In the present paper, we model the policy stance of the People's Bank of China (PBC) as a latent variable, and the discrete changes in the reserve requirement ratio, policy interest rates, and the scale of open market operations are taken as signals of movement of this latent variable. We run a discrete choice regression that relates these observed indicators of policy stance to major trends of macroeconomic and financial developments, which are represented by common factors extracted from a large number of variables. The predicted value of the estimated model can then be interpreted as the implicit policy stance of the PBC. In a second step, we estimate how much of the variation in the PBC' s implicit stance can be explained by measures of its policy objectives on inflation, growth and financial stability. We find that deviations of CPI inflation from an implicit target and deviations of broad money growth from the announced targets, but not output gaps, figure significantly in the PBC's policy changes. 相似文献

Using generalized impulse response functions, this study tests for the trade J‐curve for three transitional central European countries – the Czech Republic, Hungary, and Poland – in their bilateral trade with respect to Germany. Our findings suggest that for each country there are some characteristics associated with a J‐curve effect: after a (real or nominal) depreciation the export‐to‐import ratio briefly drops to below its initial value within a few months and then rises to a long run equilibrium value higher than the initial one. 相似文献

How does a firm keep on being valuable in a network? One requirement is that the firm has a sufficient overview of the network and its dynamics. In other words, a firm's strategy depends on the firm's overview of the network—its network horizon. How comprehensive or limited should its network horizon be? Is it necessary to know the network beyond the direct counterparts? Such issues have not received much attention. In this article, we discuss network horizons and argue that limited network horizons are both inevitable and useful. However, such myopia requires that a firm's counterparts effectively and efficiently mediate between the firm and the rest of the network. Based on a case study, we introduce and discuss three mediating functions of counterparts: a joining, a relating, and an insulating function, and we claim that in order to support a firm's strategizing, managers need to analyze and influence counterparts' mediating functions and thereby the firm's network horizon. 相似文献

This article considers a linear regression model with some missing observations on the response variable and presents two
estimators of regression coefficients employing the approach of minimum risk estimation. Small disturbance asymptotic properties
of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice,
for the superiority of one estimator over the other are derived.

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents. 相似文献

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the
last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the
current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of
the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The
results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current
account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted
expected change in future net output, does not follow the actual behaviour of the current account.

产品包装废弃物对生态环境产生严重影响:使城市的生态环境污染加剧.占用大量的耕地,使蚊蝇滋生,造成资源的大量浪费。产品包装废弃物的回收与利用可产生巨大的经济效益和社会效益,但必须解决如下几个问题:地方政府职能缺位、法律体系不健全和有法不依、国民环境意识淡薄及企业社会责任缺失。 相似文献

自主创新是当前商业界和学术界研究比较热的话题。政府相应地制定了一系列的政策和法规来鼓励企业进行自主创新。在这种背景下,我国的医药企业也积极响应国家的政策进行自主创新。然而,医药企业创新在实际操作中的行动方向差异很大。针对这种差异,笔者将医药企业创新划分成新功能创新和新设计创新两种,并且通过对一系列的数据和资料分析后,发现我国的医药企业的创新并非实质上的自主创新即新功能创新,而是新设计创新。文中对产生这种局面的演化机制进行了分析。 相似文献
