How important is the credit channel in the transmission of monetary policy in Mexico?

This article empirically examines the importance of the credit channel of monetary policy in Mexico for the period 2004–2013. We estimate a vector autoregressive (VAR) model to analyse the effects of a monetary policy shock on real output, and we also use a threshold VAR model to investigate asymmetric effects of contractionary and expansionary policies. The empirical results suggest that a contractionary monetary policy results in a fall in the supply of loans together with an increase in the spread between the lending and deposit rate. To the extent that some borrowers are dependent on bank loans for credit, the reduced supply of loans amplifies the effects of monetary policy on output associated with the traditional interest rate channel. Our results also suggest that the importance of the credit channel is larger for contractionary shocks than for expansionary shocks.     

Estimation of trade elasticities in the presence of trade barriers, multinationals and imperfect competition

Recent research highlights the role that multinational trading companies may play in impeding price transmission. In markets characterised by imperfect competition, an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper, we demonstrate the potential for market structure to affect price transmission and trade elasticities, and challenge the presumption that only government intervention can impact upon price transmission, with examples supporting why theory would suggest otherwise.     

工程建设施工现场中3G视频监控系统的研究与实现

随着建筑行业的飞速发展,施工现场的安全问题一直是工地管理工作的重中之重。网络技术的发展,使得视频监控系统运用到各行各业中。通过运用远程视频监控技术,实时对分布在各地的多个施工现场进行监管,既减轻了管理人员的工作量,又加强了建设行政主管部门以及施工和安全质量监督管理部门的监管力度。安全管理是建筑工地的重要管理环节,考虑到工地实际需求,本文针对传统视频监控系统实时性差、传输效率低、图像质量不稳定等缺点,对基于3G网络的工程建设施工现场远程视频监控系统进行研究和实现。文中介绍了3G网络的无线视频技术的优势及远程视频监控系统的功能特点,对施工现场3G远程视频监控系统的方案进行研究设计,并在某施工单位几个重点施工现场进行了试点安装,达到了预期效果,实现对施工现场实时监控。     

Social mobility and inequality in urban China: understanding the role of intergenerational transmission of education

China’s rapid economic growth since the late 1980s has been accompanied by great economic and social transformations, which have resulted in a sharp increase in income inequality. This article contributes to the literature of social mobility in China by examining the impact of parental education on the education of their children. Using the 1990 and 2000 Chinese Population Censuses, we employ nonparametric estimation strategies to provide a systematic investigation of intergenerational transmission of education in urban China. We find evidence of increasing parents–children educational correlations. Our results raise concerns regarding economic inequality in urban China as high intergenerational persistence of education is expected to be a barrier to equal opportunities in children’s education attainments and their future labour market outcomes.     

城市化与能源消费的动态相关性及其传导机制——基于1978年～2008年的实证研究

笔者依据1978年~2008年时间序列数据,实证分析了我国城市化与能源消费之间的动态相关性,并对城市化与能源消费之间的关联效应及其传导机制进行了考察。结果表明,我国城市化与能源消费存在协整关系,短期内存在误差修正机制;城市化对能源消费的影响主要是通过其规模效应和技术效应表现出来,而第三产业的节能效应尚不明显。

Transmission of the 2007–2008 financial crisis in advanced countries of the European Union

The aim of this paper is to identify the main factors responsible for the 2007–2008 crisis development and transmission across the 10 developed European Union (EU) countries. In order to achieve this objective, trade and financial linkages, crisis contagion from the United States and EU countries and countries' internal and external economic vulnerabilities are examined. The results of logistic regression model covering the period from 2002 to 2012 presented in this paper indicate that the transmission of the crisis occurred through contagion from the United States but also from other EU countries. Additionally, the empirical results confirm that high inflation, a decrease in the exchange rate, and a decrease in the US long-term interest rates increased the probability of the 2007–2008 financial crisis.
