Are imports and remittances cointegrated for the Central and Eastern European countries?

In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.     

COVID-19, stock market and sectoral contagion in US: a time-frequency analysis

We assess the conditional relationship in the time-frequency domain between the return on S&P 500 and confirmed cases and deaths by COVID-19 in Hubei, China, countries with record deaths and the world, for the period from January 29 to June 30, 2020. Methodologically, we follow Aguiar-Conraria et al. (2018), by using partial coherencies, phase-difference diagrams, and gains. We also perform a parametric test for Granger-causality in quantiles developed by Troster (2018). We find that short-term cycles of deaths in Italy in the first days of March, and soon afterwards, cycles of deaths in the world are able to lead out-of-phase US stock market. We find that low frequency cycles of the US market index in the first half of April are useful to anticipate in an anti-phasic way the cycles of deaths in the US. We also explore sectoral contagion, based on dissimilarities, Granger causality and partial coherencies between S&P sector indices. Our findings, such as the strategic role of the energy sector, which first reacted to the pandemic, or the evidence about predictability of the Telecom cycles, are useful to tell the history of the pass-through of this recent health crises across the sectors of the US economy.     

The Small Business Capital Market Behavior in Athens Stock Exchange

Financing small and medium enterprises (SMEs), especially business investments and growth, is a composite and particular complicated affair in the Greek entrepreneurial reality. This paper examines the significance of secondary capital markets, as an alternative source of financing small-medium enterprises’ new entrepreneurial plans. Cointegration technique is applied to test the relationship between the secondary capital market and the dominant sectors in Athens Stock Exchange (ASE). Causality tests are also used to provide evidence on the existence of interdependence between the cointegrated series. The results indicate that there is significant uni-directional causality between primary and secondary capital market in Greece, enhancing us to suggest valuable policy implications.      

The Structural Relation Between Mortgage and Market Interest Rates

This paper analyzes the dynamic relationship between primary and secondary mortgage markets and the short-term and long-term market interest rates. Using a series of monthly data on fixed rate mortgage rates and GNMA rates, we explore the dependence and speed of adjustment in these primary and secondary mortgage rates to each other as well as to the long and short-term government rates. The results indicate that residential mortgage rates in general, appear to follow the long-term rate and are not very sensitive to movements in the short-term interest rate.     

中国和新加坡产业内贸易与规模经济关系的协整分析

中国和新加坡产业内贸易与规模经济存在着一种长期的均衡关系,新加坡生产企业的规模经济对产业内贸易的推动作用大于中国,中国和新加坡生产企业的规模经济与产业内贸易存在单向因果关系,即规模经济促进产业内贸易.     

汇率波动率与中国对主要贸易伙伴的出口

本文研究汇率波动率对中国向三个主要贸易伙伴美国、欧盟和日本出口的影响。通过协整检验,误差修正模型和Granger非因果检验等方法估计变量间长短期的关系。研究表明,中国向美国和欧盟的实际出口与实际汇率波动率存在长期显著的负相关关系,而中国向日本的出口与汇率波动率无关。短期内汇率波动率只影响中国向美国的出口,对向欧盟和日本的出口没有影响。     

国内外黄金市场的关联研究

本文利用Johansen协整检验、误差修正模型、Granger因果检验以及冲击反应分析对国内、国际市场黄金现货价格的动态联系进行了实证研究,研究结果显示:上海黄金交易所与伦敦黄金市场的黄金价格之间存在长期均衡关系,两个市场上的黄金价格相互影响、相互作用,且伦敦市场对上海市场的影响力大于上海市场对伦敦市场的影响力。     

上海和伦敦期铜价格谐整和引导关系的实证研究

简单介绍谐整性和引导性理论以及谐整性和引导性的检验方法，并根据谐整性和引导性的检验方法，对伦敦金属交易所和上海金属交易所1998年8月2日到2002年12月21日间共577天的期铜价格进行了实证分析，即检验两市场间是否存在谐整和引导关系，以期为期货交易的实际操作和我国期货市场的发展提供决策依据。     

金融发展和经济增长: 来自中国的实证检验

利用时间序列框架内的格兰杰因果分析、协整技术和向量误差修正模型,本文评价1978-2005年间金融发展与经济增长间的数量联系.实证分析发现,控制政府支出和贸易开放度后,金融体系资金运用和金融深度都是经济增长的格兰杰原因,且都与经济增长正相关.而且,基于自回归分布滞后边界检验和向量误差修正模型,本文也实证检验中国股票市场发展与经济增长关系:分别控制政府支出和贸易开放度后,金融市场总融资额是经济增长的原因,而经济增长是股票市场周转率的格兰杰原因.文章最后给出实证结论和简短的政策建议.     

市场化与经济增长:一个短期的因果关系检验
