A note on nonlinear dynamics in the Spanish term structure of interest rates

subject

description

Abstract This note applies the methodology to test for threshold cointegration recently proposed by Hansen and Seo (2002) [Hansen, B. E. & Seo, B., (2002). Testing for two-regime threshold cointegration in vector error-correction models. Journal of Econometrics, 110, 293–318] to the Spanish term structure of interest rates during the period 1980:1–2002:12. The evidence suggests that nonlinear cointegration between long and short interest rates is clearly rejected, so that a linear cointegration model would provide an adequate empirical description for the Spanish term structure of interest rate.
