  我院教师戴玉雯博士与其合作者的学术论文Nominal GDP Targeting and Central Bank Conservativeness”被SSCI来源刊Bulletin of Economic Research接受发表。

  在现有的货币经济学的文献中,存在“通货膨胀偏差”(inflationary bias) 的结果,该结果预测通货膨胀率将在可自由支配的货币政策(discretionary monetary policy)下偏向更高水平,这是由于中央银行在制定和执行货币政策时存在时间不一致的问题(time-inconsistency problem)。但在基于规则的货币政策(rule-based monetary policy)下,已确定的名义定锚(nominalanchor)可以消除这种“通胀偏差”。在这篇论文中,两位作者研究了货币政策执行的合适目标,以揭示关于货币政策制定中规则与自由裁量权的适当性的争论。在此背景下,作者研究了名义GDP目标制(nominal GDP targeting),这是一种基于规则的货币政策制度(rule-based monetary policy)。作者通过数学模型证明根据中央银行的保守程度,价格和实际GDP目标的不同组合的选择仍然可能导致“通胀偏差”,并且还存在“通缩偏差”(dis-inflationary bias)的可能性。因此,中央银行在选择货币政策的名义锚时,应该考虑名义GDP目标制中固有的价格偏差,并将其与名义GDP目标制适应不利冲击的优势相平衡。

Abstract  

In the literature on monetary economics, there is the “inflationary bias” result which predicts that the rate ofinflation will be biased towards a higher level under discretionary monetary policy than under a rule-based policy regime. It is established that a credible nominal target can eliminate this“inflationary bias”. In this paper, we examine the case of nominal GDP targeting, which is a rule-based monetary regime. Depending on the degree of conservativeness by the central bank, we show in a stylized model the choice of different combination of inflation and real GDP targets can still result in an“inflationary bias”, and there also exists the possibility of a“dis-inflationary bias”.

Key words: monetary policy, nominal GDP targeting, central bank, conservatism, inflationary bias.

JEL classification: E52, E58.
