Do higher corporate taxes reduce wages? : Micro evidence from Germany
Because of endogeneity problems very few studies have been able to identify
the incidence of corporate taxes on wages. We circumvent these problems
by using an 11-year panel of data on 11,441 German municipalities' tax
rates, 8 percent of which change each year, linked to administrative matched
employer-employee data. Consistent with our theoretical model, we find a
negative effect of corporate taxation on wages: a 1 euro increase in tax liabilities
yields a 77 cent decrease in the wage bill. The direct wage effect, arising
in a collective bargaining context, dominates, while the conventional indirect
wage effect through reduced investment is empirically small due to regional labor
mobility. High and medium-skilled workers, who arguably extract higher
rents in collective agreements, bear a larger share of the corporate tax burden

The chromatin remodelling enzymes SNF2H and SNF2L position nucleosomes adjacent to CTCF and other transcription
Within the genomes of metazoans, nucleosomes are highly organised adjacent to the binding sites for a subset of transcription factors. Here we have sought to investigate which chromatin remodelling enzymes are responsible for this. We find that the ATP-dependent chromatin remodelling enzyme SNF2H plays a major role organising arrays of nucleosomes adjacent to the binding sites for the architectural transcription factor CTCF sites and acts to promote CTCF binding. At many other factor binding sites SNF2H and the related enzyme SNF2L contribute to nucleosome organisation. The action of SNF2H at CTCF sites is functionally important as depletion of CTCF or SNF2H affects transcription of a common group of genes. This suggests that chromatin remodelling ATPase's most closely related to the Drosophila ISWI protein contribute to the function of many human gene regulatory elements

Cross-reactive CD4+ T cells enhance SARS-CoV-2 immune responses upon infection and vaccination
The functional relevance of pre-existing cross-immunity to SARS-CoV-2 is a subject of intense debate. Here, we show that human endemic coronavirus (HCoV)-reactive and SARS-CoV-2-cross-reactive CD4+ T cells are ubiquitous but decrease with age. We identified a universal immunodominant coronavirus-specific spike peptide (S816-830) and demonstrate that pre-existing spike- and S816-830-reactive T cells were recruited into immune responses to SARS-CoV-2 infection and their frequency correlated with anti-SARS-CoV-2-S1-IgG antibodies. Spike-cross-reactive T cells were also activated after primary BNT162b2 COVID-19 mRNA vaccination displaying kinetics similar to secondary immune responses. Our results highlight the functional contribution of pre-existing spike-cross-reactive T cells in SARS-CoV-2 infection and vaccination. Cross-reactive immunity may account for the unexpectedly rapid induction of immunity following primary SARS-CoV-2 immunization and the high rate of asymptomatic/mild COVID-19 disease courses
