We present empirical evidence regarding unemployment dynamics for women and men in eight OECD countries. Unit-root tests are used to examine the unemployment dynamics of women and men. Failure to reject the unit-root hypothesis is consistent with unemployment hysteresis. Rejection of the...

Minimum t statistics to test for a unit-root are available when the form of break under the alternative evolves according to the crash, changing growth, and mixed models. It is shown that serious power distortions occur if the form of break is misspecified, and thus the practitioner should use...

We examine the level of persistence in the gender unemployment gap in eight OECD countries: Australia, Canada, Finland, France, Germany, Italy, Japan, and the United States. We use a new measure for the gender unemployment gap, namely, the ratio of the female to male unemployment rate. Our...

We examine the time series properties of medical net discount rates based on five different medical consumer price indices, namely, medical care, medical services, medical care commodities, physician's services, and prescription drugs & medical supplies that were first analyzed by Ewing, Piette,...

This article tests for the presence of a unit-root in all time series included in the extended Nelson-Plosser data set using the statistics devised by Zivot and Andrews, Perron and Murray and Zivot. It specifies the mixed model characterization of the trend-break stationary alternative that...

We present empirical evidence regarding the structure of unemployment in the US disaggregated by race, ethnicity, and gender. Popp’s (2008) unit-root test reveals that the dynamics of unemployment for all groups is characterized by the hysteresis hypothesis except for Hispanic Males.

Montañés, Olloqui, and Calvo (2005, Journal of Econometrics) argue that use of the Perron-type minimum t-statistics will lead the practitioner to incorrectly assess the time series properties of the variable under investigation when the form of break is misspecified. However, their simulations...

We show that Dickey and Fuller's [1979. Distribution of the estimator for autoregressive time series with a unit root. J. Amer. Statist. Assoc. 74, 427-431; 1981. Likelihood ratio statistics for autoregressive time series with a unit root. Econometrica 49, 1057-1072.] normalized estimator, and...
