Kant, das geltende Recht und die Einstellungen der Bürger zu Flüchtlingen und anderen Migranten

Welche Zuwanderer sollten nach Deutschland kommen dürfen? Auf Basis einer repräsentativen Umfrage zeigen wir, dass sich die Meinungen der Befragten mit dem geltenden Recht und seiner philosophischen Begründung durch Kant decken. (1) Sie plädieren trotz erwarteter Nachteile für eine Aufnahme von Flüchtlingen, solange legitime Fluchtgründe bestehen. (2) Zu regulären Migranten überwiegen Nützlichkeitsüberlegungen: ...

Klimaschutzpolitik: Wie kann ein Politikmix gestaltet werden?

Zum Schutz des Klimas ergreift die Politik in Deutschland und Europa eine Vielzahl an Maßnahmen. So wird der europäische Emissionshandel durch zahlreiche Maßnahmen zur Innovations- und Investitionsförderung ergänzt, aber auch durch Informationsbereitstellung und Regulierungsmaßnahmen zur Nutzung neuer Technologien. Dieser Politikmix wirft die Frage auf, welche Politikinstrumente benötigt werden und ...

Zur Bedeutung nationalsozialistischer Statistiken und Statistiker nach dem Krieg: Rolf Wagenführ und der United States Strategic Bombing Survey (USSBS)

After the war, NS-statistics were put to manifold uses. Indeed, the industrial census of 1936 served both as a benchmark for the restrictions on German production imposed by the allied powers and as an indispensable input for the introduction of the planned economy in East Germany. In addition the NS-statisticians involved were also considered indispensable for interpreting and implementing these statistics. ...

European Scenarios of CO2 Infrastructure Investment

Based on a review of the current state of the Carbon Capture, Transport and Storage (CCTS) technology, this paper analyzes the layout and costs of a potential CO2 infrastructure in Europe at the horizon of 2050. We apply the mixed-integer model CCTS-Mod to compute a CCTS infrastructure network for Europe, examining the effects of different CO2 price paths with different regional foci. Scenarios assuming ...

Renewable Energy Support, Negative Prices, and Real-Time Pricing

We analyze the welfare effects of two different renewable support schemes designed to achieve a given target for the share of fluctuating renewable electricity generation: a feed-in premium (FiP), which can induce negative wholesale prices, and a capacity premium (CP), which does not. For doing so we use a stylized economic model that differentiates between real-time and flat-rate pricing and is loosely ...

European Electricity Grid Infrastructure Expansion in a 2050 Context

This paper analyzes the development of the European electricity transmission network for different policy scenarios at the horizon 2050. We apply a bottom-up techno-economic electricity sector model to determine transformation scenarios of the European electricity sector. It has a very detailed spatial disaggregation that allows for a fine representation of domestic and international electricity flows ...

Coordinating Cross-Country Congestion Management: Evidence from Central Europe

We employ a detailed two-stage model to simulate the operation of the Central Eastern European electricity market and network. Implementing different cases of coordination in congestion management between national transmission system operators, numerical results show the beneficial impact of closer cooperation. Specific steps comprise the sharing of network and dispatch information, cross-border counter-trading, ...

The Role of Natural Gas in a Low-Carbon Europe: Infrastructure and Supply Security

In this paper, we analyse infrastructure needs of the European natural gas market in response to decarbonisation of the European energy system. To this end, we use numerical modelling and apply the Global Gas Model. We investigate three pathways of future natural gas consumption: i) a decreasing natural gas consumption, following the scenarios of the EU Energy Roadmap 2050; ii) a moderate increase ...

Introduction

FTR Allocations to Ease Transition to Nodal Pricing: An Application to the German Power System

A shift from zonal to nodal pricing improves the efficiency of system operation. However, resulting price changes also shift surplus across generation and loads at different locations. As individual actors can lose, they might oppose any reform. We explore how allocation of financial transmission rights can be used to mitigate the distributional impact. The fundamental effects with regard to reference ...

Drohende Altersarmut - neue Aufgaben für die Rentenversicherung?

The Impact of Extreme Weather Events on Education

This paper provides new evidence on the long- and medium-term impact of extreme weather events on education. Our focus is on Mongolia, where two extremely severe winters caused mass livestock mortality. We use household panel data with information on households' pre-shock location, combined with historic district-level livestock census data and climate data. Our econometric strategy exploits exogenous ...

The Impact of Stress on Tournament Entry

Individual willingness to enter competitive environments predicts career choices and labor market outcomes. Meanwhile, many people experience competitive contexts as stressful. We use two laboratory experiments to investigate whether factors related to stress can help explain individual differences in tournament entry. Experiment 1 studies whether stress responses (measured as salivary cortisol) to ...

Two Price Zones for the German Electricity Market: Market Implications and Distributional Effects

e discuss the implications of two price zones (i.e., one northern and one southern bidding area) on the German electricity market. In the northern zone, continuous increases in capacity with low variable costs cause large regional supply surpluses in the market dispatch, while in the southern zone conventional capacity decreases. As the spatial imbalance of supply and load is increasing, the current ...

Family Ownership: Does It Matter for Funding and Success of Corporate Innovations?

Using the Mannheim innovation panel, we investigate whether family firms have higher financial need and how this affects both innovation input and innovation outcomes such as firm or market novelties, or process innovation. Applying the CDM framework, we find that family firms are more likely to have a latent financial need for innovation, which means that they have innovation ideas which they have ...

Is the German Retail Gasoline Market Competitive? A Spatial-Temporal Analysis Using Quantile Regression

We explore whether noncompetitive pricing prevails in Germany’s retail gasoline market by examining the influence of the crude oil price on the retail gasoline price, focusing specifically on how this influence varies according to the brand and to the degree of competition in the vicinity of the station. Our analysis identifies several factors other than cost—including the absence of nearby competitors ...

Resource Curse Contagion in the Case of Yemen

This study analyses the economic developments in Yemen from the 1970s to today in the context of the resource curse hypothesis. After a brief survey of the resource curse literature, using empirical data, historical accounts, and political (economic) analyses, I confirm that post-reunification Yemen suffers from an intense oil curse. The curse is evidenced by low genuine savings rates, oil-dependency, ...

Wie wird der Migrationsstatus in wissenschaftlichen Befragungen erhoben?

In Einwanderungsgesellschaften wie der Deutschlands ist die Erhebung migrationsbezogener Merkmale in wissenschaftlichen Befragungen sowie der offiziellen Statistik relevant, u. a. um Ungleichheiten und Integrationsverläufe sichtbar zu machen. Wie wird der Migrationsstatus bzw. der Migrationshintergrund aktuell in wissenschaftlichen Erhebungen erfragt?

Psychische Gesundheit und Lebensqualität von Zuwanderern und deren Nachkommen im SOEP in den Jahren 1984-2016

Das Sozio-ökonomische Panel hält für die Erforschung der psychischen Gesundheit und Lebensqualität von Zuwanderern ein großes Analysepotenzial bereit. Der Beitrag beleuchtet sowohl die Güte der Stichprobenziehung, die Zusammensetzung und den Umfang von Personen mit Migrationshintergrund in dieser Datengrundlage, als auch die für das Thema psychische Gesundheit und Lebensqualität zur Verfügung stehenden ...

Testing for Identification in SVAR-Garch Models

Changes in residual volatility in vector autoregressive (VAR) models can be used for identifying structural shocks in a structural VAR analysis. Testable conditions are given for full identification for the case where the volatility changes can be modelled by a multivariate GARCH process. Formal statistical tests are presented for identification and their small sample properties are investigated via ...
