Data-driven innovators – An empirical analysis of data-driven SMEs and start-ups
(2024) Darold, Denilton Luiz; Ebersberger, Bernd
In today's fast-paced technological landscape, the adoption of Big Data Analytics (BDA) goes beyond incremental improvements in productivity and efficiency, enabling the creation of new products, services, and even business models, known as Data-Driven Innovations (DDI). As technology evolves rapidly, reshaping industries and our daily lives, businesses must adapt to survive and innovate to thrive. Entrepreneurs, in particular, have a vast horizon of possibilities to explore through data, opening avenues for new ventures. However, the literature in the field has pointed to a lack of empirical evidence on the actual realization of these possibilities, the so-called ‘deployment gap’. Also, regarding established firms, there is a recurrent call for longitudinal analysis to understand the dynamics of BDA adoption and firm performance.
Motivated by these challenges, this study employs a data-driven methodology that integrates data science techniques, like web scraping, natural language processing (NLP), and neural topic modeling (BERTopic), to provide large-scale empirical evidence on the realization of the DDI, focusing on understanding the firms behind them. The objectives range from identifying data-driven firms using website text to analyzing the determinants of adoption, firm performance dynamics, and emerging business models in startups.
The study starts by focusing on German knowledge-intensive SMEs and identifying factors influencing BDA adoption, following the Technology-Organization-Environment (TOE) Framework. The findings show that larger, younger firms with international ownership are more likely to adopt BDA technologies, and this adoption is positively associated with innovation indicators such as patents and trademarks. The second study, grounded on Resource-Based-View (RBV), extends the analysis by exploring the timing of DDI deployment and its impact on firm performance over time using panel data. The results show that early adoption confers performance gains, particularly in technology-intensive sectors, but these gains tend to decrease as the technology becomes more widespread.
The third study shifts the focus to the global start-up ecosystem, analyzing emerging data-driven business models (DDBMs) by examining the value propositions of start-ups across various sectors. Using neural topic modeling, the research identifies key trends and patterns in DDBMs, confirming the increasing emphasis on AI and data science as central themes. The study also tracks the evolution of these trends over time, identifying a shift towards more specialized technological areas within start-ups' value propositions.
The empirical findings contribute to the broader discussion on BDA technologies, innovation, and their influence on firm performance. They offer insights not only to researchers conducting qualitative and theoretical studies but also to practitioners and policymakers involved in technology adoption and entrepreneurship. Methodologically, this work contributes to innovation studies by applying advanced data science techniques to analyze large-scale, unstructured data. These methods introduce a novel approach to uncovering patterns and insights that traditional methods may overlook, thereby advancing the study of digital innovations.
Fundamental parity conditions in international finance
(2024) Mößler, Markus; Jung, Robert
This thesis investigates the persistent deviations from Covered Interest Rate Parity (CIP), a cornerstone arbitrage condition in international finance, which have increasingly surfaced since the Global Financial Crisis (GFC) of 2007–2008. Despite the CIP condition being fundamental to the valuation of foreign exchange instruments, significant and sustained violations have challenged its empirical validity and puzzled both academics and practitioners. This study provides a comprehensive theoretical and empirical analysis of the CIP condition and its deviations, focusing on the contemporaneous and dynamic relationships between interest and exchange rates, as well as the role of arbitrage bounds. Employing a cointegrated regression model, the thesis first analyzes the structure of arbitrage strategies implied by CIP. It then utilizes a cointegrated vector autoregressive (VAR) model to assess the persistence of deviations and the speed of adjustment toward CIP equilibrium. Furthermore, the role of arbitrage bounds, such as transaction costs, is examined as a potential explanation for post-GFC anomalies. A macro-level comparison across multiple currency pairs, maturities, and time periods complements the analysis, extending beyond the traditionally studied USD-centric frameworks.
The empirical findings reveal that while CIP held before the GFC, deviations became both large and persistent in the aftermath—particularly for the USD/EUR pair—with no sufficient justification from arbitrage bounds alone. The estimated arbitrage strategy weights and slower post-crisis adjustment dynamics underscore structural shifts in market functioning. These insights contribute to a deeper understanding of modern financial market frictions and open pathways for further research into evolving global financial architectures.

Grünendes Land der Futterwirtschaft
aus der Kriegsnot entstand vor 100 Jahren in Niederbayern die deutsche Grünlandbewegung
(2020) Grundler, Thomas
Als um 1890 in Frankfurt Dr. jur. Carl von Lang-Puchhof den aus Karlsruhe stammenden Dr. jur. August Sehmieder kennen lernte und mit ihm einen gemeinsamen Rennstall für Galopprennpferde gründete, war nicht zu ahnen, welch große Bedeutung dies für die spätere Grünlandforschung und Futterpflanzenzüchtung Deutschlands haben sollte.
