โฆ Synopsis
This paper proposes a new forecasting method in which the cointegration rank switches at unknown times. In this method, time series observations are divided into several segments, and a cointegrated vector autoregressive model is fi tted to each segment. The goodness of fi t of the global model, consisting of local models with different cointegration ranks, is evaluated using the information criterion (IC). The division that minimizes the IC defi nes the best model. The results of an empirical application to the US term structure of interest rates and a Monte Carlo simulation suggest the effi cacy as well as the limitations of the proposed method.

In this paper we develop a latent structure extension of a commonly used structural time series model and use the model as a basis for forecasting. Each unobserved regime has its own unique slope and variances to describe the process generating the data, and at any given time period the model predic

## ABSTRACT This paper focuses on the contemporaneous aggregation of moving average processes. It is shown that aggregating across second (or first)โorder (integrated) moving average processes leads to a macro process whose parameters are exact functions of the parameters of its generation process.
## Abstract This paper investigates whether the forecasting performance of Bayesian autoregressive and vector autoregressive models can be improved by incorporating prior beliefs on the steady state of the time series in the system. Traditional methodology is compared to the new frameworkโin which
