Monetary policy rules for a developing country: Evidence from Pakistan

This paper estimates forward-looking monetary policy rules to examine the interest rate setting behavior of the State Bank of Pakistan. Considering the external constraints on monetary policy, core inflation and a country-specific measure of the output gap, we demonstrate that the State Bank of Pakistan reacts to changes in inflation, the output gap and the federal funds rate.     

Estimating Open Economy New Keynesian Phillips Curve for Korea

We estimate the open economy new Keynesian Philips curve (NKPC) to characterize the inflation dynamics of Korea. While recent studies show that the NKPC holds for the pre‐currency crisis period, the empirical evidence is inconclusive for the post‐crisis period. Has globalization increased the role of global factors relative to domestic factors? Can labor income share still serve as a good measure of real marginal cost following the structural break? To address these issues for the post‐crisis period, we use two types of open NKPC: the relative prices model and the incomplete pass‐through model. The estimation of both models indicates that the forward‐looking behavior is important, and its role is reinforced in an open economy specification. Both NKPC models also show that the external factors are more relevant inflation drivers than the domestic factors.     

Economic Globalization and Inflation in China: A Multivariate Approach

This paper evaluates whether globalization has increased the role of global factors in driving inflation in China. Unlike other published studies on the relationship between globalization and inflation, which mostly use Phillips curve models, this paper uses multivariate dynamic models to examine the dynamic interactions between globalization and inflation in China. Empirical results with quarterly data spanning from 1995 to 2012 show that the global output gap significantly affects the dynamics of inflation in China. In particular, the global output gap is superior to the domestic output gap in predicting domestic inflation. Impulse response and variance decomposition analyses reinforce this finding. Our results indicate that the central bank of China should take developments in global output into account in its monetary policy‐making process.     

通胀、通胀预期和货币政策——基于中国2001—2010年数据的实证研究

文章用两种方法测度了我国通胀预期：（1）未来物价预期指数衡量通胀预期;（2）ARMA模型对通胀的预测值。并计量分析了影响通胀预期的因素,结果显示：CPI上升、正产出缺口增加和广义货币供应量增加,是形成通胀预期的主要因素。利率、人民币汇率和食品价格对通胀预期的形成作用不显著和影响较小。因此,存款准备金率动态微调,是目前管理好通胀预期的最好选择。     

Inflation Targeting in ASEAN‐10

The paper addresses the empirical question of whether economies that do not systematically target inflation (non‐inflation targeters) experience higher exchange rate volatility as compared with inflation targeters in 10 countries of the Association of Southeast Asian Nation (ASEAN) from 1990 to 2010. The paper examines the role of real exchange rate, exchange rate volatility and the reaction functions of central banks using dynamic panel estimation techniques. The results indicate that the output gap offers more useful information than the inflation gap in setting interest rates for inflation targeters, implying that the real term is more important than the nominal term. In turn, this suggests that an increase in interest rate can be wielded swiftly to reduce real gross domestic product and suppress inflation. The real exchange rate appears as a weaker determinant in setting interest rates for non‐inflation targeters. Inflation targeters experienced lower exchange rate volatility compared with non‐targeters in the ASEAN, which implies that implementation costs to their domestic economies may be marginally lower. Meanwhile, the non‐targeters follow a mixed strategy as both the inflation and real exchange rate are used as instruments to set the interest rates.     

THE SOUTH AFRICAN PHILLIPS CURVE: HOW APPLICABLE IS THE GORDON MODEL?

Is there a Phillips curve relationship present in South Africa and if so, what form does it take? Traditionally the method to establish whether or not there is a relationship between the output gap and the change in inflation is merely to regress the latter on the former. This yields the well‐known augmented Phillips curve. However, Gordon has argued that this specification of the Phillips curve produces biased results. Instead, he puts forward and estimates successfully for several industrialised countries his so‐called triangular model that tests for hysteresis and inertia in the behaviour of inflation, as well as the impact on inflation of changes in the output level. This paper considers whether or not Gordon's triangle model is applicable to South Africa, i.e. are hysteresis and inertia present in South Africa? In addition, in an attempt to find a better estimation of the output gap, the paper also experiments with alternative ways to estimate the long‐run output level, including the standard HP‐filter, as well as a production function approach.     

Ghostbusting: which output gap really matters?

Reflecting domestic demand pressures, the output gap has important implications for economic analysis. This paper assesses the usefulness of four commonly-used gap measures for a small set of European countries. The main results are that the policy implications can be very different depending on the gap measure and that, consequently, care should be exercised when employing any such measure. Moreover the paper investigates in a simple inflation forecasting framework the common assertion that the output gap could improve the forecasting accuracy. For annual observations, however, these measures rarely provide useful information and there is no single best measure across countries.     

European Inflation and the New Keynesian Phillips Curve

The majority of macroeconomists who have studied inflation dynamics in Europe argue that the New Keynesian Phillips Curve (NKPC) provides a good way to describe changes in the price level from the 1970 on. However the vast majority of these articles estimate the NKPC using the labor income share as the proxy for real marginal cost. This article argues that the labor share cannot serve as a proxy for real marginal cost because of its countercyclicality and the lack of labor adjustment costs. Once we account for labor adjustment costs, we are able to derive a new marginal cost proxy that is indeed procyclical; however, we find that the NKPC fails to produce coefficients consistent with its underlying structural parameters when a procyclical marginal cost proxy is used. This casts serious doubt whether the NKPC is empirically applicable to Europe or, for that matter, any other country.     

FORECASTING SOUTH AFRICAN INFLATION

This paper looks at what variables are useful for forecasting inflation starting in 1990. I show that the output gap, a measure of real economic conditions, does seem to provide useful information for forecasting inflation. This is good news for the Reserve Bank, since the primary way that the Reserve Bank tries to affect future inflation is through real economic conditions. In addition, short‐term interest rates and import price inflation also seem to provide useful information. The most accurate of these forecasts suggests a root mean square forecast error of 1–2 per cent for 1‐year ahead inflation, which is within the Reserve Bank's current target range.     

Re‐Examining the Role of Structural Change and Nonlinearities in a Phillips Curve Model for South Africa

Although studies generally find evidence of a Phillips curve‐type relationship in South Africa, uncertainty remains about the relevance of the model over a relatively long sample period, and whether conventional output gap measures are suitable proxies for demand pressure. This paper reviews research which shows that the Phillips curve model prevails over an extended sample, provided that the benchmark specifications include major structural changes in the balance‐of‐payments and labour market, and account for shifts in the root causes of inflation. When this is done, a linear specification with an output gap in levels correctly predicts the non‐trended inflation pattern over the period 1971(Q1)–1984(Q4), whereas a piecewise concave curve with an output gap in growth rates accurately forecasts the decelerating inflation pattern during 1986(Q1)–2001(Q2). A novel feature of the concave model is that it remains statistically robust and structurally stable when it is estimated until 2015(Q4). The concave model imparts a disinflationary bias, which suggests that monetary policy should be more expansionary during downswing phases of the business cycle and neutral during upswing phases. The analysis also considers how the shape of the Phillips curve might change if the balance‐of‐payments constraint on demand is relaxed in a significant way.     

MEASURING THE WELFARE COST OF INFLATION IN SOUTH AFRICA

In this paper, we estimate the long‐run equilibrium relationship between money balance as a ratio of income and the Treasury bill rate for the period of 1965:02 to 2007:01, and in turn use the relationship to obtain welfare cost estimates of inflation. Using the Johansen technique, we estimate a log‐log specification and a semi‐log model of the above relationship. Based on the fits of the specifications, we decided to rely more on the welfare cost measure obtained under the log‐log money demand model. Our estimates suggest that the welfare cost of inflation for South Africa ranges between 0.34% and 0.67% of GDP, for a band of 3‐6% of inflation. Thus, it seems that the South African Reserve Bank's current inflation target band of 3‐6% is not too poorly designed in terms of welfare.     

Macroeconomic and Sectoral Effects of International Trade: A Vector Error-Correction Study

This study examines various claims that in the U.S., international trade has contributed to a loss of manufacturing base, an increased gap between unskilled and skilled wages, lower employment, and a loss of productivity. Cointegration tests indicate that in the long run and at the macro level, the ratio of trade to output and FDI to output are correlated with the manufacturing share of output, the ratio of unskilled to skilled wages, labor productivity, and the employment rate. However, Granger causality tests reveal that, with one exception, causation does not run from trade to the domestic variables, the only exception being that FDI Granger causes productivity. When the focus is shifted to the manufacturing sector, the results support the proposition that openness to trade has had adverse effects on this sector.A slightly different version of this paper was presented at the Fifty-sixth International Atlantic Economic Conference, October 16–19, 2003 in Quebec City, Canada. The research reported in this paper is partially funded by a grant from the Institute for Global Economic Affairs at Marquette University.     

DO INTERNATIONAL MONETARY FUND PROGRAMS IMPACT ON THE SACRIFICE RATIO?

From time to time, the International Monetary Fund (IMF) makes resources available to member states for short‐term balance‐of‐payments support under an agreed arrangement know as a program. Most IMF programs include quantitative performance criteria for key macroeconomic variables, which borrowers must meet to obtain Fund resources. Standard open economy models predict that if policymakers are able to credibly commit to reducing inflation, rational economic agents will lower their expectations of inflation and, therefore, the trade‐off between inflation and output will fall. The present study tests whether IMF programs, by lending credibility to a country's adjustment program, influence the inflation–output trade‐off. The results from the study suggest that IMF programs do not significantly influence the inflation–output trade‐off. This finding is robust to changes in the estimation approach, the method used to obtain the output gap estimates and outliers.     

Inflation Forecast Targeting: An Alternative Approach to Estimating the Inflation‐Output Variability Tradeoff

We suggest a new way of computing the inflation‐output variability tradeoff under inflation forecast targeting. Our approach is based on dynamic, stochastic simulations of the average inflation rate over a two‐year horizon using the moving average representation of a vector autoregressive (VAR) model. Using real‐time data over two samples, we estimate the inflation‐output variability tradeoff for the United States and show that it has shifted favorably over time. We analyze the policy interventions required to achieve target inflation in each sample and compare these interventions over time.

本文在附加预期的菲利普斯曲线基础上,通过引入可变的技术进步变量,修正了新古典的总供给曲线,指出除预期的通货膨胀率、产出缺口外,技术进步也是影响总供给曲线的重要变量;同时将总需求曲线扩展到开放经济条件下,从而推导出了“通货膨胀率——产出增长率”系统下的总需求总供给模型。作为对扩展后模型的检验,本文利用该模型阐释了我国宏观经济运行中的“高增长与低通胀并存”现象。     

A Sticky Information Phillips Curve for South Africa

Mankiw and Reis propose the Sticky Information Phillips Curve (SIPC) as an alternative to the standard New Keynesian Phillips Curve to address empirical shortcomings in the latter. A SIPC for South Africa is estimated, and we find estimates of information updating probability between 0.69 and 0.81, somewhat higher than suggested by methods using micro‐evidence. Because the estimation requires data on expectations of current period inflation and output gap conditional on sequences of earlier period information sets, we provide a detailed analysis of the impact on our estimates of alternative proxies available in South Africa.     

Dilemma of the Silver Standard Economies: The Case of China

Exchange rate commitments implied in the silver standard originally anchored China's monetary policy and the inflation rate in the early republican period. It was believed that China's free silver standard acted as a natural check on the excessive issuing of notes by warlords and local governments. This consensus view, however, overlooks the fact that the silver standard was inherently unstable because it left no room for monetary policy to stabilize output and inflation. This article employs a formal structural model to show that a fiat currency unlinked to fluctuations in the price of silver that allows government to implement self‐adjusting monetary policies would further stabilize China's output and inflation.     

Estimating forward-looking rules for China's Monetary Policy: A regime-switching perspective

This paper introduces a regime-switching forward-looking Taylor rule to describe the monetary policy behavior and considers its estimation using a two-step MLE procedure due to Kim and Nelson (2006), Kim (2009) and Zheng and Wang (2010). By doing an empirical analysis on quarterly data for China over the period 1992–2010, our results show that the actual reactions of China's monetary policy can be well characterized by a two-regime forward-looking Taylor rule. Furthermore, it is also suggested that the interest rate policy in response to inflation and output gap is asymmetric, behaving a significant characteristic of regime-switching nonlinearity. Specifically, in the first regime the People's Bank of China targets inflation, but not focuses on the output gap; while in the second regime the central bank targets the output gap and the policy rule is not a stable framework.     

Assessing Nonlinear Dynamics of Central Bank Reaction Function: The Case of Mozambique

This paper sheds some light on the elements governing monetary policy‐making during the period 2000Q1–2015Q1 in Mozambique. We estimate a time‐varying Taylor‐type rule for the BM, using a Markov‐switching (MS) model and a Threshold model. The general finding is that the behaviour of the BM can be characterised by two regimes. In regime 1, only changes in inflation trigger a reaction by the monetary authority. This behaviour is prominent after the establishment of the monetary policy committee in 2007 (CPMO). In regime 2, the BM reacts aggressively both to cool off the economic activity and to curb inflationary pressures. Regime 2 occurred most frequently during 2000–2006, when the fiscal policy might have played an important role in output stabilization. After the establishment of the CPMO, regime 2 occurred in the context of a steep rise in fuel and food prices in 2007–2008 and in 2010. Both the MS model and the Threshold model show similar asymmetric effects. We find evidence that inflation is viewed more seriously by the monetary authorities when it is accompanied by a high output‐gap in the previous period, which triggers a more aggressive response from the monetary authorities.     

Inflation in South Africa: An Assessment of Alternative Inflation Models

We consider the relative empirical performance of a range of inflation models for South Africa. Model coverage is of Phillips curve, New Keynesian Phillips curve, monetarist and structural models of inflation. Our core findings are that the single most robust covariate of inflation is unit labour cost. We further decompose unit labour cost into changes in the nominal wage and real labour productivity. The principal association is a strong positive relationship between inflation and nominal wages, while improvements in real labour productivity report only a relatively weak negative association with inflation. Supply‐side shocks also consistently report an association with inflation. As to demand‐side shocks, the output gap does not return a robust statistical association with inflation. Instead, it is growth in the money supply and government expenditure which return robust and theoretically consistent associations with inflationary pressure.
