European policy and markets: Did policy initiatives stem the sovereign debt crisis in the euro area?

We investigate how European policy initiatives influenced market assessments of sovereign default risk and banking sector fragility during the sovereign debt crisis in four adversely affected countries — Portugal, Ireland, Spain and Italy. We focus on three broad groups of policies: (a) ECB policy actions (monetary and financial support), (b) EU programs (financial and fiscal rules as well as financial support in crisis countries), and (c) domestic austerity programs. We measure immediate market impact effects: what policies changed risk perceptions, using CDS spreads on sovereign bonds and banks in this assessment. We employ dynamic panel and event study methodologies in the empirical work. We find that a number of programs initially stabilized sovereign and bank bond markets (e.g. Outright Monetary Transactions program), although announcement and implementation impacts on markets differed in some cases (e.g. second Covered Market Bond Program). Actions designed to shore up sovereign markets often lowered risk assessments in bank bond markets and policies designed to ensure safety and soundness of the European banking system in some cases significantly impacted sovereign debt markets. Finally, a number of policies designed to stabilize markets had surprisingly little immediate impact on either sovereign or bank bond market risk assessments.     

我国利率传导机制有效性：基于货币幻觉的实证研究

本文将货币幻觉纳入投资函数和储蓄函数．并利用2000年9月到2006年8月的月度数据，经过HP滤波处理后采用Almon多项式分布滞后模型估计出投资函数和储蓄函数。我们发现在考虑货币幻觉的情况下，一方面，投资者存在货币幻觉且利率对投资有很好的调控作用，另一方面，储户不存在货币幻觉并且利率对储蓄的调控作用不明显，其原因可能是社保制度的缺位增强了储户的安全性动机以及投资渠道的不完善导致了储蓄的利率刚性。     

浅析信用建设对民营企业的重要性

民营企业目前面临着二次创业的危机，其中信用引起的融资难是一个很重要的原因。本文着重分析了民营企业信用缺失的状况及原因，以及信用机制的建立对民营企业发展有着至关重要的影响。指出由于我国金融制度安捧的不合理、资本市场上信息不对称、民营企业自身规模的限制，导致的信用一融资传导机制的不畅通。并针对性的提出了一系列配套建议。     

信息传导与美元/人民币外汇掉期的定价

人民币外汇衍生产品中,外汇掉期比远期具有更重要的市场地位,然而其在中国的理论定价却失效。从信息传导角度看,指示性合约对市场总体定价的影响更加突出。本文研究美元/人民币外汇掉期的指示性合约,创造性地构建合约影响因子指标,衡量各外汇掉期合约的市场影响力,进而发现3个月期合约是指示性合约。本文还确定了各合约的主要信息来源。文章研究成果可为投资者、监管层和政策制定者提供有价值的决策依据。     

中国上市企业投资的资本成本敏感性估计

企业投资对资本成本的敏感性是识别货币政策利率传导渠道是否畅通以及IS曲线斜率的重要参数。本文基于新古典投资模型框架,使用2004-2017年中国上市公司非平衡面板数据,估计了中国上市企业投资的资本成本敏感性,并侧重检验了融资约束对企业投资资本成本敏感性的影响。估计结果显示:(1)上市企业投资的加权资本成本弹性显著为负,且已具有较强敏感性(长期弹性系数为-0.16～-0.27),价格型货币政策工具的传导条件在上市公司投资环节正逐渐具备 ;(2)对加权资本成本的结构性估计显示,企业投资主要对债务资本成本的变动较为敏感且系数显著为负,而对股权资本成本的变动敏感程度较低且不稳定;(3)与传统观点相反的是,非国有控股上市企业投资的资本成本敏感性显著低于国有控股上市企业;较强的融资约束是导致非国有控股上市企业投资的资本成本敏感性较低的重要原因,应重视民营经济面临较强的融资约束对价格型货币政策工具传导机制的负面影响。本文的研究为中国货币政策框架的转型以及价格型货币政策传导机制的有效性提供了微观经验证据的支持。     

用电流传输器构成的二阶有源滤波器的研究

本文以电流传输器[CCⅡ^ ]为基本电路元件，用系统模型法对构成的二阶有源滤波器进行了理论分析，并推导了二阶通用滤波器的传递函数。     

外源型经济发达地区货币政策传导探讨——以东莞为视角

本文对东莞地区的货币政策传导进行分析后发现,外资企业游离于国内信贷市场之外、外资企业内部转移定价方式和"哑铃型"人口收入结构分别弱化了外源性经济发达地区货币政策对投资需求、净出口需求和消费需求调控的传导,认为应该在加强跨境资金流动监控的同时,通过推进产业转型升级和发展民营经济来增强地区经济的内生性,从而改善外源型经济发达地区的货币政策传导.     

基于关联数字矩阵的科技创新政策传导路径研究

科技创新政策传导系统是一个动态复杂性反馈系统，基于关联数字矩阵对政策传导系统路径进行量化研究，综合考虑政策输入变量—政策过程变量—政策输出变量的整个过程，建立科技创新政策传导模型，结合关联数字矩阵反馈复杂性、系统动力学和政策科学，构建科技创新政策传导系统因果关系图，并根据政策工具的划分解析人才、税收、研发、政府采购、服务外包5类政策的作用路径。研究发现：①科技创新政策传导系统存在87条正反馈环，无负反馈环，其中主导反馈环45条；②通过关联数字矩阵最终得到14条政策独立主导传导路径并明确各个路径的数量、长度和极性，其中，8条路径都存在延迟效应；③人才激励在政策调控促进创新和发展中占比较大，具有重要地位，服务外包政策紧随其后，两类政策工具对政策调控效果具有直接显著作用，而研发补贴政策对目标的调控最缺乏活力。     

Pricing flexibility under rate-of-return regulation: Effects on network infrastructure investment

When a commodity market relies upon a regulated network service industry—e.g., telecommunications, electricity, or natural gas transmission—economic efficiency in that commodity market is a crucial consideration for regulatory design. This is because insufficient infrastructure investment relative to network demand results in congestion. The extraction of associated rents has distortionary effects on commodity spot market prices. Greater regulatory flexibility in network pricing can alleviate such issues by cultivating the incentives needed for stakeholders to invest in transmission capacity. To illustrate this effect I derive and numerically solve stylized optimality conditions for access and usage prices for a gas pipeline operator under alternative regulatory models. My results have general implications for regulation in network infrastructure industries, as energy and telecommunications markets are expected to expand considerably over the coming decades.     

The Credit View, Old and New

Recent writings in the so-called 'credit view' focus on binding finance constraints of macroeconomic activity which arise from the incomplete substitutability of bank credit and from changes in borrowers' net worth. They criticize the standard approaches in the 'money view' for not taking full account of the observable effects of monetary restrictions on real activity. In this paper, the 'new credit view' is contrasted with older macroeconomic theories that placed special emphasis on the banks' systemic potential to expand credit beyond planned saving. The comparative discussion of the underlying arguments about bank behaviour, about the non-neutrality of credit money, and about the transmission of monetary policy impulses reveals some shortcomings in the new view. History helps, moreover, to set the conventional confrontations of the 'credit view' and the 'money view' in perspective. JEL-classification: B22, E32, E44, E51, E52
