Modern irrigation technologies have been suggested as a means of conserving scarce water and reducing environmental pollution caused by irrigated agriculture. This paper applies an economic model of technology selection that provides a general framework to analyzing adoption of irrigation technologies under various environmental conditions. Data from the San Joaquin Valley of California is used to verify the theoretical relationships. Results suggest key variables to be considered by policy makers concerned with adoption of modern irrigation technologies. Among these variables are crop prices, water technology costs, farm organization characteristics, and the environmental conditions of the farm or the field. Policy implications were discussed and analyzed.This research was conducted while the first author was a visiting scholar with the Dept. of Agricultural Economics, University of California, Davis, and USDA-ERS, USA.  相似文献

Adoption and abandonment processes are analyzed for seven irrigation technologies. A procedure is developed to estimate the technology cycle and applied to data available for citrus groves in several regions of Israel, and Gaza. The technology cycle was used to estimate diffusion-abandonment patterns for several irrigation technologies that have been abandoned. Results suggest that the technology cycle is unique to each technology and similar in length for all regions. Results predict the year of full abandonment of each technology. For modern technologies still in the diffusion phase, a logistic equation was fitted to the aggregated data. Results suggest that diffusion is significantly affected by economic variables such as water price, crop yield price, and subsidy for irrigation equipment. Use of the estimated equations for policy purposes suggest that water price and subsidy for irrigation equipment can be used to control the diffusion process (speed and ceiling) of the irrigation technologies.  相似文献

Firms in transition economies experienced a large exogenous shock in their external business environment in the late 1980s when these economies moved from a socialist‐oriented economic environment to a more market‐oriented economic environment. This paper examines the following research question in the context of this change: What are some factors that influence transition economy firms to successfully change their operating know‐how or knowledge sets to reflect the demands of their new environment? Building on some core ideas from literature on organizational imprinting, knowledge‐based view of the firm, and firm search, we suggest that two factors have a profound impact on a firm's ability to change. The imprinting effect of firms' prior socialist institutional and market environment adversely impacts their ability to change their operating knowledge. At the same time, firms that search for new knowledge from distant sources (located in mainly non‐socialist countries) are able to successfully change their knowledge to meet the demands of the new market‐oriented economy. Both of these aspects also have joint interdependent effects on the success of change; distant search mitigates some of the adverse impact of socialist market imprinting, but that is not the case for the impact of socialist institutional imprinting. These findings have interesting implications for both researchers and practitioners involved in transition economy settings. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Agricultural research that increases knowledge is an important component of agricultural productivity and development. This paper focuses on understanding and formulating the interactions among factors involved in the knowledge production process. A conceptual mode of research input-output relationships is developed based on the existing literature. These relationships are estimated based on cross-sectional time-series data for the public research system in Israel. Research resources (inputs) such as direct cost and senior scientific manpower were found to extend knowledge production, while resources such as junior researchers and technicians were found to be nonsignificant. Use of the estimated functions for forecasting and control of agricultural development is also illustrated.  相似文献

This article aims to examine the long-run equilibrium relationship between bilateral trade linkages and stock market correlations of Australia and China using quarterly data from 1993 to 2015. Further, this study explores the impact of trade intensity on stock market correlations using OLS, Dynamic OLS (DOLS) and Fully Modified OLS (FMOLS) models. The empirical results confirm that there is a significant long-run relationship among the variables. In addition, our results, based on OLS, DOLS and FMOLS, show that increasing trade intensity between Australia and China has a significant and positive impact on their stock market correlations. The Global Financial Crisis also contributed for their stock market interdependence. Our results therefore suggest that the bilateral trade relations between Australia and China have brought their stock markets together over time. The findings of this study offer significant policy and practical implications. The policymakers need to be aware of the economic changes in those countries as they will immediately reflect on their stock market performance and relationship. Similarly, the global investors need to be aware of the fact that the diversification opportunities between Australia and China have considerably declined over time as their markets became more interdependent in the recent past.  相似文献

This paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities. Cooperation allows users to internalize the damages caused by their activities and reduce extractions. The paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub-aquifers that are being overly exploited. Two types of externalities are modeled: first, water extractions in each sub-aquifer impact water levels in neighboring sub-aquifers (extraction externality). Second, the three sub-aquifers are also connected to an ecosystem and thus decisions in each sub-aquifer affect the health of the ecosystem (environmental externality). A cooperative game theory model is applied. The model empirically shows how the uncontrolled extractions in each sub-aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem. The model is tested empirically in one of the most important aquifers in Spain, the Eastern la Mancha aquifer. The results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users. The paper estimates the value of cooperation and its stability with and without the environmental externality.  相似文献

This study endeavors to empirically analyse the influential effect among brand prestige, service quality, casino visitor satisfaction and spend. Data from 304 tourists who had travelled to Macau and had participated in gambling activities were used and structural equation modelling and multi-group analysis were employed in hypotheses testing. The findings demonstrated that both brand prestige and perceived service quality are determinants of satisfaction and gaming spend, and that brand prestige also affects service quality positively. Furthermore, past experience moderates the service quality and visitors’ satisfaction relationship, also service quality and visitors’ gaming spend relationship.  相似文献

Escalation of commitment in new product development has been studied extensively for the last four decades but the impact of culture on the escalation phenomenon remains largely unexplored. This study investigates how culture impacts the decision to escalate or deescalate commitment to new products. Americans are analytic thinkers whereas Chinese tend to be holistic thinkers. When it comes to decision making, analytic thinkers focus on field independent and abstract factors and believe that future is linear and static, whereas holistic thinkers focus more on contextual factors and believe that future is dynamic and nonlinear. Hence, Chinese are more likely to escalate their commitment relative to Americans on receiving a negative performance report in the new product development process. A lab experiment using weekend MBA students and managers was used to test this underlying hypothesis. The findings confirmed that analytical thinkers use fewer factors than holistic thinkers in making new product decisions, and that Chinese managers are more likely to escalate their commitment relative to American managers. The decision to escalate or de-escalate was moderated by perceived product innovativeness.  相似文献
