How is perceived inflation related to actual price changes in the European Union?

We analyze for which types of consumer expenditures the rate of price change influences consumer perception of inflation. We use both harmonized consumer price indices (HCPI) and series of perceived inflation from Eurostat in the 1996–2006 time period for 13 European countries. After removing substantial autocorrelation, we found a significant effect of the rate of overall price change on perceived inflation in the EU as a whole and a number of individual countries, supporting Fechner’s law. However, in different countries different consumer item categories were correlated with perceived inflation.     

Food Calorie Intake under Grain Price Uncertainty in Rural Nepal

This study evaluated the effects of grain output price uncertainty on the farm income of rural households and, consequently, how this uncertainty influenced caloric intake through changes in farm income. Using a national rural household survey data set in Nepal, augmented with output price uncertainty measures calculated from historical time-series data, we found that grain output price uncertainty (especially for rice and wheat) tends to decrease crop production income of rural households. In addition, we found that lower crop income from production decreases calorie intake of rural households. Taken together, these results suggest that output price uncertainty during the production process tends to reduce caloric intake of rural Nepalese households. The price uncertainty seemed to reduce the crop income households need to buy calorie-rich staple foods.

试论跨国公司内部贸易中的转移定价问题

转移价格是跨国公司在跨国经营中最常用的一种财务手段,跨国公司通过这一价格工具的应用,不仅能实现调整利润和资金、控制市场、避免税收等多重目标,而且对所在国的国际收支平衡、对外贸易甚至于经济发展模式都将产生很大的影响。监管与防范跨国公司转移定价需要培养一批高素质审计人才。应该深刻认识跨国公司实施转移定价的内部动机及国外反避税主要措施等问题。

Centralized versus Decentralized Competition for Price and Lead‐Time Sensitive Demand

We study two firms that compete on price and lead‐time decisions in a common market. We explore the impact of decentralizing these decisions, as made by the marketing and production departments, respectively, with either marketing or production as the leader. We compare scenarios in which none, one, or both of the firms are decentralized to see whether decentralization can be the equilibrium strategy. We find that under intense price competition, with intensity characterized by the underlying parameters of market demand, firms may suffer from a decentralized structure, particularly under high flexibility induced by high capacity, where revenue‐based sales incentives motivate sales/marketing to make aggressive price cuts that often erode profit margins. In contrast, under intense lead‐time competition, a decentralized strategy with marketing as the leader can not only result in significantly higher profits, but also be the equilibrium strategy. Moreover, decentralization may no longer lead to lower prices or longer lead‐times if the production department chooses capacity along with lead‐time.      

知识经济背景下影响价格制定与调整的心理因素研究

在知识经济时代,随着知识等新的价值因素在商品价格中所占比例的增大,消费者心理因素对价格的影响,变得比以往任何历史时期都更加显著。因此,只有深入研究这些因素,并在此基础上采用与之相适应的价格制定与调整的策略,才能实现既卖出商品获得利润,又能让消费者满意的双赢效果。     

基于神经网络房地产价格指数的预测研究

研究表明,房地产价格指数常表现为非线性,要对它进行预测就必须利用一种能模拟非线性的模型。从理论上讲,神经网络能够无限逼近非线性函数,所以本文便尝试采用神经网络模型作为预测的模型。本文具体运用的是基于误差反向传播算法的多层前馈网络(BP神经网络)和径向基函数(RBF)神经网络。首先利用BP神经网络对采集到的中国房地产价格指数进行训练和模拟,最后进行预测,并比较预测结果和真实值,发现误差比较大,一方面是因为选取的样本数据少,另一方面是因为BP神经网络本身具有缺陷。为了克服BP神经网络预测的缺陷,本文接着运用RBF神经网络对选取的数据进行训练和模拟,用训练好的网络来进行预测,得到的预测结果与真实值相比较,误差很小,而且RBF神经网络的运行速度要比BP神经网络快很多。经过比较可以得出RBF神经网络用于经济预测可以达到很好的效果。     

按质论价的经济学分析

按质论价是马克思价格理论中价格运行机制原理的简约表述。按质论价有两种形态。坚持按质论价对我国进一步深化市场化改革 ,充分发挥价格的运行、调控机制 ,加快经济结构的调整 ,规范市场秩序 ,提升经济运行质量 ,迎接“入世”和知识经济的挑战具有重要的理论和实践价值     

关于价格弹性理论的一点探讨

在价格弹性与销售收益之间的关系上 ,传统的价格弹性理论中存在着明显的缺陷 ,要增加销售收益 ,不仅要根据价格弹性是否大于 1来进行价格调节 ,而且在其他条件不变的情况下 ,价格调节本身必须在一定的幅度内进行
