This paper examines the relationship between internationalization and performance in Chinese MNEs using panel data on 887 publicly listed Chinese firms over the nine-year period. A second aim of this paper was to test for the effects of the geographic regions where Chinese firms internationalize on their performance. The results show that the internationalization-performance relationship varies significantly depending on whether internationalization takes place within the Greater China region, within Asia or outside Asia. Internationalization within the Greater China region had the greatest benefit, the effect remaining positive and significant even after taking into account reverse causality effects. 相似文献

Civil unrest can range from peaceful protest to violent furor, and researchers are working to monitor, forecast, and assess such events to allocate resources better. Twitter has become a real-time data source for forecasting civil unrest because millions of people use the platform as a social outlet. Daily word counts are used as model features, and predictive terms contextualize the reasons for the protest. To forecast civil unrest and infer the reasons for the protest, we consider the problem of Bayesian variable selection for the dynamic logistic regression model and propose using penalized credible regions to select parameters of the updated state vector. This method avoids the need for shrinkage priors, is scalable to high-dimensional dynamic data, and allows the importance of variables to vary in time as new information becomes available. A substantial improvement in both precision and F1-score using this approach is demonstrated through simulation. Finally, we apply the proposed model fitting and variable selection methodology to the problem of forecasting civil unrest in Latin America. Our dynamic logistic regression approach shows improved accuracy compared to the static approach currently used in event prediction and feature selection. 相似文献

This paper investigates the aggregate cash inflows and outflows of domestic equity mutual funds as well as their net flows for the U.S. and Japan in an international context. The U.S. and Japan are two representative countries that have the largest and most developed fund markets in the Western world and Asia, respectively. For the purpose of analyzing dynamic relationships between market volatility, market return, and cash flow, this paper employs reduced-form and structural vector auto-regression (VAR) models. The analysis shows much different empirical findings between the U.S. and Japan, which can be explained by different culture and investment sentiments. 相似文献

The pricing of low-cost carriers (LCCs) compared with traditional airlines has been extensively investigated since their inception in the air transport market. Abundant empirical evidence attests that, on average, LCCs' fares (per km) are lower than those usually offered by full-service carriers (FSCs). Such literature, however, paid virtually no attention to the conditions under which LCCs lose their convenience compared to traditional airlines. The purpose of this study is to investigate the occurrence of LCCs sometimes offering higher fares than FSCs on competing flights. By using a dataset expressly collected for this purpose, we are able to quantify its frequency and suggest some possible explanations. These findings concur to cast some questions on the widely held preconception of vertical differentiation between LCCs' and FSCs’ offered services. Further research will be needed in order to understand the relative weight of the suggested factors. 相似文献

The Marshallian Macroeconomic Model in Zellner and Israilevich (2005) provides a novel way to examine sectoral dynamics through the introduction of a dynamic entry/exit equation in addition to the usual demand and supply functions found in models of this class. In this paper we examine the possibility of cyclical behavior in the Marshallian Macroeconomic Model and investigate the existence of a Hopf bifurcation with respect to the parameter in the entry/exit equation. 相似文献

We consider a dynamic competition game involving three players, in which each player can vary the extent of his competition on a per-rival basis. We call such competition targeted. We show that if the players are myopic, then the weaker players eventually lose the game to their strongest rival. If instead the players are sufficiently far-sighted, then all three players converge in their power and stay in the game. We develop our model in application to drug wars, but the approach of targeted competition can be applied to competition between firms or political parties, or to warfare. 相似文献

Recent marketing studies use scanner data to diagnose the influence of a change in a brand's marketing mix on other brands in the same category. A few studies also use scanner data to model inter-category effects between substitutes (e.g., tea and coffee) or complements (e.g., tea and sugar). No study models the dynamic effects of cross-category competition though.We present a dynamic model that shows how different products in a typical market basket influence demand of one another. Empirical tests use single-source, market-level data for ice cream and some substitute and complement categories. On the basis of in-sample fit, out-of-sample forecasts, and formal causality tests, this study demonstrates that the marketing mix decisions for ice cream influence the sales and market shares of ice cream toppings and frozen yogurt. As a check on the predictive validity of the model, model parameters, using 16-month data, predict behavior in the subsequent 3 months. 相似文献

The purpose of this paper is to investigate the impacts of infectious diseases including Avian Flu and severe acute respiratory syndrome (hereafter SARS) on international tourist arrivals in Asian countries using both single datasets and panel data procedures. An autoregressive moving average model together with an exogenous variables (ARMAX) model are used to estimate the effects of these diseases in each SARS- and Avian Flu-infected country, while a dynamic panel model is adopted to estimate the overall impact on the region of these two diseases. The empirical results from both approaches are consistent and indicate that the numbers of affected cases have a significant impact on SARS-affected countries but not on Avian Flu-affected countries. However, since the potential damage arising from the Avian Flu and subsequent pandemic influenza is much greater than that resulting from the SARS, the need to take the necessary precautions in the event of an outbreak of Avian Flu and pandemic influenza warrants further attention and action. Therefore, the empirical findings of this study could add to the knowledge regarding the relationship between tourism and crisis management, especially in so far as the management of transmissible diseases is concerned. 相似文献

市场潜能、人口密度与非农劳动生产率——来自中国地级面板数据的证据 总被引：1，自引：1，他引：1
本文基于样本期为1999—2004年的地级面板数据并运用动态面板数据的计量方法，对中国地级区域市场潜能、人口密度等经济地理因素与其非农业劳动生产率之间的关系进行了实证研究。结果表明，地级区域的市场潜能、人口密度等经济地理因素对其非农劳动生产率都存在显著为正的影响。而且，无论是从绝对弹性还是标准化弹性来看，地级区域市场潜能对其非农劳动生产率的影响都更大。 相似文献

近年来,伴随着我国旅游市场的不断扩大和旅游产业的转型升级,旅游产业呈现出明显的集群特点和趋势。文章从价值链角度,对旅游产业集群形成与发展的内在机理进行了分析研究。首先阐明了价值链视角下的旅游产业集群及其动力机制的内涵;其次提炼了旅游产业集群的产业价值链"四链"服务层次与空间价值链"四环"空间结构的特点,并分别采用上海与张家界两个案例进行了论证;最后总结了旅游产业集群两个维度下的动力机制,包括产业价值链延伸扩展机制及空间价值链优化配置机制,前者具体体现在集群要素产业高端化、集群要素产业融合化及集群要素产业均衡化,后者主要包括环内竞争性优化配置及环间合作性优化配置,而且产业价值链延伸扩展机制及空间价值链优化配置机制既是相互独立又相互补充的。通过以上研究,文章希望既在学术上完善对旅游产业集群动力机制的理论研究,又在实践中对我国旅游产业发展提供了有益的指导。 相似文献
