Economic integration and the diversification of regional exports: evidence from the Canadian-U.S. Free Trade Agreement

We investigate the impact of Canada–U.S. trade integrationon the degree of export diversification of the Canadian regions.Trade integration is captured through the decrease of trade-weightedtariffs that were boosted by implementation of the Canadian–U.S.Free Trade Agreement. We found strong evidence to support integration'slong-run impact on the patterns of absolute exports diversification.Significantly, this new finding remains robust to the exclusionof the primary sectors and to the potential presence of unitroot in the data. Our results lead us to support a positivelong-run relationship between trade integration and export diversification.     

The Landes de Gascogne (southwest France): periglacial desert and cultural frontier during the Palaeolithic

During the last glacial period, a large part of the Aquitaine basin (southwest France) was a periglacial desert comprising coversands with low-relief dune fields surrounded by loess accumulations. OSL and radiocarbon dates show that the phase of maximum sand deposition coincides with Marine Isotope Stage (MIS) 2. Peats and gleyic palaeosoils intercalated within the sands at some sites indicate that vegetation cover was able to develop locally during short events, possibly D–O interstadials, due to raised groundwater levels in interdunal depressions. Few Palaeolithic sites have been discovered in the coversand area in contrast to the peripheral loess region. Systematic survey along a future highway corridor demonstrates that this paucity of sites is not the result of insufficient survey nor deep site burial, but rather reflects an archaeological reality. This strongly suggests that the sand area was not attractive for hunter–gatherer populations due to its reduced levels of water resources, and available vegetation and animal biomass. The distribution of cultural markers such as art items and projectile points also shows that the coversand area probably acted as a barrier separating two different cultural sub-areas, one in the Pyrenees and Cantabria, the other in the Périgord. As a consequence, the commonly accepted view that southwest France, as a whole, served as a refugia during the cold and arid phases of the Pleistocene should be replaced by a more complex one that reflects the fact that a large part of the territory was almost unoccupied and that human populations were concentrated along alluvial valleys.     

A new map of Qâni’ (Yemen)

Qâni’, the main seaport for the export of goods from South Arabia, was founded by the Hadramawt kingdom in the first century BC. A geomorphological survey and a general surface reconnaissance of Qâni’ have revealed a new image of the site. Originally a royal entrepôt in a fortress on an ancient island, separated from the mainland by a silted channel lined with a mangrove forest, Qâni’ gradually grew and spread around the beach fronting the mooring place of the trade ships that arrived by sea. Sacred spaces, cemeteries, dwellings and trade quarters appear to be well‐defined areas forming a real town within the limits imposed by the surrounding sea.     

Regional Perspectives on Dollarization in Canada

Abstract In this paper we investigate whether it is preferable for Canadian regions to individually adopt the U.S. dollar or to remain with the current currency arrangement. The empirical analysis focuses on the cross–correlations of various business cycle measures of Canadian regions, of Canada, and of the United States. The business cycle investigation is completed by the analysis of two other important criteria for optimum currency areas, industrial specialization and trade interdependence. Our results highlight a significant heterogeneity across Canadian provinces. In particular, it transpires that it could be economically advantageous for the central provinces of Ontario and Quebec and to a lesser extent British Columbia to adopt the U.S. dollar. In contrast, it is not as clear what the other regions should do, the final answer depending on the path the larger three provinces take.     

Knowledge maps as aids to knowledge management in spatial planning

This paper presents four ‘knowledge maps’ or ‘schemes’ which can be used as aids to knowledge management in spatial planning. The schemes relate to the four dimensions of knowledge, i.e. content, sources, application and methods. The schemes are based upon theoretical considerations as well as on practical experience with knowledge management for planning projects, some examples of which are given. They are, furthermore, tested in various ways as to their usefulness. Their primary purpose is, in fact, to make aspects of knowledge management which in practice are often applied in an intuitive manner more explicit, and thus to enhance their reliability.
