This study specifies a procedure to quantify the determinants of sustainable crop production, and applies the method to wheat cultivation in the Tarai of Nepal. Three aspects of sustainability were considered. First, the fertility of the land was found to have deteriorated owing to long-term practices incompatible with soil and drainage conditions. Three-quarters of the farmers had reduced land fertility and for one-third of them the wheat yield was at least 20% lower than for farmers who applied farmyard manure to every crop and adopted a rotation consistent with soil and drainage conditions. Secondly, the study found that it was possible to improve resource-use efficiency in wheat production to give 25% higher production at current levels, type, and quality of farm resources. Resource-use efficiency was significantly related to farm management practices such as crop stand, variety, disease, and land preparation quality, and socio-economic factors such as off-farm job opportunities, poor plot accessibility, and migration. Thirdly, the increasing population pressure on land, decreasing livestock number per cropped area, and diminishing fuel wood sources, significantly reduced farm-based nutrient cycling because farmyard manure had to be used for fuel. This had implications for the higher use of the fossil-based inputs in crop production.  相似文献

We examine the performance of several types of the consumption-based CAPM (C-CAPM) models to explore if consumption factors matter for determining excess returns across 17 MSCI country indexes. While the classic world C-CAPM does exhibit some power in explaining cross-sectional variations of expected excess returns, the model seems to require an implausibly large coefficient of risk aversion. The more sophisticated models including the heterogeneous C-CAPM, the world surplus consumption and the habit-formation models provide more reasonable estimates and add substantial explanatory power for the variation in the cross section of excess stock returns. Our results suggest that country-specific consumption risk is not fully diversified thus implying that stock returns are related to idiosyncratic consumption risk.  相似文献

Business continuity planning is an important element of business continuity management and is regarded as a fundamental step towards reducing the negative impacts of business disruptions caused by internal and external hazardous events. Many businesses are not prepared for such events, and very few studies have tried to examine and model the factors that contribute to business continuity management planning by various companies. In this paper we propose and develop a feed‐forward neural network for modelling businesses continuity planning by businesses based on a dataset of 283 businesses operating in the Greater Toronto Area in Ontario, Canada. The fully connected neural network applied was trained on 65 % of the dataset records using different subsets of input variables. In order to preserve the generalization ability of the trained network, 15 % of the dataset records were used as a validation set for early stopping during the network's training process. Prediction capability of the trained networks was evaluated on 20 % and never‐seen records of the dataset. The classification ability of the networks was then analysed using receiver operating characteristic and detection error trade‐off curves, where the results obtained were promising. The equal error rate for the best models was 12 %, which reflects a very good accuracy of these models in predicting the existence of business continuity planning for a generic company.

Though the number of international joint ventures (IJVs) from developing countries has grown considerably, little has been reported on their operations and performance. The extant literature is based largely on IJVs from developed countries. To help fill this knowledge gap, this paper examines the determinants of stability from a study of 59 IJVs from developing and developed countries operating in a developing country. A multivariate model investigates the impact of a set firm, managerial and culture related factors on the stability of IJVs. Logistic regression analysis reveals that cooperation and physic distance between partners have significant impact on the stability of an IJV. There were no significant differences between stability rates for IJVs from developing and developed countries, but their determinants varied. The paper discusses the implications and limitations of the study, and identifies areas for further research.  相似文献

Managerial value systems along with individualism-collectivism concepts were examined among 768 managers in Iran. The sample was randomly selected from state, private, and mixed organizations. The participants ranked conformist and sociocentric values high. In addition, the participants displayed a high tendency toward collectivism and a weak commitment to individualism. Furthermore, existential value was highly correlated with individualism-collectivism measures.  相似文献

Current research into co-branding and brand extensions indicates that these marketing strategies benefit firms, yet marketing literature examines the concepts only independently. This article reports the findings of two studies, conducted among 256 students, that compare the effectiveness of co-branding versus brand extension strategies. The comparison of these strategies, both individually and concurrently, considers consumers' attitudes, quality perceptions, and purchase intentions toward a new product (i.e., Bluetooth-enabled sunglasses). The first study reveals that the presence of at least one high-equity brand in co-branding strategy suffices to leverage consumers' evaluations of a new product. However, the findings of the second study indicate no significant differences between co-branding and brand extensions in terms of consumer evaluations of an identical product.  相似文献

This study examines whether it is ever rational for analysts to post biased estimates and how information asymmetry and analyst experience factor into the decision. Using a construct where analysts wish to minimize their forecasting error, we model forecasted earnings when analysts combine private information with consensus estimates to determine the optimal forecast bias, i.e., the deviation from the consensus. We show that the analyst??s rational bias increases with information asymmetry, but is concavely related with experience. Novice analysts post estimates similar to the consensus but as they become more experienced and develop private information channels, their estimates become biased and deviated from the consensus. Highly seasoned analysts, who have superior analytical skills and valuable relationships, need not post biased forecasts.  相似文献

This study examines whether auditors are employed as a monitoring mechanism to mitigate agency problems arising from different types of controlling shareholders. In a context of concentrated ownership and poor investor protection, controlling shareholders can easily expropriate wealth from minority shareholders and profit from private benefits of control. However, this agency conflict has been rarely studied, as the most commonly assumed agency conflict occurs between managers and shareholders. Using an audit fee model derived from Simunic (1980), we study the impact of the nature of controlling shareholders on audit fees in French listed firms. Our results show: (1) a negative relationship between audit fees and government shareholdings; (2) a positive relationship between audit fees and institutional shareholdings; and (3) no relationship between audit fees and family shareholdings. These results illustrate the mixed effects of the nature of ownership on audit fees.  相似文献

This paper investigates the short-term market reaction of nine profit-efficiency, pre-classified merger deals of US banks over the time period from 1992 to 2003. The findings show that mergers combining low efficiency acquirers and targets create significant market returns following the merger event, while mergers combining the least efficient acquirers with moderately efficient targets diminish the acquirer's wealth more than any other type of merger. Furthermore, findings show that acquirers generally lose about 2.5% of their wealth upon the merger announcement while targets experience, on average, significant market returns of 15.5% following the merger announcement.The findings of the cross sectional analysis show that the CARs of acquirers are positively related to their technical efficiency and geographic diversification, while targets' CARs are negatively related to both target size and revenue efficiency.  相似文献

Data from 1,374 firms across four broad industrial groupings are used to assess the contribution that real (adaptation) options make to overall equity values. The analysis indicates that real (adaptation) options make a significant contribution to the equity value of firms with a market to book ratio (of equity) of around unity or less. As the market to book ratio grows beyond this level, however, the contribution made by real (adaptation) options decays quickly away and equity values are mainly comprised of the present value of the dividends that firms are expected to pay. This means that for around one in every five of the firms in our sample real (adaptation) options make a significant contribution to overall equity value. Thus, while linear equity valuation models would seem to be appropriate for the substantial majority of firms on which our sample is based, there is a sizeable minority of firms where real (adaptation) options have a significant impact on equity values. For this latter group of firms there will be a non-linear relationship between equity value and its determining variables. This has important implications for the regression procedures that are applied in this area of accounting research.  相似文献
