贸易顺差、冲销操作和货币政策效应的非对称性

文章利用＂G—R＂模型和结构向量自回归模型,实证分析我国货币政策的独立性和非对称性,通过我国汇改前后的比较得出,汇改之前货币政策独立性小于汇改之后,但汇改后,为保持汇率稳定而进行的冲销操作在很大程度上削弱了我国货币政策的独立性。通过江苏、山东和四川三省的实证分析得出,货币政策效应存在明显的区域差异。     

Scarcity of safe assets,inflation, and the policy trap

A goal of this paper is to make sense of the seemingly puzzling behavior of interest rates and inflation – and the role of central banks in that behavior – during and after the Great Recession, particularly in the United States. To this end, we construct a model in which government debt plays a key role in exchange, and can bear a liquidity premium. If asset market constraints bind, then there need not be deflation under an indefinite zero interest rate policy (ZIRP). Further, ZIRP may not be optimal under these circumstances. A Taylor-rule central banker could be subject to a ZIRP trap and persistently undershoot target inflation. As well, a liquidity premium on government debt creates additional Taylor rule perils, because of a persistently low real interest rate. We make a case that this is the key policy predicament currently faced by many central banks in the world.     

Reputation,risk-taking,and macroprudential policy

This paper examines the role of macroprudential capital requirements in preventing inefficient credit booms in a model with reputational externalities. In our model, unprofitable banks have strong incentives to invest in risky assets when macroeconomic fundamentals are good in order to avoid the stigma of being assessed as low ability by the market. We show that across-the-system countercyclical capital requirements that deter such gambling are constrained optimal when fundamentals are neither extremely weak nor extremely strong.     

Macroprudential policy and imbalances in the euro area

Since its creation the euro area suffered from imbalances between its core and peripheral members. This paper checks whether macroprudential policy applied to the peripheral countries could contribute to providing more macroeconomic stability in this region. To this end we build a two-economy macrofinancial model and simulate the effects of macroprudential policy (regulating the loan-to-value ratio) when the core and the periphery are exposed to asymmetric shocks. We find that macroprudential policy is able to substantially lower the amplitude of credit and output fluctuations in the periphery. However, for the policy to be effective, it should be decentralized. Very similar conclusions hold when welfare is considered as the optimality criterion.     

Ethical dilemmas: Teaching futures in schools

Educational policy is implicitly futures oriented, yet in most instances fails to engage learners with explicit futures tools and concepts at a school level. Futures studies in education, or futures education has the potential to reposition learning as purposeful and mobilizes the lives of participants by connecting the curriculum of schools with the multifaceted futures of learners. This is a complex task within the tensions often existing between: the cultural role of a school, the expectations of a society, the expertise of teachers, and the increasingly diverse needs of learners (Bateman, 2012). It is between the tensions of these things that the ‘ethical’ issues of what is taught, or omitted as content in a classroom and the consequences of these choices are evident.This paper highlights ethical and moral dilemmas, as they were apparent in two futures education projects. In the first study, the teachers discuss the inherent limitations of offering a broader and more futures oriented curriculum. In the second study, teachers reflect upon their students’ anxiety with regards to futures images as they are interrogated within a curriculum study. Each of these studies highlights the ethical challenges that arise, when possible, preferable and probable futures are developed as part of learning in school settings, which are culturally and demographically diverse.Tirri and Husu (2002) highlight the ethical dilemmas, which emerge in classrooms around the world, based on conflicts in values and competing intentions between key stakeholders. In the studies which contribute to this discussion, there is evidence to suggest that futures thinking causes conflict within an individual's perception of how the world should be, or their worldview as a result of futures imagining which goes beyond what is taken for granted, or is an assumed future eventuality. In the same way, Carrington, Deppeler, and Moss (2010) argue that all curriculum choices about what is taught (or not taught) in a classroom reflect an ethical decision made by a teacher, with regards to what is foregrounded for learning and what is omitted.It is crucial to re-examine the role of a school in educating students for their futures, as opposed to educating students with an aim of furthering governmental agendas. More significantly, however, as this paper highlights, it is exploring the boundaries of what is acceptable or unacceptable, appropriate or inappropriate to teach in a classroom, given the changing diversities of schools and education systems throughout the world.     

基于银行流动性管理视角的宏观审慎与货币政策协调研究

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。
