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

Companies in the United States are concerned with retaining minority employees to maintain or increase the diversity of their workforce. Here we assess the value of one approach companies have used to retain minority employees: “network” groups. Based on data obtained from a large company with extensive network groups, this study compares the turnover intentions of minority employees who have joined one of the company's network groups to those who have not joined one of the company's network groups. The data show that employee network groups can be useful in helping companies retain managerial‐level minority employees. Extensive recommendations are provided to help organizations maximize the effectiveness of network groups. © 2002 Wiley Periodicals, Inc. 相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. 相似文献

This article proposes a new forecast combination method that lets the combination weights be driven by regime switching in a latent state variable. An empirical application that combines forecasts from survey data and time series models finds that the proposed regime switching combination scheme performs well for a variety of macroeconomic variables. Monte Carlo simulations shed light on the type of data‐generating processes for which the proposed combination method can be expected to perform better than a range of alternative combination schemes. Finally, we show how time variations in the combination weights arise when the target variable and the predictors share a common factor structure driven by a hidden Markov process. 相似文献

The dynamic relationship linking the volatility of equity prices with “the news” and the expected path for monetary policy
is investigated. Previous results that link the impact of the news about real activity to changes in current and future interest
rates are employed in developing a positive link between changes in volatility and the news. Empirically, our results uncover
a positive and statistically significant response of the CBOE volatility index, VIX, to unanticipated changes in employment,
but not to inflation. Hence, agents' expectations for the policy response to news have an important influence on the expected
volatility of stock prices. (JEL E44, E52) 相似文献
