In this note, we investigate a test for the existence of a middle "band of inaction" in a three-regime threshold vector error correction model (TVECM). For this purpose we propose a supremum Wald statistic, derive its limiting distribution and calculate its critical values through simulations.

In this paper a three-regime multivariate threshold vector error correction model (TVECM) with a "band of inaction" is formulated to examine the expectation hypothesis of the term structure (EHTS) of interest rates and uncovered interest rate parity (UIRP) for U.S. and Swiss rates. Tests for no...
