A method of mapping the classic economic public good into a spatial realm is identified. Within the spatial equilibrium land use model an ideal government distributes a public good; sets mill rates, assesses land, and collects property taxes; and maintains a balanced budget. Equilibrium is brought about within the household sector by the unfolding of the land value schedule both over space and in response to the public sector. The household and public sectors are mutually within a steady state when there is no excess demand or supply of public good. The model is extended to elucidate Tiebout's hypothesis that government activity is reflected in land values. Also, a criterion for judging fairness of the spatial equilibrium assessment schedule is presented and applied.  相似文献

Educated citizens are often considered more likely to report corruption; this belief shapes anti-corruption campaigns. However, we know little about how other factors may interact with education’s impact on willingness to report corruption. This article examines data from a household survey undertaken in Papua New Guinea. We find considerable support for the notion that education encourages a greater willingness to report various types of corruption to officials. While our results indicate that this is especially the case when respondents believe that corruption would be addressed by the government, they also show that secondary and post-secondary levels of education can have a positive impact even among those who do not have much faith in reporting institutions. However, the results also suggest that academics and policy-makers should be sensitive to the way trust in the state impacts educated citizens’ willingness to report different kinds of corruption.  相似文献

In this paper, I examine the speculative dimensions of biodiesel production in Northeast Brazil under the National Program for the Production and Use of Biodiesel (PNPB), by focusing on the case of castor oil plant (Ricinus communis) in semi-arid Bahia, a promising flex crop that was said to generate social, environmental and economic benefits, especially for the historically marginalised Northeast peasantry. I argue that speculative practices over castor have relied on state policies and discourses as well as biophysical and biotechnological (im)materialities that are transforming agrarian relations in ways that compromise peasants’ control over their (re)productive systems while promoting the expansion of the agroindustrial frontier. By examining the everyday, performative and place-based character of speculative biodiesel practices and their uneven and contested socioenvironmental implications, this paper contributes to current political ecology debates on the nexus between agroenergy development, nature’s capitalist valuation and rural dispossession.  相似文献

This paper details the use of obsidian sourcing to reconstruct networks of interaction (or ‘communities of practice’) amongst populations of south-eastern Anatolia and the Near East in the context of ‘Neolithisation’ during the late 11th–early 10th millennia BC. EDXRF was used to elementally characterise 120 artefacts of Epi-Palaeolithic – Pre-Pottery Neolithic A date from Körtik Tepe in south-eastern Anatolia. Four eastern Anatolian sources are represented, mainly Bingöl A/B and Nemrut Da?, plus the first evidence for the use of Mu? obsidian. When the source data is integrated with the artefacts' techno-typological attributes it is possible to locate the assemblage within an Upper Tigris tradition (with some interesting local differences), which stands in stark contrast to contemporary practices in northern Mesopotamia and the Levant. These local and regional distinctions support recent views of the Neolithic being much more heterogeneous, with a ‘mosaic’ of community-specific/local traditions of subsistence practices, raw material choices and lithic technologies during the Younger Dryas–Early Holocene.  相似文献

Strontium isotope analysis on human remains from the Iron Age (4th/3rd century BC) cemeteries of Nebringen, Germany and Monte Bibele, Italy were carried out to investigate the role of residential changes during the period of the historic “Celtic migrations”. From an archaeological perspective, the location of the cemeteries in the Celtic core (Nebringen) and expansion area (Monte Bibele), and the distinctive development of their material culture, suggest that the buried populations had differing mobility rates. On the contrary, the strontium results indicate that only few individuals were mobile or non-local. There is, however, a difference in variation of strontium isotope ratios between the two studied cemeteries, presumably caused by differing geological conditions. In Nebringen changing use of cultivated land in a geologically heterogeneous environment most likely caused varying strontium isotope ratios even within the same jaw, while individual mobility over longer distances can also not be excluded. In Monte Bibele the range of strontium isotope ratios is narrow, and this may be explained by a community living in the same village and using the same agricultural resources. For various prehistoric time periods it has been suggested that some population groups were more mobile than others, for example because they had special social roles. In the two cemeteries studied here, males have slightly more often a non-local birthplace or moved during childhood. In contrast, females had isotope signatures which are more consistent with the local geological environment. Male mobility is, however, not correlated with burial as a warrior, and patrilocal residential patterns were not observed among females. Foreign and local items are found with isotopically local and non-local individuals and objects per se do not indicate descent. The motives for residential changes were, therefore, varied and not constrained to a specific area or population group. The presented dataset provides details on the way of life and land-use in the Celtic communities, for which information is otherwise absent.  相似文献

In their Institutions for the Earth (1993), Haas, Keohane and Levy argue that, at the international level, three fundamental conditions must be met for the effective management of environmental problems. They summarise these conditions as the three 'Cs'-the building of concern; the existence of a suitable contractual environment; and the growth of state capacity. We applied the Haas, Keohane and Levy (HKL) model to three case studies at the national level, in order to ascertain the extent to which the three Cs explained the emergence of successful institutional regimes. We found that two of the three variablesimprovements to the contractual environment and increases in state capacity-had considerable explanatory power. Concern was important in providing the motive force for change, but high levels of concern did not lead to effective institutional regimes unless the other two factors were present. We found a strong reciprocal relationship between state capacity and the contractual environment-the ability to monitor solutions and to generate policy-relevant 'trustable' information, was positively associated with improved negotiating structures and outcomes.  相似文献
