The model-based enquiry depends on the form in which models are formulated and represented. When economists select a model as an efficient reasoning tool, they may first consider the type of model whose inherited epistemic virtue and reasoning rules best fits their needs. This chapter studies the dependence between the different forms of models and scientific knowledge by considering a particular form of model, that is, the diagram. This chapter draws from the history of location theory, which provides us with an example of how economists reasoned with diagrams, how their particular geometric shapes became an idealized landscape, and how they reasoned into them to account for actual spatial patterns of economic activity providing the opportunity for policy advice. Three different diagrams are examined: Johann Heinrich von Thünen’s concentric rings of agricultural land use, Alfred Weber’s triangles of industrial locations, and Walter Christaller’s hexagons of market area.

States that the choice of a store’s location is considered to be the single most important decision a retail organization has to make, and that location is seen as a critical factor of success. Reviews the literature on store location models and how grocery retailers in the UK assess store location sites in terms of site potential and the location models that they apply to these potential sites. Also develops and highlights issues of the use of existing store location models to geographical areas of Eastern and Central Europe.

The purpose of this study is to assess the evolution of restaurant locations in the city of Hamilton over a 12‐year period (1996 to 2008) using GIS techniques. Retail theories such as central place, spatial interaction and principle of minimum differentiation are applied to the restaurant setting.

A database of restaurants was compiled using the NZ yellow pages and contained 981 entries that consisted mainly of location addresses and types of cuisine. This paper focuses on locational patterns only.

A process of geo‐coding and clustering enabled the identification of two clustering periods over 12 years for city restaurants, indicating locational patterns of agglomeration within a short walking distance of the CBD and spill over effects to the north of the city.

The data do not allow statistical analysis of the variables causing the clustering but offer a visual description of the evolution. Explanations are offered on the possible planning regimes, retail provision and population changes that may explain this evolution.

The findings allow identification of land use patterns in Hamilton city and potential areas where new restaurants could be developed. Also, the usefulness of geo‐coded data in identifying clustering effects is highlighted.

Existing location studies relate mostly to site selection criteria in the retailing industry while few have considered the evolution of restaurant locations in a specific geographic area. This paper offers a case study of Hamilton city and highlights the usefulness of GIS techniques in understanding locational patterns.

This chapter presents projections of residential development in Wappinger Creek watershed of Dutchess County, New York in the Hudson River Valley. A spatial econometric model is developed based on data from a geographical information system (GIS) of county-level socio-economic trends, tax parcel attributes, town-level zoning restrictions, location variables, and bio-geophysical constraints including slope, soil type, riparian and agricultural zones. Monte Carlo simulation is employed to distribute spatially explicit projections of land-use change under various residential development scenarios. Scenario analysis indicates the likelihood of continued residential, decentralized development patterns in formerly agricultural and forested parcels. Policy scenarios demonstrate possible courses of action to direct development and protect watershed health.

To extend the research focuses of downtown business districts beyond the urban planning literature through application of the resource‐based theory of the firm. Downtowns may act like firms (with a collection of SBUs), and therefore should possess resources that provide competitive advantages.

A multi‐method approach (focus groups; survey) is used to examine, a priori, the resources that provide competitive advantage for downtowns, including brand identity, business mix and community characteristics. Structural equation modeling is used to test the measurement of the constructs as well as estimate the effects of those constructs on downtown success. The data were collected from business owners within 11 downtown business districts in the US Midwest.

Confirmatory factor analyses reveal that brand identity, business mix and community characteristics are three distinct measures of downtown resources. Brand identity was found to have a significant and positive effect on downtown success. Though the literature points to the importance of both business mix and community characteristics, these did not have a significant effect on downtown success.

Brands in general are posited to be less mobile than other firm resources, and thus may provide a more sustainable competitive advantage. By combining diverse areas of study, operationalizing new constructs, and testing measures, both the resource‐based view (RBV) and brand research are extended.

Since most downtown business districts (and the small businesses therein) have finite resources, to identify those which provide the most sustainable competitive advantage is critical to success. In this study, brand identity is the most important resource a downtown can possess.

This research moves the study of brands beyond “product” towards the concept of place branding. It extends the RBV framework to conceptualize downtown business districts as “firms,” thus allowing the identification of resources that lead to successful downtowns.

Purpose – To provide a general theory for how the ancient Mesoamerican economy functioned.

Design/methods/approach – First the chapter describes formally the sectors or operations of the economy: production, consumption, labor, specialization, exchange and prices, savings and investment, credit, quasi-money, markets, and dynamics. Then it relates this economy to its Mesoamerican cultural context.

Findings – Much but not all of this economy, with its great volume of transactions, worked according to market principles, without coinage or state-fiat money yet not barter. The theory has testable implications. Periods of growth and decline in preindustrial urban societies could have been due to economic forces.

Research limitations/implications – The presentation is verbal, not mathematical. Precolumbian economic documents hardly exist; advances in this line of research will have to come from archaeology (in part informed by earliest contact-era history).

Social implications – Extending theories of money and markets to include preindustrial urban societies should deepen and enrich economic thinking generally.

Originality/value of chapter – The first nonsubstantivist model of the Mesoamerican economy; insights on specialization and competition when firms are households; how high volumes of exchange work with commodity monies.

The purpose of this paper is to offer clarity on a central concept introduced in Porter’s The Competitive Advantage of Nations, i.e. the cluster. The authors situate the concept introduced by Porter (1990) relative to two of its antecedents, the industrial district and industrial complex. Placing the cluster in a historical context permits consideration of the extent to which it, as a concept for analysis, may be differentiated from other geography-based approaches to economic phenomena. In this way, this paper examines the added value of the cluster concept derived from economic factors.

The paper provides a detailed literature review tracing the evolution of theories of location and agglomeration into which Porter’s cluster fits. The evolution of Porter’s own conceptualisation of the cluster and how this relates to theoretical clarity surrounding the concept is explored. Comparative analysis of theories of location, agglomeration and clustering is provided to identify similarities and differences across the approaches and identify the added value of the cluster concept in relation to other approaches.

Clustering represents a process associated with spatial organisational form which may offer advantages in efficiency, effectiveness and flexibility. Cluster benefits can be appreciated through the lens of Young’s (1928) identified sources of increasing returns. A key aspect in clustering is revealed in terms of its role in enabling four sources of increasing returns. The authors outline how these sources of increasing returns are related to “soft” processes of networking, interaction and individual and collective learning. Porter’s Diamond is a self-reinforcing system which can permit increasing returns and reinforce such tendencies of economic activity within agglomerations.

Added value from Porter’s cluster concept is identified in the context of both its locational anchoring and in terms of its potential for understanding the role of exploitation of increasing returns for development. This points to the importance of focusing on clustering as a process rather than on cluster within typologies of organisational form. This implies that the nature of relationships (and how they change) within and across markets, institutions and actors lies at the heart of clustering because of their roles in knowledge-generation, including innovation, knowledge sharing and upgrading.

This chapter aims to familiarize the reader with some of the important aspects of tourism geography in the German-speaking countries. It starts with a primarily historical-genetic perspective on tourism development and the theoretical traditions associated with them. The second section describes the structure of the discipline, with a focus on the institutionalization of the field in the universities including their research specialization. The chapter maintains that tourism geography plays a marginal role compared with other subdisciplines of geography, though this is reflected primarily in its institutionalization and less so in the research undertaken. The last section deals with the current challenges and future prospects in German-speaking geographies of tourism from a problem-centered perspective.
