Before 1852 the English patent system operated at both a domestic and a global level, allowing inventors to extend its operation beyond England to the colonies, where it interacted in territories such as Jamaica with a colonial system of patents and grants. It therefore provides one of the few examples of a workable global patent system, and an important case study of the structures that supported the development and circulation of technology within the British Atlantic during the early stages of the industrial revolution. Providing a framework of ‘tiered’ rather than ‘parallel’ powers and jurisdictions, the imperial patent system was a flexible instrument that inventors could use strategically to promote transnational technological innovation, in which people, ideas, and skills moved back and forth between Britain and colonies such as Jamaica. Patenting, which was concentrated in wealthy plantation colonies that sought greater productivity, was therefore a key part of the economic development of empire.  相似文献

The prospect for electric vehicles as a climate change solution hinges on their ability to reduce gasoline consumption. But this depends on how many miles electric vehicles are driven and on how many miles would have otherwise been driven in gasoline-powered vehicles. Using newly-available U.S. nationally representative data, this paper finds that electric vehicles are driven considerably fewer miles per year on average than gasoline-powered vehicles. The difference is highly statistically significant and holds for both all-electric and plug-in hybrid vehicles, for both single- and multiple-vehicle households, and both inside and outside California. The paper discusses potential explanations and policy implications. Overall, the evidence suggests that today’s electric vehicles imply smaller environmental benefits than previously believed.  相似文献

Agricultural decision makers rely on information provided by public and private entities. Data is a valuable asset and represents a tremendous investment of resources. However, difficulty locating sources and/or interpreting values may compromise its usefulness. The Florida citrus industry serves as an example of the data problem faced by many users; over 50 publications produced by 13 agencies are identified as official sources of citrus data. An indication of the potential for lost value and the dilemma facing modern agriculture is provided. This paper draws on corporate information management techniques as a framework for adding value to agricultural data.  相似文献

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's.  相似文献

While the techniques become more sophisticated, the hardware and software go through new generations and we move towards such unexplored options as internet fundraising and legal restraints, the challenges and successes in the field of fundraising and in the personality of fundraisers should not change very much: they are faced with the assignment of making the donors feel important, the causes seem attractive, and making the system move with ease and comfort for everyone concerned. The author gives strong credence to such ‘simple’ matters as appearance, health, ethics, virtue and giving attention to words as well as innuendo. The reader will learn if he or she ‘listens’ to the message of this paper; if, on the other hand, he or she is looking for a shortcut or a foolproof plan short of living and loving in the field, it will not be found — in this or any other paper. Fundraising is a synergestic system: you put everything you know together, and it comes out to equal more than the sum of its parts. Still, you keep on learning. The best fundraiser has not yet been born; the most successful campaign has not yet begun; the wisdom is still being assembled. This paper is one man's overview of where we have been, what we are doing in best practice scenarios, and what is possible if we ‘Look sharp, feel sharp, be sharp and listen’; it includes a good overview of ‘Anecdotal excellence: people, places and things’. The paper starts with a word from God and ends with a reminder for us all: ‘We must remember — to look forward!’ Copyright © 2002 Henry Stewart Publications  相似文献

Extant work on costs of financial instability focuses on fiscal costs and declines in aggregate GDP following banking crises. We estimate effects of banking and currency crises on consumption in 19 OECD countries, showing consumption plays an important role in the adjustment following a crisis, and effects are not captured solely by the impact of crises on standard consumption determinants, income and wealth. Additional effects, attributable to factors such as time-varying confidence, uncertainty and credit rationing, are aggravated by high and rising leverage, despite financial liberalisation easing liquidity constraints. High leverage implies that banking crises taking place now could have greater incidence than in the past.  相似文献

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.
