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

Private equity performance, both for buyouts and venture capital, has been highly cyclical: periods of high fundraising have been followed by periods of low performance. Despite this seemingly predictable variation, we find modest gains, at best, to pursuing realistic, investable strategies that time capital commitments to private equity. This occurs, in part, because investors can only time their commitments to funds; they cannot time when commitments are called or when investments are exited. There is a high degree of time-series correlation in net cash flows even across commitment strategies that allocate capital in a very different manner over time.  相似文献

When evaluating mutually exclusive projects of unequal lives and with differing risk, standard approaches such as the constant chain of replacement, lowest common multiple and equivalent annual value techniques are usually applied. In using these techniques to rank projects, a critical issue is the manner in which uncertainty in the cashflows is resolved through time. We explore the applicability of net present value techniques to the problem of valuing assets with unequal lives, emphasising the use of equivalent annual value and lowest common multiple methods, and the correct choice of discount rate. Our results have direct application to practical capital budgeting problems such as choosing the optimum lifespan for a single asset, choosing between assets with different lifespans, and deciding whether to "run an asset for another year".  相似文献

Social marketing involves influencing voluntary behaviour of people towards a social end. Examples of social marketing range from campaigns to encourage healthy physical behaviour to efforts to encourage tax support for public education, overcome racism, or stimulate ‘patriotic’ behaviour. Using data from a summer 2001 telephone survey of 600 young adults, this paper investigates how recruitment campaigns may benefit from considering gender differences in importance ratings of a variety of benefits promoted by the military in the USA. Importance ratings are assessed using differences in means and variances tests. Findings identify gender specific differences that may be used to enhance recruitment campaigns.

An econometric model is used to measure the impact of the Three-Party Programme on European demand for U.S. orange juice. The results show that the programme has helped expand the demand for orange juice in European countries and, from the viewpoint of the U.S. citrus industry, is an economically preferred way of generating additional exports compared with using price reductions to achieve additional sales.  相似文献

This paper examines the process of interaction between consumers and providers of dental services in terms of the key selection and evaluation criteria employed by consumers. Focusing on the United Kingdom, it examines the impact of changes in both pricing and provision on the utilisation and evaluation of dental services. Based on a questionnaire survey of dental patients, in the context of the evolving body of literature concerned with consumer behaviour in respect of services, the paper attempts to improve the current understanding of the key factors shaping consumer choice in respect of professional services. Specifically, it argues that the highly complex nature of professional services impacts on patterns of consumer behaviour, resulting in the relationship between the individual service professional and the consumer being the focus of consumer evaluation. This in turn has significant implications for the effective marketing of such professional services.  相似文献
