国防支出与经济增长的关系研究——基于中国、日本、韩国的实证分析

文章使用Enders-Siklos不对称门槛共整合模型,检定中国、日本及韩国的经济增长与国防支出之间不对称的长期均衡关系,并以门槛误差修正模型(T-ECM)探讨三国的经济增长与国防支出之间领先-落后的因果关系,以及长期均衡关系调整的不对称性。经研究发现:第一,采用Enders-Siklos不对称门槛共整合检定,发现中国、韩国的经济增长与国防支出之间存在不对称的共整合关系,日本的经济增长与国防支出之间具有对称的共整合关系;第二,由Granger因果关系检定,发现韩国、中国的经济增长与其国防支出之间存在有不对称的长期性领先-落后关系,日本的经济增长与国防支出不存在长期性因果关系;第三,由Granger因果关系检定,发现中国的经济增长与国防支出之间存在短期的双向因果互动关系,而日本、韩国则是经济增长单向领先其国防支出。

Effective Nonverbal Communication Techniques

Developing effective marketing strategies for profes- sional service firms presents many unique challen es and is an im- portant area of practice development that many &ns often wer- look. Professional service firms ossess very distinctive P characteristics which differentiate them rom other service firms and require specialized marketing strategies. The purpose of this article is to assist practitioners in their efforts to develop promotional strat- egies which will enhance their firm's professional image and in- crease the firm's ability to engage new clients. These strategies arc aimed specifically at certified public accountants, lawyers, archi- tects, and other professionals.     

Optimal tariffs,optimal taxes and economic development

Cross-section and time-series data suggest that nations substitute income taxes for tariffs as they develop. This paper confronts the data within the context of a two-country open-economy endogenous growth model in which public expenditure is financed by an optimal tariff and income tax. When the latter is subject to administrative costs, the model predicts that the government will optimally substitute the income tax for the tariff as output rises along the transition. The model is calibrated and a simulation yields time paths for the shares of total government revenue derived from the tariff and the income tax that are consistent with the data.     

China＇s Economic Growth： International Spillovers

China's economic development since 1978 is one of the most significant events in recent history. Many aspects of this development have been extensively analyzed in the published literature. However, the implications of China's growth for other countries have been relatively neglected. The present paper attempts to fill this gap in the literature. The paper first presents some facts on China's role in the world economy, and then measures the impact of China's growth on growth in the rest of the world in both the short term and the long term. Short‐run estimates based on vector autoregression and error correction models suggest that spillover effects of China's growth have increased in recent decades. Long‐term spillover effects, estimated through growth regressions based on panel data, are also significant and have extended in recent decades beyond Asia. The estimates are robust to the effects of global and regional shocks, changes in model specification, and sample period.     

Time-varying linkages between tourism receipts and economic growth in South Africa

The causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the sensitivity of the causal link, we use rolling window and time-varying coefficient estimation methods to analyse the parameter stability and Granger causality based on a vector error correction model (VECM). When applied to South Africa for the period 1960–2011, the findings are as follows: results from the full-sample VECM indicate that there is no Granger causality between tourism receipts and GDP, while the findings from the time-varying coefficients model based on the state-space representation show that tourism receipts have positive-predictive content for GDP for the entire period, with the exception of the period between 1985 and 1990. Full-sample time-varying causality tests show bidirectional strong causality between tourism receipts and GDP.
