Various combination of Natural Language Processing and Machine Learning methods offer ample opportunities wherever texts are an important element of an application or a research area. Such methods discover patterns and regularities in the data, seek generalization and in effect learn new knowledge. We have employed such methods in learning from a large amount of textual data. Our application is electronic negotiations. The genre of texts found in electronic negotiations may seem limited. It is an important research question whether our methods and findings apply equally well to texts that come from face-to-face negotiations. In order to confirm such more general applicability, we have analyzed comparable collections of texts from electronic and face-to-face negotiations. We present our findings on the extent of similarity between these two related but distinct genres. In this study we have analyzed similarities in the text data of electronic and face-to-face negotiations. The results show that – in certain conditions – vocabulary richness, language complexity and text predictability are similar.This is an expanded version of a paper published in the Proceedings of FINEXIN 2005 (Workshop on the Analysis of Formal and Informal Information Exchange during Negotiations), 31–42, Ottawa, Canada, May 2005. 相似文献

Some attribute China's rapid economic growth to a cadre promotion system that rewards economic performance. Others argue that political promotion in China hinges on factionalism. Extant empirical studies often assume that performance can be measured independently from the effect of factionalism. We test the validity of this assumption by examining whether local cadres’ economic performance would change as a result of losing vertical ties to a higher authority. We find an immediate increase in the growth rates of local GDP and government revenue. However, the performance change is mediated by the type of succeeding leaders, as it occurs only under locally promoted leaders who have existing ties with the local cadres. We further examine various channels through which a leader's insider status may affect local economic performance and find that newly appointed outsider leaders would cut fiscal transfers to the local level, which may explain the drop in their short‐term performance. 相似文献

Fermentation of livestock manure for the production of biogas is not economically viable given current and prospective energy prices, as long as the residue from the fermentation process is used on agricultural land as a source of crop nutrients. An alternative use of the residue is to separate out the solid fraction for use as a source of protein and minerals for livestock. This alternative was evaluated for a commercial beef feedlot in Ontario, and was found to provide attractive returns using feed replacement values for the residue solids, even when a zero value was attributed to the biogas, and when real interest rates reached 7 percent. Economies of size were also found. 相似文献

This paper explores the dynamics of market selection for an industry in which firms employ relatively simple pricing, production
and investment routines and in which consumers switch between rival firms in response to price differentials but do not all
do so instantaneously. The key issue is whether market processes result in the elimination of less efficient firms by their
more efficient rivals. That is to say, do such processes unfailingly increase the efficiency with which available economic
resources are used? In the context of duopoly, we show that the survival of the more efficient firm is not guaranteed and
that, more generally, the outcome depends upon the speeds with which firms adjust prices and capacities and with which customers
switch between rival firms. 相似文献

Standard deviations implied in option prices have recently been introduced as being better than average predictors of future stock price variability. This article specifically studies the predictive ability of implicit standard deviations, taking into account the dividend problem and the problem of optimal weighting schemes of the standard deviations when there are several options on the same stock. Transaction data information was used to study the importance of non-simultaneities in observing stock and option prices. 相似文献

The paper investigates the relationship of the degree of tacit collusion among existing sellers on industry price when a threat of entry exists. A general model is developed which allows comparison of two seemingly unrelated strands of the limit pricing literature. 相似文献

Fractional factorial experiments are very useful in identifying active factors and the conventional method of analysis may not always detect these active factors. Box and Meyer (1993) provided a Bayesian method to compute the posterior probability that a factor is active. Their method does not indicate whether main effects or interactions are active. Following their approach in a non-Bayesian way, we will present a heuristic analysis which determines the active main effects and small order interactions in any 2n fractional factorial design. It may be noted that the method given by Box and Meyer has greater flexibility and wider applicability over the method given in this paper; however, our method is a simpler alternative for 2n experiments that determines active main effects and small order interactions.
