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. 相似文献

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. 相似文献

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.

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. 相似文献

Noisy chaotic dynamics in commodity markets 总被引:2,自引:1,他引:2

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003 相似文献

金融发展和经济增长: 来自中国的实证检验 总被引:8,自引:0,他引:8
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. 相似文献
