This paper revisits the well known Feldstein-Horioka saving-investment correlation puzzle from a time series perspective using a sample of 21 OECD countries. We argue that the strong positive correlation between saving and investment as originally identified by Feldstein and Horioka (1980)...

Saikkonen (1991, <italic>Econometric Theory</italic> 7, 1–21) developed an asymptotic optimality theory for the estimation of cointegrated regressions. He proposed the dynamic ordinary least squares (OLS) estimator obtained by augmenting the static cointegrating regression with leads and lags of the first...

This paper considers issues related to testing for multiple structural changes in cointegrated systems. We derive the limiting distribution of the Sup-Wald test under mild conditions on the errors and regressors for a variety of testing problems. We show that even if the coefficients of the...

Recent empirical studies find little evidence of a change in euro area inflation persistence over the post-1970 period. Their methodology is primarily based on standard unit root and structural break tests on the persistence parameter in an autoregressive specification for the inflation process....

Perron and Yabu (2008) consider the problem of testing for a break occuring at an unknown date in the trend function of a univariate time series when the noise component can be either stationary or integrated. This paper extends their work by proposing a sequential test that allows one to test...

Determining whether per capita output can be characterized by a stochastic trend is complicated by the fact that infrequent breaks in trend can bias standard unit root tests towards non-rejection of the unit root hypothesis. The bulk of the existing literature has focused on the application of...

We study estimation and inference in cointegrated regression models with multiple structural changes allowing both stationary and integrated regressors. Both pure and partial structural change models are analyzed. We derive the consistency, rate of convergence and the limit distribution of the...

This paper proposes tests for a mean shift based on a new hybrid estimator of the long-run variance. It is shown that these tests can bypass the non-monotonic power problem of the LM tests while maintaining adequate size properties.

Saikkonen (1991) developed an asymptotic optimality theory for the estimation of cointegrated regressions. He proposed the dynamic OLS estimator obtained by augmenting the static cointegrating regression with leads and lags of the first differences of the I(1) regressors. However, the...

This paper examines the Prebisch-Singer Hypothesis employing new time se- ries procedures that are robust to the nature of persistence in the commodity price shocks, thereby obviating the need for unit root pretesting. Speci…cally, the proce- dures allow consistent estimation of the number of...
