In this paper, we extend the impulse saturation algorithm to a class of dynamic models. We show that the procedure is still correctly sized for stationary AR(1) processes, independently of the number of splits used for sample partitions. We derive theoretical power when there is an additive...

We establish that under mild conditions, testing for the individual significance of an impulse indicator in the conditional model, selected on the basis of prior testing of its significance in the impulse saturated marginal model does not require bootstrapping critical values. Extensive Monte...

This paper has three different motivations. Firstly, we wish to contribute to the debate on whether French inflation has been persistent since the mid-eighties. Empirical evidence in this domain has been mixed. We use the standard method of testing for breaks in the mean of the inflation series...

In this paper, the first panel on sources of funding for Portuguese publicly owned museums is explored. There has been little work in this field worldwide, and none for Portugal. Evidence in this paper seems contrary to that relating to the UK and to the US. We find that incremental budgeting...

We develop a new automatically-computable test for super exogeneity, using a variant of general-to-specific modelling. Based on the recent developments in impulse saturation applied to marginal models under the null that no impulses matter, we select the significant impulses for testing in the...

OLS estimation of an impulse-indicator coefficient is inconsistent, but its variance can be consistently estimated. Although the ratio of the inconsistent estimator to its standard error has a t-distribution, that test is inconsistent: one solution is to form an index of indicators. We provide...

A two-stage procedure based on impulse saturation is suggested to distinguish mean and variance shifts. The resulting zero-mean innovation test statistic has a non standard distribution, with a nuisance parameter. Hence, simulation-based critical values are provided for some cases of interest....

In this paper, we build a model for the yield curve in Germany, from 1975 to 2001, and use it to test the Lucas Critique. We provide a first application of the new general-to-specific automatic model selection algorithm embodied in PcGets to term structure odeling, and use new super exogeneity...

Monte Carlo evidence is provided as to the efficiency of the impulse saturation estimator in a location-scale model with heavy-tailed distributions. Comparisons show that the IS estimator is always more efficient than the OLS and can even outperform the Method of Moments estimator in some instances.
