SPATIAL DEPENDENCE AND SPATIAL STRUCTURAL INSTABILITY IN APPLIED REGRESSION ANALYSIS*

The stability of regression coefficients over the observation set (“regional homogeneity”) is typically assessed by means of a Chow test or within a seemingly unrelated regression (SUR) framework. When spatial error autocorrelation is present in cross-sectional equations the traditional tests are no longer applicable. I evaluate this both in formal terms as well as empirically. I introduce a taxonomy of spatial effects in models for structural instability, and discuss its implication for testing. I compare the performance of traditional tests, robust approaches, maximum-likelihood procedures and pretest techniques by means of a series of simple Monte Carlo experiments.

MODERN MACROECONOMICS AND REGIONAL ECONOMIC MODELING*

ABSTRACT Despite a history of regional economic models being patterned after their national counterparts, modern macroeconomic methodology has yet to be fully embraced by regional scientists. In this paper, I argue that modern macroeconomic methodology has much to offer the field of regional economic modeling. For one, the empirical strategies used in implementing dynamic stochastic general equilibrium models provide insights into how regional computable general equilibrium models could be better parameterized and empirically verified. In addition, the structural macroeconomic approach more generally could be used to construct structural regional policy analysis models for use as alternatives to traditional regional models.     

Organising regional production networks in Southeast Asia: implications for production fragmentation, trade, and rules of origin

The globalisation of economic activities has fundamentally reshapedthe relationships between production and trade. The cross-borderproduction activities of transnational corporations (TNCs) havenot only deepened spatial divisions of labour, but also complicatedour understanding of international trade patterns. The developmentof intricate regional production networks by global corporationshas major implications for production fragmentation, internationaltrade, and rules of origin in the global economy. Empiricallygrounded in a study of regional production networks controlledby Singapore-based TNCs, this paper aims to make a modest contributionto the emerging literature on production fragmentation and rulesof origin. Based on an analysis of empirical data from a surveyof 63 parent Singapore-based manufacturing TNCs that have cross-borderoperations in Southeast Asia, I found that their spatial productionfragmentation is rather limited. Most of their Southeast Asiansubsidiaries cater to local markets, or manufacture components/partsfor the regional production facilities of their major globalcorporation customers. I also consider the implications forbusiness strategies and public policies in relation to productionfragmentation and rules of origin in Southeast Asia.     

Using measures of cost distance in the estimation of polity boundaries in the Postclassic Yautepec valley,Mexico

The reconstruction of polity boundaries is essential for the study of political evolution, but few enhancements to archaeological boundary estimation methods have been proposed in recent years. New techniques of terrain modeling and geographical analysis provide the means to augment traditional methods of boundary estimation. In this paper, I review archaeological methods for estimating the spatial location of boundaries between independent polities and ways to modify these methods to explore the processes of political expansion in the evolution of complex societies. I demonstrate several of these methods using data from Postclassic polities in the Yautepec valley, Morelos, Mexico. Through time, seven independent polities were founded, expanded, and were ultimately incorporated within two levels of regional political administration. I apply new quantitative methods for the estimation of polity territories and explore the processes that resulted in the formation of a regional polity. The resulting boundaries are objective estimates of the location of borders based on energetic efficiency that can be systematically tested against theoretical models. These estimated boundaries provide a basis for exploring the social meaning of territorial divisions. Additionally, energetic boundaries provide a means for delineating local zones for landscape utilization and comparative analyses.     

European spatial planning reloaded: Considering EU enlargement in theory and practice

The territorial expansion of the European Union (EU) to the new central and eastern European member states raises difficult challenges for European spatial planning. In almost the same manner as structural policy, the conceptual side of European spatial planning has to acknowledge that with enlargement a quantum leap regarding its politics and policy is about to occur. While reflecting on discussions about EU's regional policy and spatial planning on the European level, and sketching a theoretical background, this paper proposes a new way of conceptualizing European spatial planning, taking central and eastern European spatial planning—perhaps as a new epistemic community—into consideration.     

EUROPEAN UNION REGIONAL PRODUCTIVITY DYNAMICS: A “DISTRIBUTIONAL” APPROACH*

ABSTRACT Working within the “distributional approach,” this research offers evidence of past and future polarization in aggregate regional labor productivity in EU‐15. This finding is robust to alternative definitions of the spatial units used and does not appear to be the result of regional structural change. Spatial effects are found but are of rather localized nature. Turning to separate sectoral analyses suggests that past and future polarization in labor productivity across European regions may be associated with regional productivity differences in the services sectors.     

STRUCTURAL FEATURES OF WEST EDMONTON MALL

This article addresses the question of how West Edmonton Mall (wem) may be a new and distinctive component of retail spatial structure by analysing the retail and service attributes of the mall in the context of (I) Edmonton's retail structure at the regional shopping centre level, and (2) the internal structure of the mall. It is suggested that wem has added a new level to Edmonton's retail hierarchy, rivalling the downtown as the city's primate centre. The analysis of tenant changes leads to the conclusion that these changes tend to reflect a movement from unconventional to conventional tenant mix, and that wem is not much different, other than in sheer size, from most large regional shopping centres. The only unique structural characteristic appears to be the existence of enclaves not usually found in other malls.     

Location and Growth in the Brazilian Northeast

Abstract Clustering of economic performance across jurisdictions has generated considerable research on the spillovers and linkages among geographical neighbors. Much of this work, however, has been aspatial, implying that the influence of location attributes on growth has been largely ignored. In this paper, we examine the contribution of location to regional economic growth using municipio‐level data for the Brazilian Northeast—a historically lagging region of the country. We test if productivity among northeastern municipios is converging to a steady state and whether spatial externalities are linked to productivity growth in individual municipios. We find that, conditional on structural characteristics, productivity among municipios is converging at about 3 percent per year. Further, productivity in individual municipios is positively associated with own‐structural characteristics but negatively associated with productivity growth in neighboring municipios. This means that there are negative spatial externalities coming from productivity improvements in neighboring regions.     

DECOMPOSING REGIONAL EFFICIENCY*

ABSTRACT Applying an outlier robust extension of the data envelopment analysis (DEA) followed by a geoadditive regression analysis, this study identifies and decomposes the efficiency of 439 German regions in using infrastructure and human capital. The findings show that the regions’ efficiency is driven by a spatial and a nonspatial, arguably structural factor. As a consequence, concrete regional funding schemes, shaped by best practice results, might not be appropriate for all regions. Instead, a more differentiated funding scheme that accounts for both spatial and structural factors seems more promising.     

The Making of an Internal Frontier Settlement: Archaeology and Historical Process in Osun Grove (Nigeria), Seventeenth to Eighteenth Centuries

The historical, material, and spatial processes that defined the formative settlement practices in Early Osogbo (southwest Nigeria), a seventeenth- to early eighteenth-century frontier community, is the subject of this article. I use different datasets, including the spatial layout of the site, the archaeological depositional sequence, diverse artifact categories, and oral historical sources to engage Igor Kopytoff’s Internal African Frontier thesis. In this article, I argue against Kopytoff’s conceptualization of the frontier as a conservative space that relied on innovations from the metropolis. Instead, I demonstrate that Early Osogbo was a dynamic formative settlement in an internal Yoruba regional frontier whose material life was not a mere copy of a metropolis’s. Instead, this emerging community was characterized by diversity, complexity, experimentation, and newness that resulted from local forces of migration, frontier social networks, and regional exchange systems involving several spheres of interstitial frontiers and multiple metropolises. Contrary to the metropolis-frontier pattern of migration that informed Kopytoff’s Internal African Frontier thesis, Early Osogbo was originally created by frontier-frontier migrations before it became a site for intermetropolis contestation. The article underscores the need to bring conceptual clarity to the study of frontier processes, arguing that different historical contexts, migration patterns, and regional political frameworks produced different kinds of frontiers such as crossroads, boundary, colony, and cultural frontiers. The archaeological profile of Early Osogbo demonstrates that the settlement was a crossroads frontier community.     

Exploring Goodness-of-Fit and Spatial Correlation Using Components of Tango's Index of Spatial Clustering

The ability to detect anomalies such as spatial clustering in data sets plays an important role in spatial data analysis, leading to interest in test statistics identifying patterns exhibiting significant levels of clustering. Toward this end, Tango (1995) proposed a statistic (and its associated distribution under a null hypothesis of no clustering) assessing overall patterns of spatial clustering in a set of observed regional counts. Rogerson (1999) observed that Tango's index may be decomposed into the summation of two distinct statistics, the first mirroring standard tests of goodness-of-fit (GOF), and the second an index of spatial association (SA) similar to Moran's I . In this article, we investigate the effectiveness of Rogerson's expression of Tango's statistic in separating GOF from SA in data sets containing clusters. We simulate data under the null hypothesis of no clustering as well as two alternative hypotheses. The first alternative hypothesis induces a poor fit from the null hypothesis while maintaining independent observations and the second alternative hypothesis induces spatial dependence while maintaining fit. Using Rogerson's decomposition and leukemia incidence data from upstate New York, we show graphically that one is unable to statistically distinguish poor fit from autocorrelation.     

Regulating Regional Uneven Development and the Politics of Reconfiguring Belgian State Space

Abstract: This article mobilises a strategic‐relational approach to state spatial restructuring to overcome the weaknesses of the conventional “New Regionalist” account in economic geography of the resurgence of the region as a strategic site for economic governance. Focusing on hegemonic projects and the shifting nexus of spatial dependencies and engagements through which these are reproduced, undermined and transformed, the role and geography of political agency in state spatial restructuring is highlighted. To illustrate this point, I analyse the construction of new regional state spaces in Belgium, paying particular attention to the hegemonic projects that create a social basis for particular state spaces, the construction of collective agency on different scales (Belgian‐national and Flemish‐regional) and the various ways in which these processes are informed by pre‐existing state spatial and scalar selectivities.     

How to improve the quality of life in peripheral and lagging regions by policy measures? Examining the effects of two different policies in Germany

Peripheral regions commonly appear to be less attractive to live in and policymakers all over the world are applying various measures to make them more attractive. This paper analyzes the effects of two very different measures: The German municipal fiscal equalization scheme and the German structural funds for economically weak areas (GRW). It focusses on the impact on perceived quality of life, measured through interregional migration between German labor market regions. Using a spatial vector autoregressive panel model, we find evidence that equalization transfers have a significant positive impact on regional net migration and contribute to the aim of regional equity. These effects are especially found for regions with low endogenous fiscal capacities. GRW funding reveals no significant effects on net migration rates in total, but short-term effects in rural regions.

Regional Devolution and Regional Economic Success: Myths and Illusions about Power

The proposition that regional devolution in and of itself will lead to economic success has become deeply embedded in beliefs and policy discourses about the determinants of regional prosperity, and in turn has led to political demands for such devolution. In this paper I seek critically to examine such claims, using the case of the north‐east of England as the setting for this examination. The paper begins with some introductory comments on concepts of power, regions, the reorganization of the state and of multi‐level governance, and governmentality, which help in understanding the issues surrounding regional devolution. I then examine the ways in which north‐east England was politically and socially constructed as a particular type of region, with specific problems, in the 1930s — a move that has had lasting significance up until the present day. Moving on some six decades, I then examine contemporary claims about the relationship between regional devolution and regional economic success, which find fertile ground in the north‐east precisely due to its long history of representation as a region with a unified regional interest. I then reflect on the processes of regional planning, regional strategies and regional devolution, and their relationship to regional economic regeneration. A brief conclusion follows, emphasizing that questions remain about the efficacy of the new governmentality and about who would be its main beneficiaries in the region. The extent to which devolution would actually involve transferring power to the region and the capacity of networked forms of power within the region to counter the structural power of capital and shape central state policies remains unclear.

Towards a network of regions: The United States of Europe

Starting from the changing role of governments in planning (physical, environmental, economic, etc.), this paper calls attention to the drastic structural changes taking place in the regional scene after the transition towards market orientation and global competitiveness. The main focus is on European developments. In addition to économie forces, two phenomena will be highlighted, namely, the transition towards a network economy and the profound technological changes taking place at the regional and urban level Particular attention will be devoted to European spatial dynamics in a networked society. Various new geographical configurations and maps of Europe will be shown, followed by some exploratory remarks on future trends. The main message of the paper is that transport planning in Europe needs to be integrated with the emerging new economic networks. The paper ends with some policy conclusions.     

Arms Racing in ‘Space’: Spatial Modelling of Military Spending around the World

This paper builds on previous research into determinants of military spending by examining global and local spatial effects. Other research has examined the effects of regional differences and neighbours' spending levels with standard econometric techniques. This paper uses spatial econometrics to gain a better understanding of the influence of location and distance on levels of defence spending. I find that a spatial lag specification provides much more robust evidence of arms racing and security dilemma dynamics than previous studies. These basic dynamics have been difficult to detect empirically without the context and nuance introduced by spatial modelling. The paper represents a first cut at the topic, but two specific findings emerge. First, globally there is positive spatial correlation (nearby states have similar levels of spending). This conforms to arms racing and security dilemma expectations. And, second, locally there is variation in the patterns of spatial clustering across broad international regions (e.g. Europe, Asia etc.). The second finding supports previous research suggesting important qualitative regional variation in patterns of defence spending and international conflict. The models also confirm the effects of political regime type and interstate war on defence spending, and are robust to the inclusion of a temporally lagged dependent variable.
