Zehn Jahre nach dem großen Knall: wie ist es um die Stabilität der internationalen Immobilienmärkte bestellt?

Zehn Jahre nach der weltweiten Finanz- und Wirtschaftskrise, die ihren Ursprung auf dem US-amerikanischen Immobilienmarkt hatte, steigen angesichts weltweit zunehmender Preise für Wohneigentum die Sorgen vor neuen Immobilienpreisblasen. Dieser Beitrag zeigt auf Basis von OECD-Daten für 20 Länder, dass die Sorge nicht unberechtigt ist: In acht Ländern deutet die Immobilienpreisentwicklung auf ein spekulatives ...

Analyzing Scenarios for the Integration of Renewable Energy Sources in the Mexican Energy System: An Application of the Global Energy System Model (GENeSYS-MOD)

This paper uses numerical techno-economic modelling to analyse the effect of current national renewable targets and climate goals on the cost and structural composition of the Mexican energy system. For this, we construct a scenario base analysis to compare current policies with two alternative states of the world—one without climate policies and one attaining full decarbonization. Furthermore, an ...

The Effects of Pricing Waste Generation: A Synthetic Control Approach

To internalize pollution externalities into household waste generation, Unit Pricing Systems (UPS) have been adopted worldwide. This paper evaluates the causal effects of a UPS on the disposal of municipal solid waste in Trento, Italy. Using a unique panel dataset of monthly waste generation in Italian municipalities, we employ the synthetic control method, which allows us to account for possible time-varying ...

Deutschland: ein Land der Mieter? Die Rolle von Erwartungen über zukünftige Immobilienpreisentwicklungen

Mehr als die Hälfte aller Haushalte in Deutschland wohnen zur Miete – ein im internationalen Vergleich sehr hoher Wert. Bisherige Studien haben vor allen Dingen den regulatorischen Rahmen des Immobilienmarkts hervorgehoben, der Mietwohnungen in Deutschland systematisch begünstigt. Allerdings gibt es keine Studien, die diese Erklärungen empirisch eindeutig untermauern können: einige Arbeiten betonen ...

Notes about Comparing Long-Term Care Expenditures across Countries: Comment on "Financing Long-Term Care: Lessons from Japan"

The comparison of long-term care (LTC) expenditures is a difficult task. National LTC systems differ widely in terms of eligibility criteria, level of benefits, institutional variety and regional heterogeneity. In this commentary I will first give some general remarks on cross country comparisons. Then I discuss the role of the informal sector which is the most important pillar of all LTC systems. ...

Exit Expectations and Debt Crises in Currency Unions

We study a sovereign debt crisis in a small member state of a currency union. If the country exits the currency union, it may redenominate its liabilities and reduce the real value of debt through depreciation and inflation. We analyze formally how the anticipation of this possibility, “exit expectations”, impact the dynamics of the sovereign debt crisis. First, we show that public debt accumulates ...

Poor Glucose Regulation is Associated with Declines in Well-Being among Older Men, but not Women

Glucose regulation is a key aspect of healthy aging and has been linked to brainfunctioning and cognition. Here, we examined the role of glucose regulation for withinpersonlongitudinal trajectories of well-being. We applied growth models to data fromthe Berlin Aging Study II (N = 1,437), using insulin resistance as an index of glucoregulatorycapacity. We found that poor glucose regulation (higher insulin ...

Comparing Administrative and Survey Data: Is Information on Education from Administrative Records of the German Institute for Employment Research Consistent with Survey Self-Reports?

In research on stratification and inequality, administrative data are popular for their wide coverage and assumed high quality. Yet, the quality of the data depends crucially on the aim of data collection. In this paper, we investigate the quality of information on education in administrative data from social security records provided by the German Federal Institute for Employment Research where education ...

Can Happiness Apps Generate Nationally Representative Datasets? - a Case Study Collecting Data on People’s Happiness Using the German Socio-Economic Panel

In the last few years, apps have become an important tool to collect data. Especially in the case of data on people’s happiness, two projects have received substantial attention from both the media and the scientific world: “Track your happiness” from Killingsworth and Gilbert (Science, 330, 932-932, 2010), and “Mappiness,” from MacKerron (2012). Both happiness apps used the experience sampling method ...

Closing Routes to Retirement for Women: How Do They Respond?

We study the employment effects of a large increase in the early retirement age (ERA) of women. Raising the ERA has the potential to extend contribution periods and to reduce the number of pensioners at the same time. However, workers may not be able to work longer or may choose other social support programs as exit routes from employment. Results suggest that the reform increases employment, unemployment ...

Parental Leave Policies and Socio-Economic Gaps in Child Development: Evidence from a Substantial Benefit Reform Using Administrative Data

This paper examines the effects of substantial changes in paid parental leave on child development and socio-economic development gaps. We analyse a German reform that replaced a means-tested with an earnings-related benefit scheme. Higher-income households benefited relatively more from the reform than low-income households. The reform expanded paid leave in the first year, while it removed paid leave ...

The Fayherriot Command for Estimating Small-Area Indicators

We introduce a command, fayherriot, that implements the Fay–Herriot model (Fay and Herriot, 1979, Journal of the American Statistical Association 74: 269–277), which is a small-area estimation technique (Rao and Molina, 2015, Small Area Estimation), in Stata. The Fay–Herriot model improves the precision of area-level direct estimates using area-level covariates. It belongs to the class of linear mixed ...

Drivers of Renewable Technology Adoption in the Household Sector

Using data from the German Socio-Economic Panel, we undertake a simultaneous assessment of the importance of factors that are individually found to be significant for the adoption of renewable energy systems by households but are not yet tested jointly. These are sociodemographic and housing characteristics, environmental concern, personality traits, and economic factors; i.e. the expected costs of ...

Analyzing Climate and Energy Policy Integration: The Case of the Mexican Energy Transition

One of the main challenges faced by climate policy makers today is to design and implement policies capable of transferring climate policy goals into sectoral actions towards transformational pathways. Hence, climate policies need to be of cross-cutting character, lead to coherence with sectoral goals and reconcile diverging sectoral interests. Against this background, Mexico has undertaken significant ...

Anticipating Global Energy, Climate and Policy in 2055: Constructing Qualitative and Quantitative Narratives

This study presents a set of novel and multidisciplinary scenarios (‘narratives’) that provide insight into four distinct and diverging yet plausible worlds. They combine qualitative and quantitative elements in order to reflect the interlinked and complex nature of energy and climate. We use the STEMPLE+ framework to include social, technological, economic, military (security), political, environmental, ...

Pathways for Germany’s Low-Carbon Energy Transformation Towards 2050

Like many other countries, Germany has defined goals to reduce its CO2-emissions following the Paris Agreement of the 21st Conference of the Parties (COP). The first successes in decarbonizing the electricity sector were already achieved under the German Energiewende. However, further steps in this direction, also concerning the heat and transport sectors, have stalled. This paper describes three possible ...

The Effect of Peer Observation on Consumption Choices: Evidence from a Lab-In-Field Experiment

We investigate the impact of peer observation on consumption decisions using a lab-in-field experiment. Respondents make consumption decisions either alone or under peer observation. We find evidence for peer effects. We are able to study these further by looking into the mechanism and performing detailed heterogeneity analysis. Concerning the mechanisms, we find evidence for an information channel. ...

The Effects of Conflict on Fertility: Evidence from the Genocide in Rwanda

Our study analyzes the fertility effects of the 1994 genocide in Rwanda. We study the effects of violence on both the duration time to the first birth in the early post-genocide period and on the total number of post-genocide births per woman up to 15 years following the conflict. We use individual-level data from Demographic and Health Surveys, estimating survival and count data models. This article ...
