We examine whether the use of the three‐moment capital asset pricing model can account for liquidity risk. We also make a comparative analysis of a four‐factor model based on Fama–French and Pástor–Stambaugh factors versus a model based solely on stock characteristics. Our findings suggest that neither of the models captures the liquidity premium nor do stock characteristics serve as proxies for liquidity. We also find that sensitivities of stock return to fluctuations in market liquidity do not subsume the effect of characteristic liquidity. Furthermore, our empirical findings are robust to differences in market microstructure or trading protocols between NYSE/AMEX and NASDAQ. 相似文献

Summary The exact mean square error for the ratio estimator of a finite population total based on simple random sampling without replacement
is shown to have an expected value less than that of the variance of the ratio estimator based on Midzuno’s scheme, under
a usual super-population model. 相似文献

The present study empirically examines the contribution of the acquired banks in only the nonconglomerate types of mergers
(i.e., banks with banks), where the bulk of the payment is in the form of equity to the acquiring bank and finds overwhelmingly
statistically significant evidence that nonconglomerate types of mergers definitely reduce the total as well as the unsystematic
risk while having no statistically significant effect on systematic risk. Therefore, it seems that diversification may be
a possible motive for bank mergers. 相似文献

The study of climatic variables that govern the Indian summer monsoon has been widely explored. In this work, we use a non-linear deep learning-based feature reduction scheme for the discovery of skilful predictors for monsoon rainfall with climatic variables from various regions of the globe. We use a stacked autoencoder network along with two advanced machine learning techniques to forecast the Indian summer monsoon. We show that the predictors such as the sea surface temperature and zonal wind can predict the Indian summer monsoon one month ahead, whereas the sea level pressure can predict ten months before the season. Further, we also show that the predictors derived from a combination of climatic variables can outperform the predictors derived from an individual variable. The stacked autoencoder model with combined predictors of sea surface temperature and sea level pressure can predict the monsoon (June-September) two months ahead with a 2.8% error. The accuracy of the identified predictors is found to be superior to the state-of-the-art predictions of the Indian monsoon. 相似文献

The present paper examines the issue of whether interpersonal relationships are critical for global marketing of industrial products. The fields of relationship marketing, IMP group research, sales research, and network theory have stressed the importance of interpersonal relationships in the business-to-business or industrial marketing context. In contrast to this emphasis on interpersonal relationships, we argue that industrial firms can both conceive and enhance marketing strategies based on developing high quality and consistent processes, products, services or outcomes (consistent processes and outcomes). Such strategies are especially important given the fact that developing interpersonal relationships is expensive due to their reliance on frequent and/or face-to-face communications. In this paper, we examine industry and country contexts that lead to the choice of alternative industrial product marketing strategies and highlight some future research directions and managerial implications. 相似文献

Evaluation of subsidiary marketing performance: combining process and outcome performance metrics 总被引:1,自引:0,他引:1

Issues in evaluating marketing performance and devising appropriate metrics for measurement have taken center stage in marketing
thought and practice in recent years. We propose an empirical model that enables a multinational enterprise (MNE) to assess
the marketing performance of its subsidiaries, taking into explicit consideration the fact that tactical actions by subsidiaries
contribute to the creation of assets that can be harnessed for marketing outcomes. Thus, our model captures the asset creation
abilities of marketing expenditures and also takes in to account the environmental differences of the context in which each
MNE subsidiary operates. We evaluate comparative, overall, and process-level (creation of market assets and market yield)
marketing performance in the context of multi-country operations. This simultaneous examination of marketing process and marketing
outcome performance enables a global corporation to gain strategic, operational, and diagnostic insights into the performance
of its subsidiaries. Our approach is empirically illustrated with an evaluation of the marketing performance of subsidiaries
of a large global corporation. 相似文献

With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies. 相似文献
