinating new book (HP) that just arrived in the snail mail.  Partly HP has a retro feel (think: Bry-Boshan (BB)) and partly it has a futurist feel (think: taking BB to wildly new places).  Notwithstanding the assertion in the conclusion of HP's first chapter (here), I remain of the Diebold-Rudebusch view that Hamilton-style Markov switching remains the most compelling way to think about nonlinear business-cycle events like "expansions" and "recessions" and "peaks" and "troughs".  At the very least, however, HP has significantly heightened my awareness and appreciation of alternative approaches.  Definitely worth a very serious read.
