The IAB/ZEW Start-Up Panel is a longitudinal and representative survey established in 2008, designed to focus on founders and their businesses during the very early stages of the firm life cycle. Data on newly founded companies, their founders, business activities, and innovation and market strategies is scarce, posing challenges for both research and evidence-based policymaking. The IAB/ZEW Start-Up Panel’s objective is to provide reliable research data on new businesses in Germany for the research community. This paper outlines the panel’s… [read more]

While many digital technologies provide opportunities for creating business models that impact sustainability, some technologies, especially blockchain applications, are often criticized for harming the environment, e.g. due to high energy demand. In our study, we present a novel approach to identifying sustainability-focused blockchain companies and relate their level of engagement to location factors and entrepreneurial ecosystem embeddedness. For this, we use a large-scale web scraping approach to analyze the textual content and hyperlink… [read more]

The availability of social media data is growing and represents a new data source for economic research. This paper presents a detailed study on the use of data from a career-oriented social networking platform. The employment data are exported from user profiles and linked to the Mannheim Enterprise Panel (MUP). The linked employer–employee (LEE) data consist of 14 million employments for 1.5 million employers and describes around 9 million employee flows. Plausibility checks confirm that career-oriented social networking data contain valuable… [read more]

We argue that greater founders’ openness, extraversion, and entrepreneurial orientation enhance seeking of start-up subsidies, while greater founders’ agreeableness, conscientiousness, and neuroticism inhibit it. Additionally, we argue that entrepreneurial… [read more]

In recent years, transportation network companies (TNCs) have grown rapidly. However, with the high intensity of competition caused by multi-homing and low switching costs, providers like Uber and Lyft have yet to achieve profitability. Following the winner-takes-all theory, providers fight for market dominance with price wars and incentives, expecting to achieve profitability once they gain market power. However, despite extensive research on why customers use TNCs instead of other modes, there is limited research on customer choice between… [read more]

Increasing the participation of women in top-level corporate boards is high on the agenda of policy-makers. Yet, we know little about director appointment dynamics and the drivers and impediments of women appointments. This study builds on organizational and group-level behavior theories and empirically investigates how ex-ante board structures and gender-specific board dynamics impact the representation of women on corporate boards. We study boards of listed firms in Europe between 2002 and 2019 and find a declining appointment probability for… [read more]
