Energy use patterns in German manufacturing since 2003

The manufacturing sector accounts for a substantial share of German GDP, employment and carbon emissions. Therefore, the manufacturing sector's energy use and carbon emissions are of crucial importance for reaching Germany's climate goals. In this paper, we analyse energy use patterns in German manufacturing between 2003 and 2014, using rich administrative micro-data. We find that although the manufacturing sector has been faced with rising energy costs as a share of total costs, energy use has not declined except briefly during the economic crisis. We also find that energy intensity in the manufacturing sector has not decreased substantially. In contrast, carbon intensity has fallen slightly between 2003 and 2014. This can be attributed to changes in the fuel mix

Do climate policies lead to outsourcing? Evidence from firm-level imports

Rising energy prices might lead to adjustments along the supply chain and make firms outsource energy-intensive processes. This could lead to carbon leakage. I provide empirical evidence whether energy price-induced offshoring occurs using firm-level data on energy use, imports, and material purchases. I document that import shares in German industry have increased between 2009 and 2013, and that energy prices correlate positively with imports. Despite this positive correlation, I show in a quasi-experimental setup that a sudden drastic drop in electricity prices has not led firms to significantly reduce their imports or their domestic material purchases relative to an unaffected control group. This holds for very electricityintensive firms; for firms using easily tradable goods; and both for regular importers with a trade network and occasional/non-importers

Do manufacturing plants respond to exogenous changes in electricity prices? Evidence from administrative micro-data

Climate policy often implies increasing energy prices. Due to incomplete regulation across the globe, concerns about their competitiveness and employment effects play an important role in the policy debate. Using micro-data on electricity network charges and the official census data for Germany, we study the impact of rising electricity costs on plant performance in German Manufacturing. Electricity network charges are determined through regulation in Germany and therefore exogenous to manufacturing plants, while making up a substantial share of final electricity prices. Our estimates imply a negative own-price elasticity of electricity of -0.4 to -0.6 in the short-run: A one cent increase in average network charges leads to a decrease in electricity procurement of roughly 3 %. There is suggestive evidence that this elasticity of response is decreasing over time, in line with nonlinearly increasing marginal abatement costs. Generally, we do not find significant effects on revenues, investments or capital stocks

Brückenstrompreis : Fehler aus der Vergangenheit fortführen?

Bedingt durch den Angriffskrieg Russlands auf die Ukraine und der damit einhergehenden Verknappung in der Erdgasversorgung sind deutsche Energie- und Strompreise in den vergangenen Monaten stark gestiegen. Zum Schutz des Wirtschaftsstandorts Deutschland hat das Bundeswirtschaftsministerium eine Begrenzung der Strompreise für energieintensive Unternehmen vorgeschlagen. Aus Sicht von Wissenschaftler/innen des ZEW Mannheim und der Universität Mannheim gibt es allerdings keine Hinweise auf einen negativen Einfluss der Strompreise auf die Wettbewerbsfähigkeit deutscher Industrieunternehmen. Empirische Studien zur Befreiung der vollständigen Zahlung der Erneuerbare-Energien-Gesetz(EEG)-Umlage sowie zu steigenden Netzentgelten zeigen, dass Industrieunternehmen mit ihrem Stromverbrauch auf Strompreise reagieren, nicht aber mit ihrer Beschäftigung oder ihrem Umsatz. Dies liegt auch daran, dass für die meisten Industrieunternehmen der Energiekostenanteil am Umsatz deutlich unter 5 Prozent liegt und andere Standortfaktoren für die Wettbewerbsfähigkeit relevanter sind. Eine Begrenzung industrieller Strompreise schwächt Anreize zur Innovation und zum Stromsparen ab. Diese Anreize aber sind dringend notwendig, um die Klimaziele zu erreichen. Während Versorgungssicherheit in der kritischen Infrastruktur sichergestellt werden muss, ist eine breite Subventionierung industrieller Strompreise für die Transformation zu einer klimaneutralen Wirtschaft eher kontraproduktiv

Is Germany becoming the European pollution haven?

Relative prices determine competitiveness of different locations. In this paper, we focus on the role of regulatory differences between Germany and other EU countries which affect the shadow price of carbon emissions. We calibrate a Melitz-type model, extended by firms’ emissions and abatement decisions using data on aggregate output, trade and emissions. The parameter estimates are estimated from the German Manufacturing Census. The quantitative model allows us to recover a measure of how regulatory stringency evolved in the EU and Germany in terms of an implicit carbon price paid on emissions. This price reflects energy and carbon prices in addition to command-and-control measures and decreased from 2005 to 2019 in most sectors – both in Germany and other EU countries. The trend is more pronounced in Germany than in the rest of the EU. In counterfactual analyses, we show that this intra-EU difference has substantially increased German industrial emissions. Had the EU experienced the same decrease in implicit carbon prices as Germany, German emissions would have been substantially lower. Germany has increasingly become a pollution have

MASTL promotes cell contractility and motility through kinase-independent signaling

Microtubule-associated serine/threonine-protein kinase-like (MASTL) is a mitosis-accelerating kinase with emerging roles in cancer progression. However, possible cell cycle-independent mechanisms behind its oncogenicity remain ambiguous. Here, we identify MASTL as an activator of cell contractility and MRTF-A/SRF (myocardin-related transcription factor A/serum response factor) signaling. Depletion of MASTL increased cell spreading while reducing contractile actin stress fibers in normal and breast cancer cells and strongly impairing breast cancer cell motility and invasion. Transcriptome and proteome profiling revealed MASTL-regulated genes implicated in cell movement and actomyosin contraction, including Rho guanine nucleotide exchange factor 2 (GEF-H1, ARHGEF2) and MRTF-A target genes tropomyosin 4.2 (TPM4), vinculin (VCL), and nonmuscle myosin IIB (NM-2B, MYH10). Mechanistically, MASTL associated with MRTF-A and increased its nuclear retention and transcriptional activity. Importantly, MASTL kinase activity was not required for regulation of cell spreading or MRTF-A/SRF transcriptional activity. Taken together, we present a previously unknown kinase-independent role for MASTL as a regulator of cell adhesion, contractility, and MRTF-A/SRF activity. [Abstract copyright: © 2020 Taskinen et al.

What drives carbon emissions in German manufacturing: Scale, technique or composition?

Carbon emissions from German manufacturing have increased over the past decade, while carbon intensity (emissions per Euro of gross output) has declined only slightly. We decompose changes in emissions between 2005 and 2017 into scale, composition (changes in the mix of goods produced) and technology (emission factors of production) effects. We find evidence that the production composition in the German manufacturing sector is increasingly shifting towards less carbonintensive products. However, we also find evidence to suggest that the energy intensity of production has increased. These results are largely driven by a few energy intensive sectors

Diverse functions of myosin VI elucidated by an isoform-specific α-helix domain.

Myosin VI functions in endocytosis and cell motility. Alternative splicing of myosin VI mRNA generates two distinct isoform types, myosin VI(short) and myosin VI(long), which differ in the C-terminal region. Their physiological and pathological roles remain unknown. Here we identified an isoform-specific regulatory helix, named the α2-linker, that defines specific conformations and hence determines the target selectivity of human myosin VI. The presence of the α2-linker structurally defines a new clathrin-binding domain that is unique to myosin VI(long) and masks the known RRL interaction motif. This finding is relevant to ovarian cancer, in which alternative myosin VI splicing is aberrantly regulated, and exon skipping dictates cell addiction to myosin VI(short) in tumor-cell migration. The RRL interactor optineurin contributes to this process by selectively binding myosin VI(short). Thus, the α2-linker acts like a molecular switch that assigns myosin VI to distinct endocytic (myosin VI(long)) or migratory (myosin VI(short)) functional roles
