Panel Data Unit Root testing: Overview [PDF]
arXivThis review discusses methods of testing for a panel unit root. Modern approaches to testing in cross-sectionally correlated panels are discussed, preceding the analysis with an analysis of independent panels. In addition, methods for testing in the case of non-linearity in the data (for example, in the case of structural breaks) are presented, as well

The efficient market hypothesis re-visited: new evidence from 100 US firms [PDF]
In this paper, we test the efficient market hypothesis for 100 US firms listed on the New York Stock Exchange. To test the unit root null hypothesis, we develop a generalized autoregressive heteroskedasticity (GARCH) model that not only caters for the ...

FEBS Open Bio, Volume 15, Issue 5, Page 714-725, May 2025.The thermophilic acetogenic model organism Moorella thermoacetica can utilize lactate as substrate. The formation of lactate by reduction of pyruvate is energetically favorable, but the reverse reaction, the oxidation of lactate to pyruvate with NAD+ as electron acceptor is challenging.

REVISITING HYSTERESIS IN UNEMPLOYMENT FOR TEN EUROPEAN COUNTRIES: AN EMPIRICAL NOTE ON A MORE POWERFUL NONLINEAR (LOGISTIC) UNIT ROOT [PDF]
In this empirical note we use a more powerful nonlinear (logistic) unit root test advanced by Leybourne et al. (1998) to investigate the hysteresis in unemployment for ten European countries for the period 1961-2003.

Is there a Natural Rate of Crime? [PDF]
Studies in the economics of crime literature have reached mixed conclusions on the deterrence hypothesis. One explanation which has been offered for the failure to find evidence of a deterrent effect in the long run is the natural rate of crime.

Red blood cells could protect miRNAs from degradation or loss thanks to Argonaute 2 binding
FEBS Open Bio, Volume 15, Issue 5, Page 810-821, May 2025.The present work investigates the presence and the stability of miRNAs into RBCs, both native and engineered. The observed stability is due to the Ago2 bound resulting in minimal RISC. Indeed, if the miRNA‐Ago2 complex is present, miRNAs are protected from release or degradation and they are biologically active. Thus, RBCs can act as miRNA carriers for

Robust critical values for unit root tests for series with conditional heteroscedasticity errors: An application of the simple NoVaS transformation [PDF]
In this paper, we introduce a set of critical values for unit root tests that are robust in the presence of conditional heteroscedasticity errors using the normalizing and variance-stabilizing transformation (NoVaS) in Politis (2007) and examine their ...
