    Recent Methodological Advances in Panel Data Collection, Analysis, and Application: Editorial

    Panel studies have become an indispensable part of today's research world especially when addressing causal questions and tracking changes over time. Three conditions are essential for effective panel data analysis: 1) having a sufficiently long time series with a substantial number of observations, 2) ensuring measurement consistency over time, and 3) using a meaningful model for selecting elements ...

    Estimating Mode Choice Inertia and Price Elasticities after a Price Intervention – Evidence from Three Months of almost Fare-free Public Transport in Germany

    This study analyses the behavioural response of travellers on a temporal reduction of public transport prices in Germany through the so-called 9 Euro Ticket during summer 2022. The focus is on the inertia effect, e.g. the resistance to change behaviour, on people's travel mode decisions for commuter trips. We estimate mixed logit models for nearly 7,000 commuter trips, based on GPS-tracking data collected ...

    Competition and Moral Behavior: A Meta-Analysis of Forty-Five Crowd-Sourced Experimental Designs

    Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental ...

    Socioeconomic Differences in SARS-CoV-2 Infection and Vaccination in Germany: A Seroepidemiological Study After One Year of COVID-19 Vaccination Campaign

    Objective: To evaluate the socioeconomic patterns of SARS-CoV-2 antigen contacts through infection, vaccination or both (“hybrid immunity”) after 1 year of vaccination campaign.Methods: Data were derived from the German seroepidemiological Corona Monitoring Nationwide study (RKI-SOEP-2; n = 10,448; November 2021–February 2022). Combining serological and self-report data, we estimated adjusted prevalence ...

    Uncertainties in Estimating Production Costs of Future Nuclear Technologies: A Model-based Analysis of Small Modular Reactors

    Predicting future costs of technologies not yet developed is a complex exercise that includes many uncertain parameters and functional forms. In that context, small modular reactor (SMR) concepts that are in a rather early development stage claim to have cost advantages through learning effects, standardized design, modularization, co-siting economies, and other factors, such as better time-to-market ...

    Putting MARS into Space: Non Linearities and Spatial Effects in Hedonic Models

    Multivariate Adaptive Regression Spline (MARS) is a simple and powerful non-parametric machine learning algorithm that automatizes the selection of non-linear terms in regression models. In this study, we propose using MARS in a spatial regression framework to account for potential non-linearities and spatial effects in spatial regression models. Using a relatively large data set of 17,000 dwellings ...

    Combining GPS Tracking and Surveys for a Mode Choice Model: Processing Data from a Quasi-Natural Experiment in Germany

    This paper deals with the data generation process implemented for an analysis of the impact of the 9-Euro ticket on mode choice. We discuss the assumptions made and procedures used to process a raw dataset that is based on GPS traces of individuals’ movements and on survey data into the choice-set for a discrete choice model. Several steps of cleaning and merging are described in order to a) obtain ...
