Die Entwicklung des aggregierten Privatvermögens und seine Verteilung in Deutschland seit 1970
(2002)
Die hier vorgestellte Untersuchung des Vermögens privater Haushalte als ein möglicher Indikator für den Wohlstand einer Gesellschaft hat für die Bundesrepublik Deutschland einen starken Anstieg der Vermögen seit 1970 aufgezeigt. Dies gilt sowohl für die makroökonomischen Resultate der Finanzierungsrechnung der Deutschen Bundesbank als auch für die mikroökonomischen Ergebnisse der Einkommens- und Verbrauchsstichproben des Statistischen Bundesamts. Allerdings werden auch wesentliche Unterschiede im Aussagegehalt der einzelnen Datensätze deutlich. Während die Finanzierungsrechnung eine Steigerung des Nettovermögens um 808 Prozent in 27 Jahren aufweist (von 1,3 Billionen DM im Jahr 1970 auf 12,1 Billionen DM im Jahr 1997) lautet der entsprechende Prozentwert auf der Berechnungsbasis der Einkommens- und Verbrauchsstichproben nur 280 Prozent in 25 Jahren bei einer wesentlich niedrigeren Gesamthöhe in späteren Untersuchungen (von 2,2 Billionen DM im Jahr 1973 auf nur 8,3 Billionen DM im Jahr 1998). Die Untersuchung der Daten der EVS hat aufgezeigt, welch große Bedeutung das Immobilienvermögen für die Vermögenssituation der privaten Haushalte hat. Allerdings ist es nicht so, dass alle Haushalte über Eigentum an Grund- und Hausbesitz verfügen. In Westdeutschland hat es zwar eine starke Steigerungen der Eigentümerquote seit 1961 gegeben. Seit 1993 ist jedoch eine Stagnation bei etwa 50 Prozent zu konstatieren. Die Analyse der Vermögensverteilung nur bezogen auf die westdeutschen Haushalte hat im Zeitraum von 1973 bis 1993 eine abnehmende Konzentration sowohl bei der Betrachtung der Anteile einzelner Haushaltsquintile am Nettogesamtvermögen als auch bei der Analyse des Gini-Koeffizienten ergeben. Allerdings hat sich dieser Trend in den Jahren bis 1998 nicht weiter fortgeführt. Für das Jahr 1998 ist in Westdeutschland feststellbar, dass die unteren 40 Prozent der Haushalte über praktisch kein Vermögen verfügen, während das oberste Quintil über 60 Prozent des Gesamtvermögens aufweisen kann. Für Ostdeutschland sind starke Anpassungstendenzen hin zu den Werten der westdeutschen Bundesländer festzustellen. Dies betrifft einerseits die absolute Höhe der Vermögenswerte, auch wenn diese bisher nur 38 Prozent des entsprechenden Wertes westdeutscher Haushalte bei einer Betrachtung der Durchschnittswerte je Haushalte im Jahr 1998 erreichen. Andererseits ist auch die Eigentümerquote an Haus- und Grundbesitz nach der Wiedervereinigung stark angestiegen. Durch dieses Immobilieneigentum auf breiterer Basis wird die Ungleichheit der Vermögensverteilung in Ostdeutschland im Zeitablauf etwas verringert, so dass der Gini-Koeffizient in den Jahren von 1993 zu 1998 leicht gesunken ist. Jedoch kann auch für die neuen Bundesländer festgestellt werden, dass die unteren 40 Prozent der Haushalte über praktisch kein Vermögen verfügen, während das oberste Quintil ostdeutscher Haushalte sogar über 70 Prozent des Gesamtvermögens aufweisen kann. Feststellbar ist weiterhin eine hohe Übereinstimmung der Vermögensverteilung in Ost- und Westdeutschland. Sowohl die Vermögensverteilung auf der Basis der Quintilswerte als auch die Resultate der Gini-Koeffizienten weisen ähnliche Ergebnisse auf, wobei eine starke Angleichungstendenz zwischen beiden Landesteilen gegeben ist. Diese Ähnlichkeit der Ergebnisse kann nur als erstaunlich bezeichnet werden, wenn man bedenkt, dass beide Landesteile für über 40 Jahre unterschiedlichen wirtschaftspolitischen Leitbildern gefolgt sind – die Bundesrepublik Deutschland der sozialen Marktwirtschaft und die Deutsche Demokratische Republik der sozialistischen Planwirtschaft.
Die Struktur der Gesetzlichen Rentenversicherung (GRV) in der Bundesrepublik Deutschland ist grundsätzlich geändert worden. Die Bundesregierung hat die Einführung einer zusätzlichen privaten Alterssicherung auf freiwilliger Basis beschlossen. Hierdurch soll ein Kapitalstock gebildet werden, der die Leistungen der GRV ergänzt. Zur Förderung dieser Systemänderung der Alterssicherung werden umfangreiche fiskalische Unterstützungsmaßnahmen eingeführt. Im Rahmen des hier vorliegenden Beitrags wird auf die besondere Situation der Familien mit Kindern eingegangen. Im zweiten Abschnitt wird untersucht, inwieweit Familien mit Kindern in den letzten zehn Jahren in Deutschland in der Lage waren, privates Vermögen aufzubauen. Im dritten Abschnitt werden die beabsichtigten Änderungen des Systems der gesetzlichen Rentenversicherung in den Grundzügen dargestellt, und es wird ein Überblick über die geplanten fiskalischen Fördermaßnahmen gegeben. Im abschließenden vierten Abschnitt wird eine Bewertung der Änderungen vor allem in Bezug auf die Situation von Familien versucht.
Objectives: Regarding reactogenicity and immunogenicity, heterologous COVID-19 vaccination regimens are considered as an alternative to conventional immunization schemes.
Methods: Individuals receiving either heterologous (ChAdOx1-S [AstraZeneca, Cambridge, UK]/BNT162b2 [Pfizer-BioNTech, Mainz, Germany]; n = 306) or homologous (messenger RNA [mRNA]-1273 [Moderna, Cambridge, Massachusetts, USA]; n = 139) vaccination were asked to participate when receiving their second dose. Reactogenicity was assessed after 1 month, immunogenicity after 1, 3, and/or 6 months, including a third dose, through SARS-CoV-2 antispike immunoglobulin G, surrogate virus neutralization test, and a plaque reduction neutralization test against the Delta (B.1.167.2) and Omicron (B.1.1.529; BA.1) variants of concern.
Results: The overall reactogenicity was lower after heterologous vaccination. In both cohorts, SARS-CoV-2 antispike immunoglobulin G concentrations waned over time with the heterologous vaccination demonstrating higher neutralizing activity than homologous mRNA vaccination after 3 months to low neutralizing levels in the Delta plaque reduction neutralization test after 6 months. At this point, 3.2% of the heterologous and 11.4% of the homologous cohort yielded low neutralizing activity against Omicron. After a third dose of an mRNA vaccine, ≥99% of vaccinees demonstrated positive neutralizing activity against Delta. Depending on the vaccination scheme and against Omicron, 60% to 87.5% of vaccinees demonstrated positive neutralizing activity.
Conclusion: ChAdOx1-S/BNT162b2 vaccination demonstrated an acceptable reactogenicity and immunogenicity profile. A third dose of an mRNA vaccine is necessary to maintain neutralizing activity against SARS-CoV-2. However, variants of concern-adapted versions of the vaccines would be desirable.
Aims: Carotid intima media thickness (CIMT) predicts cardiovascular (CVD) events, but the predictive value of CIMT change is debated. We assessed the relation between CIMT change and events in individuals at high cardiovascular risk.
Methods and results: From 31 cohorts with two CIMT scans (total n = 89070) on average 3.6 years apart and clinical follow-up, subcohorts were drawn: (A) individuals with at least 3 cardiovascular risk factors without previous CVD events, (B) individuals with carotid plaques without previous CVD events, and (C) individuals with previous CVD events. Cox regression models were fit to estimate the hazard ratio (HR) of the combined endpoint (myocardial infarction, stroke or vascular death) per standard deviation (SD) of CIMT change, adjusted for CVD risk factors. These HRs were pooled across studies.
In groups A, B and C we observed 3483, 2845 and 1165 endpoint events, respectively. Average common CIMT was 0.79mm (SD 0.16mm), and annual common CIMT change was 0.01mm (SD 0.07mm), both in group A. The pooled HR per SD of annual common CIMT change (0.02 to 0.43mm) was 0.99 (95% confidence interval: 0.95–1.02) in group A, 0.98 (0.93–1.04) in group B, and 0.95 (0.89–1.04) in group C. The HR per SD of common CIMT (average of the first and the second CIMT scan, 0.09 to 0.75mm) was 1.15 (1.07–1.23) in group A, 1.13 (1.05–1.22) in group B, and 1.12 (1.05–1.20) in group C.
Conclusions: We confirm that common CIMT is associated with future CVD events in individuals at high risk. CIMT change does not relate to future event risk in high-risk individuals.
Aims: Averaged measurements, but not the progression based on multiple assessments of carotid intima-media thickness, (cIMT) are predictive of cardiovascular disease (CVD) events in individuals. Whether this is true for conventional risk factors is unclear.
Methods and results: An individual participant meta-analysis was used to associate the annualised progression of systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol with future cardiovascular disease risk in 13 prospective cohort studies of the PROG-IMT collaboration (n = 34,072). Follow-up data included information on a combined cardiovascular disease endpoint of myocardial infarction, stroke, or vascular death. In secondary analyses, annualised progression was replaced with average. Log hazard ratios per standard deviation difference were pooled across studies by a random effects meta-analysis. In primary analysis, the annualised progression of total cholesterol was marginally related to a higher cardiovascular disease risk (hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.00 to 1.07). The annualised progression of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol was not associated with future cardiovascular disease risk. In secondary analysis, average systolic blood pressure (HR 1.20 95% CI 1.11 to 1.29) and low-density lipoprotein cholesterol (HR 1.09, 95% CI 1.02 to 1.16) were related to a greater, while high-density lipoprotein cholesterol (HR 0.92, 95% CI 0.88 to 0.97) was related to a lower risk of future cardiovascular disease events.
Conclusion: Averaged measurements of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol displayed significant linear relationships with the risk of future cardiovascular disease events. However, there was no clear association between the annualised progression of these conventional risk factors in individuals with the risk of future clinical endpoints.
As one of the first Direct Acting Antivirals (DAA), the protease inhibitor Telaprevir (TVR) was available in the European Union from 9/2011 until 9/2016 as a new treatment option for chronic Hepatitis C.Aim. To assess the implementation of therapy stopping rules or shortening of the treatment and their impact on sustained virological response (SVR), as well as the safety and efficacy of the TVR-based therapy during routine daily treatment of patients in Germany.Materials and Methods. 802 patients were assessed (272 treatment naïve, 520 pre-treated) in the noninterventional, multi-center study.Results. 56.6 % of the patients achieved SVR. SVR rate was higher in patients with relapse after previous treatment (68.0 %) than in patients with a previous null-response (31.1 %) and in previously untreated patients (58.1 %). Stopping rule conditions were fulfilled by 3.2 % of patients and it was implemented in 65.4 % of these. 34.3 % of the patients fulfilled the conditions for a therapy shortening. This rule was adhered to in 48.4 % of these, in 34.5 % it was not adhered to. Thus recommendations were not always being followed. Therapy shortening was considered more frequently in previously untreated (54.8 %) than for previously treated patients (24.2 %). Stopping rule application but not shortened treatment reduced therapy costs.Conclusion. The TVR-based therapy represented a breakthrough at that time. Further DAAs have been added as therapeutic options since, increasing the complexity of treatment choice and correct implementation. They represent both an opportunity and a challenge for all those involved.As one of the first Direct Acting Antivirals (DAA), the protease inhibitor Telaprevir (TVR) was available in the European Union from 9/2011 until 9/2016 as a new treatment option for chronic Hepatitis C.Aim.

Previous studies in developing Xenopus and zebrafish reported that the phosphate transporter slc20a1a is expressed in pronephric kidneys. The recent identification of SLC20A1 as a monoallelic candidate gene for cloacal exstrophy further suggests its involvement in the urinary tract and urorectal development. However, little is known of the functional role of SLC20A1 in urinary tract development. Here, we investigated this using morpholino oligonucleotide knockdown of the zebrafish ortholog slc20a1a. This caused kidney cysts and malformations of the cloaca. Moreover, in morphants we demonstrated dysfunctional voiding and hindgut opening defects mimicking imperforate anus in human cloacal exstrophy. Furthermore, we performed immunohistochemistry of an unaffected 6-week-old human embryo and detected SLC20A1 in the urinary tract and the abdominal midline, structures implicated in the pathogenesis of cloacal exstrophy. Additionally, we resequenced SLC20A1 in 690 individuals with bladder exstrophy-epispadias complex (BEEC) including 84 individuals with cloacal exstrophy. We identified two additional monoallelic de novo variants. One was identified in a case-parent trio with classic bladder exstrophy, and one additional novel de novo variant was detected in an affected mother who transmitted this variant to her affected son. To study the potential cellular impact of SLC20A1 variants, we expressed them in HEK293 cells. Here, phosphate transport was not compromised, suggesting that it is not a disease mechanism. However, there was a tendency for lower levels of cleaved caspase-3, perhaps implicating apoptosis pathways in the disease. Our results suggest SLC20A1 is involved in urinary tract and urorectal development and implicate SLC20A1 as a disease-gene for BEEC.
This investigation of the wealth of private households as a possible indicator for the prosperity of a society indicated a strong increase in wealth for the Federal Republic of Germany since 1970. This applies both to the macro-economic results of the financial accounting of the Deutsche Bundesbank and to the micro-economic results of the Income and Consumption Surveys of the Federal Statistical Office. However, substantial differences become clear in the content expressed by these two different sets of data. While the financial accounting of the Deutsche Bundesbank shows an increase of net assets of around 808 per cent over 27 years (from 1.3 trillion DM in the year 1970 to 12.1 trillion DM in 1997), calculations on the basis of the Income and Consumption Surveys yield a corresponding value of only 280 per cent in a 25-year period, with a substantially lower overall magnitude in later investigations (from 2.2 trillion DM in 1973 to only 8.3 trillion DM in 1998). Investigation of the EVS data pointed out the great importance of property for the wealth situation of private households. However, not every household has property in the form of housing and real estate. In West Germany, ownership rates have increased substantially since 1962. However, since 1993 these rates have stagnated at about 50 per cent. The analysis of the distribution of wealth for West German households yielded a decline in the concentration of wealth in the period from 1973 to 1993, both in terms of the shares of total wealth held by individual quintiles of households, and as expressed by the Gini coefficients. However, this trend did not continue in the years between 1993 and 1998. For the year 1998 it can be determined that the lowest 40 per cent of households in West Germany had practically no wealth, while the highest quintile claimed over 60 per cent of total assets. For East Germany, strong tendencies are established toward adapting to the values in the West German Länder. This concerns first the absolute level of net assets, even though in 1998 these amounted to just 38 per cent of the analogous value in West German households, in terms of the average value per household. Similarly, the ownership rates of housing and real estate also rose dramatically after reunification. The inequality of the distribution of wealth in East Germany was reduced somewhat by this broader basis of real-estate ownership over the course of time, such that the Gini coefficient decreased slightly in the period from 1993 to 1998. However, it is also true for the new Länder in the Federal Republic that the lowest 40 per cent of households have practically no wealth, while the highest quintile of East German households claim over 70 per cent of total assets, even higher than its share in West Germany. Furthermore, the distribution of wealth is remarkably congruous in East and West Germany. Both the distribution of wealth as expressed by the quintile values and the results of the Gini coefficients yield similar results, whereby the trend in both regions is toward convergence. The similarity of these results must be regarded as nothing less than amazing, considering that the two regions followed different economic models for over forty years: the social free-market economy (Soziale Marktwirtschaft) in the Federal Republic of Germany, and the socialist planned economy (Sozialistische Planwirtschaft) in the German Democratic Republic.
The structure of the compulsory pension system (CPS) in the Federal Republic of Germany has been changed fundamentally. The federal government has decided to introduce a private pension system on a voluntary basis. The payments to this voluntary system are to constitute a capital stock to supplement the payments of the compulsory pension system. Comprehensive fiscal subsidies will be introduced to support this change to the pension system. This paper discusses the special situation of families with children. The second section investigates the extent to which families with children were able to accumulate private wealth in the last ten years in Germany. In the third section the main features of the intended changes to the compulsory pension system are described, and an overview of the planned fiscal subsidies is provided. In the fourth and final section we attempt to evaluate the changes with particular attention to the situation of families.
Wirkungen von Heilpflanzen, Gewürzen, Tees und Lebensmitteln werden in der Naturheilkunde seit der Antike genutzt. Pharmakologisch wirksam sind in der Regel nur die sekundären Pflanzeninhaltsstoffe. Diese in den oft aus vielen Bestandteilen zusammengesetzten Naturstoffen aufzuspüren und ihren molekularbiologischen Wirkungsmechanismus im Körper aufzuklären, ist das Ziel eines Forschungsnetzwerks am Frankfurter ZAFES (Zentrum für Arzneimittelforschung, -Entwicklung und -Sicherheit). So konnten Pharmazeuten und Kliniker gemeinsam herausfinden, wie ein Bestandteil des Rotweins, das Resveratrol, vor Darmkrebs schützt. Die Inhaltsstoffe von Salbei und Rosmarin bieten vielversprechende Ausgangspunkte für neue Medikamente gegen Altersdiabetes. Weihrauch, Myrte und Johanniskraut enthalten Wirkstoffe, die Schlüsselenzyme für Entzündungsreaktionen – etwa bei rheumatischen Beschwerden – hemmen.
