THE DETERMINANTS OF LOCALIZATION AND URBANIZATION ECONOMIES: EVIDENCE FROM THE LOCATION OF NEW FIRMS IN SPAIN

The objective of this paper is to analyze why firms in some industries locate in specialized economic environments (localization economies) while those in other industries prefer large city locations (urbanization economies). To this end, we examine the location decisions of new manufacturing firms in Spain at the city level and for narrowly defined industries. First, we estimate firm location models to obtain estimates that reflect the importance of localization and urbanization economies in each industry. Then, we regress these estimates on industry characteristics related to the potential importance of labor market pooling, input sharing, and knowledge spillovers. Urbanization effects are high in knowledge‐intensive industries, suggesting that firms locate in large cities to benefit from knowledge spillovers. We also find that localization effects are high in industries that employ workers whose skills are more industry‐specific, suggesting that industries locate in specialized economic environments to share a common pool of specialized workers.     

ECONOMIC GEOGRAPHY OF FIRMS AND SKILLED LABOR*

ABSTRACT This paper investigates the relationship between firm location and skilled‐labor location. While existing new economic geography (NEG) models could not explicitly analyze the relationship due to their assumptions, I construct a new NEG‐type model allowing for different location dynamics of firms and skilled labor for this objective. The main results are as follows. First, a relatively large pool of skilled labor attracts firms when trade costs are small, while it might repel firms when trade costs are sufficiently large. Second, assuming that skilled workers are mobile between regions, the model shows that skilled workers agglomerate faster than firms with decreasing trade costs. Third, the model supports the hypothesis that firms follow skilled labor rather than the reverse. These results are consistent to Indian and Chinese experiences, and some “creative‐class” or “skilled‐city” stories.     

A city transformed: manufacturing districts and suburban growth in Montreal, 1850–1929

This paper examines the development of Montreal's industrial geography between 1850 and 1929. It is argued that a decisive feature of the evolution of the city's industrial and social landscape was the emergence of industrial districts on the moving urban frontier. The formation of new suburban districts and the reorganization of existing industrial districts were part of a developing urban spatial division of manufacturing. Three critical features underlay the restructuring of Montreal's industrial geography after 1850. Waves of industrial expansion and the development of a range of production trajectories altered the parameters of location within the city. Working-class suburbanization provided the requisite labour force for firms locating on the periphery. Local political and economic alliances created the physical, ideological and legal structures for suburban industrial growth and the rearrangement of the urban fabric.     

Unfolding the relationship between resilient firms and the region

ABSTRACT

This research explores organizational resilience in four manufacturing firms in four different regions of Norway. While regional resilience has gained attention in research, there have been few studies with a micro-level focus, investigating firms and their distinctive features of resilience. We chose a qualitative multiple-case study approach and employed a critical incident technique to study resilience in selected firms that had experienced external shocks and shifts in regard to changing markets, globalization and advances in technology. Each, however, had managed to continually develop resilience capacity over time. Our framework considered three dimensions of organizational resilience: the cognitive, the behavioural and the contextual. We address how resilience is sustained over time, the evolutionary nature of organizational resilience in firms and how resilient firms relate to the region. We found that all three dimensions of resilience capacity were evident in each firm, but appeared as a complex and unique blend. Furthermore, each dimension was supported by regional ties and affiliations. The findings suggest that organizational resilience is a dynamic capability conditioned by firm–region interactions, which are cultural, social and economic. Regional resilience is built through the contribution of the firm to the economic and social systems of the region.

Multi-Firm City Versus Company Town: A Micro Foundation Model of Localization Economies

When do we have a company town and when do we have a multi‐firm city? In this paper I analyze the impact of public infrastructure investment decisions on types of cities in a decentralized urban system. This is done in a one‐sector spatial general equilibrium model of a closed economy. Investment in public infrastructures reduces the fixed set up cost of all firms within the city resulting in multi‐firm cities. Thus, in this approach localization economies are modelled explicitly instead of assuming that larger industrial size within the city enhances productivity. On the other hand, when the infrastructure is not provided, a company town will be formed by a developer because of the fixed cost required by each firm. The decision of whether to invest in the provision of public infrastructures depends on the type of city that will provide households with the highest utility. This paper characterizes the conditions that lead to each of the two equilibrium configurations.     

TRAFFIC CONGESTION,POLYCENTRICITY, AND INTRAURBAN FIRM LOCATION CHOICES: A NESTED LOGIT MODEL FOR THE LOS ANGELES METROPOLITAN AREA

This study empirically investigates traffic congestion effects on agglomeration through the lens of firm location decisions. A discrete choice model is applied to examine new establishments’ location choices within the Los Angeles metropolitan area. Employment centers are defined as the choice set to explore the nature and role of intraurban agglomerations. The results show that metro‐wide congestion negatively affects the location choices of firms in the high‐order office‐related activities, while local congestion have positive impacts on those firms’ location decisions. In contrast, firms in production‐related activities are positively influenced by regional congestion but are negatively affected by local congestion levels.     

EMBEDDED AND DISEMBEDDED PRACTICE IN THE FIRM–PLACE NEXUS: A STUDY OF TWO WORLD‐LEADING MANUFACTURERS OF SKI EQUIPMENT IN THE LILLEHAMMER SKI CLUSTER

Studies of agglomerations and clusters in economic geography anticipate strong interdependency between firms and places. However, despite the extensive literature, we lack a coherent micro‐theoretical foundation. The relationship between the rationales and practices of firms remains somewhat unspecified. In this article, we analyse the diversity of rationales and practices in a firm–place nexus. Possible rationales for firm practice are outlined, examining the assumptions of three, main theoretical perspectives in economic geography. This microeconomic approach is applied through an analysis of the two key firms in the Lillehammer skiing industry cluster in Norway. The study contributes to a more nuanced understanding of how the agency of firms influence and are influenced by co‐location.     

Digital gravity? Firm birth and relocation patterns of young digital firms in Germany

This paper analyses the spatial patterns of young (<10 years) digital firms in Germany between 2008 and 2017 on county level. Determinants of firm birth locations as well as relocations are considered jointly to understand differences in location choices within firms' life cycles. I match commercial register data of 107,321 firms with county-level administrative data to capture local characteristics. Using an OLS model with fixed effects, I find that the local knowledge base—that is, universities, research institutes, and colocated incumbents—are significant key determinants of digital firm birth when controlling for a host of local characteristics. My results indicate that for five firms per 1000 inhabitants, there is around one firm birth. Second, using a fixed effects gravity model for the analysis of relocations, I find that the most dominant explanatory factor for firm relocation across specifications is distance, that is, relocation costs. Relocation flows are more than twice as high to neighboring counties relative to other locations which shows that digital firms are not as footloose as their business model may suggest. Jointly, my results reflect economic activity's regional persistence, particularly for new firms. My paper provides evidence for policies targeting homogenous digital clusters based on strong colocation and that digital economic activity is not shifted over long distances, but the regional entrepreneurship capital is crucial for local growth.     

The Social,Political and Economic Functions of Courtyard Houses in Umm Qais,Northern Jordan

The courtyard house represents a model for the collective social, political and economic functions of the peasant community during the nineteenth century in northern Jordan. Ethnography, landscape and space syntax analyses were used to reconstruct these functions in the area of Umm Qais, Jordan. The results show that the various social systems in the study area were centered on kinship leaving projections in the form and order of the various spaces in the courtyard house. The nature of the landscape was a determinant factor in the location of courtyard houses, which was triggered by the climate regime in the area.

Negotiating spatial identities: mobile perspectives on street life in uganda

Previous geographical research with street children has principally focused on their micro-geographies in the city. This paper draws on nomadic and episodic processes of homeless mobility, to explore street children's geographies from a wider social, spatial and temporal perspective. By examining street life in Kampala, Uganda as a continued negotiation of public/private and street/non-street locations, the fluid nature of street children's identity is illustrated. Over time, movement between spaces, such as divergent city niches, institutions, homes and other towns, is often subject to power relations operating in street/non-street spaces with each requiring conformity to a different set of values and behaviours. The paper demonstrates how this results in children's street identity changing as they move through the street life path.

Different typologies of ‘co-working spaces’ and the contemporary dynamics of local economic development in Rome

ABSTRACT

Co-working spaces of different types are emerging as new economic and social intermediaries in the contemporary process of urban regeneration and urban economic growth. Despite their relevance, literature still fails to explore their role in the surrounding local economy. This paper intends to fill that gap, providing empirical evidence from the city of Rome and suggesting new policy perspectives. First, a taxonomy of the different spaces is provided, assessing their role in the related socio-economic ecosystem. Three main typologies have been identified: CWS1 acting as a ‘social incubator’ with an educational role and closer links to local authorities, CWS2 or ‘start-up incubator’ providing economic and technical support to the entrepreneurs-to-be, CWS3 or ‘real estate incubator’ which are mainly a commercial product. Their locational patterns are then discussed, highlighting the planning implication of their settlement in some in-between urban peripheral areas of Rome. Finally, suggestions for the creation of public/private partnerships or ‘social leases’ are proposed, foreseeing the integration of such spaces in the local offer of amenities. The current research paves the way for further discussion on the renewal of cities’ governance tools, processes of urban regeneration and policies tackling the new urban entrepreneurial class.     

The Net Effects of Large Plant Locations and Expansions on County Employment*

This paper argues that the net economic impact of new firm locations or expansions is determined by a multitude of opposing forces. Using a unique database, I set out to evaluate the net effects of these opposing forces by looking at the net change in local employment and population arising from large (greater than 300 new jobs) firm locations or expansions in the State of Georgia. The analysis suggests that the employment multipliers associated with new firm locations are much less than one; that is, the net employment effect of a large firm opening is smaller than the gross employment impact. This result is consistent with other empirical economic impact studies, which find multipliers much smaller than those of typical input–output models, often less than unity, and a previous study showing little net effect of large plant openings. Expansions of existing establishments are shown to have substantial multiplicative effects, however, with an average employment multiplier of 2.0. I discuss possible reasons for differential impacts across new and expanding firms, focusing on the nature of the firms. Differences in net impact across industries and high‐tech versus low‐tech firms also is evaluated. I find that the impact of large firm locations or expansions on population in the resident county generally is negative, but positive for the broader region encompassing the county of location and its contiguous neighbors.     

CAN REGIONALIZATION OF LOCAL PUBLIC SERVICES INCREASE A REGION'S WEALTH?*

ABSTRACT. In the presence of agglomeration and congestion externalities the sequence of location choices made by firms results in an inefficient distribution of economic activity, since individual firms do not bear the congestion costs they impose on other firms. In this paper, we model the interaction of public authority service strategies and firm location choices. We show that a self-interested regional authority can effect a welfare-improving distribution of economic activity when compared with an economy without an authority or an economy with local authorities. However, we also show that the conditions under which the authority would induce a welfare enhancing distribution depends on the authority's strategic posture, as well as the nature and size of public subsidies for the authority. The conditions necessary for a regional authority to choose an efficiency enhancing strategy may be difficult to achieve.     

Understanding Spatial Differentiation in Urban Decline Levels

The economic and demographic changes currently manifest in many Western cities—referred to as urban decline or urban shrinkage—are receiving increased attention in public and academic debates. Although the general processes driving these changes have been identified, such processes cannot explain why regions and cities which have been exposed to similar processes still differ in their economic and demographic developments. This Western European and US-based literature review attempts to answer the question of how this interregional and intraregional variation in levels of economic and demographic decline can be understood. It is argued that the degree to which wider societal forces (such as deindustrialization, changes in international and domestic migration and changing fertility levels) impact on a particular area depends on how these forces are filtered, first, through the institutional and, second, the spatial context that the region or city is located in. To understand the differences between the cities within one region (being part of the same institutional and spatial contexts), we need to descend to the city level and take account of the local (dis)amenities, comprising its physical, social and economic assets, and the influence of (the place characteristics of) other cities in the vicinity and the socio-political framework.     

THE EFFECTS OF ZONING IN SPATIAL COMPETITION

ABSTRACT This paper considers a location model to illustrate the effect of zoning on competition. A planner is in charge of designing a city in a circular space where firms and consumers are located on different sides. With this type of market configuration, equilibrium in location under concave transport costs is proved. Then, a welfare function with different weights attached to consumer and firm surpluses is introduced to highlight zoning regulation as an influential competition policy tool. Depending on the regulator's political profiles and the demand, it is shown that zoning can lead to strong, weak, or moderate competition.     

Knowledge Production,Urban Locations and the Importance of Local Networks

This paper analyses the relationship between knowledge production and urban locations in industrial design, a knowledge-intensive business service (KIBS). KIBS concentrate in urban locations. This is often explained by the co-location of client firms and market access in large cities. Recent research on knowledge production, however, reveals that knowledge productive networks are significant for both the competitiveness and location of KIBS. Thus, to understand the urban location of industrial design, it is important to analyse how knowledge production is organized within the industry. Industrial design is concentrated in urban locations, but most of its clients are located elsewhere. Hence, it seems that industrial design firms concentrate in urban locations mainly because their knowledge networks include specific types of formal and informal local social networks.
