  abstract  = {In der Theorie bieten dezentrale Steuerungsans{\"a}tze im Produktionskontext einige Vorteile gegen{\"u}ber monolithischen Zentralsystemen, die s{\"a}mtliche Funktionen in einer oder wenigen Instanzen vereinen. Allerdings bedarf die praktischen Umsetzung der Anpassung des allgemeinen Konzepts der Dezentralit{\"a}t an die individuellen und spezifischen Anwendungsf{\"a}lle insbesondere hinsichtlich ihres sinnvollen Umfangs. Ein Anwendungsfall ist die Montage von variantenreichen Produkten. Der vorliegende Beitrag zeigt, wie mittels der geeigneten Kombination von zentralen und dezentralen Ans{\"a}tzen eine bessere Planbarkeit und Steigerung des Durchsatzes erreicht werden kann. Mit einer flexiblen Taktsteuerung der Arbeitsstationen und geeigneter Assistenz am Montagearbeitsplatz kann die bisherige werkstatt-orientierte Organisation zu einer serien{\"a}hnlichen Fertigung transformiert werden. Dies geschieht unter Einsatz einer mehrschichtigen Infrastruktur, die den Industrie 4.0-Paradigmen der dezentralen Informationsverarbeitung durch autonome vernetzte Systeme folgt.},

  abstract  = {A potential human footprint on Western Central African rainforests before the Common Era has become the focus of an ongoing controversy. Between 3,000 y ago and 2,000 y ago, regional pollen sequences indicate a replacement of mature rainforests by a forest-savannah mosaic including pioneer trees. Although some studies suggested an anthropogenic influence on this forest fragmentation, current interpretations based on pollen data attribute the "rainforest crisis" to climate change toward a drier, more seasonal climate. A rigorous test of this hypothesis, however, requires climate proxies independent of vegetation changes. Here we resolve this controversy through a continuous 10,500-y record of both vegetation and hydrological changes from Lake Barombi in Southwest Cameroon based on changes in carbon and hydrogen isotope compositions of plant waxes. delta C-13-inferred vegetation changes confirm a prominent and abrupt appearance of C-4 plants in the Lake Barombi catchment, at 2,600 calendar years before AD 1950 (cal y BP), followed by an equally sudden return to rainforest vegetation at 2,020 cal y BP. delta D values from the same plant wax compounds, however, show no simultaneous hydrological change. Based on the combination of these data with a comprehensive regional archaeological database we provide evidence that humans triggered the rainforest fragmentation 2,600 y ago. Our findings suggest that technological developments, including agricultural practices and iron metallurgy, possibly related to the large-scale Bantu expansion, significantly impacted the ecosystems before the Common Era.},

Hier lehrte die Literaturwissenschaftlerin an der Friedrich-Wilhelms-Universit{\"a}t (heute Humboldt-Universit{\"a}t) und am Berliner Abendgymnasium (heute Peter A. Silbermann-Schule). Bereits kurz nach der Macht{\"u}bernahme von Adolf Hitler hatte sich um das Ehepaar Harnack ein Kreis von Freunden gebildet, der gegen die Herrschaft der Nationalsozialisten opponierte. Dazu z{\"a}hlten auch Karl Behrens und Bodo Schl{\"o}singer, die beide Sch{\"u}ler Mildred Harnacks am Berliner Abendgymnasium waren. Mildred Harnack konnte mit Hilfe ihrer Kontakte zur amerikanischen Botschaft ihren Sch{\"u}lern im nationalsozialistischen Deutschland ansonsten nicht zug{\"a}ngliche Informationen besorgen. Aufgrund von Funkkontakten des Freundeskreises zur Sowjetunion wurde die Gruppe von den Nationalsozialisten Rote Kapelle genannt - „rot" bezog sich auf deren linke Haltung und mit „Kapelle" wurden Funker assoziiert, die wie Pianisten in einer Kapelle spielen. Der Berliner Oppositionszirkel umfasste bis zu seiner Zerschlagung durch die Nationalsozialisten etwa 150 Personen verschiedenster Berufsgruppen, unterschiedlicher parteipolitischer Einstellungen und Konfessionen. Die Gruppe verfertigte oppositionelle Flugbl{\"a}tter und lieferte Informationen an die amerikanische Botschaft sowie an die Sowjetunion. Mildred Harnack wurde - wie viele ihrer Mitstreiterinnen und Mitstreiter - nach ihrer Verhaftung vom Reichskriegsgericht zum Tode verurteilt und am 16. Februar 1943 in Pl{\"o}tzensee guillotiniert. In diesem Band stellen Studierende der Universit{\"a}t Potsdam sowie H{\"o}rerinnen und H{\"o}rer der Peter A.

We show that, similar to the effect of positive local weather shocks, the effect of a locally-relevant global crop price increase on household out-migration depends on the initial household wealth. Higher international producer prices relax the budget constraint of poor agricultural households and facilitate migration. The order of magnitude of a standardized price effect is approx. one third of the standardized effect of a local weather shock. Unlike positive weather shocks, which mostly facilitate internal rural-urban migration, positive income shocks through rising producer prices only increase migration to neighboring African countries, likely due to the simultaneous decrease in real income in nearby urban areas. Finally, we show that while higher producer prices induce conflict, conflict does not play a role for the household decision to send a member as a labor migrant.},

As expected, gentrification benefits rich homeowners, while poor renter households lose. Our counterfactual analysis mimicks the rent control policy. We find that this policy reduces welfare for rich and poor households and in fact, the percentage change in welfare is largest for the poorest households. We also study alternative affordable housing policies such as subsidies and re-zoning policies, which are better suited to address the adverse consequences of gentrification.},

For this purpose, we combine two datasets: administrative records on xenophobic crime against refugee shelters by the Federal Criminal Office and the IAB-BAMF-SOEP Survey of Refugees. We apply a regression discontinuity in time design to estimate the effect of interest. Our results indicate that hate crime has a substantial negative effect on several mental health indicators, including the Mental Component Summary score and the Patient Health Questionnaire-4 score. The effects are stronger for refugees with closer geographic proximity to the focal hate crime and refugees with low country-specific human capital. While the estimated effect is only transitory, we argue that negative mental health shocks during the critical period after arrival have important long-term consequences.

We study how persistent telework may change energy and transport consumption and costs in Germany to assess the distributional and environmental implications when working from home will stick. Based on data from the German Microcensus and available classifications of working-from-home feasibility for different occupations, we calculate the change in energy consumption and travel to work when 15\% of employees work full time from home. Our findings suggest that telework translates into an annual increase in heating energy expenditure of 110 euros per worker and a decrease in transport expenditure of 840 euros per worker. All income groups would gain from telework but high-income workers gain twice as much as low-income workers. The value of time saving is between 1.3 and 6 times greater than the savings from reduced travel costs and almost 9 times higher for high-income workers than low-income workers. The direct effects on CO₂ emissions due to reduced car commuting amount to 4.5 millions tons of CO₂, representing around 3 percent of carbon emissions in the transport sector.},

The standard maximum likelihood estimator is consistent under asymptotics where all panel dimensions grow at a constant rate, but it has an asymptotic bias in its limiting distribution, invalidating inference even in situations where the bias appears to be small. Thus, we propose two different bias-corrected estimators. Monte Carlo simulations confirm their desirable statistical properties. We apply these estimators in a reassessment of the most commonly studied determinants of the extensive margin of trade.

As long as there is free access to information and technology, growth is sustainable and the allocation of research efforts among alternative technologies is socially optimal. While there still is a need to address externalities from monopolistic research markets, no environmental policy is necessary. These results suggest that environmental externalities may originate in restricted access to information and technology, demonstrating that (i) information has a similar effect as an environmental tax and (ii) knowledge and technology transfers have an impact comparable to that of subsidies for research in green technology.},

Using a German firm-level dataset of 700,000 observations between 2003 and 2017, we analyze this largely uncovered phenomenon among professional services, the 4th largest sector in the EU15 business economy, which provide important intermediate services for the rest of the economy. We show that changes in the value chain explain about half of the decline and the increase in part-time employment is a further minor part of the decline. In contrast to expectations, the entry of micro and small firms, despite their lower productivity levels, is not responsible for the decline. We also cannot confirm the conjecture that weakening competition allows unproductive firms to remain in the market.},

Considering that, this paper analyzes the impact of offering an ask avoidance option on charitable giving. In a proposed utility framework, the avoidance option decreases the social pressure to donate. At the same time, it induces feelings of gratitude toward the fundraiser, which may lead to a reciprocal increase in donations. The results of a lab experiment designed to disentangle the two channels show no negative impact of the option to avoid repeated asking on donations. Instead, the full model indicates a positive impact of the reciprocity channel. This finding suggests that it might be beneficial for charities to introduce an ask avoidance option during high-frequency fundraising campaigns.},

  abstract  = {Subsidizing the geographical mobility of unemployed workers may improve welfare by relaxing their financial constraints and allowing them to find jobs in more prosperous regions. We exploit regional variation in the promotion of mobility programs along administrative borders of German employment agency districts to investigate the causal effect of offering such financial incentives on the job search behavior and labor market integration of unemployed workers. We show that promoting mobility - as intended - causes job seekers to increase their search radius, apply for and accept distant jobs. At the same time, local job search is reduced with adverse consequences for reemployment and earnings. These unintended negative effects are provoked by spatial search frictions. Overall, the unconditional provision of mobility programs harms the welfare of unemployed job seekers.},

  abstract  = {This paper aims to contribute a different approach to transitional justice, one in which political decisions are rocketed to the forefront of the research. Theory asserts that, after a transition to democracy, it is the constituency who defines the direction a country will take. Therefore, pleasing them should be at the fore of the responses taken by those in power. However, reality distances itself from theory. History provides us with many examples of the contrary, which indicates that the politicization of transitional justice is an ever-present event. The first section will outline current definitions and obstacles faced by transitional justice, focusing on the implicit ties between them and the aforementioned politicization. An original categorization of Transitional Justice as a method of analysis will also be introduced, which I denominate Political Opportunism. The case of Argentina, a country that is usually described as a model to export but that after 35 years is still dealing with the consequences brought by the contradictions of using several methods of justice, will then be reinterpreted through this perspective. At the end of the paper, the inevitable question will be posed: can this new angle be exported and implemented in every transition?},

  abstract  = {In light of climate change mitigation efforts, revenues from climate policies are growing, with no consensus yet on how they should be used. Potential efficiency gains from reducing distortionary taxes and the distributional implications of different revenue recycling schemes are currently debated. To account for households heterogeneity and dynamic trade-offs, we study the macroeconomic and welfare performance of different revenue recycling schemes using an Environmental Two-Agent New-Keynesian model, calibrated on the German economy. We find that, in the long run, welfare gains are higher when revenues are used to reduce distortionary taxes on capital, but this comes at the cost of higher inequality: while all households prefer labor income tax reductions to lump-sum transfers, only financially unconstrained households are better off when reducing taxes on capital income. Interestingly, we find that over the transition period relevant to meet short-medium run climate targets, labor income tax cuts are the most efficient and equitable instrument.},
