This article examines persistence and nonlinearity in the US unemployment rate in the post-war period by using a regime-switching unit root test. The empirical results indicate that a regime-switching unit root test outperforms conventional unit root tests and describes unemployment behavior...

A coincidence in time between the volatility break associated with the "Great Moderation" and large changes in the pattern of conditional and unconditional correlations between output, hours and labor productivity was detected by Galí and Gambetti (2009). We provide a novel explanation for...

The time-series approach used in the minimum wage literature essentially aims to estimate a treatment effect of increasing the minimum wage. In this paper, we employ a novel approach based on aggregate time-series data that allows us to determine if minimum wage changes have significant effects...

The paper consists of two parts devoted to the cause-effect dynamic models. In each part of the deterministic properties of the dynamic version of the model are presented. Thus, each of the considered dynamic models can be presented in the form of an equivalent for it the switching trend....

Using time series techniques, we contrast the impact of deregulation in trucking and rail labor markets. During regulation both labor markets were characterized by wages considerably higher than manufacturing wages. In fact, trucking and rail wages had a stable, deterministic relationship prior...

Nonlinear economic variables have been tested for many years with linear models, thus making them insufficient in providing an explanation for real life. As a result of the recently conducted studies, nonlinear time series analyses are observed to be more successful in forming especially the...
