Over the past decade, organizations all over the world have adopted enterprise resource planning (ERP) systems. There has been little research at a global scale regarding the accounting benefits of adopting enterprise systems. Moreover, there are virtually no studies that examine in detail the relation between accounting benefits and ERP user satisfaction. Sutton (2006) addressed the need for empirical research on the impact of ERP in terms of accounting advantages and disadvantages. The principal aim of our study was to investigate the accounting benefits that the adoption of an ERP system by companies may entail in relation to ERP user satisfaction. This study explored the impact that the ERP system has had on accounting information and practice. This study also examined whether or not there are differences between accountants and IT professionals concerning how each group assesses ERP accounting benefits and ERP user satisfaction. The participants of this study comprised 175 accountants and 96 IT professionals from 193 companies in Greece. The empirical evidence confirms a number of accounting benefits derived from ERP systems particularly for accounting process. No statistically significant differences were found between the perceptions of accountants and IT professionals concerning ERP accounting benefits. Furthermore, this research identifies factors related to accounting benefits and ERP cost which affect the level of ERP user satisfaction. The implications of these results for practice and research are explored. The findings of this study will be of value to any companies considering the inclusion of their accounting techniques and operations in an ERP system. Furthermore, the results of this study will provide stimulus for consequent research in the field in order to further examine and account for the accounting benefits that can occur from ERP system implementation as well as the effect of those benefits on ERP user satisfaction.  相似文献

After 20 years of neglect by international donors, agriculture is now again in the headlines because high food prices are increasing food insecurity and poverty. In the coming years, it will be essential to increase food productivity and production in developing countries, especially in Sub-Saharan Africa and with smallholders. This, however, requires finding viable solutions to a number of complex technical, institutional, and policy issues, including land markets, research on seeds and inputs, agricultural extension, credit, rural infrastructure, connection to markets, rural non-farm employment, trade policy and food price stabilization. This paper reviews what the economic literature has to say on these topics. It discusses in turn the role played by agriculture in the development process and the interactions between agriculture and other economic sectors, the determinants of the Green Revolution and the foundations of agricultural growth, issues of income diversification by farmers, approaches to rural development, and issues of international trade policy and food security, which have been at the root of the crisis in agricultural commodity volatility in recent years.  相似文献

To compete with the flood of environmental messaging from corporations and industry groups, environmental advocacy groups must adopt the most effective communication strategies to connect with audiences and motivate their behaviors toward environmental issues. This study examines the framing of environmental messages by advocacy groups in contrast to messages by other organizations in 30 years of environmental advertising in National Geographic Magazine. It measures changes in the degree to which environmental actions were framed in terms of gain for the environment versus avoidance of ecological loss and in terms of impacting current generations versus future generation. In addition, the study examined behavioral frames of taking less (conservation) versus doing more (recycling, volunteering, etc.) in environmental advocacy groups' advertising to better understand the kinds of actions the organizations are promoting. The organizations' strategies to engage audience behavior were also measured through message focus on reader behavior versus organization behavior. Findings suggest that frames engaged by environmental advocacy organizations have remained fairly stable over time but may not represent the best practices for message creation.

Despite an extensive body of research, the best way to model the dependence of exchange rates remains an open question. In this paper we present a new approach which employs a flexible time-varying copula model. It allows the conditional correlation between exchange rates to be both time-varying and modeled independently from the marginal distributions. We introduce a dynamic specification for the correlation using the Fisher transformation. Applied to Euro/US dollar and Japanese Yen/US dollar, our results reveal a significantly time-varying correlation, dependent on the past return realizations. We find that a time-varying copula with the proposed correlation specification gives better results than alternative dynamic benchmark models. The dynamic copula model outperforms at six different time horizons, ranging from hourly to daily, confirming the model specification.  相似文献

This paper investigates the impact of monetary incentives on whole blood donations. We take advantage of a quasi‐natural experiment in Germany, in which one blood donation site changes its payment scheme from remunerated to non‐remunerated. All other donation sites maintain their payment schemes. We show that donation volumes drop significantly after the pay drop and do not recuperate. At the same time, donation volumes increase at other paid donation sites, which is partly due to donor migration to these sites. We do not find any impact of the changed payment scheme on blood quality. Our results offer additional insight into the complex question whether it is efficient to ensure blood supply by paying donors a direct monetary compensation.  相似文献
