Perception and Reality—Economic Inequality as a Driver of Populism?

Abstract Can the rise of populism be explained by the growing chasm between rich and poor? With regard to Germany, such a causal relationship must be rejected. Income distribution in Germany has been very stable since 2005, and people’s knowledge on actual inequality and economic development is limited: inequality and unemployment are massively overestimated. At the same time, a persistently isolationist and xenophobic group with diverse concerns and preferences has emerged within the middle classes of society that riggers support for populist parties. This mood is based on welfare chauvinism against immigration rather than on a general criticism of distribution. Since the immigration of recent years will inevitably affect the relevant indicators concerning distribution, an open, cautious but less heated approach is needed in the debate on the future of the welfare state. In order to address and take the local concerns of citizens seriously, an increased exchange with public officials on the ground is needed.

Trend analysis and regional tumor incidence in Germany for testicular cancer between 2003 and 2014.

Testicular germ cell tumor (TGCT) is one the most common solid tumors in men between the age of 15 and 35 with an overall incidence rate of 1-1.5 %. Epidemiologic studies have demonstrated different incidence patterns in western civilized countries with overall rising incidence trends. To analyze differences in regional tumor incidence rates for TGCT and perform a trend analysis for TGCT between 2003 and 2014 in Germany. TGCT cases in Germany which were diagnosed between 2003 and 2014 were provided by the Robert-Koch-Institute, Berlin. For statistical analysis, cluster and spatial scan tests according to Kulldorff were used for cases with seminoma and non-seminoma. Results are presented in administrative districts and graphically illustrated. We performed a trend-analysis in order to evaluate age-adjusted incidence trends in Germany. Tests were two-sided with a level of significance of α=0.05. In total we included 35,066 patients. Overall, 22,634 cases had newly diagnosed seminoma and 12,432 were diagnosed as non-seminoma. Maximum incidence of seminoma and non-seminoma was observed for age-group 38-40 years and 26-28 years, respectively. No second peak for the incidences of seminoma and non-seminoma with respect to age were observed. Cluster analysis revealed areas with high and low incidence rates as well as slightly different spatial distribution in Germany between seminoma and nonseminoma. Furthermore, there was no significant increase in age-adjusted incidence rates over the reviewed time period in both cohorts. In this study differences in reginal tumor incidence rates for seminoma and non-seminoma are reported with both tumor entities revealing distinct clusters. Furthermore, tumor incidence trends for seminoma and nonseminoma between 2003 and 2014 were stable which might indicate the beginning of a plateau phase for TGCT incidence rates in Germany. In this analysis we were able to identify regions with significantly higher tumor incidence rates for both seminoma and non-seminoma which were specific for these two subtypes. Furthermore, trend analysis revealed a steady incidence rate for testicular cancer in Germany.

Inequality in Germany: A Macroeconomic Perspective

Household surveys such as the German Socio-Economic Panel (SOEP) tend to underestimate income and wealth inequality. The research methodology developed by Thomas Piketty et al. therefore analyses official tax statistics in order to more accurately determine the inequality between the people at the top of the income and wealth distribution scale and the rest of the population. However, Piketty’s methodology underestimates the rise in inequality in Germany since the turn of the millennium due to the fact that companies are retaining a significant percentage of their rising profits which are therefore not recorded as private household income. We show how the specific pattern of income distribution in Germany has contributed to the country’s large and persistent current account surplus, thereby contributing to macroeconomic instability at the international level. We note that addressing economic inequality in Germany politically through wealth and inheritance taxes faces the resistance of powerful lobby groups including family-owned businesses (the German Mittelstand).

Legitimacy and field development: Electricity transition(s) in Germany

The paper draws on recent developments in the field of electricity generation and distribution in Germany to outline some basic assumptions on how legitimation strategies are framed and differ between emerging and stable action fields. We analyze decentralized forms of electricity generation and distribution. Pioneers of this development seized opportunities connected with broad institutional changes to discredit the status quo and work out legitimations for their new model of how to generate and distribute electricity. Just like skilled actors in stable fields working on adaptation strategies to changing environments, the ones in emerging fields engaged in working out new search strategies, built coalitions, undertook collective action, and established affiliations with recognized authorities and elites. However, unlike skilled actors in stable fields, those in the emerging ones, could not build on established routines. Instead, they drew on logics from outside their field and emphasized the benefits of their activities for society at large. Our analysis shows how actors legitimate novel organizational forms in emerging fields vs. the attempts of incumbent actors in mature fields to preserve their position in a contentious period. Theories of social change should explicitly account for field context.

Inequality in turbulent times: income distribution in Germany and Britain, 1900–50

AbstractUsing social tables, this article provides new data on inequality in Germany and Britain on an annual basis for the first half of the twentieth century. Inequality trends in these two countries tended to follow opposite patterns. The decline in inequality in Germany was interrupted during the First World War and the Nazi period, while in Britain the reversal took place between the end of the First World War and the Great Depression. Results show that the drop in inequality during the twentieth century in Europe did not follow secular trends, thus supporting the notion of inequality cycles.

Thermal experiments with the Asian bush mosquito (Aedes japonicus japonicus) (Diptera: Culicidae) and implications for its distribution in Germany

BackgroundAs ectothermic animals, temperature influences insects in almost every aspect. The potential disease spreading Asian bush mosquito (Aedes japonicus japonicus) is native to temperate East Asia but invasive in several parts of the world. We report on the previously poorly understood temperature-dependence of its life history under laboratory conditions to understand invasion processes and to model temperature niches.ResultsTo evaluate winter survival, eggs were exposed between 1 day and 14 days to low temperatures (5 °C, 0 °C, -5 °C and -9 °C). Hatching success was drastically decreased after exposure to 0 °C and -5 °C, and the minimal hatching success of 0% was reached at -9 °C after two days. We then exposed larvae to 14 temperatures and assessed their life trait parameters. Larval survival to adulthood was only possible between 10 °C and 31 °C. Based on this, we modelled the optimal (25 °C), minimal (7 °C) and maximal (31 °C) temperature for cumulative female survival. The time to adult emergence ranges from 12 days to 58 days depending on temperature. We used an age-at-emergence-temperature model to calculate the number of potential generations per year for the Asian bush mosquito in Germany with an average of 4.72 potential generations. At lower temperatures, individuals grew larger than at higher temperatures with female R1 length ranging from 3.04 ± 0.1 mm at 31 °C to 4.26 ± 0.2 mm at 15 °C.ConclusionsReduced egg hatch after exposure to sub-zero temperatures prohibits the establishment of the Asian bush mosquito in large parts of Germany. Larval overwintering is not possible at temperature ≤ 5 °C. The many potential generations displayed per year may contribute to the species’ invasion success. This study on the thermal ecology of the Asian bush mosquito adds to our knowledge on the temperature dependence of the species and data could be incorporated in epidemiological and population dynamic modelling.

Looking for the Missing Rich: Tracing the Top Tail of the Wealth Distribution

We analyze the top tail of the wealth distribution in Germany, France, and Spain based on the first and second wave of the Household Finance and Consumption Survey (HFCS). Since top wealth is likely to be underrepresented in household surveys, we integrate big fortunes from rich lists, estimate a Pareto distribution, and impute the missing rich. In addition to the Forbes list, we rely on national rich lists since they represent a broader base for the big fortunes in those countries. As a result, the top percentile share of household wealth in Germany jumps up from 24 percent to 31 percent in the first and from 24 to 33 percent in the second wave after top wealth imputation. For France and Spain, we find only a small effect of the imputation since rich households are better captured in the survey.

Reasons for self-testing—beyond the passive users. Results from a nationwide sample in Germany

The aims of this study were to investigate (1) the personal reasons for using a self-test, (2) the decisive motives for self-testing, and (3) why a self-test was preferred over a conventional diagnosis by a health professional. Participants were invited to an online survey in batches representative of the age and gender distribution in Germany. The research questions were investigated with open questions and questions with given responses. Qualitative content analysis was conducted based on the method described by Mayring. Overall, 980 personal reasons for conducting 709 self-tests were indicated by 505 self-testers, which were assigned to 13 main categories with 32 sub-categories. The two most frequently stated personal reasons for self-testing were ‘uncertainty/reassurance’ and ‘risk perception’ (e.g. hereditary risks, previous diseases). The decisive reason for self-testing was strongly associated with the disease the user expected to detect. Self-tests were preferred over a diagnosis by a health professional because of practical advantages. The majority of the German testers actively sought a self-test. Self-testers’ follow-up behaviour and their emotional perceptions need to be investigated.

Mitochondrial DNA provides evidence of a double origin for the stone crayfish Austropotamobius torrentium in the Elbe basin

• Native status of stone crayfish in the Elbe basin has been challenged in the past. • We studied genetic variation of representative populations from this region. • Haplotype variation of the mitochondrial COI gene confirms species’ double origin. • Stone crayfish probably colonised the Elbe basin from the Danube basin naturally. • One population in eastern Bohemia was introduced by men, probably from Slovenia. The stone crayfish Austropotamobius torrentium is the smallest native European crayfish, restricted to central and southeast Europe. Northeast boundary of its range is located within the Elbe basin but considerable uncertainties existed regarding its status in this area. Until recently, known stone crayfish populations in the Elbe basin were very scattered and human translocations have been implicated in such distribution pattern. Discoveries of additional populations in the Czech Republic and Saxony (east Germany) nevertheless suggest that the species may have been more widespread there. We provide data on genetic variation (based on 181 sequences of the mitochondrial COI gene) of 20 representative populations from the Elbe basin (both from the Czech Republic and Saxony). We tested whether the haplotype variation is consistent with a scenario of natural dispersal or whether long-range transport has been involved. All analysed individuals from the easternmost, geographically isolated Czech stone crayfish population carried a haplotype previously recorded only in Slovenia and its vicinity; it is therefore likely that such population has been introduced by humans. In contrast, all remaining studied populations were dominated by a haplotype widespread in adjacent regions of species’ distribution in Germany, and additional haplotypes differing by point mutations were occasionally detected. This is consistent with a scenario of a postglacial colonization from Bavaria (southeast Germany). Our study provides evidence for a double origin of stone crayfish populations in the upper Elbe basin, with both natural and anthropogenic factors likely affecting the present diversity and distribution of this species.

Host-feeding patterns of mosquito species in Germany.

BackgroundMosquito-borne pathogens are of growing importance in many countries of Europe including Germany. At the same time, the transmission cycles of most mosquito-borne pathogens (e.g. viruses or filarial parasites) are not completely understood. There is especially a lack of knowledge about the vector capacity of the different mosquito species, which is strongly influenced by their host-feeding patterns. While this kind of information is important to identify the relevant vector species, e.g. to direct efficient control measures, studies about the host-feeding patterns of mosquito species in Germany are scarce and outdated.MethodsBetween 2012 and 2015, 775 blood-fed mosquito specimens were collected. Sampling was conducted with Heavy Duty Encephalitis Vector Survey traps, Biogents Sentinel traps, gravid traps, hand-held aspirators, sweep nets, and human-bait collection. The host species for each mosquito specimen was identified with polymerase chain reactions and subsequent Sanger sequencing of the cytochrome b gene.ResultsA total of 32 host species were identified for 23 mosquito species, covering 21 mammalian species (including humans) and eleven bird species. Three mosquito species accounted for nearly three quarters of all collected blood-fed mosquitoes: Aedes vexans (363 specimens, 46.8 % of all mosquito specimens), Culex pipiens pipiens form pipiens (100, 12.9 %) and Ochlerotatus cantans (99, 12.8 %). Non-human mammals dominated the host species (572 specimens, 73.8 % of all mosquito specimens), followed by humans (152, 19.6 %) and birds (51, 6.6 %). The most common host species were roe deer (Capreolus capreolus; 258 mosquito specimens, 33.3 % of all mosquito specimens, 65 % of all mosquito species), humans (Homo sapiens; 152, 19.6 %, 90 %), cattle (Bos taurus; 101, 13.0 %, 60 %), and wild boar (Sus scrofa; 116, 15.0 %, 50 %). There were no statistically significant differences in the spatial-temporal host-feeding patterns of the three most common mosquito species.ConclusionsAlthough the collected blood-fed mosquito species had a strong overlap of host species, two different host-feeding groups were identified with mosquito species feeding on (i) non-human mammals and humans or (ii) birds, non-human mammals, and humans, which make them potential vectors of pathogens only between mammals or between mammals and birds, respectively. Due to the combination of their host-feeding patterns and wide distribution in Germany, Cx. pipiens pipiens form pipiens and Cx. torrentium are potentially most important vectors for pathogens transmitted from birds to humans and the species Ae. vexans for pathogens transmitted from non-human mammals to humans. Finally, the presented study indicated a much broader host range compared to the classifications found in the literature for some of the species, which highlights the need for studies on the host-feeding patterns of mosquitoes to further assess their vector capacity and the disease ecology in Europe.Electronic supplementary materialThe online version of this article (doi:10.1186/s13071-016-1597-z) contains supplementary material, which is available to authorized users.

Comparison of single- and multi-scale models for the prediction of the Culicoides biting midge distribution in Germany.

This study analysed Culicoides presence-absence data from 46 sampling sites in Germany, where monitoring was carried out from April 2007 until May 2008. Culicoides presence-absence data were analysed in relation to land cover data, in order to study whether the prevalence of biting midges is correlated to land cover data with respect to the trapping sites. We differentiated eight scales, i.e. buffer zones with radii of 0.5, 1, 2, 3, 4, 5, 7.5 and 10 km, around each site, and chose several land cover variables. For each species, we built eight single-scale models (i.e. predictor variables from one of the eight scales for each model) based on averaged, generalised linear models and two multiscale models (i.e. predictor variables from all of the eight scales) based on averaged, generalised linear models and generalised linear models with random forest variable selection. There were no significant differences between performance indicators of models built with land cover data from different buffer zones around the trapping sites. However, the overall performance of multi-scale models was higher than the alternatives. Furthermore, these models mostly achieved the best performance for the different species using the index area under the receiver operating characteristic curve. However, as also presented in this study, the relevance of the different variables could significantly differ between various scales, including the number of species affected and the positive or negative direction. This is an even more severe problem if multi-scale models are concerned, in which one model can have the same variable at different scales but with different directions, i.e. negative and positive direction of the same variable at different scales. However, multi-scale modelling is a promising approach to model the distribution of Culicoides species, accounting much more for the ecology of biting midges, which uses different resources (breeding sites, hosts, etc.) at different scales.

The Top Tail of the Wealth Distribution in Germany, France, Spain, and Greece

We analyze the top tail of the wealth distribution in Germany, France, Spain, and Greece based on the Household Finance and Consumption Survey (HFCS). Since top wealth is likely to be underrepresented in household surveys we integrate the big fortunes from rich lists, estimate a Pareto distribution, and impute the missing rich. Instead of the Forbes list we mainly rely on national rich lists since they represent a broader base for the big fortunes. As a result, the top percentile share of household wealth in Germany jumps up from 24 percent in the HFCS alone to 33 percent after top wealth imputation. For France and Spain we find only a small effect of the imputation since rich households are better captured in the survey. The results for Greece are ambiguous since the data do not show clear concentration patterns.

Disulfiram in outpatient treatment of alcohol dependency

The alcohol deterrent drug disulfiram plays a minor role in the treatment of alcohol dependency in Germany. The study looks at the efficacy, tolerability and feasibility of a disulfiram outpatient treatment program in a German psychiatric hospital. Data from 190 outpatients with alcohol dependency, who had participated in a disulfiram therapy program at the psychiatric outpatient department over a period of 10 years, were analyzed with respect to efficacy and tolerability. To test for predictors, independent variables and treatment success as a dependent variable a logistic regression was carried out. After 1 year 24.2 % of the patients maintained alcohol abstinence while 55 % had had an alcohol relapse despite being in the disulfiram program. No severe complications were observed under disulfiram treatment. Therapy success was largely related to participating in treatment-specific group therapy. Disulfiram proved to be a well-tolerated medication as part of multimodal therapy of alcohol dependency. The disulfiram program was easily integrated into other health service treatment. Approximately one quarter of patients who had had an unfavorable course before, achieved abstinence, while participation in group therapy was a major predictor of treatment success. Disulfiram is a medication, which in the context of a psychosocial treatment concept, should receive a wider distribution in Germany.

Authorised allergen products for intracutaneous testing may no longer be available in Germany: Allergy textbooks have to be re-written.

Background:Beside the skin prick test, the intracutaneous test represents the most important skin test method for detecting type-1 allergies. With the incorporation of European directives into national law, test allergens used for allergy diagnosis are deemed medicinal products within the meaning of the German Medicinal Products Act (Arzneimittelgesetz) and therefore require marketing authorisation for distribution in Germany. The high costs of acquiring and maintaining these authorisations have lead to no new finished intracutaneous test products being authorized in Germany for more than 20 years. Instead, most manufacturers have voluntarily withdrawn their existing marketing authorisations for intracutaneous test extracts. The last manufacturer to offer approved finished allergen products for intracutaneous tests recently announced that it would now cease production and distribution of these solutions.Methods:Research on the current European and German legislation; selective literature search in Medline, including national and international guidelines and Cochrane meta-analyses; licensing information on the Paul-Ehrlich-Institute homepage (www.pei.de) as well as in the Bundesanzeiger (Federal Gazette).Results:According to information on www.pei.de, marketing authorisations still existed as of 31.01.2015 for intracutaneous test solutions of six grass/cereal/herbal pollens, seven tree pollens, ten food allergens, twelve moulds and yeasts as well as two fungal mixtures, five house dust and storage mites and five animal epithelia/danders, all held by only one company in Germany. These marketing authorisations were granted between 16th March 1987 and 17th January 1992; more recent marketing authorisations do not exist.Conclusions:European legislation and the associated increase in production and licensing costs have already lead to numerous suppliers withdrawing their marketing authorisation for diagnostic test allergens — marketing authorisations for 443 diagnostic allergens were voluntarily withdrawn by manufacturers in 2013 alone. If the announced restrictions on the allergen portfolio go ahead, considerable problems in the management of allergy patients in Germany due to the discontinuation of the intracutaneous test are likely to be encountered. Moreover, the fact that a diagnostic procedure that has been established for decades seems set to disappear quite simply because all the requisite substances vanish from the market in one fell swoop may well be without parallel in modern medicine.The situation for skin prick test allergens is less dramatic, although, here again, the available range is becoming increasingly limited.

Country, cover or protection: what shapes the distribution of red deer and roe deer in the Bohemian Forest Ecosystem?

The Bohemian Forest Ecosystem encompasses various wildlife management systems. Two large, contiguous national parks (one in Germany and one in the Czech Republic) form the centre of the area, are surrounded by private hunting grounds, and hunting regulations in each country differ. Here we aimed at unravelling the influence of management-related and environmental factors on the distribution of red deer (Cervus elaphus) and roe deer (Capreolus capreolus) in this ecosystem. We used the standing crop method based on counts of pellet groups, with point counts every 100 m along 218 randomly distributed transects. Our analysis, which accounted for overdispersion as well as zero inflation and spatial autocorrelation, corroborated the view that both human management and the physical and biological environment drive ungulate distribution in mountainous areas in Central Europe. In contrast to our expectations, protection by national parks was the least important variable for red deer and the third important out of four variables for roe deer; protection negatively influenced roe deer distribution in both parks and positively influenced red deer distribution in Germany. Country was the most influential variable for both red and roe deer, with higher counts of pellet groups in the Czech Republic than in Germany. Elevation, which indicates increasing environmental harshness, was the second most important variable for both species. Forest cover was the least important variable for roe deer and the third important variable for red deer; the relationship for roe deer was positive and linear, and optimal forest cover for red deer was about 70% within a 500 m radius. Our results have direct implications for the future conservation management of deer in protected areas in Central Europe and show in particular that large non-intervention zones may not cause agglomerations of deer that could lead to conflicts along the border of protected, mountainous areas.

Myth or fact? The beauty premium across the wage distribution in Germany

We allow for differential effects of physical appearance across the wage distribution using a technique traditionally used in the finance literature. We find an average beauty premium of 2%–4% for women, which is concentrated at the bottom of the wage distribution. The average beauty premium for men is larger at 5%–7% and is present throughout the wage distribution. Both of these vary by education level. We find that differences in characteristics (such as age, family composition, labor market attributes, etc.) between beautiful and plain people contribute to the beauty premium identified using traditional regression models. Isolating this characteristic effect from the unexplained effect using decomposition techniques leads to smaller beauty premia.

Checklist of earthworms (Oligochaeta: Lumbricidae) from Germany.

A checklist of the German earthworm fauna (Oligochaeta: Lumbricidae) is presented, including published data, data from reports, diploma- and PhD- theses as well as unpublished data from museum collections, research institutions and private persons. Overall, 16,000 datasets were analyzed to produce the first German checklist of Lumbricidae. The checklist comprises 46 earthworm species from 15 genera and provides ecological information, zoogeographical distribution type and information on the species distribution in Germany. Only one species, Lumbricus badensis Michaelsen, 1907, is endemic to Germany, whereas 41% are peregrine. As there are 14 species occurring exclusively in the southern or eastern part of Germany, the species numbers in German regions increase from north to south.

Works Councils and Labour Productivity: Looking beyond the Mean

AbstractAfter more than 25 years of empirical investigation, the analysis of works council effects on establishment productivity is still an active field of economic research. I present first evidence for works council regression coefficients along the unconditional log labour productivity distribution in Germany. The highest (lowest) coefficients were found at the bottom (top) of the distribution, which suggests that works councils have the most beneficial effects at low levels of productivity. Importantly, coefficients are positive at each productivity level. The results shed light on a classical theoretical argument concerning moderating factors for the productivity effect of employee participation.

Age of onset in chronic diseases: new method and application to dementia in Germany

BackgroundAge of onset is an important outcome to characterize a population with a chronic disease. With respect to social, cognitive, and physical aspects for patients and families, dementia is especially burdensome. In Germany, like in many other countries, it is highly prevalent in the older population and imposes enormous efforts for caregivers and society.MethodsWe develop an incidence-prevalence-mortality model to derive the mean and variance of the age of onset in chronic diseases. Age- and sex-specific incidence and prevalence of dementia is taken from published values based on health insurance data from 2002. Data about the age distribution in Germany in 2002 comes from the Federal Statistical Office.ResultsMean age of onset of a chronic disease depends on a) the age-specific incidence of the disease, b) the prevalence of the disease, and c) the age distribution of the population. The resulting age of onset of dementia in Germany in 2002 is 78.8 ± 8.1 years (mean ± standard deviation) for men and 81.9 ± 7.6 years for women.ConclusionsAlthough incidence and prevalence of dementia in men are not greater than in women, men contract dementia approximately three years earlier than women. The reason lies in the different age distributions of the male and the female population in Germany.

Effective taxation of top incomes in Germany

We exploit an exhaustive administrative dataset that includes the individual tax returns of all households in the top percentile of the income distribution in Germany to pin down the effective income taxation of households with very high incomes. Taking tax base erosion into account, we find that the top percentile of the income distribution pays an effective average tax rate of 30.5 per- cent and contributes more than a quarter of total income tax revenue. Within the top percentile, the effective average tax rate is first increasing and then decreasing with income. Since the 1990s, ef- fective average tax rates for the German super rich have fallen by about a third, with major reduc- tions occurring in the wake of the personal income tax reform of 2001-2005. As a result, the con- centration of net incomes at the very top of the distribution has strongly increased in Germany.
