PRODUCT DIFFERENTIATION,PRICING POLICY AND EQUILIBRIUM*

ABSTRACT. This paper studies the price-location equilibrium of duopolists supplying differentiated goods and competing in a spatial market with elastic demand. We show that a price-location equilibrium exists under all three pricing policies traditionally considered by the literature: f.o.b. mill, uniform delivered, and spatially discriminatory pricing. We also show that firms always cluster at the market center. The second part of the paper studies the endogenous choice of pricing policy. A surprising feature of the resulting equilibrium is asymmetry. The greater the extent to which the goods are substitutes, the more likely is it that one firm will choose f.o.b. pricing and the other price discrimination. Finally, the welfare consequences of the analysis show some interesting trade-offs.     

Best practice? Geography, learning and the institutional limits to strong convergence

According to many, we live in an age in which convergence betweenformerly distinct national ‘models’ is taking place.Central to this process is a learning dynamic in which bestpractices originating from within one model—Japan in the1980s, United States in the 1990s—are supposedly adoptedby firms elsewhere. This paper addresses two key questions concerningthis process. First, what are the actual mechanisms or processesthrough which this learning-driven convergence might occur?Second, what role do institutions play in shaping, influencing,or constraining firms' choice of practices and their abilityto ‘learn’? The paper examines eight specific channelsof convergence representing a continuum of opportunities forlearning-through-interacting. It then assesses critically arange of competing arguments about the role of institutionalinfluences at three different scales: the region, the nation-state,and the firm. It concludes that while regional and firm-levelarguments, on their own, do not provide an adequate explanatoryframework for understanding how firms' practices are determined,national level theory needs to be made supple enough to accommodatea significant role for regional institutions and the agencyof the firm.     

Resources,Agency, Achievements: Reflections on the Measurement of Women's Empowerment

This paper begins from the understanding that women's empowerment is about the process by which those who have been denied the ability to make strategic life choices acquire such an ability. A wide gap separates this processual understanding of empowerment from the more instrumentalist forms of advocacy which have required the measurement and quantification of empowerment. The ability to exercise choice incorporates three inter-related dimensions: resources (defined broadly to include not only access, but also future claims, to both material and human and social resources); agency (including processes of decision making, as well as less measurable manifestations of agency such as negotiation, deception and manipulation); and achievements (well-being outcomes). A number of studies of women's empowerment are analysed to make some important methodological points about the measurement of empowerment. The paper argues that these three dimensions of choice are indivisible in determining the meaning of an indicator and hence its validity as a measure of empowerment. The notion of choice is further qualified by referring to the conditions of choice, its content and consequences. These qualifications represent an attempt to incorporate the structural parameters of individual choice in the analysis of women's empowerment.     

PRICE AND LOCATION CONJECTURES IN MEDIUM- AND LONG-RUN SPATIAL COMPETITION MODELS*

ABSTRACT. This paper examines medium-run and long-run equilibria in unbounded (circular) and bounded (linear) one-dimensional multifirm markets. A price-location adjustment model is outlined that dows simulation of the spatial equilibrium when these firms anticipate reactions from their nearest spatial rivals. Thus, the market equilibrium is derived from the interdependent but atomistic decisions of the competing firms and is not imposed by some outside observer or agency. Ail conjectures are exogenous; the three well-known price conjectures (Greenhut-Ohta, Hotelling-Smithies, and Losch) are highlighted; and the relevant comparative statics are provided.     

Children's daily travel to school in Johannesburg-Soweto,South Africa: geography and school choice in the Birth to Twenty cohort study

This paper has two aims: to explore approaches to the measurement of children's daily travel to school in a context of limited geospatial data availability and to provide data regarding school choice and distance travelled to school in Soweto-Johannesburg, South Africa. The paper makes use of data from the Birth to Twenty cohort study (n?=?1428) to explore three different approaches to estimating school choice and travel to school. First, straight-line distance between home and school is calculated. Second, census geography is used to determine whether a child's home and school fall in the same area. Third, distance data are used to determine whether a child attends the nearest school. Each of these approaches highlights a different aspect of mobility, and all provide valuable data. Overall, primary-school-aged children in Soweto-Johannesburg are shown to be travelling substantial distances to school on a daily basis. Over a third travel more than 3 km one way to school, 60% attend schools outside of the suburb in which they live, and only 18% attend their nearest school. These data provide evidence for high levels of school choice in Johannesburg-Soweto, and that families and children are making substantial investments in pursuit of high-quality educational opportunities. Additionally, these data suggest that two patterns of school choice are evident: one pattern involving travel of substantial distances and requiring a higher level of financial investment and a second pattern involving choice between more local schools, requiring less travel and a more limited financial investment.     

Land-Use Allocation in the Absence of Complete Market Values

This paper describes a method of land-allocation that can be used byplanners and other land managers in the face of market failure. The method integrates theland-allocation approach used in geographic information systems with that used in a generalizedassignment problem. Suitability scores, instead of market prices, are used in assigning competingland uses to individual parcels (pixels) of land. The method is illustrated using a hypotheticalexample involving three competing land uses within a region.     

Contested subterranean territory: Gold mining and competing claims to Indonesia’s underground

Worldwide, subsurface resources are typically the domain of the state. Their cataloguing and government-permitted extraction comprise key elements of state territorialization of the subterranean. However, like processes of territorialization aboveground, state control of the underground is always incomplete and subject to competing uses of space and resources. One of the clearest examples of this contestation is unlicensed small-scale mining. In this article, I examine a case of gold mining conflict in the Pongkor region of West Java, Indonesia. There, state-corporate and small-scale mining compete over the same gold reserves, directly confronting each other both above and below ground. Drawing on twelve months of ethnographic research, I analyze three ways that state-corporate and small-scale mining vie for control of these subterranean territories: regulating movement between the surface and subsurface, managing underground volumes, and deploying competing geological knowledges. I argue that verticality, volume, and the material and discursive features of the underground do not merely set the conditions for this conflict, but are also dynamics utilized to territorialize underground space. I call for further scholarly inquiry into contemporary, ongoing processes of subterranean territorial contestation and reproduction.     

Growth and albitization of K‐feldspar in crystalline rocks in the shallow crust: a tracer for fluid circulation during exhumation?

A general feature of medium‐ to coarse‐grained, sheet‐silicate bearing, quartzo‐feldspathic rocks of either metamorphic or igneous affinity is the retrograde development of lenses of pure K‐feldspar at the grain boundaries between sheet silicate (0 0 1) faces and original feldspar grains. The growth of these lenses acts to displace and deform the sheet silicate grain by a force of crystallization, although the substrate feldspar and adjacent quartz are not deformed. Subsequent to the growth of the lenses they are replaced to variable degrees by pure albite, which grows into the lens from the substrate feldspar behind an irregular replacement front. The composition and texture of both K‐feldspar and replacive albite suggest a strong affinity with authigenic feldspars, although it is considered likely that the K‐feldspar of the lenses is derived from low‐temperature biotite‐breakdown reactions. A model is proposed whereby the lenses grow into open pores at dilatant sites in response to infiltration of aqueous fluids as the crystalline rocks are exhumed under brittle conditions. Continued circulation of infiltrating fluids in a temperature gradient results in the replacement of K‐feldspar by albite via an alkali exchange process. The lenses point to a significant grain‐scale permeability in crystalline rock at shallow levels in the crust.     

MAKING COLOURLESS GLASS IN THE ROMAN PERIOD*

This paper discusses the compositional analysis of Roman colourless glass from three sites in Britain. The findings suggest that two broad compositional groups can be identified on the basis of the choice of the initial raw materials selected for glass production, in particular the sand. The largest of these groups is inherently different from the naturally coloured, blue–green glasses of the same period, while the other group is compositionally similar. Further subgroups are apparent on the basis of the decolorizers used. These glass groups are explored in the light of the current theories concerning the organization of glass production in the Roman world.     

Neoliberal Reason and Its Forms: De‐Politicisation Through Economisation

This paper offers a historically contextualised intellectual history of the entangled development of three competing post‐war economic approaches, viz the Austrian, Chicago and post‐Walrasian schools, as three forms of neoliberalism. Taking our cue from Foucault's reading of neoliberalism as a mode of governmentality under which the social is organised through “economic incentives”, we engage with the recent discussions of neoliberal theory on three accounts: neoliberalism is read as an epistemic horizon including not only “pro‐” but also “post‐market” positions articulated by post‐Walrasian economists who claim that market failures necessitate the design of “incentive‐compatible” remedial mechanisms; the Austrian tradition is distinguished from the Chicago‐style pro‐marketism; and the implications of the differences among the three approaches on economic as well as socio‐political life are discussed. The paper maintains that all three approaches promote the de‐politicisation of the social through its economisation albeit by way of different theories and policies. © 2013 The Author.

Housing Choice in a Regulated Market: A Nested Multinomial Logit Analysis

The paper integrates several important elements of the institutionalized and regulated nature of the housing market and analyzes the relationship between household type and housing choice in Vienna within a nested multinomial logit framework. In particular, the concept of household specific choice sets is used to account for institutional, informational and income-based constraints of the choice process. Government subsidies (such as housing and rent allowances, non-interest-bearing state loans) are explicitly taken into account in the definition of variables. Housing choice is considered in three stages: the choice of a dwelling unit given dwelling type and residential zone, the choice of a dwelling type given residential zone, and the marginal choice of a residential zone. The coefficients are derived by means of a sequential ML-procedure. The empirical results clearly indicate that demographic variables have significant impacts on housing choice behavior. Income as a single explanatory variable as well as its interacting with size measures and the quality of the house are found to be important criteria for dwelling unit choice, as housing cost variables for dwelling type choice behavior. The dwelling unit and dwelling type choice submodels fit reasonably well, whereas the residential zone model is less successful.     

Conflict and Complement: An Exploration of the Discourses Informing the Concept of the Socially Inclusive Museum in Contemporary Britain

This paper argues that there are a number of competing discourses informing debates about the idea of the ‘socially inclusive museum’ in Britain today. It identifies three major discourses present from the 19th century to the present day—the governmental, the representational, and the economic—and explores the relationships between them. It is proposed that recognition of the respective ideological and historical contexts of these different discourses will help us to understand some of the recent confusion and disagreement over the nature and merits of the ‘socially inclusive museum’. The article concludes by proposing some issues for future research.     

Drivers for Policy Agreement in Nascent Subsystems: An Application of the Advocacy Coalition Framework to Fracking Policy in Switzerland and the UK

The study of public policy deals with subsystems in which actors cooperate or compete to turn their beliefs into policy solutions. Yet, most studies concern mature subsystems in which the main actors and their allies and enemies can easily be identified. This paper tackles the challenge of studying nascent subsystems, in which actors have begun to engage in politics but are uncertain about other actors’ beliefs. Actors therefore find it relatively difficult to identify their allies and opponents. Focusing on the Advocacy Coalition Framework, we examine three main ways in which actors might agree to support the same policy design before they decide whether or not to form long‐term relationships within advocacy coalitions: they see the issue through the same lenses, they follow leaders, or they know each other from earlier cooperation. We use the case of fracking policy in Switzerland and the UK as a key example, in which actors have begun to agree with each other, but where final policy outputs were not yet defined, and long‐term relationships not yet observable. We find that, when dealing with new issues, actors strongly rely on former contacts rather than shared ideologies or leadership.

The Nation as a Community Born of War? Symbolic Strategies and Popular Reception of Public Statues in Late Nineteenth-Century Western European Capitals

The genesis and development of Western European nationalism is widely connected to the notion of the nation as emerged from war. This paper focuses on that cultural combination in terms of the symbols and programmatic rhetoric employed in commemorative rituals surrounding public statues—mainly in honour of military personnel—in late nineteenth-century Paris, London and Berlin. As the experience of a total war lay still ahead, the national heroes elevated on plinths besides existing war memorials were not intended to express personal mourning or to manage bereavement. They were erected as morally charged expressions of specific national ideals. Based on a sample of some twenty public statues in Paris, London and Berlin, this paper identifies three strategies of intentional manipulation: compensating for military defeat by alternative interpretive patterns in France, overwriting the competing claims of different conceptions of nationhood in Prussia-Germany, and legitimising the nation-state on an imperial scale in Britain. Comparison of these three cases substantiates the claim that there were three ‘special paths’ for legitimising the nation through war, each dependent on historical contingencies (such as the trauma of defeat or experiences of victory). In all three cases, however, the experience of war served as a means of justifying national claims to power while omitting all reference to the inner make-up of each nation. At the same time, adequate historical assessment of metropolitan public statuary requires that public reception as well as official symbolism and rhetoric be taken into account. Responses to the statues indicate that the widespread popular appeal of national war myths was far from automatically achieved. Instead of fostering cohesion, the reception of cult figures occasionally came up against political controversies that served as factors limiting national propaganda.     

‘What’s left of the flag’: the Confederate and Jacobite ‘lost cause’ myths,and the construction of mythic identities through conflict commemoration

The use of battlefields and associated conflict sites provide tantalising hooks upon which to hang tapestries of grand narratives relating to regional and national identities, often defined by what the identities are not. This paper examines the unlikely connection between Jacobite and Confederate romanticism, and how battlefields, conflict related sites, and symbolic material culture are mobilised through active commemoration by some heritage groups in support of a created, mythic identity of a ‘Southern Celt’. Furthermore, it examines the production of a mythic history that whitewashes and recasts the Confederacy, the reality of the Civil War, and the Confederate Flag, while at the same time minimising, hiding, or ignoring competing narratives.     

The Rising Agenda of Physician-Assisted Suicide: Explaining the Growth and Content of Morality Policy

Employing theories and methods of agenda-setting analysis, this article explains the rapid rise of physician-assisted suicide (PAS) on the national political agenda based on its status as a morality policy. PAS reached the mass agenda before the professional agenda, probably because PAS is an outgrowth of previous right-to-die policies and Dr. Jack Kevorkian's assisted suicides provided major focusing events. As in other morality policies, competing groups fight for the last word, but PAS has been blocked on most governmental agendas because its image and media tone has been mostly negative and public opinion is divided. Groups in a few generally liberal states have tried to enact policy through referenda when legislators failed to address the issue. We speculate that competing interest groups will become more active and that state courts will become a venue of choice in the future.     

Modeling Categorical Data with Chi Square Automatic Interaction Detection and Correspondence Analysis

For the past decade we have been concerned with the application of categorical data techniques to mobility and housing choice. In a previous issue of this journal we reviewed a number of these modeling techniques. We now extend that earlier work by introducing correspondence analysis as a geometric interpretative technique that fits in an intermediate position between CHAID and nested logit analysis. The method is illustrated on the same housing and tenure choice data as was used in the previous paper.     

Tacit coopetition: chimera or reality? Evidence from the Basque Country

Coopetition is a strategy by which firms benefit from both collaboration and competition. Collaboration among competitors allows these to obtain advantages such as the joint creation and diffusion of knowledge, the exploration of new market opportunities, the identification of long-term innovation projects related to potential market, product or process diversification, or the gaining of access to external sources while still competing in certain areas. This paper focuses on the concept of tacit coopetition, which is defined as cooperation activities between neighbouring competitors located in the same region. Our goal is to assess the influence of tacit coopetition on the cooperative pattern of firms, as an alternative to promoting innovative projects among competitors. The analysis is performed in the county of Durango, located in the Basque Country (Spain). In particular, we seek evidence of whether tacit coopetition is a reality that can be objectively observed in Durango, and therefore, has the potential for a wider generalization of the phenomenon, or is instead a conceptual rhetoric (i.e. chimera) that is only observable in specific cases. The paper provides three major results. First, it sets out to identify whether tacit coopetition is occurring in Durango. Second, it identifies the factors influencing it, and finally, assesses the impact of tacit coopetition on firm performance.
