Endogenous innovation under New Keynesian dynamic stochastic general equilibrium model

This paper constructs an endogenous growth model using the framework of New Keynesian dynamic stochastic general equilibrium models. We incorporate the Schumpeterian approach that generates seemingly sticky prices and reinterpret the Calvo mechanism from the perspective of Bertrand competition and successful entrepreneurs. Our results demonstrate that both positive productivity shocks and endogenous innovation have a negative effect on subsequent endogenous innovation. These self-destructive effects of endogenous innovation might account for the IT productivity paradox and productivity slowdown seen in advanced countries. Furthermore, it is shown that there are both neutral and non-neutral properties of monetary policy shocks. They are neutral in terms of the growth effect, but non-neutral in terms of the level effect. In particular, expansionist monetary policies are desirable to facilitate endogenous innovation.     

Monetary and fiscal policy interactions in a post Keynesian open-economy model

Using a post Keynesian model, this study aims to analyze the stabilizing role of fiscal and monetary policies in an open economy with a managed exchange rate regime. The real exchange rate is modeled as an endogenous variable and inflation explained using the conflicting claims approach. The dynamic properties of macroeconomic equilibrium are evaluated in different regimes of fiscal and monetary policies. The main result of this study suggests that the preferred policy regime is the one in which economic authorities are complementary and fiscal policy plays an explicitly active role. In this regime, the fiscal policy must commit to the target for the rate of capacity utilization and the monetary authority must commit to the inflation target.     

中国货币政策的福利损失及中介目标的选择——基于新凯恩斯DSGE模型的分析

文章运用新凯恩斯框架下的DSGE模型对中国货币政策的福利损失进行分析,研究表明:(1)名义利率对通货膨胀的反应越是敏感,则福利损失越小,因此,货币当局应该充分利用利率政策稳定价格水平;(2)名义利率对产出的反应越是敏感,则福利损失越大,因此,货币当局不宜运用利率政策影响经济增长速度;(3)利率平滑对福利的影响不大,货币当局的利率政策应该直接针对通货膨胀,而不应该追求利率本身的稳定;(4)在一定条件下,不同的利率政策规则造成的福利损失差别不大,货币当局可以从便利的角度出发,根据上期的通货膨胀率和产出水平来设定当期的名义利率;(5)与利率变动相比,货币供应量的变动造成福利损失更大,因此,货币政策的中介目标应该逐步由货币供应量转向利率。     

新凯恩斯主义总需求理论的微观基础——一个基本模型及其在货币政策中的应用

宏观经济学正在迈向新一次综合.在这个进程中,一些前沿经济学家为总需求理论构建了坚实的微观基础,使其成为新新古典综合框架的一块基石.它与同样建立在微观基础上的总供给理论相结合,就成为当前主流宏观经济学进行货币政策分析的标准工具.利用这个工具,经济学家对货币政策的研究得出了很多富有启发性的结论.本文梳理了总需求理论的上述新近发展,并讨论它在货币政策中的一些应用.特别地,本文的分析表明,这些应用对于中国的货币政策操作具有重要的借鉴意义.     

Capital Flows to Asia: The Role of Monetary Policy

Monetary policy played an important role in the Asian experience with capital inflows. Central banks used monetary policy to contain the threat of overheating, but the resulting increases in interest rates attracted additional inflows. Empirical measurement of these links shows that tight monetary policy was an important source of inflows to Indonesia and Thailand in recent years, and that the independence of monetary policy decreased during the inflow period.     

Monetary and fiscal policy interactions in the post-war U.S.

A New Keynesian model allowing for an active monetary and passive fiscal policy (AMPF) regime and a passive monetary and active fiscal policy (PMAF) regime is estimated to fit various U.S. samples from 1955 to 2007. The results show that data in the pre-Volcker periods strongly prefer an AMPF regime, even with a prior centered in the PMAF region. The estimation, however, is not very informative about whether the Federal Reserve's reaction to inflation is greater than one in the pre-Volcker period, because much lower values can still preserve determinacy under passive fiscal policy. In addition, whether a PMAF regime can generate consumption growth following a government spending increase depends on the degree of price stickiness. An income tax cut can yield an unusual negative labor response if monetary policy aggressively stabilizes output growth.     

Productivity Shocks and Monetary Policy in a Two-Country Model

In this paper, we examine the effects of foreign productivity shocks on monetary policy in a symmetric open economy. Our two-country model incorporates the New Keynesian features of price stickiness and monopolistic competition based on the cost channel of Ravenna and Walsh (2006). In particular, in response to asymmetric productivity shocks, firms in one country achieve a more efficient level of production than those in another economy. Because the terms of trade are directly affected by changes in both economies’ output levels, international trade creates a transmission channel for inflation dynamics in which a deflationary spiral in foreign producer prices reduces domestic output. When there is a decline in economic activity, the monetary authority should react to this adverse situation by lowering the key interest rate. The impulse response function from the model shows that a productivity shock can cause a real depreciation of the exchange rate when economies are closely integrated through international trade.     

货币政策是否应关注资产价格——基于货币稳定的视角

货币稳定是一个伴随着货币交易范围扩展而不断拓展的概念,资产交易规模使资产价格波动能严重影响货币稳定和社会福利,因此,货币稳定应当包括资产价格稳定。利用中国1998-2009年月度、季度数据,以及协整检验、误差修正估计和方差分析等方法研究后得出:资产价格与传统通货膨胀指标现值及预期值存在联动性、与经济运行中的货币存量具有显著的数量解释关系,资产价格通过影响消费、投资等经济因素冲击着货币政策效果;货币政策对维护包括资产价格在内的货币稳定并非无能为力,经验表明资产价格往往对货币政策调整做出积极反应。因此,货币稳定指标应根据传统通货膨胀指标和资产价格指标综合计算,即货币政策应根据资产价格传导机制,精确分析资产价格与货币中介目标的关系,准确采取政策工具。     

The BMW Model: A New Framework for Teaching Monetary Economics

Abstract: Although the IS/LM-AS/AD model is still the central tool of macroeconomic teaching in most macroeconomic textbooks, it has been criticized by several economists. Colander (1995) demonstrated that the framework is logically inconsistent, Romer (2000) showed that it is unable to deal with a monetary policy that uses the interest rate as its operating target, and Walsh criticized that it is not well suited for an analysis of inflation targeting. The authors present a framework that develops the Romer approach into a very simple but, at the same time, comprehensive macroeconomic model. In spite of its simplicity, it can carry the main insights of the New Keynesian macroeconomics to an intermediate level and deal with issues like inflation targeting, monetary policy rules, and central bank credibility.     

International monetary policy coordination in a new Keynesian model with NICE features

The authors provide a static two-country new Keynesian model to teach two related questions in international macroeconomics: the international transmission of unilateral monetary policy decisions and the gains coming from the coordination monetary rules. They concentrate on “normal times” and use a thoroughly graphical approach to analyze the questions at hand. In this setting monetary policy is conducted using interest rates rules and economic integration between nations does not necessarily create the case for the coordination of monetary policy. In particular, they show that the conduct of optimal national monetary policies does not make any difference with the coordination of national policies, as this creates a situation where the international monetary system operates “Near an International Cooperative Equilibrium” (NICE).     

Sovereign Debt Management and the Transformation from Keynesian to Neoliberal Monetary Governance in Britain

ABSTRACT

Private financial markets are central to the implementation of monetary governance. This necessary integration of public and private finance means the way states govern must evolve with developments in financial markets. This article examines how the rise of liability management underpinned a shift to market-based banking and transformed the operation of monetary policy in Britain. It assesses the period of reform between 1967 and 1981 and what this meant for monetary governance. Political economy literature depicts this period as a shift to depoliticised, deregulated governance with public authority giving way to market power. This paper challenges this perspective on the grounds that it misconstrues the problem policymakers faced. The shift from Keynesian to neoliberal monetary governance came in response to the change in banking practice with the rise of liability management and a parallel money market. This underpinned an explosion of credit creation that the old system of monetary policy, organised around the Base Rate and ‘primary’ discount market could not fix. As a result, the monetary authorities had to render this new financial environment governable. The period should therefore be reassessed in terms of the capacities the state attempted to construct to conduct monetary governance.     

The Discursive Dilemma in Monetary Policy

The discursive dilemma implies that the decision of a board depends on whether the board votes directly on the decision (conclusion‐based procedure) or votes on the premises for the decision (premise‐based procedure). We derive results showing when the discursive dilemma might occur. Under majority voting, a discursive dilemma can occur either (i) if the relationship between the premise and the decision is non‐monotonic, or (ii) if the board members have different judgments on at least two of the premises. Normatively, a premise‐based procedure tends to give better decisions when there is disagreement on parameters of the model.     

Explaining the Delayed Effect of Monetary Policy: The Role of Inventories and Factor-hoarding

This paper proposes a new model accounting for the delayed effect of monetary policy shocks on output. The key feature of the model is to distinguish a variety of margins (i.e., inventory adjustments, hours per worker, efforts and employments) on which firms adjust output in response to macroeconomic shock. When these multiple margins are properly introduced to an otherwise standard modern monetary business cycles model, the interplay between inventory adjustments and the one-period lag in adjusting employment can produce the hump-shaped response of output to monetary shock. Given the weak evidence on habit formation at household level found in Dynan (2000) Dynan, K. (2000). Habit formation in consumer preferences: evidence from panel data. American Economic Review, 90 (3), 391–406. doi: 10.1257/aer.90.3.391[Crossref], [Web of Science ®] , [Google Scholar] and Flavin and Nakagawa (2008) Flavin, M., &; Nakagawa, S. (2008). A model of housing in the presence of adjustment costs: a structural interpretation of habit persistence. American Economic Review, 98, 474–495. doi: 10.1257/aer.98.1.474[Crossref], [Web of Science ®] , [Google Scholar], therefore, this paper provides an alternative explanation for the delayed effect of monetary policy without relying on the habit formation.     

The Monetary Policy of the European Central Bank

The first six years of ECB monetary policy are examined using a general framework that allows central bankers to weight differently positive and negative deviations of inflation, output and the interest rate from their reference values. The empirical analysis on synthetic euro‐area data suggests that the objective of price stability is symmetric, whereas the objectives of real activity and interest‐rate stabilizations are not. Output contractions imply larger policy responses than output expansions of the same size, while movements in the interest rate are larger when the level of the interest rate is relatively high. The hypothesis of M3 growth‐rate targeting is rejected.

Non-stationary Interest Rate Differentials and the Role of Monetary Policy

Abstract

The present work deals with a frequently detected failure of the uncovered interest rate parity (UIP) – the absence of bivariate cointegration between domestic and foreign interest rates. We explain the non-stationarity of the interest differential via central bank reactions to exchange rate variations. Thereby, the exchange rate in levels introduces an additional stochastic trend into the system. Trivariate cointegration between the interest rates and the exchange rate accounts for the missing stationarity property of the interest differential. We apply the concept to the case of Turkey and Europe, where we can validate the theoretical considerations by multivariate time series techniques.

货币政策工具对资产价格动态冲击的识别检验

文章以不同的货币政策手段在资产价格波动的不同阶段所表现出的作用效果为出发点,通过SVAR模型,识别出不同货币政策工具的单独动态冲击,并分别分析了膨胀阶段和低迷阶段的资产价格对货币政策冲击响应的程度,以解决针对不同阶段资产价格波动的货币政策调控手段和时机的选择问题。结果表明,货币政策对资产价格的作用具有有效性,在价格膨胀阶段可在一定时期内采取利率手段对资产价格波动进行微调,当出现价格泡沫时控制货币供应量会收到即时效果;而在资产价格低迷阶段,以利率调节资产价格具有明显和相对持久的作用。     

基于MS-VECM模型的我国货币政策非对称研究与启示

通过建立马尔可夫区制转移误差修正模型（MS-VECM）模拟我国货币政策对经济的非对称影响,以此分析我国货币政策的有效性。根据经济波动幅度,将我国经济划分为高波动和低波动两个区制状态,经济增长波动剧烈的区制下向均衡状态调整速度快于经济波动幅度较低区制下的调整,论证了我国货币政策对经济的影响在不同区制下存在非对称性。并用模型对我国经济状况进行了模拟预测,利用这种非线性的模型能够很好地预测货币与产出增长关系,表明现阶段我国经济运行状态是一低波动区制下的正常回落,目前不宜出台强扩张性的货币政策刺激经济增长。     

The Doctoral Origins of Economics Faculty and the Education of New Economics Doctorates

For the open economy, the workhorse model in intermediate textbooks still is the Mundell-Fleming model, which basically extends the investment and savings, liquidity preference and money supply (IS-LM) model to open economy problems. The authors present a simple New Keynesian model of the open economy that introduces open economy considerations into the closed economy consensus version and that still allows for a simple and comprehensible analytical and graphical treatment. Above all, their model provides an efficient tool kit for the discussion of the costs and benefits of fixed and flexible exchange rates, which also was at the core of the Mundell-Fleming model.
