低通货膨胀与货币政策

持续15年的全球低通货膨胀,主要得益于各国成功的稳定化政策。低通货膨胀显示货币政策好处的同时,也给货币政策带来挑战。根据美日等国家的低通货膨胀经验,一个国家最好不要走向零利率的边缘,采取预防性的政策防止经济陷入通货紧缩至关重要。此外,需要正确认识货币政策的作用,货币政策长期的目标应该是为经济发展提供一个稳定的货币环境。美日国家预防低通货膨胀的经验对于中国宏观经济的平稳运行具有重要的借鉴意义。     

Optimal central bank transparency

Should central banks increase their degree of transparency any further? We show that there is likely to be an optimal intermediate degree of central bank transparency. Up to this optimum more transparency is desirable: it improves the quality of private sector inflation forecasts. But beyond the optimum people might: (1) start to attach too much weight to the conditionality of their forecasts, and/or (2) get confused by the large and increasing amount of information they receive. This deteriorates the (perceived) quality of private sector inflation forecasts. As a result, inflation is set in a more backward looking manner resulting in higher inflation persistence. By using a large scale panel data set on the transparency of central banks we find empirical support for an optimal intermediate degree of transparency at which inflation persistence is minimized. Our results indicate that while several central banks would benefit from further transparency increases, some already have reached the optimal level.     

Comment on: “When does a central bank’s balance sheet require fiscal support?” by Marco Del Negro and Christopher A. Sims

A central bank is insolvent if its plans imply a Ponzi scheme on reserves so the price level becomes infinity. If the central bank enjoys fiscal support, in the form of a dividend rule that pays out net income every period, including when it is negative, it can never become insolvent independently of the fiscal authority. Otherwise, this note distinguishes between intertemporal insolvency, rule insolvency, and period insolvency. While period and rule solvency depend on analyzing dividend rules and sources of risk to net income, evaluating intertemporal solvency requires overcoming the difficult challenge of measuring the present value of seignorage.     

When does a central bank׳s balance sheet require fiscal support?

Using a simple, general equilibrium model, we argue that it would be appropriate for a central bank with a large balance sheet composed of long-duration nominal assets to have access to, and be willing to ask for, support for its balance sheet by the fiscal authority. Otherwise its ability to control inflation may be at risk. This need for balance sheet support — a within-government transaction — is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank׳s balance sheet is merged with that of the rest of the government.

Market liquidity, asset prices, and welfare

This paper represents an equilibrium model for the demand and supply of liquidity and its impact on asset prices and welfare. We show that, when constant market presence is costly, purely idiosyncratic shocks lead to endogenous demand of liquidity and large price deviations from fundamentals. Moreover, market forces fail to lead to efficient supply of liquidity, which calls for potential policy interventions. However, we demonstrate that different policy tools can yield different efficiency consequences. For example, lowering the cost of supplying liquidity on the spot (e.g., through direct injection of liquidity or relaxation of ex post margin constraints) can decrease welfare while forcing more liquidity supply (e.g., through coordination of market participants) can improve welfare.     

Central banks’ preferences and banking sector vulnerability

According to “Schwartz's conventional wisdom” and what has been called “divine coincidence”, price stability should imply macroeconomic and financial stability. However, in light of the global financial crisis, with monetary policy focused on price stability, scholars have held that banking and financial risks were largely unaddressed. According to this alternative view, the belief in divine coincidence turns out to be benign neglect. The objective of this paper is to test Schwartz's hypothesis against the benign neglect hypothesis. The priority assigned to the inflation goal is proxied by the central banks’ conservatism (CBC) index proposed by Levieuge and Lucotte (2014), here extended to a large sample of 73 countries from 1980 to 2012. Banking sector vulnerability is measured by six alternative indicators that are frequently employed in the literature on early warning systems. Our results indicate that differences in monetary policy preferences robustly explain cross-country differences in banking vulnerability and validate the benign neglect hypothesis, in that a higher level of CBC implies a more vulnerable banking sector.

我国货币政策工具的演进、不足及改革方向

选择什么样的货币政策工具组合来确保货币政策目标的实现,必须与一国的货币政策调控方式相适应。本文通过回顾我国货币政策工具的演进过程,对比分析与西方发达国家的差异和不足,进而提出下一步货币政策工具的改革思路。     

Access policy and money market segmentation

Deviations between interest rates paid in the Swiss franc unsecured money market and the respective Libor rate are analysed for a period spanning the financial crisis. First, banks that have access to sources of secured central bank and interbank funding pay less than other banks. Second, foreign banks (not chartered in Switzerland) pay more than domestic banks. Third, both lines of segmentation are economically relevant but limited due to open access to sources of secured funding. Thus, access policy matters for monetary policy implementation and financial stability.     

试论我国货币政策工具选用问题

政策工具是货币政策体系的重要因素之一。西方发达国家的货币政策工具选用体现出显著的特点。研究这些特点对于解决当前我国货币政策工具选用问题是极其必要的 ,货币政策工具的选用不但受到经济体制、经济金融发展状况等因素的影响 ,而且与一国的经济传统是分不开的。当前经济金融运行的特点决定了我国货币政策工具选用的特殊性。     

中央银行货币政策工具变化评析

近年来,在全球经济一体化进程快速发展的背景下,以美国为代表的发达国家受次级抵押贷款危机影响,金融机构面临短期流动性不足的问题;以中国、韩国和印度为代表的新兴市场国家则出现流动性过剩的状况。为应对经济金融领域不断出现的新情况、新问题,保持中央银行货币政策的主动性和有效性,发达国家在充分运用传统货币政策工具的同时,适时引入了新的投放流动性的工具;新兴市场国家则不断拓展收回流动性的工具组合。本文简要分析了近来各国央行调整货币政策工具的背景情况,全面总结了发达国家及新兴市场国家货币政策工具变化的基本特点,并提出了央行货币政策工具调整中值得关注的问题。
