We derive a definition of linear cointegration for nonlinear stochastic processes using a martingale representation theorem. The result shows that stationary linear cointegrations can exhibit nonlinear dynamics, in contrast with the normal assumption of linearity. We propose a sequential...

This paper studies the finite sample properties of the kernel regression method of Boudoukh et al. (1998) for estimating multifactor continuous-time term structure models. Monte Carlo simulations are employed, with a grid-search technique to find the optimal kernel bandwidth. The estimator...
