Fast-and-frugal trees (FFTs) are simple algorithms that facilitate efficient and accurate decisions based on limited information. But despite their successful use in many applied domains, there is no widely available toolbox that allows anyone to easily create, visualize, and evaluate FFTs. We fill this gap by introducing the R package FFTrees. In this paper, we explain how FFTs work, introduce a new ...

This paper analyses whether exporting firms are less CO2 emission-intensive than non-exporting competitors. It exploits a novel and unique dataset for Germany, a major exporting country. Due to the direct link between CO2 emissions and fuels consumed, we argue that it is necessary to employ a production function framework to consistently analyse CO2 emission intensity. We show that such an approach ...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007–2014 period. We find an average pass-through rate of around 60%. This significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have greater market power because customers are less willing to switch, is only 50%, it increases to 70% in the competitive ...

Informed decision making in medicine, defined as basing one’s decision on the best current medical evidence, requires both informed physicians and informed patients. In cancer screening, however, studies document that these prerequisites are not yet met. Many physicians do not know or understand the medical evidence behind screening tests, do not adequately counsel (asymptomatic) people on screening, ...

It is widely acknowledged that data sharing has great potential for scientific progress. However, so far making data available has little impact on a researcher’s reputation. Thus, data sharing can be conceptualized as a social dilemma. In the presented study we investigated the influence of the researcher's personality within the social dilemma of data sharing. The theoretical background was the appropriateness ...

Both lifespan psychology and life course sociology highlight that contextual factors influence individual functioning and development. In the current study, we operationalize context as county-level care services in inpatient and outpatient facilities(e.g., number of care facilities, privacy in facilities) and investigate how the care context shapes well-being in the last years of life. To do so, we ...

Open-ended questions have routinely been included in large-scale survey and panel studies, yet there is some perplexity about how to actually incorporate the answers to such questions into quantitative social science research. Tools developed recently in the domain of natural language processing offer a wide range of options for the automated analysis of such textual data, but their implementation ...

This paper provides a literature review on wind power and externalities from multiple perspectives. Specifically, the economic rationale behind world-wide wind power deployment is to mitigate negative externalities of conventional electricity technologies, notably emissions from fossil fuels. However, wind power entails externalities itself. Wind turbines can lower quality of human life through noise ...

The purpose of this article is twofold. First, we review model-based analyses that explore the role of power storage in energy systems with high shares of variable renewables. Second, we introduce a new model that is specifically designed for exploring long-term storage requirements. The literature survey focuses on recent contributions in the peer-reviewed energy economics and engineering literature. ...

We use the model DIETER, introduced in a companion paper, to analyze the role of power storage in systems with high shares of variable renewable energy sources. The model captures multiple system values of power storage related to arbitrage, capacity, and reserve provision. We apply the model to a greenfield setting that is loosely calibrated to the German power system, but may be considered as a more ...

Based on large representative German household survey data, we compare incomes of the self-employed with those of paid employees. We find that the entrepreneurial income gap is largest for those holding a tertiary degree, but in two directions: positive for employers (self-employed with further employees) and negative for solo entrepreneurs. Entrepreneurs holding a tertiary degree also face the greatest ...

Redistributive policies can provide an insurance against future negative economic shocks. This, in turn, implies that an individual's demand for redistribution is expected to increase with her risk aversion. To test this prediction, we elicit risk aversion and demand for redistribution through a well-established set of measures in a representative sample of the Swedish population. We document a statistically ...

Unemployment continues to be one of the major challenges in industrialized societies. Aside from its economic and societal repercussions, questions concerning the subjective experience of unemployment have recently attracted increasing attention. Although existing studies have documented the detrimental effects of unemployment for cognitive (life satisfaction) and affective well-being, studies directly ...

Economists consider personality traits to be stable, particularly throughout adulthood. However, evidence from psychological studies suggests that the stability assumption may not always be valid, as personality traits can respond to certain life events. Our paper analyzes whether and to what extent personality traits are malleable over a time span of eight years for a sample of working individuals. ...

This paper proposes a rating methodology that is based on a non-linear classification method, a support vector machine, and a non-parametric isotonic regression for mapping rating scores into probabilities of default. We also propose a four data set model validation and training procedure that is more appropriate for credit rating data commonly characterised with cyclicality and panel features. Tests ...

We analyse the effects of playing music, or doing sports on education and health outcomes of adolescents. After identifying adolescents who play music, do sports, or both, in the German Socio-Economic Panel, we use matching procedures to estimate causal effects. We find that playing music instead of doing sports fosters educational outcomes by about 0.1 standard deviations. Effects are stronger for ...

This article analyses the determinants of Chinese foreign direct investment (FDI) activities in the European Union (EU). Evidence is based on panel Poisson models drawing on two investment monitors at the individual project level. Greenfield investments (GI) and mergers and acquisitions (M&A) are distinguished. The findings indicate that market size and bilateral trade are the main factors for Chinese ...

(G)ARCH-type models are frequently used for the dynamic modelling and forecasting of risk attached to speculative asset returns. While the symmetric and conditionally Gaussian GARCH model has been generalized in a manifold of directions, model innovations are mostly presumed to stem from an underlying IID distribution. For a cross section of 18 stock market indices, we notice that (threshold) (T)GARCH-implied ...
