The dispute over Canadian exports of softwood lumber products to the United States (US) has lasted since 1982 and, so far, has gone through four episodes of litigation. In Lumber IV, the US International Trade Commission (ITC) determined that the US softwood lumber industry was threatened with material injury by reason of dumped and subsidized lumber from Canada. Under the North American Free Trade Agreement (NAFTA), a binational panel concluded, however, that there was no such evidence and directed the ITC to reverse its finding. In its resort to the Extraordinary Challenge Procedure, the US alleged that the injury panel had misapplied the US standard of review. In fact, allegations of improper NAFTA panel review were used by the US in order to justify its non-compliance with adverse binding decisions.  相似文献

During the late medieval period, Bruges acted as the prime hub of international trade in north-western Europe, with the town of Sluys as its outport. Trade along the Zwin, the waterway connecting the city to the sea, was subject to a series of tolls and a set of stringent and comprehensive staple restrictions, stipulating that all goods imported had to be sold on the Bruges market. The concentration of commercial activities which resulted from these rules allowed merchants with the necessary capital to trade more cheaply than elsewhere. For those with more modest means and ambitions, the trip along tollbooths to the heavily regulated and institutionalised staple market only jeopardised the profitability of their endeavours. Throughout the fifteenth century, local traders, international shipping crews, commercial staff and professional smugglers cut transaction costs by evading the restrictions of the staple and commercial taxation in Sluys. This article discusses the size of this informal market on the margins of Bruges' jurisdiction, analyses the backgrounds and motivations of its visitors and reconstructs the strategies they used to evade punishment.  相似文献

ABSTRACT

News, print and the associated communications were not just a booming business in the early modern period, but are – research-wise – a “hot topic” at this moment as well. The seven volumes discussed are syntheses of many years of research. The books show overlap due to geography and events, and their stress on news bearing media of various sorts, all within the seventeenth century. Each of the volumes is written by an expert on either the Baltic Sea, Germany, or the Dutch Republic. The foci vary from the exchange of information to the printing of newspapers and books, to the use of advertisements.  相似文献

Viking age honestones from four large sites in northern Europe have been made from two different types of quartz-muscovite schist: one dark grey, very fine-grained schist, and a light grey, fine-grained schist. In order to determine the provenance of these schist hones, KAr ages have been determined on 16 selected representative hones. The dark grey schist hones yield Caledonian ages of 403–446 Ma. and consideration of petrographic evidence leads to the conclusion that the hones were quarried in the Caledonian area (presumably) of Western Norway. The light grey schist hones are Precambrian, with KAr ages of 931–946 Ma, and are presumed to originate from Telemark, South Norway. The amount and homogeneity of these honestone groups from different parts of the Viking world indicates the existence of large quarries, and demonstrates that production and trade were more wide-ranging than had hitherto been assumed.  相似文献

ABSTRACT

The failure mechanism of corners in masonry buildings has frequently been observed in seismic scenarios, but only a few works and no experimental investigations devoted to it are available in the literature. In this aritcle, the experimental behavior of a simple masonry corner is first analyzed, by simulating the seismic horizontal actions through a progressive tilting of the supporting base. Then, the conditions of the onset of two possible failure modes are analytically formulated: they are the rocking-sliding and the horizontal flexure mechanism. A three-dimensional macro-block model with frictional joints is used to analyze these mechanisms, while the crack patterns and the load factors are derived through the kinematic approach of the limit analysis. The evaluation of the in-plane frictional resistances involved by the rocking-sliding mechanism is performed by applying a reliable criterion previously proposed, while for the torsion strength involved in the horizontal flexure mechanism, simplified yield conditions are adopted and a possible criterion is also introduced to take into account the actual reduction of the contact surfaces. Last, the experimental findings are compared and critically interpreted in light of the analytical results and the influence of the main parameters on the prevailing mechanism is highlighted.  相似文献

ABSTRACT

This paper investigates Bulgaria’s trade strategy towards the European Economic Community (EEC) in the 1970s: a decade of intensified economic exchange between East and West thanks to détente and, simultaneously, of growing trade barriers due to the consolidation of the EEC’s Common Market. The successes and failures of Bulgaria’s endeavours are discussed through a study of economic cooperation with Denmark before and after its accession to the EEC in 1973. The main argument is that while Bulgarian economic policy focused on the rising regulatory impediments to trade with EEC members, it neglected the structural deficiencies of Bulgarian export production. Thereby, Bulgarian state officials strove to resolve foreign trade problems through diplomatic negotiations over customs regulations instead of advancing domestic economic reforms . This argument is supported by analysis of intergovernmental economic negotiations and trade deals between Bulgaria and Denmark during the 1970s. It highlights the different ways in which Bulgarian trade envoys in Copenhagen and top officials at home evaluated recurrent problems in accessing the Danish market and formulated solutions for these problems. Thus, instead of tackling internal structural problems, the blueprints for Bulgaria’s foreign trade focused on external foes, namely trade discrimination against socialist countries.  相似文献

This article examines Canada’s trade policy in light of efforts by the Harper government to respond to increasing global competition through the Global Markets Action Plan (2013). Through an analysis of three initiatives, the Canada–Korea Free Trade Agreement (CKFTA), the Canada–European Union Comprehensive Economic Trade Agreement (CETA), and the Trans–Pacific Partnership (TPP), it becomes clear that Canada’s current strategy has only gone part of the way to enact policies that will be most beneficial to its economy. This article shows that Canada’s Global Markets Action Plan, though ambitious, does not correctly prioritize Canada’s interests: it gives too little attention to improving Canada’s strongest trading relationship with its immediate neighbors in North America; it does not comprehensively address the changing nature of trade (which is now focused on trade in value-added products); and finally, its almost singular focus on market access and increasing exports directs attention away from the type of liberalization that would be most beneficial to Canadians, which is opening up the market for imports and dismantling Canada’s supply management system.  相似文献

ABSTRACT

Canada’s dairy farmers have spent the last 40 years fighting to preserve their supply management system despite increases in the desire to liberalize trade through the expansion of regional free trade agreements and the targeting of agriculture in recent rounds of the General Agreement on Tariffs and Trade (GATT). How has Canada’s supply management system resisted trade liberalization thus far? Moreover, what strategies have Canadian dairy farmers used to lobby the government to preserve this system? The answer to these questions lay within the intersection of culture and economics. Canadian dairy farmers have been successful in framing Canadian dairy as a distinctly Canadian cultural commodity, and therefore framing supply management as the economic tool needed to defend this cultural commodity. In exploring this topic, this article will touch on Canada’s history of preserving cultural institutions, as well as the historical importance of Canada’s supply management system.  相似文献

Is world‐systems analysis of any relevance to present‐day economic flows? By using methods in line with the world‐system and dependence theories, we show that economic flows – trade and foreign direct investment – still deeply separate core and peripheries. On the one hand, through the analysis of the trade by products, we show that core countries hold on to a higher position in the international division of labour. On the other hand, by using network method, we highlight that core countries are still characterized by the intensity of their reciprocal relations while peripheral countries have few economic relations with a limited number of core countries. Moreover, the article demonstrates that this core–periphery division of the world has not lost its pertinence; it is as relevant as at the end of the sixties. In the current era of globalization, economic flows are still deeply structured by basic power relations between core and peripheries. However, the article also develops a theoretical framework to understand dynamics of the world‐system and insists on the emergence of Eastern Asia as a new core area, notably by showing the rising position of some East Asian countries in the international division of labour. We conclude by underlying the necessity to integrate world‐system and global network theoretical frameworks.  相似文献

ABSTRACT

This article deals with the embargo imposed by the papacy and the Catholic lay powers on all trade and commerce with the Czech Hussites. It posits that this anti-Hussite embargo was simultaneously a means of economic warfare and an expression of the longer tradition of the papal embargo. Based on this twofold understanding, a set of sources is interrogated both from the perspectives of economic and cultural history. To this end a research methodology is employed that differentiates between the instrumental and symbolic dimensions of agency. This allows for a new, holistic view of the anti-Hussite embargo, both as an instrumental means of warfare and as a communicative process. The article thus contributes to political, economic and cultural history as much as to the history of everyday life in fifteenth-century Central Europe. Above all, however, it offers a transferable research methodology for the study of medieval embargoes in general.  相似文献
