Tidskriftsartikel (refereegranskat)abstract
- A sustainable city combines stable long-term economic growth with a resilient ecological system. It is also a region of social sustainability with low levels of spatial segregation of different socio-economic groups. Spatial inclusion primarily involves provision of equalized city-wide access to territorial public goods. High durability of physical networks and buildings facilitates economic, environmental and social sustainability. This study shows that durability varies considerably between Asian, European and North American cities, with mean life expectancies of buildings that range from below 20 years in Chinese cities to over 100 years in European cities such as Paris. Urban planning principles that focus on the slow and steady expansion of accessibility and density within a durable built environment are consistent with general economic equilibria, while avoiding the pitfalls of political planning of the markets for private goods.

- A dynamic model that distinguishes between slow and fast processes shows that a triple helix model is impossible as a tool for promoting interdependencies among science, industry and government. We present a theorem to demonstrate that a triple helix strategy is logically impossible as a means of funding scientific research in universities. In spite of this logical impossibility, national and regional triple helix strategies to improve productivity and innovative capacity have been favoured by politicians of almost every ideological stripe. Coordination of science and industry by governments is not new; it harks back to the mercantilism of seventeenth-century Britain and France. In the twentieth and twenty-first centuries, triple helix policies have led to a short-term bias in favour of applied technological research. Several examples, ranging from the military use of scientists in World War II to Chinese high technology parks show how triple helix strategies tilt playing fields, suppress academic freedom0 and expose scientists to the whims of politicians.

Location and spatial clustering of artists

- Surveys of artists' location choices show that they disproportionately reside in large cities. This paper introduces a model that attempts to explain this urban preference. The model includes four factors: access to other artists; access to consumer demand; access to service jobs; and housing affordability. These four factors are combined in a spatial equilibrium model. An equilibrium spatial distribution of artists is derived from the model and is correlated with the actual distribution among Swedish municipalities. Subsequently, the model is used for an econometric estimation of factor effects. The results show that access to other artists and local access to service jobs are important localization factors. Educated labor used as a proxy for consumer demand has a significant effect on artists' location choices.

Gateways to the global economy
- 2000
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- In the post-industrial network economy, international gateway regions are becoming increasingly important. These gateway regions are the nodes (defined as a city or a city region) that act as saddle points between a region and the global economy. While gateway regions have existed ever since inter-regional trade was first practised, new non-trade networks, and the wider global economy, have made these regions more complex. The book includes discussions of infrastructure networks such as the internet and air transport, as well as networking activities such as long-distance scientific cooperation, financial networks and direct investments. The contributors have expertise in fields such as regional economics, economic geography, institutional economics and business administration.

- OBJECTIVE: To identify preliminary core sets of outcome variables for disease activity and damage assessment in juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM). METHODS: Two questionnaire surveys were mailed to 267 physicians from 46 different countries asking each member to select and rank the response variables used when assessing clinical response in patients with JSLE or JDM. Next, 40 paediatric rheumatologists from 34 countries met and, using the nominal group technique, selected the domains to be included in the disease activity and damage core sets for JSLE and JDM. RESULTS: A total of 41 response variables for JSLE and 37 response variables for JDM were selected and ranked through the questionnaire surveys. In the consensus conference, domains selected for both JSLE and JDM activity or damage core sets included the physician and parent/patient subjective assessments and a global score tool. Domains specific for JSLE activity were the immunological tests and the kidney function parameters. Concerning JDM, functional ability and muscle strength assessments were indicated for both activity and damage core sets, whereas serum muscle enzymes were included only in the activity core set. A specific paediatric domain called 'growth and development' was introduced in the disease damage core set for both diseases and the evaluation of health-related quality of life was advised in order to capture the influence of the disease on the patient lifestyle. CONCLUSIONS: We developed preliminary core sets of measures for disease activity and damage assessment in JSLE and JDM. The prospective validation of the core sets is in progress.

Infrastructural change and secular economic development
- 2008

- Long-term economic development is determined by changes to the infrastructure, especially material and non-material infrastructural networks that link agents in different locations. The infrastructure consists of the slowly changing, collective arena that supports production, exchange, and consumption, such as the built environment, transport networks, and institutions. In the short run the infrastructure can be regarded as fixed. Changes to the infrastructure are under normal conditions small enough to be disregarded by producers and consumers. With the creation of a critical link of a network, there will however be a revolutionary restructuring of the arena. Critical links are here defined as additions to infrastructural networks that create opportunities for new information and transport flows between previously unconnected regions. Such a revolutionary restructuring of infrastructural networks has been called a logistical revolution. Certain institutional pre-conditions are necessary for a logistical revolution, while the creation of a critical link is both a necessary and a sufficient condition. This paper discusses the three logistical revolutions that occurred in the 13th century, around 1600, and in the 19th century, which each had crucial similarities with the current “information revolution.”

Phase transitions as a cause of economic development
- 2019

- Economic development spans centuries and continents. Underlying infrastructural causes of development, such as institutions and networks, are subject to slow but persistent change. Accumulated infrastructural changes eventually become so substantial that they trigger a phase transition. Such transitions disrupt the prior conditions for economic activities and network interdependencies, requiring radically transformed production techniques, organizations and location patterns. The interplay of economic equilibria and structural changes requires a theoretical integration of the slow time scale of infrastructural change and the fast time scale of market equilibration. This paper presents a theory that encompasses both rapidly and slowly changing variables and illustrates how infrequent phase transitions caused four logistical revolutions in Europe over the past millennium.

Tidskriftsartikel (refereegranskat)abstract
- Europe has a long history as a global center of scientific research, but not all European regions are alike. Regions such as ile de France and the corridor that stretches from Cambridge to Oxford via London produce a disproportionate share of Europe's science output. An econometric analysis sheds light on the factors that explain the spatial distribution of European science. One result is that the regional volume of Web of Science publications depends on the regional number of researchers in higher education institutions. This is however not the only cause of high output. Universities and their surrounding regions are slowly evolving institutional structures. Some regions host universities that are more than 500 years old. A second key result is that an increase in the age of a region's oldest university is associated with greater output, other things being equal. Third, interregional accessibility via road, rail, and air networks is important for small regions, but not for large ones. Conversely, regional high-tech R&D employment is important for large but not for small regions.
