Vertikale Integrationsstrukturen kommunaler Verkehrsunternehmen : eine transaktionskostentheoretische Evaluation

Der Markt für öffentlichen Personennahverkehr (ÖPNV) wird liberalisiert, in die gewachsenen Monopolstrukturen werden Marktmechanismen implementiert. Ziel der neuen ordnungspolitischen Rahmenbedingungen ist die Steigerung der Effizienz des defizitären Verkehrsbereichs, der von kommunalen Verkehrsunternehmen dominiert wird. Diese erbringen als Quasi-Monopolisten traditionell die Verkehrsdurchführung, regelmäßig anfallende Defizite werden von der öffentlichen Hand ausgeglichen. Bedingt durch ihre Leistungsstrukturen sind kommunale Verkehrsunternehmen in einem Wettbewerbsmarkt kaum konkurrenzfähig. Charakteristisch für diesen Unternehmenstyp ist der hohe Grad an vertikal integrierten Wertschöpfungsstufen. Im Gegensatz zu anderen Branchen erbringen kommunale Verkehrsunternehmen die wesentlichen Teile der gesamten ÖPNV-Wertschöpfungskette innerhalb der eigenen Unternehmensgrenzen. An dem hohen vertikalen Integrationsgrad setzt die Untersuchung an. Mit dem von Williamson entwickelten Instrumentarium der Transaktionskostentheorie werden die Leistungsbereiche einer transaktionskostentheoretischen Bewertung unterzogen. Als Alternativen zum institutionellen Arrangement der vertikalen Integration – das als Hierarchie bezeichnet wird – stehen die Arrangements Kooperation und Markt zur Verfügung. Die Bewertung zeigt, welche Leistungsbereiche unter transaktionskostentheoretischen Gesichtspunkten hierarchisch institutionalisiert werden sollten und welche alternativ erbracht werden können. Aus den Ergebnissen werden Strategieempfehlungen abgeleitet, die als Arbeitshypothesen einer anschließenden empirischen Überprüfung unterzogen werden. Die befragten ÖPNV-Experten bewerten somit die Marktfähigkeit der Strategieempfehlungen. Die Untersuchungsergebnisse werden für die Erarbeitung eines alternativen Koordinierungsarrangements für kommunale Verkehrsunternehmen herangezogen. Das Modell basiert auf der Grundlage Strategischer Netzwerke. Kommunale Verkehrsunternehmen nehmen in dem Modell die Rolle des Nukleus ein, der eine Vielzahl von Netzwerkpartnern steuert und für die Erbringung der ÖPNV-Leistungen mit diesen kooperiert.

Continuation and discontinuation of local institution in community based natural resource management

Currently the push toward frontier areas, which until twenty years ago were still largely untouched by commercial agriculture, is taking place on a massive scale. This push is being driven not the least by global economic developments, such as the price increase of agriculture commodities like coffee and cocoa. In most cases the indigenous communities become trapped between the state monopoly in natural resource management and the competition for resources by external actors. In this processes the indigenous communities start to lose their access to resources. Another victim in this process is the environment where the natural resources are imbedded. International and national organizations working to conserve environment have became conscious of the important role that indigenous people could fulfill as partners in this endeavour. This partnership in struggle has produced a new discourse on the relationship between indigenous people and their environment. As a further consequence, programs were set up to develop what became known as Community Based Natural Resource Management (CBNRM) with its numerous variations. Based on a case study in a village on the eastern border of the Lore Lindu National Park in Central Sulawesi, this study questioned the basic assumption behind the concept of Community Based Natural Resource Management (CBNRM). Namely the assumption that communities living at the margin of forest are socially and culturally homogenous, still more or less egalitarian, and basically living in harmony with their natural environment. This study was inspired by the persistent critique – although still a minority – on the basic assumption the CBNRM from academicians and practitioners working through the Entitlement perspective. Another inspiration was the mounting critique toward the participatory approach. In its effort the study explore further the usefulness of certain approaches. One of the approach much relied on in this study was the local history of the community studied, through exerting oral and local written documents on local history, legends and local stories. These sources proofed quite capable in bringing the local history into the light. Another was the actor oriented approach, which later came to be supported by the concept of Social Pool Resources. The latter concept proofed to be useful as analytical instrument to integrate social institutions and the common pool resources, as a field of action for the different actors as human agencies.

Difference and equality: A critical theorist analysis of post-modern philosophy

The following paper is a critical theorist analysis of post-structuralist philosophy. It examines the omission of an economic critique in post-structuralism and describes this omission as the result of a particular flaw in Nietzsche's epistemological work, an error which has persisted all the way down through deconstruction, post-colonialism, and cultural studies. The paper seeks to reintroduce an economic critique of capitalism back into the social critique of post-structuralism, with the promise that the combination of the two will prove stronger than either critical theory or post-structuralism alone. To achieve this it reinterprets Marx' concept of metabolism as a critical economic category that mirrors post-structuralism's concept of differance.

The Pursuit of Alternatives

Stories of peoples’ struggles across the globe are testaments to their determination to resist exploitation and injustice, and to imagine and construct their own narratives of economic and political difference. These stories of emancipatory moments demonstrate that something radically different in terms of dominant socio-economic relations and mental conceptions of the world may arise out of and beyond capitalism. The Pursuit of Alternatives: Stories of Peoples’ Economic and Political Struggles Around the World presents a fresh and new perspective on how the ‘process of becoming’ alternatives might take place based on peoples’ lived experiences. The chapters here, by labour activists and academics, explore how various forms of peoples’ economic and political initiatives and struggles in six countries – Brazil, Canada, Colombia, Nigeria, the Philippines, and South Korea – might become ‘actually existing’ spaces and moments for the development of critical consciousness and transformative capacities which are both central in challenging the dominant social, economic and political relations. The stories in this book bring to light today’s language of peoples’ struggles; what inspires people to create their own emancipatory moments and spaces for transformative self-change. While this book does not aim to propose an alternative to capitalism per se, it makes a stimulating contribution to the continuing debate on what alternatives to capitalist relations and arrangements might look like by grounding these alternatives in the everyday lives and struggles of workers, women, aboriginal peoples, the unemployed, and the poor.

How do domestic policies affect the integration of Ethiopian fertiliser markets with world markets?

Frequent shifts in policy on fertiliser markets have occurred in Ethiopia with the aim of facilitating both physical and economic access of farmers to fertiliser. The last shift was the introduction of a monopoly on each stage of the supply chain in 2008. Furthermore, government control of prices and margins as well as stockholding programmes are also present on the markets. This paper evaluates the effect of these policies on the integration of domestic with world markets of fertiliser, using cointegration methods. Time series data of diammonium phosphate (DAP) and urea prices on world, import and retail markets between 1971 and 2012 are used. The findings show high transmission of price signals from world markets to import prices for both DAP and urea. However, between import and retail prices there is no evidence of cointegration for urea, while for DAP full price transmission is concluded. In the retail market, domestic transaction costs associated with storing large volumes of fertiliser act as a buffer between import and retail prices, especially for urea. Therefore, economic benefits could be achieved by reducing the size of stocks and revising the demand estimation process.
