Producer Services, Economic Geography, and Services Tradability

We investigate how the incorporation of producer services linkages affects the outcome of an economic geography model. We specify the production of manufactures such that a variety of producer services is needed to transform tradable unfinished goods into final consumption goods. We find that service linkages promote the concentration of economic activity in a single region, but whether full concentration is achieved depends on the costs and mode of services trade. Applying the model to a multiregion world shows that incorporating producer services may also give rise to regions that specialize in different economic activities.     

Black and White Literature,Grey Scholars

Two key reasons are most often cited for the low impact of grey literature sources in archaeology, difficulties with access and lack of peer review. Seymour (this volume) has examined the constitution of grey literature and discussed themes surrounding accessibility. Although peer review is an important topic that deserves careful consideration, for the present discussion it is sufficient to state that the vast bulk of archaeology’s grey literature, the reports resulting from Cultural Resource Management (CRM) projects, receives several levels of careful, often expert review before acceptance as the basis for development project approvals. Without minimizing the importance of access to the grey literature or disparaging important efforts to improve it, then, this paper focuses on a separate issue, the discourse surrounding grey literature in archaeology and the hegemony it supports. I offer a manifesto, rather than a scientifically dispassionate account, because the current situation requires change, not study.

Grey Literature,Academic Engagement,and Preservation by Understanding

Archaeological practice in the UK produces considerable amounts of reportage that is never intended for formal publication. This grey literature forms a resource which has, historically, been poorly used by academic archaeologists, and problems of access have been blamed for this. This paper argues that this problem does not lie with accessing the resource, but has been of awareness, attitude, and understanding. Structures are now in place which can allow the comprehensive interpretation and reinterpretation of fieldwork results by any archaeologists who choose to do so.     

Rubber and Carbon: Opportunity Costs,Incentives and Ecosystem Services in Acre,Brazil

The concept of ‘opportunity costs’ has been important in theoretical discussions of Payments for Ecosystem Services (PES). It focuses attention on economic trade-offs of individual landholders and can make providing ecosystem services, such as tropical forest carbon sequestration, appear to be a cost-effective way to reduce near-term carbon emissions. Yet in practice, the concept may be less useful. This article examines how a programme in the Amazonian state of Acre, Brazil, has moved away from the concept of opportunity costs, challenging its theoretical importance. Instead of payments, the Acre programme offers ‘incentives’ intended to make rural people produce more whilst deforesting less. It resonates with the neoliberal commodification of carbon and the dominant valorization of intensive agriculture. Yet it also enlists lessons from Acre's history of rubber production and its rubber tapper-led social movement, namely that the living forest can be monetarily valuable and that its use can facilitate its protection. This article shows how local history and culture can be used to reshape PES.     

Rural Accessibility of General Practitioners: the Case of Bruce and Grey Counties, ONTARIO, 1901–1981

Using data from censuses and medical directories and various measures of availability and accessibility, trends in patterns of access at the two-county and township level are considered against the backdrop of substantial changes in the spatial organization of rural areas and in systems of health care delivery. The results suggest that the negative impact of the decline in, and centralization of, general practitioner services available to the dispersed population of the region between 1901 and 1981 was only partly offset by increases in mobility. Individual rural localities fared differently, largely dependent on their location relative to the central place network.
A l'aide de donnkes provenant des recensements, des annuaires medicaux et de d'autres mesures de la disponibilite et de l'accessibilite, nous en venons h considerer, au niveau des deux comtts et des cantons, les types d'accts, tout en gardant en mtmoire les changements importants dans l'organisation spatiale des regions rurales et dans la dispensation des services de santt. Les resultats de notre etude impliquent que I'augmentation de la mobilite a tres peu compenst pour les effets negatifs decline et de la centralisation des services de medecine generale dispensts aux habitants eparpilles de la region entre 1901 et 1981. I1 est evident que le bien-Ctre de chacune des localids rurales a varie grandement et dependait de leur emplacement par rapport au rtseau central.     

Managing,Valuing, and Protecting Heritage Resources in the Twenty-First Century: Peatland Archaeology,the Ecosystem Services Framework,and the Kyoto Protocol

Abstract

This paper argues that the development of the Ecosystem Services framework, which has recently emerged as an internationally recognized framework for valuing ‘the ‘natural capital’ of ecosystems, presents a number of opportunities for heritage management and the archaeological record, arguing that the inclusion of archaeological and palaeoenvironmental ‘value’ within this framework presents an opportunity to incorporate heritage alongside a range of other critical ‘services’. It presents a short case study focusing on the problems facing the preservation of peatland archaeological sites and deposits in situ alongside developments within peatland conservation and restoration initiatives partly driven by the ability of healthy, functioning peatlands to sequester carbon and hence mitigate climate change. It is argued that this drive towards peatland re-wetting may bring both positive benefits and opportunities for heritage management but also presents a number of practical issues, which now require active engagement from the archaeological community.     

Geography, Spatial Data Analysis, and Geostatistics: An Overview

Geostatistics is a distinctive methodology within the field of spatial statistics. In the past, it has been linked to particular problems (e.g., spatial interpolation by kriging) and types of spatial data (attributes defined on continuous space). It has been used more by physical than human geographers because of the nature of their types of data. The approach taken by geostatisticians has several features that distinguish it from the methods typically used by human geographers for analyzing spatial variation associated with regional data, and we discuss these. Geostatisticians attach much importance to estimating and modeling the variogram to explore and analyze spatial variation because of the insight it provides. This article identifies the benefits of geostatistics, reviews its uses, and examines some of the recent developments that make it valuable for the analysis of data on areal supports across a wide range of problems.     

Producer Services,Transaction Activities,and Cities: Rethinking Occupational Categories in Economic Geography

Applying insights from 'new institutional economics' to classify economic activities or occupations avoids some problems for which conventional classifications of services and particularly producer services have long been criticized. In institutionalist thinking the mixture of organizational forms such as market, hierarchy or network in an economy is mainly determined by transaction costs, which can in turn be correlated to specific 'transaction activities'. Typical transaction activities can be identified in markets and in other institutional arrangements, allowing the classification of real economic activities, occupations or firms as transactional or not. Many other commonly applied labels like informational related activities appear comparatively imprecise. This categorization and differentiation sheds new light on discussions about spatial development, from the world city debate to claims about the presumed role of high-tech occupations in metropolitan areas. It is argued that transactional occupations, especially those requiring higher qualifications, can be expected to be highly concentrated in larger agglomerations. In contrast, many non-transactional occupations though requiring high qualifications and usually also regarded as basic for metropolitan economies, like parts of R&D, are not necessarily concentrated there.

Troubled Encounters: Payments for Ecosystem Services in Chiapas,Mexico

Payments for Ecosystem Services (PES) is a well-established conservation policy approach worldwide. Where forests are owned and managed by rural and indigenous communities, PES initiatives often aim to incentivize the joint adoption of forest protection and sustainable management practices. However, not all communities might have the will or capacity to maintain such practices over the long term. This article examines a PES programme in a rural community of Chiapas, Mexico. It shows that while a majority of the community's landowners have engaged in PES through two distinct working groups, a large share of the community forests remain outside the PES programme, and many landowners resist the extension of PES rules to non-targeted forests. The authors argue that this incipient form of fragmented collective action on forest management results from challenged leaderships, and from PES accommodating a history of increasing individuation of the commons. This accommodation, however, has ignited social conflict, reified tenure inequalities, and failed to strengthen local institutions to enable them to legitimately deal with the contested interests that underpin the fate of community forests. This article shows the limits of PES when parachuted into a context of uneven land tenure, weak collective action and contested leaderships.
