The Aims and Scope of Evolutionary Economic Geography

This aim of this paper is to present the objectives and scope of an evolutionary approach to economic geography. We argue that the goal is not only to utilise the concepts and ideas from evolutionary economics (and evolutionary thinking more broadly) to help interpret and explain how the economic landscape changes over historical time, but also to reveal how situating the economy in space adds to our understanding of the processes that drive economic evolution, that is to say, to demonstrate how geography matters in determining the nature and trajectory of evolution of the economic system. We will argue that evolutionary economic geography is concerned with the spatialities of economic novelty; with how the spatial structures of the economy emerge from the micro-behaviours of economic agents; with how, in the absence of central coordination or direction, the economic landscape exhibits self-organisation; and with how the processes of path creation and path dependence interact to shape geographies of economic development and transformation, and why and how such processes may themselves be place dependent. Economic transformation proceeds differently in different places, and the mechanisms involved neither originate nor operate evenly across space. Our concern is both with the ways in which the forces making for economic change, adaptation and novelty shape and reshape the geographies of wealth creation, work and welfare, and with how the spatial structures and features so produced themselves feed back to influence the forces driving economic evolution. In the final part, we summarize a number of papers that have contributed to evolutionary economic geography, and which will be published in The Handbook on Evolutionary Economic Geography that is edited by the two authors, and forthcoming at Edward Elgar.evolutionary economic geography, industry location, geography of networks, institutions, agglomeration economies

Regional Economic Resilience, Hysteresis and Recessionary Shocks

The notion of 'resilience' has recently risen to prominence in several disciplines, and has also entered policy discourse. Yet the meaning and relevance of the concept are far from settled matters. This paper develops the idea of resilience and examines its usefulness as an aid to understanding the reaction of regional economies to major recessionary shocks. But in so doing, it is also argued that the notion of resilience can usefully be combined with that of hysteresis in order to more fully capture the possible reactions of regional economies to major recessions. These ideas are then used as the basis for a preliminary empirical analysis of the UK regions.Regional economic growth, Recessionary shocks, Resilience Hysteresis

The International Bathymetric Chart of the Arctic Ocean (IBCAO): An Improved Morphological Framework for Oceanographic Investigations

The IBCAO initiative set out in late 1997 to assemble and merge all available bathymetric observations from northern regions, with the intent of constructing a reliable and up-to-date portrayal of the Arctic seabed in digital and printed form. In early 2000, a provisional grid and map were placed in circulation for public review and comment. Available for free downloading from a website hosted by the U.S. National Geophysical Data Center, these products won immediate acceptance from a broad spectrum of Arctic investigators who recognized the potential worth of the new information in a variety of applications ranging from straightforward map production to analysing the influence of underwater topography on ocean circulation. At the same time, error reports and new data sets were being forwarded to the creators of IBCAO, so that by the middle of 2002 a new and more definitive grid was ready to be placed into circulation. This was soon followed by the construction of a prototype shaded relief map that has been proposed as a successor to Sheet 5.17 of the General Bathymetric Chart of the Oceans (GEBCO)

Forms of Emergence and the Evolution of Economic Landscapes

Over the past two decades, the notion of ÔemergenceÕ has attracted increasing attention and controversy across the social sciences, as par of a growing interest in the applicability of complexity theory to socio-economic-political systems. Within this context, as economic geographers, our concern in this paper is with the usefulness of the idea of emergence for studying the economic landscape and its evolution. We examine three ÔordersÕ of emergence, and focus attention especially on the third type, Ôdevelopmental or evolutionaryÕ emergence. Despite its limitations, the notion of third order emergence is a potentially valuable organizing concept in economic geography. It provides a framework for exploring how it is that the spatial forms of the economy - clusters, regions, firm networks and so on Ð are recursively related to economic action.Emergence, Supervenience, Downward causation, Evolution, Economic landscape

Deconstructing Clusters: Chaotic Concept or Policy Panacea

Recently there has been growing interest in local industrial agglomeration and specialisation, by economic geographers, economists and policy-makers. Michael Porter's work on 'clusters' has proved by far the most influential to have emerged. His 'cluster theory' has become the standard concept in the field, and policy-makers worldwide have seized upon it as a tool for promoting national, regional and local competitiveness, innovation and growth. However, seductive though the cluster concept is, there is much about it that is problematic, and the rush to employ 'cluster ideas' has run ahead of many fundamental conceptual, theoretical and empirical questions. Our aim is to deconstruct the cluster concept in order to reveal and highlight our concerns relating to the definition of the cluster concept, its theorisation, its empirics, the claims made for its benefits and advantages, and its use in policy-making.business location, clusters, chaotic concept, cluster theory, cluster policy

Complexity Thinking and Evolutionary Economic Geography

Thus far, most of the work towards the construction of an evolutionary economic geography has drawn upon a particular version of evolutionary economics, namely the Nelson-Winter framework, which blends Darwinian concepts and metaphors (especially variety, selection, novelty and inheritance) and elements of a behavioural theory of the firm. Much less attention has been directed to an alternative conception based on complexity theory, yet in recent years complexity theory has increasingly been concerned with the general attributes of evolutionary natural and social systems. In this paper we explore the idea of the economic landscape as a complex adaptive system. We identify several key notions of what is being called the new ‘complexity economics’, and examine whether and in what ways these can be used to help inform an evolutionary perspective for understanding the uneven development and adaptive transformation of the economic landscape.complexity theory, evolution, economic landscape, networks, emergence, regional adaptation

Conceptualising Cluster Evolution: Beyond the Life-Cycle Model?

Although the literature on the evolution of industrial clusters is not vast, a preferred approach has already become evident, based around the idea of a cluster 'life-cycle'. This approach has several limitations. In this paper we explore a different conception of cluster evolution drawing on the 'adaptive cycle' model that has been developed in evolutionary ecology. Using this model, cluster evolution is viewed as an adaptive process with different possible outcomes based on episodic interactions of nested systems. Though not without limitations, this approach offers greater scope as a framework for shaping the research agenda into the evolution of clusters.Clusters, Evolution, Life-cycle model, Complex systems, Adaptive cycle model

How do regions diversify over time? Industry relatedness and the development of new growth paths in regions

The question of how new regional growth paths emerge has been raised by many leading economic geographers. From an evolutionary perspective, there are strong reasons to believe that regions are most likely to branch into industries that are technologically related to the preexisting industries in the region. Employing a new indicator of technological relatedness between manufacturing industries, we analyze the economic evolution of 70 Swedish regions during the period 1969-2002 using detailed plant-level data. Our analyses show that the long-term evolution of the economic landscape in Sweden is subject to strong path dependencies. Industries that were technologically related to pre-existing industries in a region had a higher probability to enter the region, as compared to unrelated industries. And unrelated industries had a higher probability to exit the region. Moreover, we found that industrial profiles of Swedish regions showed a high degree of technological coherence. Despite substantial structural change, this coherence was very persistent over time. Our methodology also proved useful when focusing on the economic evolution of one particular region. Our analysis showed that the Linkˆping region increased its industrial coherence during 30 years, due to the entry of industries that were closely related to its regional portfolio on the one hand, and the exit of industries that were technologically peripheral to its regional portfolio on the other hand. In sum, we find systematic evidence that the rise and fall of industries is strongly conditioned by industrial relatedness at the regional level.technological relatedness, related variety, regional branching, regional diversification

Hypsometry, Volume and Physiography of the Arctic Ocean and Their Paleoceanographic Implications

Recent analyses of the International Bathymetric Chart of the Arctic Ocean (IBCAO) grid model include: Hypsometry (the distribution of surface area at various depths); ocean volume distribution; and physiographic provinces [Jakobsson 2002; Jakobsson et al., in press]. The present paper summarizes the main results from these recent studies and expands on the paleoceanographic implications for the Arctic Ocean, which in this work is defined as the broad continental shelves of the Barents, Kara, Laptev, East Siberian and Chukchi Seas, the White Sea and the narrow continental shelves of the Beaufort Sea, the Arctic continental margins off the Canadian Arctic Archipelago and northern Greenland. This, the Worlds smallest ocean, is a virtually land-locked ocean that makes up merely 2.6 % of the area, and 1.0 % of the volume, of the entire World Ocean. The continental shelf area, from the coastline out to the shelf break, comprises as much as 52.9 % of the total area in the Arctic Ocean, which is significantly larger in comparison to the rest of the world oceans where the proportion of shelves, from the coastline out to the foot of the continental slope, only ranges between about 9.1 % and 17.7 %. In Jakobsson [2002], the seafloor area and water volume were calculated for different depths starting from the present sea level and progressing in increments of 10 m to a depth of 500 m, and in increments of 50 m from 550 m down to the deepest depth within each of the analyzed Arctic Ocean seas. Hypsometric curves expressed as simple histograms of the frequencies in different depth bins were presented, along with depth plotted against cumulative area for each of the analyzed seas. The derived hypsometric curves show that most of the Arctic Ocean shelf seas besides the Barents Sea, Beaufort Sea and the shelf off northern Greenland have a similar shape with the largest seafloor area between 0 and 50 m. The East Siberian and Laptev seas, in particular, show area distributions concentrated in this shallow depth range, and together with the Chukchi Sea they form a large flat shallow shelf province comprising as much as 22 Besides being the world’s smallest ocean with the by far largest shelf area in proportion to its size, the Arctic Ocean is unique in terms of its physiographic setting. The Fram Strait is the only real break in the barrier of vast continental shelves enclosing the Arctic Ocean. The second largest physiographic province after the continental shelves consists of ridges, which is in contrast to the rest of the World’s oceans where abyssal plains dominate. As much as 15.8 % of the area is underlain by ridges indicating the profound effect they have on ocean circulation
