集体钉住汇率制与地区金融稳定——兼评人民币汇率制度改革

20世纪90年代以来,东亚地区是国际金融比较动荡的地区之一。麦金农主张东亚各经济体实行“集体钉住美元”制度,以保证地区金融稳定。从理论和实践分析,集体钉住汇率制有其内在的稳定机制,也有内源性的动荡缺陷,稳定性和脆弱性同存。目前东亚各国和地区非正式的共同“软钉住美元”,有一定的合理性;但从长远看,这种集体钉住美元制度难以维持。当前人民币汇率改革不会影响东亚地区的金融稳定,维持国内金融稳定,才能防止地区金融动荡。     

A Markov switching analysis of contagion in the EMS

This paper applies the multivariate version of the Forbes and Rigobon (2002) contagion test, as proposed by Dungey et al. (2005a), to detect contagion effects in the Exchange Rate Mechanism (ERM) of the European Monetary System (EMS). Crisis and non-crisis observations are determined endogenously via a Markov-switching vector autoregression (MSVAR). We show that the MSVAR is suitable for this purpose, as it does particularly well in identifying the 11 realignments of the ERM. We examine whether Denmark’s rejection of the Maastricht Treaty and Italy’s competitiveness problems affected other EMS participants and find evidence for contagion.     

外汇市场压力问题的研究综述

本文从外汇市场压力的测度、外汇市场压力与货币政策、外汇市场压力与货币危机的识别与测度以及外汇市场压力与汇率制度四个方面总结了国外研究者对此的最新研究成果,从中我们发现外汇市场压力对于一国经济有着重要的影响,特别是在当前通胀预期下,外汇市场压力与我国资产价格波动和货币政策之间的相互作用过程值得我们去进一步研究。     

基于齐次马氏域变方法的中国股市价格泡沫检验

本文使用间接度量方法构建了股市价格泡沫的理论模型,得到了股市价格泡沫所满足的行为方程。在该理论模型下,本文利用Johansen协整检验方法从上证指数1996年1月到2007年12月的数据中剔除其理性价值成份,并进而建立马氏域变模型对其泡沫情况进行分析,结果表明上证指数价格泡沫主要集中于1996年3月到1997年6月、1999年全年以及2006年11月到2007年12月。此外,本文还通过对深证指数的分析检验了沪深两市股价泡沫的联动性,最后根据文章分析结果,提出了相应的政策建议。     

Phillips Curve Instability and Optimal Monetary Policy

Empirical evidence suggests the Phillips curve has flattened over the past few decades. To capture this feature of the data, I develop a framework where firms face a changing cost of price adjustment, which produces a Phillips curve with a slope coefficient that varies over time. To evaluate the implications for monetary policy, I construct the utility‐based welfare criterion where the relative weight on output gap deviations changes synchronously with the slope of the Phillips curve. The systematic component of the rule that implements optimal policy is constant under discretion and commitment.

Cooperative membership and farmers’ choice of marketing channels – Evidence from apple farmers in Shaanxi and Shandong Provinces,China

Cooperatives are established to improve farmers' production conditions, to increase their bargaining power and to enable them to benefit from modern value chains. In China, farmers are members of a cooperative for multiple reasons. Little is known on whether and how cooperative membership affects farmers’ choice of marketing channels. This paper examines determinants of farmers’ choice of marketing channels, especially how cooperative membership impacts upon this choice. Our analysis is based on survey data collected in 2015 among 625 apple growing farm households in the provinces Shaanxi and Shandong. We employ endogenous switching probit models to deal with potential endogeneity of membership in estimating the determinants of marketing channel choices. We find that cooperative membership has a positive impact on selling to wholesalers and a negative impact on selling to small dealers, but no significant impact on selling to the cooperative itself. As products sold through cooperatives generally comply with relatively stringent food quality and safety standards, these results imply that policies promoting cooperative members to sell their products through cooperatives are likely to have a significant impact on food quality and food safety in China.
