Testing stochastic cycles in macroeconomic time series

Gil-Alaña, Luis A. - 2000

A particular version of the tests of Robinson (1994) for testing stochastic cycles in macroeconomic time series is proposed in this article. The tests have a standard limit distribution and are easy to implement in raw time series. A Monte Carlo experiment is conducted, studying the size and the...

A fractionally integrated model with a mean shift for the US and the UK real oil prices

Gil-Alaña, Luis A. - 2000

In this article we model the log of the U.S. and the U.K. real oil prices in terms of fractionally integrated processes with a mean shift. We use different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicate that if we model the...

A fractionally integrated exponential model for UK unemployment

Gil-Alaña, Luis A. - 2000

Fractionally integrated models with the disturbances following a Bloomfield (1973) exponential spectral model are proposed in this article for modelling the U.K. unemployment. This enables us a better understanding of the low-frequency dynamics affecting the series, without relying on any...

Cointegrating smooth transition regressions with applications to the Asian currency crisis

Saikkonen, Pentti; Choi, In - 2000

This paper studies the smooth transition regression model where regressors are I(1) and errors are I(0). The regressors and errors are assumed to be dependent both serially and contemporaneously. Using the triangular array asymptotics, the nonlinear least squares estimator is shown to be...

Unemployment and input prices : a fractional cointegration approach

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration … three variables are I(1). But we only find cointegration in the presence of autocorrelated disturbances, which means that … opposed to classical cointegration, which implies long memory and slow reversion to equilibrium. This suggests that an …

Benkwitz, Alexander; Lütkepohl, Helmut; Neumann, Michael H. - 1997

Bootstrap confidence intervals for impulse responses computed from autoregressive processes are considered. A detailed analysis of the methods in current use shows that they are not very reliable in some cases. In particular, there are theoretical reasons for them to have actual coverage...
