The Economics of the EU ETS Market Stability Reserve: Introduction

Longitudinal Wealth Data and Multiple Imputation: An Evaluation Study

Statistical analysis in surveys is generally facing missing data. In longitudinal studies for some missing values there might be past or future data points available. The question arises how to successfully transform this advantage into improvedimputation strategies. In a simulation study the authors compare six combinations of cross-sectional and longitudinal imputation strategies for German wealth ...

Think National, Forecast Local: A Case Study of 71 German Urban Housing Markets

In this article, we examine whether the local indicators are able to predict the city-level housing prices and rents better than national indicators. For this purpose, we assess the forecasting ability of 126 indicators and 21 types of forecast combinations using a sample of 71 large German cities. There are several predictors that are especially useful, namely price-to-rent ratios, national-level ...

Offset Credits in the EU ETS: A Quantile Estimation of Firm-Level Transaction Costs

International carbon offset certificates were cheaper than European Union Allowances, although they were substitutes within the EU Emissions Trading System (EU ETS). Thus, firms had a strong incentive to use offset certificates. However, a considerable number of firms did not exhaust their offset quota and, by doing so, seemingly forwent profits. While most literature on emissions trading evaluates ...

Empirics on the Long-Run Effects of Building Energy Codes in the Housing Market

We study the effectiveness of building energy codes, taking a long-run perspective. The focus is on regulation’s impact on energy demand in both high- and low-quality residences, in other words, the diffusion and the entry of “green” buildings in the housing market. We develop a measure for regulation intensity and apply this to a panel-error-correction regression model for energy requirements of a ...

Genetic Variants Linked to Education Predict Longevity

Educational attainment is associated with many health outcomes, including longevity. It is also known to be substantially heritable. Here, we used data from three large genetic epidemiology cohort studies (Generation Scotland, n = ∼17,000; UK Biobank, n = ∼115,000; and the Estonian Biobank, n = ∼6,000) to test whether education-linked genetic variants can predict lifespan length. We did so by using ...

The Informed Consent to Record Linkage in Panel Studies: Optimal Starting Wave, Consent Refusals, and Subsequent Panel Attrition

Social scientists increasingly link survey data with administrative records. However, data protection legislation often requires respondents’ informed consent prior to record linkage. This has confronted research with nontrivial refusal rates in combination with selectivity of the consent decision. In longitudinal surveys, linkage requests may also increase attrition rates in subsequent waves, as many ...

Genome-Wide Analysis Identifies 12 Loci Influencing Human Reproductive Behavior

The genetic architecture of human reproductive behavior—age at first birth (AFB) and number of children ever born (NEB)—has a strong relationship with fitness, human development, infertility and risk of neuropsychiatric disorders. However, very few genetic loci have been identified, and the underlying mechanisms of AFB and NEB are poorly understood. We report a large genome-wide association study of ...

Ehegattenbesteuerung aus wirtschafts- und sozialpolitischer Perspektive: mehr Individualbesteuerung

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 ...
