Real-time rational expectations and indeterminacy

This paper uses the technique of Lubik and Schorfheide [Lubik, T., Schorfheide, F., 2004. Testing for indeterminacy: an application to U.S. monetary policy. The American Economic Review 94 (1), 190-217] to test for indeterminacy in a New Keynesian Model. Using real-time, instead of revised data on the output gap, the results suggest indeterminacy both before 1979 and after 1982.
