西方经济学界货币政策透明度理论研究述评

货币政策透明度是指非对称信息在政策制定者与其他经济主体之间的披露程度,它包括中央银行对政策相关信息的披露程度以及公众对政策信息的理解程度两层内涵.实践中,政策制定者选择多大程度的透明度主要取决于实际的经济环境和政策目标.从纯经济学的角度来讲,政策有效性是决定是否要提高货币政策透明度的唯一原因;而实践中无论是透明还是隐秘的货币政策,都有可能实现比较理想的调控结果.     

汇率目标制、货币目标制和通货膨胀目标制的比较及其在我国的应用的探讨

汇率目标制、货币目标制在各自的经济背景下都起到了稳定一国通货、稳定汇率从而稳定一国物价总水平、促进经济增长的作用。起始于20世纪80年代末期,通货膨胀目标制代替汇率目标制、货币目标制成为许多国家追逐长期价格稳定的一种货币政策新框架,在取得长期价格稳定和金融稳定上具有更多优点和灵活性。我国金融开放条件下货币政策调控面临国内货币需求不稳定,内部、外部经济不平衡,金融不平衡等问题,在货币目标制和汇率目标制难以实现货币政策有效调控的情况下,建议应对我国的货币政策调控方式做出调整,采用通货膨胀目标制的货币政策框架。     

中国货币政策目标制的选择——基于开放经济体的实证

本文使用开放经济下的新凯恩斯模型实证分析了开放经济体中不同的货币政策目标制。结果表明,面对国内利率政策、技术、国外通货膨胀、国外产出和国外实际利率冲击时,由灵活通货膨胀目标、资本自由流动和完全浮动的汇率构成的货币政策目标体系能够有效吸收冲击,减缓经济波动。相比而言,严格通胀目标制无法有效吸收国内外冲击,所以我国在开放经济下选择货币政策目标时,并不一定要选择严格通货膨胀目标,可以选择一些灵活通货膨胀目标的政策框架。此外,能够有效吸收各种冲击的灵活通胀目标、资本自由流动和完全浮动汇率制组成的目标体系也为我国货币政策和汇率制度改革提供了方向。     

On the Edge of Buying: A Targeting Approach for Indecisive Buyers Based on Willingness-to-Pay Ranges

Targeting the “right” consumers is a core part of marketing. Whereas existing techniques to identify these consumers use demographic or psychographic variables or behaviors such as response probabilities, a proposed new targeting approach builds on consumers’ incremental responses to identify them by their willingness-to-pay (WTP) ranges. These WTP ranges reveal a consumer as a definite buyer, a definite non-buyer, or an indecisive buyer. The proposed theoretical framework indicates that indecisive buyers offer the highest incremental responses to targeted marketing mix activities and thus should be the most preferred targeting group. A sequence of three laboratory experimental studies validates the proposed approach for targeted price discounts and non-price tactics. In addition, a large-scale field experiment involving a consumer engagement campaign that includes observed purchase behavior demonstrates the high external validity and applicability of this approach.     

信息不完全、通货膨胀目标制与货币政策声誉:跨国经验

20世纪90年代以来通行的通货膨胀目标制被认为是极具透明性、灵活性的货币政策框架，受到很多国家的推崇。本文验证通货膨胀目标制是否有助于建立货币政策声誉，构建一个基于信息不完全基础上的动态预期形成模型，通过对通货膨胀目标制能否引起结构性变化的七个发达国家的实证研究，发现政策声誉的建立是一个学习过程。通货膨胀目标制实行的时间越长，该政策对降低通货膨胀率，实现经济稳定增长越有效。     

Countercyclical safety nets for the poor and vulnerable

Relatively little is known about how government safety net programs insure against low consumption and stabilize asset bases, compared to what is known about their role in transferring income. The insurance function requires a flexible budget that can be scaled up rapidly to meet unanticipated circumstances. Safety nets serving an insurance function also differ from other transfer programs in their targeting; they need to determine transitory need rather than more chronic correlates of poverty. Moreover, insurance safety nets need a more flexible implementation strategy than do more permanent programs. This paper reviews these issues from the perspective of low income countries.     

Piloting a systematic framework for public investment in regional natural resource management: Dryland salinity in Australia

The Salinity Investment Framework (SIF3) is designed to help environmental managers make better policy decisions about protecting key assets under threat of dryland salinity, a major degradation problem in Australia. This study reports results from applying SIF3 in partnership with two regional organizations (in the states of Victoria and Western Australia) with contrasting institutional powers and structures. We also engaged relevant policy makers with a view to influencing national policy. Available knowledge, science, and data were used to develop region-specific recommendations for public investment in salinity management. SIF3 proved easy to apply, requiring minimal changes from its original version. Establishing trust and credibility with stakeholders was extremely important. More time was required to be spent on communicating what SIF3 was and what it would mean for stakeholders than in applying it in the catchments. In both regions, recommendations included making a clear distinction between localized assets (such as a particular wetland) and dispersed assets (such as agricultural land as a whole); more targeted investment in spatially identified localized assets; using a broader range of policy tools; basing recommendations on the levels of public and private net benefits; anticipating the adoptability of sustainable land-management practices; and formally integrating relevant scientific, economic and social information with community values. The differences between current action and recommendations were significant in both regions, particularly in Victoria. As a result of our work both regions have decided to implementing a similar asset-based approach covering various environmental threats in addition to dryland salinity. The research indicates that it is feasible to use decision frameworks such as SIF3 to improve the rigour of decision making by community-based environmental management organizations. A broader range of policy tools are needed for dryland salinity, with less reliance on extension and small grants, and more emphasis on intervention around key assets and investment in technology development. We have influenced policy makers to some extent at state level and nationally through discussion of SIF3 in a national inquiry, preparation of a policy paper for peak multi-government policy committees, briefings and provision of advice on policy design. Despite this, achieving significant policy change at the state and national levels remains difficult for a number of reasons. Governments give limited signals to environmental managers to achieve environmental outcomes, being more concerned with community participation objectives and political considerations. We hope for significant policy change with increased scrutiny about sound decision making and public accountability.     

Poverty-decreasing indirect tax reforms: Evidence from Tunisia

This paper proposes a methodology to identify revenue-neutral directions for poverty-alleviating tax reforms. The search for such poverty-reducing tax reforms is done “robustly” over broad classes of poverty measures and poverty lines. The methodology, which is illustrated using data from Tunisia, is of significant policy interest given the widespread use of commodity subsidization and taxation in developing and developed countries alike. The results suggest that Tunisian poverty could be decreased robustly by following reform directions that are often at odds with frequently-heard views. They also highlight the importance of stating clearly under which set of ethical criteria the desirability of potential indirect tax reforms is assessed. JEL Code D12 ⋅ D63 ⋅ H53 ⋅ I32 ⋅ I38     

通货膨胀目标制度在我国实施的可行性分析

20世纪90年代以来,由于通货膨胀目标制(Inflation Targeting,以下又简称通胀目标制)被越来越多的国家采用,使得通胀目标制成为近年西方货币经济学领域最热门的研究课题之一。从传统的以控制货币供应量为主的货币目标法(Monetary'Targeting)和以稳定汇率为主的汇率目标法(Exchange rate Targeting)到明确公布通货膨胀目标的通胀目标制是一个货币政策方面的重大转变。本文主要分析了我国实施通胀目标制的可行性,并提供相关的政策建议。
