We consider a number of unit root tests for micro panels where the number of individuals is typically large, but the number of time periods is often very small. As we discuss, the presence of a unit root is closely related to the identification of parameters of interest in this context. Calculations of asymptotic local power and Monte Carlo evidence indicate that two simple t-tests based on ord...

Self-Employment Dynamics, State Dependence and Cross-Mobility Patterns This paper analyzes the mobility between self-employment, wage employment and nonemployment. Using data for men in West Germany, we find strong true state dependence in all three states. Moreover, compared to wage employment, non-employment increases the probability of self-employment significantly, and self-employment goes ...

We study the effect of political ideology on sustainable development, measured as investment in genuine wealth, in a dynamic panel of 79 countries between 1981 and 2013. We find that a switch from a left-wing or centrist government to a right-wing government has a robust positive and statistically significant effect on investment in genuine wealth. We find no evidence of opportunistic cycles in...

This paper empirically investigates the impact of macroeconomic uncertainty on the spreads of credit default swaps (CDS). While existing literature acknowledges the importance of the levels of macroeconomic factors in determining CDS spreads, we show that the second moments of these factors—macroeconomic uncertainty—predict CDS spreads even in the presence of traditional macroeconomic factors s...

By a combination of protein chemistry and recombinant DNA methods a glycine-rich region was found to be located near the carboxyl terminus of the nucleolar specific phosphoprotein, nucleolin, from Novikoff hepatoma (protein C23) and Chinese hamster ovary cells (100-kDa nucleolar protein). A sequence of 192 amino acid residues was derived from partial sequences of cyanogen bromide and N-bromosuc...

We have developed a new approach to quantitatively reconstruct past changes in evaporation based on compound-specific hydrogen isotope ratios of vascular plant and Sphagnum biomarkers in ombrotrophic peatland sediments. We show that the contrast in H isotopic ratios of water available to living Sphagnum (top 20 cm) and in the rooting zone of peatland vascular plants can be used to estimate “f ”...

We obtained evidence that increased stability of nucleophosmin/B23 is involved in antiapoptotic effect of ras during serum deprivation. Nucleophosmin/B23 in serum-deprived (0% serum) NIH-3T3 cells was found to be highly unstable with a half-life less than 4 h. In contrast, nucleophosmin/B23 in serum-deprived ras-transformed (RAS-3T3) cells was as stable as that in serum-supplemented NIH-3T3 or ...

Human rhinovirus-C (HRV-C) has been implicated in more severe illnesses than HRV-A and HRV-B, however, the limited number of HRV-C complete genomes (complete 5' and 3' non-coding region and open reading frame sequences) has hindered the in-depth genetic study of this virus. This study aimed to sequence seven complete HRV-C genomes from Malaysia and compare their genetic characteristics with the...

The hepatic metabolism and the choleretic effect of homochenodeoxycholic acid, the C25 homologue of chenodeoxycholic acid, were investigated in the hamster. After intravenous administration of 3H-labeled homochenodeoxycholic acid into biliary fistula hamsters, more than 80% of the radioactivity was recovered in bile in 4 h. A relatively small proportion of homochenodeoxycholic acid was present ...
