On the aubin-like characterization of competitive equilibria in infinite dimensional economies

For an exchange economy with finitely many agents and a commodity space which is infinite dimensional, it is proved that competitive equilibria are the same as allocations belonging to the fuzzy core of the economy. The latter is further characterized as a subset of the ordinary core of a suitably associated continuum economy.

Riassunto Per un'economia di puro scambio con un numero finito di agenti e uno spazio dei beni di dimensione non necessariamente finita, si prova che gli equilibri Walrasiani possono essere caratterizzati come allocazioni che appartengono al nucleo fuzzy dell'economia. Inoltre, queste ultime allocazioni sono in corrispondenza biunivoca con allocazioni di tipo semplice che si trovano nel nucleo ordinario di un'opportuna economia che ha [0,1] come spazio rappresentativo dello spazio degli agenti.

     

Resources and capabilities driving competitive advantage in export markets: guidelines for industrial exporters

In the context of the quest for the factors that determine competitive advantage, this study adopts a resource-based view and applies it to industrial goods' manufacturers engaged in exporting activities. The notion of organizational process is used as a filtering mechanism for the development of a classificatory scheme for firms' sources of competitive advantage in export markets. Different combinations of export-related resources and capabilities are identified as drivers of cost, service, and product advantage. Nonetheless, the capability to build enduring relationships with customers emerges as essential in achieving all three types of export competitive advantage. The findings of this inquiry have important implications for business practitioners in export manufacturing firms of industrial products. Limitations of the study are considered, and future research directions are identified.     

Tourism in the Great Limpopo Transfrontier Park

The Great Limpopo Transfrontier Park (GLTP) is a transboundary protected area that straddles the borders of Mozambique, South Africa and Zimbabwe. The park's development was partly motivated by the ecological objective of re-establishing traditional migratory wildlife routes once fences between the three countries are dismantled. Besides biodiversity conservation benefits, the park may also provide a basis to generate revenue for conservation and local economic development through tourism. This paper describes current state and private sector tourism within the GLTP and planning initiatives that may promote responsible tourism, and describes the achievements by community-based tourism enterprises and public–private partnerships in generating economic, social and environmental benefits. The livelihoods of people living in the park are outlined in relation to government policies on land redistribution, resettlement and options for the future, and progress in biodiversity conservation and responsible nature-based tourism development within the GLTP over the past five years is evaluated.     

The Asymmetric Effects of Monetary Policy

Abstract.  The paper deals with the asymmetric effects on output of tight and easy monetary policy: the output reduction following a negative monetary policy shock appears bigger than the expansion induced by similar sized positive shock. The paper first reviews historical evidence of asymmetry, focusing on the United States, Japan and Italy. This is followed by a review of the econometric literature on monetary policy asymmetry and consideration of the theoretical reasons that can explain this asymmetry.     

Sweden: A member of the European Union but without the Euro

The integration of the EU-member countries continues. An important step of this process was the introduction of the common currency, the Euro coins and bank notes in year 2002. During a time of incidents and events last year, Swedes made up their minds and declined the Euro favouring the Swedish krona in the referendum on 14 September 2003. This is a story about a small EU-member state that still needs time to integrate.
