Authenticity or strategy? How universities communicate the Sustainable Development Goals
Universities play a crucial role in advancing the United Nations Sustainable Development Goals (SDGs) through education, research, and public engagement. This study examines how universities communicate their contributions to the SDGs, analyzing over 100,000 press releases and more than 2 million publications from 76 German institutions across two decades. Our findings reveal significant variation in SDG-related communication across institutions,…
Spinning stories
The successful transition toward renewable energies requires public support in areas where their expansion may cause adverse effects. In this context, narratives are crucial as they shape people's perceptions. This article examines the relationship between onshore wind power and related narratives in regions across Germany. We run a series of spatial regression models on regional newspaper data, and our findings suggest that wind-related topics a…
Feeling the heartbeat of regions
Timely and spatially detailed indicators of regional economic activity are limited. This article introduces the Regional Economic News Sentiments (REGENS) index, a high-frequency measure based on geocoded news headlines from 300+ German-language outlets since 2019. REGENS captures local economic sentiment, aligns with national indicators, and significantly leads regional unemployment by up to 4 months. While its link to GDP growth is weaker, it c…
Smart Specialisation or smart following? A study of policy mimicry in priority domain selection
This paper explores the phenomenon of mimicry in the selection of economic domains for Smart Specialisation Strategies (S3) and discusses the regional policy implications of strategic mimicry. By analysing S3 documents from European regions, we identify and distinguish between two general types of mimicry: ‘follow the peers’ and ‘follow the role models’, against the more desirable ‘follow the indicators’ priority selection strategy. Our findings …
How regions diversify into new jobs
This paper adds a multidimensional perspective to the study of related diversification. We examine how regions diversify into new jobs – defined as unique industry-occupation combinations – asking whether they do so from related industries or related occupations. We use linked employer-employee data for all labour market regions in Norway, covering the time period 2009–2014. Diversification into new jobs is more likely in the presence of related …
The role of geographic distance and technological complexity in U.S. interregional co-patenting over almost two centuries
This paper examines how geographical proximity affected interregional co-patenting links in various technologies in the USA from 1836 to 2010. We classify technologies by their complexity and test whether it moderates the impact of distance on collaboration. Contrary to the ‘death of distance’ hypothesis, distance still matters for knowledge creation and exchange. Moreover, we show that the role of complexity has changed over time. In the 19th ce…
Boosting, sorting and complexity—urban scaling of innovation around the world
It is widely understood that innovations tend to be concentrated in cities, which is evidenced by innovative output increasing disproportionately with city size. Yet, given the heterogeneity of countries and technologies, few studies explore the relationship between population and innovation numbers. For instance, in the USA, innovative output scaling is substantial and is particularly pronounced for complex technologies. Whether this is a univer…
The Spatial Patterns of Student Mobility Before, During and After the Bologna Process in Germany
The paper contributes to the literature investigating students’ spatial mobility. By focusing on German higher education students with a novel dataset providing data from 1999 to 2015, we evaluate the impact of the change from a one‐tiered to the two‐tiered study structure of bachelor and master degrees (Bologna reform) on their inter‐regional mobility and its underlying drivers. Our analysis confirms the system change to slightly alter inter‐reg…
Saved by the news? Covid-19 in German news and its relationship with regional mobility behaviour
There are substantial differences across regions regarding COVID-19 infections and deaths, which are partly explained by differences in practicing social distancing. In this paper we argue that the portrayal of COVID-19 in regional media might be an important factor in explaining regional differences in social distancing. By using mobility as a proxy, and analysing data on regional news coverage in Germany, we investigate empirically whether the …
The geography of innovation and technology news - An empirical study of the German news media
Variations in the frequency and tone of news media are the focus of a growing literature. However, to date, empirical investigations have primarily confirmed the existence of such differences at the country level. This paper extends those insights to the subnational level. We provide theoretical arguments and empirical support for systematic regional variations in the frequency and sentiments of news related to innovation and new technologies. Th…
Still in the shadow of the wall? The case of the Berlin biotechnology cluster
The evolution of knowledge networks has recently received a lot of attention from researchers. Empirical studies have shown that different types of proximities and network structural properties play a decisive role in tie formation. The present paper contributes to this literature by arguing that while these are crucial, they do not capture the full range of localities' influence on the evolution of knowledge networks. We support our argument wit…
Searching through the Haystack
This article examines which economic domains regional policy makers aim to develop in regional innovation strategies, focusing in particular on the complexity of those economic domains and their relatedness to other economic domains in the region. We build on the economic geography literature that advises policy makers to target related and complex economic domains, and assess the extent to which regions actually do this. The article draws on dat…
New(s) data for entrepreneurship research? An innovative approach to use Big Data on media coverage
Explaining the dynamics of relatedness
Relatedness has become a key concept for studying the diversification of firms, regions and countries. However, studies tend to treat relatedness as being time-invariant or, alternatively, consider its evolution as exogenously given. This study argues that relatedness is inherently dynamic and endogenous to technological and economic developments. Using patent data, we test the extent to which relatedness between technologies developed along co-l…
Institutional change and network evolution
Institutional change and network evolution: explorative and exploitative tie formations of co-inventors during the dot-com bubble in the Research Triangle region. Regional Studies. This paper investigates how institutions impact tie formation, arguing that institutions can direct firm strategies towards exploration or towards exploitation. It translates these strategies into tie formations: explorative tie formation produces structural holes as a…
Analyzing demand-side efficiency in global health
This article investigates demand-side efficiency in global health-or the efficiency with which health system users convert public health resources into health outcomes. We introduce and explain the concept of demand-side efficiency as well as quantitative methods to empirically estimate it. Using a robust nonparametric form of technical efficiency analysis, we estimate demand side efficiency and its social determinants. We pilot these methods loo…
Factors Explaining the Spatial Agglomeration of the Creative Class
The paper contributes to the on-going debate about the relative importance of economic and amenity-related location factors for attracting talent or members of the creative class. While Florida highlights the role of amenities, openness and tolerance, others instead emphasize the role of regional productions systems, local labour markets and externalities. The paper sheds light on this issue by analysing the changes in the spatial distribution of…
The Co-evolution of Proximities – A Network Level Study
Broekel T. The co-evolution of proximities – a network level study, Regional Studies. Little is known about how network structures and proximity relations between linked actors evolve over time. This paper argues that a number of networks’ internal proximity structures are interrelated, which may give rise to specific types of co-evolution dynamics. An empirical investigation tests these arguments using information on the evolution of 280 network…
Do Cooperative Research and Development (R&D) Subsidies Stimulate Regional Innovation Efficiency? Evidence from Germany
Broekel T. Do cooperative research and development (R&D) subsidies stimulate regional innovation efficiency? Evidence from Germany, Regional Studies. The subsidization of research and development (R&D) and R&D cooperation has gained in importance in recent years. Building on a rich panel dataset, covering 270 German labour market regions and four industries, it is shown that subsidies for R&D cooperation are a suitable policy measure for stimulat…
Knowledge networks in the Dutch aviation industry
The importance of geographical proximity for interaction and knowledge sharing has \nbeen discussed extensively in recent years. There is increasing consensus that \ngeographical proximity is just one out of many types of proximities that might be \nrelevant. We argue that proximity may be a crucial driver for agents to connect and \nexchange knowledge, but too much proximity between agents on any of the dimensions \nmight harm their innovative p…
What drives patent performance of German biotech firms? The impact of R&D subsidies, knowledge networks and their location
Applying a Non-parametric Efficiency Analysis to Measure Conversion Efficiency in Great Britain
In the literature on Sen’s capability approach, studies focusing on the empirical measurement of conversion factors are comparatively rare. We add to this field by adopting a measure of ‘conversion efficiency’ that captures the efficiency with which individuals convert their resources into achieved functioning. We use a non‐parametric efficiency procedure borrowed from production theory and construct such a measure for a set of basic functionings…
Regional Dynamics of Innovation
n The paper investigates the lead-lag relationships between the growth rates of patents, R&D, and employment for German regions over the period 1999-2005. The panel dataset employed includes information on four two-digit industries. The results obtained from a vector autoregression model show that an increase in patents is associated with subsequent growth of employment in the Medical and Optical Equipment industry as well as in the Electrics and…
