On initial descent; when the First Officer pulled the thrust levers back; the right engine did not slow normally. All the engine perimeters were normal. We adjusted the thrust lever several times. At first the engine would slow to about 88% N1; but after a few more attempts it became totally unresponsive. The engine was stable at 92% N1. As we descended the engine slowly accelerated to 94%.We reviewed the Jammed Thrust Lever Checklist in the QRH. We decided since the engine was stable and still within parameters; we would wait to shut the engine down until we had everything else done. I decided that we needed to divert to longer runway (our destination runway is just 6;000 FT) due to the increased landing distance and the abnormality of a single engine approach. We decided that ZZZ seemed to be the best option with a 10;000 FT runway; major airport emergency services; controlled airspace and good passenger handling capabilities.I contacted the Dispatcher who concurred that ZZZ appeared to be the best option. We contacted ATC about the diversion; declared an emergency and then began preparing for the approach. Once we were caught up we executed the QRH procedure and shut the engine down. We requested a long final to make sure we did not feel rushed. The First Officer executed a beautiful single engine approach and landing with a normal rate of touchdown. We exited well before the end of the runway. The fire trucks followed us back to the gate.
The Captain then started looking in the QRH for a procedure to try and run. I told the Captain that just two months ago I had my AQP check ride and received the exact same problem with the engine thrust non-responsive. I told him that we ended up running the 'Thrust Lever Jammed' checklist which leads you to shut down an engine.
A CRJ-200 flight crew; faced with an unresponsive right engine thrust lever; shut the engine down; declared an emergency; and diverted to an airport with longer runways and better facilities for CFR; maintenance; and passenger handling.
