This paper investigates the dynamic relationships between research and development (R&D) expenditure and productivity growth in Australian broadacre agriculture using aggregate time series data for the period 1953 to 2009. The results show a cointegrating relationship between R&D and productivity growth and a unidirectional causality from R&D to TFP (total factor productivity) growth in Australian broadacre agriculture. Using the dynamic properties of the model, data from beyond the sample period are analysed by employing the variance decomposition and the impulse response function. The findings reveal that R&D can be readily linked to the variation in productivity growth beyond the sample period. Furthermore, the forecasting results indicate that a significant out‐of‐sample relationship exists between public R&D and productivity in broadacre agriculture.  相似文献

To Schumpeter, endogenous development is an essential characteristic of capitalism that disrupts the equilibrium of the circular flow of the economy. Price equilibrium in the circular flow is displaced by an analysis of prices in motion. The diversion of productive inputs from their existing employment through competition from entrepreneurs and the process of creative destruction both impact on prices throughout the economy and generate business cycles. While Schumpeter's theory of the business cycle and, implicitly, his price theory, have been heavily criticized, this article suggests a way forward to a revised theory of prices in motion.  相似文献

To date, no sustainable treatment program exists for kidney failure in countries in sub-Saharan Africa. No data are available on the incidence, prevalence or cause of chronic kidney disease (CKD). The world's focus has been on treating 'priority diseases' as defined by the United Nations Millennium Project and the World Health Organization because of their high mortality rates. This is understandable because HIV/AIDS, tuberculosis, diarrheal diseases and malaria claim majority of the lives; however, in many cases, the mortality is due to acute renal failure (ARF) as a consequence of the progression of these diseases. Moreover, to date, no data are available on mortality rates due to ARF as a consequence of these 'priority diseases.' Sustainable Kidney Care Foundation (SKCF), working with industry, institutions, universities and funding organizations, is in the process of establishing a pilot program for the treatment of acute renal failure (ARF) using peritoneal dialysis (PD) as the modality of choice with a special focus on treating children and women of childbearing age in the United Republic of Tanzania.  相似文献

To build this process it is necessary to consult customers for preferences, build familiarity and knowledge to build a relationship and conduct business in a customized fashion. The process takes every opportunity to build customer satisfaction with each customer contact. It is an important process to have, since customers today are more demanding, sophisticated, educated and comfortable speaking to the company as an equal (Belk, 2003). Customers have more customized expectations so they want to be reached as individuals (Raymond and Tanner, 1994). Also, a disproportionate search for new business is costly. The cost to cultivate new customers is more than maintaining existing customers (Cathcart, 1990). Other reasons that customer retention is necessary is because many unhappy customers will never buy again from a company that dissatisfied them and they will communicate their displeasure to other people. These dissatisfied customers may not even convey their displeasure but without saying anything just stop doing business with that company, which may keep them unaware for some time that there is any problem (Cathcart, 1990).  相似文献

作为对分析哲学的令人欣喜的贡献,刘悦笛的《分析美学史》,有助于形成对20世纪西方社会中的哲学美学的整体进程的基本理解。刘悦笛的文本正确估价了分析哲学对于美学研究的贡献,其所追踪的历史进程横亘了整个20世纪。这项任务主要是通过从美学家的贡献到美学主题的贡献的诸章节来共同实现的,每章在介绍与总结的部分都提出了作者自己对于分析美学重要性的解释和评价。刘悦笛所选择的美学家们对于这部分析美学简史而言是毫无疑义的,因为他们形成了在这场运动当中的最重要的形象。这种选择代表了一种系统的结构,这对于非西方读者们更深入地理解分析美学具有特别的重要价值。在对历史的精细的组织与敏锐的洞见当中,刘悦笛所提供的坚实的基础,对于学者和学生们而言就像一个坚实的平台,可以由此去探索那些在分析美学史上提出令人瞩目的理念的人们的作品。  相似文献

The foreign policy literature typically sees Congress abdicating its policy making role to the executive, implying a presidential dominance model is superior to other policy process models (joint participation, congressional dominance, and bureaucratic dominance). This article uses two theoretical approaches to investigate who actually makes U.S. trade policy: a political economy approach and an institutional approach. We look at the 1985 96 period and at individual presidencies: Reagan (1985-88), Bush (1989-92), and Clinton (1993-96). Contrary to the literature, we find strong evidence that Congress is an active participant in the trade policy making process. Using a variety of empirical techniques (crosstabs, the Index of Revealed Comparative Advantage, pairwise correlations, and stepwise logistic regressions), we confirm that the trade policy process for product-industry-specific policies tends to be dominated by Congress whereas the executive branch is more influential in the policy process for country-specific policies. We conclude by noting the advantage of integrating aspects of both the political economy of trade and institu tional literatures to understand the nuances of U.S. foreign trade policy making.  相似文献

Housing tenure choice has been the subject of a very large literature. Many treatments have sought to estimate the effect of household income on the likelihood of home ownership. To date, no study has ever disaggregated the household income of married couples into the separate labor income components to see if one partner’s income has a different effect than the other. Using a derived likelihood function to control for censoring in the wife’s income, this paper estimates the effect of separate incomes on housing tenure choice, accounting for possible endogeneity of the wife’s income. To compare the results of this estimation method, the paper also estimates the standard IV models, 2SLS and IV probit. While the results show that there is no endogeneity of the wife’s income, ignoring the censoring of the endogenous variable (when a large fraction of observations are censored) can possibly lead to biased coefficient estimates. Also, this paper confirms the importance of total household income, which has a larger effect than the total disaggregated components.  相似文献

This paper broadly explores changing outdoor recreation demands, environmental opinions and demographics in the United States. With this country's population predicted to more than double by the end of this century, it is imperative that we understand these trends and their implications for better managing our natural environment and providing opportunities for outdoor recreation in that environment. Using national survey data, we have described differences in recreation behavior (participation) and environmental attitudes nationwide across six socio-demographic factors-race, country of birth, rural-urban residence, region of the country, age and income. Results indicate that demographic differences, recreation activity choices and people's environmental positions are linked.  相似文献

Interconnection in Network Industries   总被引:4,自引:0,他引:4  
Recent deregulation of telecommunications in the U.S. and elsewhere has highlighted the importance of interconnection in network industries. In this paper, we analyse interconnection in a deregulated network where the participants compete in the final retail market. We consider both the case of a mature industry as well as one where a new entrant challenges the incumbent. In the later case, network externalities allow the incumbent to use the terms of interconnection to maintain its dominant position. Moreover, in either case, competition in the retail market can be undermined by collusion over access prices. We discuss the implications for some of the provisions of the new U.S. Telecommunications Act, specifically mandatory interconnection and reciprocity of tariffs, comparing these to the simple bill and keep rule.  相似文献
