Season Ticket Adoption in Public Transport: The Role of Reliability and Behavioural Inertia

This paper analyses the determinants of peoples’ decision to purchase public transport season tickets. Based on the Deutschlandticket, it focuses on identifying primary customer groups, the role of public transport irregularities such as delays and cancellations, and behavioural inertia of repetitive purchase decisions. It builds on a panel dataset covering survey answers and GPS tracking data from ...

The Value of Care: Brokering Work Conditions and Wages within a Transnational Care System

This article explains how the triadic brokering system in the European Union affects the conditions of work and pay of mobile care workers. Using original survey data gathered from Polish care workers in Germany, the authors found that workers earn less money the more hours they work. Based on qualitative interviews with care workers and representatives of labor market intermediaries, they argue that ...

Heteroskedastic Structural Vector Autoregressions Identified via Long-Run Restrictions

A central assumption for identifying structural shocks in vector autoregressive (VAR) models via heteroskedasticity is the time-invariance of the impact effects of the shocks. It is shown how that assumption can be tested when long-run restrictions based on the cointegration structure of the variables are available for identifying structural shocks. The importance of performing such tests is illustrated ...

Public Communication and Collusion: New Screening Tools for Competition Authorities

Competition authorities increasingly rely on economic screening tools to identify markets where firms deviate from competitive norms. Traditional screening methods assume that collusion occurs through secret agreements. However, recent research highlights that firms can use public announcements to coordinate decisions, thereby reducing competition while avoiding detection.We propose a novel approach ...

Aligning Competition Policy and Industrial Policy in the EU

Trade conflicts, geopolitical tensions, digital disruption, and the climate crisis pose major challenges for the European Union (EU) and its Member States. As called for in the Draghi Report, industrial policy measures can increase competitiveness, strengthen resilience, and facilitate the twin transformation. This article explores ways in which competition policy can be realigned to better accommodate ...

Innovation Dynamics and Technological Maturity in the Fusion Sector: An Assessment of Fusion Projects

Nuclear fusion is envisioned for near-term energy generation deployment, with projected timelines for commercial deployment of fusion expected for the 2030s. Previous research has been limited to either economic or technological maturity assessments of the sector. To address this gap, we design a novel framework that evaluates fusion projects across the most common reactor types and derives the trajectories ...

Unintended Consequences of COVID-19 Public Health and Social Measures in Camps and Camp-Like Settings: A Systematic Review and Conceptual Analysis

Objectives: This study examines unintended consequences (UIC) of public health and social measures (PHSM) in camps and camp-like settings and assesses the pathways through which these UIC arise. Methods: We conducted a systematic review and conceptual analysis of UIC from PHSM aimed at preventing SARS-CoV-2 spread in these settings. PHSM were classified using the WHO taxonomy and the CONSEQUENT framework ...

Sector Coupling Reimagined: Synthesizing Fragmented Perspectives Into a Unified Framework

Sector coupling (SC), the integration of energy vectors and end-use sectors, is increasingly central to the net-zero transition but remains conceptually fragmented. This fragmentation causes modeling inconsistencies, hinders cross-study comparison, and undermines energy policy coordination. We address this gap through a structured mapping of existing definitions, categorizing them along three dimensions, ...

Multi-Threshold Time Series Analysis Enables Characterization of Variable Renewable Energy Droughts in Europe

Variable renewable energy droughts, so called Dunkelflaute events, emerge as a challenge for climateneutral energy systems based on variable renewables. Here we characterize European drought events for on- and offshore wind power, solar photovoltaics, and renewable technology portfolios, using 38 historic weather years and an advanced identification method. Their characteristics heavily depend on the ...

Within-Nation Variation in War Exposure and Psychological and Physical Adjustment
