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

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

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate the model for 127 countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be in a low output equilibrium. We also find that, since the output gains associated with an equilibrium switch are sizeable, the model can explain between 15 and 25% of the variation in the logarithm of GDP per worker across countries.  相似文献

This paper investigates the relative importance of scheduled U.S. macroeconomic news releases for stock valuation. The study focuses on 11 macroeconomic announcements selected on the basis of the previous literature and the Bureau of Labor Statistics classifications of major economic indicators. The paper shows that five out of the 11 announcements have significant influence on stock valuation. These are the Employment Report, NAPM (manufacturing), Producer Price Index, Import and Export Price Indices, and Employment Cost Index. Of these six announcements, the Employment Report and NAPM (manufacturing) exert the greatest influence. The time of the announcement, measured by days from the beginning of the month to the release day, has a moderating impact on the relationship between macroeconomic announcements and its importance.  相似文献

A series of social accounting matrices (SAMs) are developed in this paper from first principles. Starting with the basic concepts of an institution, real assets and financial claims, the notions of a transaction and production are introduced, and it is shown that a SAM can be developed from the fundamental transactions identity. Accounts for real assets and financial claims are then grafted on to this initial SAM by reference to a similarly fundamental assets identity. Hence, a fully articulated SAM framework is developed which covers institutions, production, assets and their appreciation.  相似文献

One basis for the managerial theories has been the strong correlation between firm size and executive remuneration. This may, however, simply reflect variations in managerial quality across firms. We also show that the absence of a correlation between profitability and remuneration is not evidence in favour of the managerial theories. In this paper we follow the rewards to individual U.K. managers over time, thereby controlling for quality variation. We conclude that growth is highly rewarded and involvement in mergers and takeovers attracts an extra premium. This may explain the continued popularity of mergers despite knowledge of their general unprofitability.  相似文献

Does Corporate Diversification Destroy Value?   总被引:15,自引:0,他引:15  
We analyze several hundred firms that expand via acquisition and/or increase their number of business segments. The combined market reaction to acquisition announcements is positive but acquiring firm excess values decline after the diversifying event. Much of the excess value reduction occurs because our sample firms acquire already discounted business units, and not because diversifying destroys value. This implies that the standard assumption that conglomerate divisions can be benchmarked to typical stand-alone firms should be carefully reconsidered. We also show that excess value does not decline when firms increase their number of business segments because of pure reporting changes.  相似文献
