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.     

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。     

The evolution of the monetary transmission channels in Turkey: evidence from a TVP-VAR model

This article investigates the evolution of the monetary transmission mechanisms in Turkey for the period from January 1986 to December 2016. To this aim, the impacts of monetary variables on the prices and economic activity are investigated with a time-varying vector autoregressive model based on. The evidences from the time-varying responses indicate that the adoption of inflation targeting policy has markedly affected the functioning of transmission channels. The results also suggest that local and global financial crises may magnify the impact of monetary policy shocks on the overall economy.     

货币传导异质性与实体经济流动性配置的“马太效应”

货币政策支持实体经济高质量发展的关键在于疏通货币政策传导机制,引导流动性进入重点领域和薄弱环节,因此货币资金的配置效率至关重要。本文基于交互效应面板分位数回归,测度货币政策对实体企业流动性的异质性效应。研究发现:在样本期内,实体经济流动性配置陷入了资金越充裕的企业越易于获得融资,越易于获得融资的企业资金越充裕的窘境。这种流动性配置的“马太效应”具体表现为,货币政策对尾部企业的支持力度不及头部企业的一半;虚拟经济对尾部企业的“分流效应”高达头部企业的3倍,从而强化了流动性配置的失衡。因此,当前密集出台的一系列普惠政策有助于提升流动性配置效率,进一步完善调控模式的关键在于健全现代化金融体系,增强货币政策的靶向性和针对性。     

Sovereign risk and belief-driven fluctuations in the euro area

Sovereign risk premia in several euro area countries have risen markedly since 2008, driving up credit spreads in the private sector as well. We propose a New Keynesian model of a two-region monetary union that accounts for this “sovereign risk channel.” The model is calibrated to the euro area as of mid-2012. We show that a combination of sovereign risk in one region and strongly procyclical fiscal policy at the aggregate level exacerbates the risk of belief-driven deflationary downturns. The model provides an argument in favor of coordinated, asymmetric fiscal stances as a way to prevent self-fulfilling debt crises.     

Deconstructing credibility: The breaking of monetary policy rules in Brazil

Can political interference deconstruct credibility that was hardly-earned through successful stabilization policy? We analyze the recent switch in the conduct of monetary policy by the Central Bank of Brazil (BCB). Brazil is the largest Emerging Market Economy to formally target inflation, having adopted the Inflation Targeting (IT) regime in 1999. In the early years of IT, the BCB engaged in constructing credibility with price setting agents and succeeded to anchor inflation expectations to its target even under adverse conditions such as exchange rate crises. We argue that this effort to maintain IT rules-based policy ended in 2011, as a new country president and BCB board came to power. We then discuss the consequences of this credibility loss. Our main results can be summarized as follows: (i) we provide strong empirical evidence of the BCB’s shift toward looser, discretionary policy after 2011; (ii) preliminary evidence suggests that this shift has affected agents’ inflation expectations generating social and economic costs.     

Sunk costs and travel cancellation: Focusing on temporal cost

Tourism products differ from ordinary retail products in terms of the spatial and temporal separation between the purchase and experiencing the product. Despite its importance, temporal separation has not drawn much attention in tourism research. The main objective of this study is to understand the effects of temporal sunk costs on potential travelers' cancellation intentions, in addition to monetary sunk costs. The results of this study suggested the possibility that temporal costs can be converted into monetary costs, but the conversion relationship may not be linear. This study also indicated that travelers' intentions to cancel a travel product decreased as the temporal and monetary sunk costs increased. Further, prior experience moderated the relationship when temporal sunk costs were involved, suggesting that repeat visitors' intentions to cancel their reservations are more influenced by temporal sunk costs than first-time visitors. Further discussion and implications are provided in the main body of this paper.     

The cost of deviating from the optimal monetary policy: A panel VAR analysis

Exploiting the panel VAR GMM estimator's features, macroeconomic country factors are combined with micro-economic bank data to test for the risk taking channel in the Euro Area. According to prior expectations based on an extended DSGE model, the analysis demonstrates that the monetary policy incentives bank risk taking by increasing the bank leverage, but it is not able to influence the level of credit risk. However, deeper investigations indicates the Taylor gap adds to the bank risk appetite in all its forms, while regarding the reactions to target variables, movements in the interest rate smooth the bank risk.     

Evaluating monetary policy under preferences with zero wealth effect: A Bayesian approach

Both real and monetary macro models have parallely exploited the potential for various preferences in accounting for empirical facts. This paper brings the two literatures together by estimating time non-separable preferences with habit formation in consumption that nests several commonly used preferences. In the absence of wealth effects and external habits, these preferences fail to generate observed inflation inertia and output persistence after a monetary policy shock. Furthermore, the data strongly rejects these preferences in favor of preferences with external habits. An alternative solution is to include habit adjusted intermediate wealth effect preferences which are able to simultaneously generate sluggish responses of the variables to a monetary policy shock and fit the data better.
