Money,Inflation and Output in Nigeria and South Africa: Could Friedman and Schwartz Be Right?

ABSTRACT

This study examines the non-linear relationship between money, inflation and output with respect to the Friedman and Schwartz hypotheses that monetary policy affects prices in the long-run but not in the short-run, and influences output in the short-run but not in the long-run. The study examines the case of Nigeria and South Africa for the period 1970–2016 using the ARDL approach. The study proved that Friedman and Schwartz were right that money growth influences output in the short-run and not in the long-run. This suggests monetary policy is neutral in the long-run; however, the findings of this study cast some doubts on their popular view that money growth affect prices in the long-run but not in the short-run. This study shows that money growth actually affects prices both in the short and long-run. Thus, it is only the long-run dimension of the second hypothesis that is valid; the short-run view of the hypothesis is invalid for both Nigeria and South Africa. In fact, the significant estimates of money growth on inflation in both countries prove that inflation is everywhere a monetary phenomenon (both in the short and long run).     

Consumption and exchange rate uncertainty: Evidence from selected Asian countries

We set out to assess the effects of exchange rate uncertainty on real consumption in selected Asian countries. Consumption influences business cycles, which in turn shape short-run monetary policy decisions. Hence, understanding factors driving consumption is appealing to policymakers. To date, few studies have analysed the effects of uncertainty on consumption. The available ones generally focus on the long-run effects, in spite of the fact that the short-run persistence and adjustments to equilibrium are equally relevant. Our study takes these limitations seriously by distinguishing the short- and long-run effects of exchange rate uncertainty on consumption. Using a flexible dynamic panel data technique that allows long-run effects to be homogeneous and the short-run effects to be heterogeneous, we find that uncertainty impedes consumption in the long run. In the short run, however, the effects are immaterial. This evidence remains robust to the measure of uncertainty, asymmetric uncertainty, inflation and the global financial crisis of 2008. By decomposing uncertainty into its temporary and permanent components, we find that the latter have a stronger effect on consumption in the long run than the former. Although both components demand policy attention, the evidence suggests that policymakers should be more concerned with permanent uncertainty.     

Is there an optimal crawl?

This paper shows that optimal exchange rate policy can be defined in terms of either a long-run secular policy or a short-run stabilization policy. The rate of crawl which maximizes real per capita consumption is shown to often differ from the exchange rate movements produced under fixed or floating exchange rates. And the optimal program for dealing with short-run speculative capital flows will involve both discrete and gradual exchange rate changes. It is also argued that domestic monetary policy and exchange rate policy are not independent instruments.     

U.S.-Africa trade balance and the J-curve: An asymmetry analysis

ABSTRACT

For the first time in the body of literature, we consider bilateral trade balance models of the US with each of her 20 trading partners from Africa and try to assess the J-curve phenomenon. After applying the linear and nonlinear ARDL approaches, we find support for the J-curve effect in three partners from the linear models. However, support rises to eight partners when we shift to nonlinear models. Furthermore, we find short-run asymmetric effects of exchange rate changes in almost all models and significant long-run asymmetric effects in half of the partners.     

The impact of monetary and tax policy on income inequality in Japan

This paper assesses the effects of the most recent monetary policy behaviour of the Bank of Japan (in particular, zero interest rate policy and negative interest rate policy) and Japanese tax policy on income inequality in this country during the period of 2002Q1 to 2017Q3. The vector error correction model (VECM) that develops in this research shows that increase in money stock (m1) through Quantitative Easing (QE) and Quantitative and Qualitative Easing (QQE) policies of the BOJ significantly increases the income inequality. On the contrary, Japanese tax policy was effective in reducing the income inequality. Variance decomposition results show that increasing of income inequality by monetary policy is larger when comparing to decreasing effects of tax policy on income inequality. Cointegration and VECM results show that monetary policy has both short-run and long-run impacts but for tax policy paper could not find any significant short-run impact on income inequality. In addition, paper found that technological progress only in long-run can reduce the income inequality by increasing the marginal productivity of labour with positive impacts on employment and wages.     

Monetary Union Viability: A Criterion Proposal

We propose a model that represents the dynamic behaviour of a monetary union comprising two countries whose natural interest rates are initially unequal. This initial disparity and the subsequent application of a common monetary policy generate different national inflation rates and lead to losses of competitiveness, foreign deficits, and the indebtedness of one country with respect to the other. We propose as a viability criterion for the modelled monetary union a combination of non‐explosive foreign debt and the ability of the central bank to neutralize the contracting effects of taking on additional debt to avoid falling into a liquidity trap.     

On dynamics in a Keynesian model of monetary and fiscal stabilization policy mix with twin debt accumulation

In this paper, a six‐dimensional model of flexible prices with the monetary and fiscal policy mix, describing the development of the firms’ private debt, the output, the expected rate of inflation, the rate of interest, government expenditure, and government bonds are analyzed. The stress put on the “twin debt accumulation” means that in our model both private debt accumulation and the public debt (government bond) accumulation are explicitly introduced. Questions concerning the existence of limit cycles around its normal equilibrium point are investigated. The bifurcation equation is found. The formulae for the calculation of its coefficients are gained. Numerical example illustrating the results attained is presented by means of numerical simulations.     

Thoughts about Monetary and Fiscal Policy in a Postinflation World

There is a cultural lag in economic policy, particularly when it comes to inflation. Should inflation continue to be a concern, or is the new “normal” one in which inflation is low on the list of threats? In particular, central banks should focus on their original mission of ensuring financial stability and recognize that monetary accommodation is likely to continue to be appropriate. Budget policy, too, must play a role in promoting economic health—but expenditures should be shifted toward investment that increases productivity rather than consumption. Also, the federal tax codes and entitlements should be restructured so that they promote rather than impede growth. Finally, it is important to guard against institutions and individuals that have enormous financial power using that power to gain short-run advantage for themselves at the expense of long-term stability and prosperity for all.     

Monetary policy and exchange rate overshooting: Dornbusch was right after all

Dornbusch's exchange rate overshooting hypothesis is a central building block in international macroeconomics. Yet, empirical studies of monetary policy have typically found exchange rate effects that are inconsistent with overshooting. This puzzling result has been viewed by some researchers as a “stylized fact” to be reckoned with in policy modelling. However, many of these studies, in particular those using vector autoregressive (VARs) approaches, have disregarded the strong contemporaneous interaction between monetary policy and exchange rate movements by placing zero restrictions on them. In contrast, we achieve identification by imposing a long-run neutrality restriction on the real exchange rate, thereby allowing for contemporaneous interaction between the interest rate and the exchange rate. In a study of four open economies, we find that the puzzles disappear. In particular, a contractionary monetary policy shock has a strong effect on the exchange rate, which appreciates on impact. The maximum effect occurs within 1-2 quarters, and the exchange rate thereafter gradually depreciates to baseline, consistent with the Dornbusch overshooting hypothesis and with few exceptions consistent with uncovered interest parity (UIP).     

Inflation,R&D and growth in an open economy

This study explores the long-run effects of inflation in a two-country Schumpeterian growth model with cash-in-advance constraints on consumption and R&D investment. We find that increasing domestic inflation reduces domestic R&D investment and the growth rate of domestic technology. Given that economic growth in a country depends on both domestic and foreign technologies, increasing foreign inflation also affects the domestic economy. When each government conducts its monetary policy unilaterally to maximize the welfare of domestic households, the Nash-equilibrium inflation rates are generally higher than the optimal inflation rates chosen by cooperative governments who maximize the welfare of both domestic and foreign households. Under the CIA constraint on R&D (consumption), a larger market power of firms amplifies (mitigates) this inflationary bias. We use cross-country panel data to estimate the effects of inflation on R&D and also calibrate the two-country model to data in the Euro Area and the US to quantify the welfare effects of decreasing the inflation rates from the Nash equilibrium to the optimal level.     

Long-run Positions and Short-run Dynamics in a Classical Growth Model

The aim of this paper is to study the qualitative impact of short-run disequilibria on long-run positions. In this perspective, we refer to a classical framework. We underline that one-sector classical growth models only deal with perfectly adjusted situations (steady-state equilibria). Such models assume that short-run dynamics are neutral in the long run which means that the steady state is defined independently of the transient dynamics. In order to show that this situation is not always realized, we propose a modified version of Kurz's growth model (“Technical change, growth and distribution: a steady-state approach to ‘unsteady’ growth”, in Kurz H. D.: Capital Distribution and Effective Demand, Blackwell, Oxford, 1990, pp. 210–239) that integrates short-run disequilibria. We obtain dynamics that exhibit a multiplicity of equilibria. Therefore, short-run events can no longer be neglected, since they contribute to the emergence of the long-run equilibrium.     

Europäischer Zinslastenausgleich — eine sinnvolle Alternative zu EZB-Anleihekäufen

The eurozone’s public debt crisis is not over yet - as displayed in the still substantial yield spreads between “northern” and “southern” euro government bonds. Whereas the ECB tried to tackle this problem by announcing (in Sept. 2012) its willingness to conduct unlimited “outright monetary transactions” to the benefit of the southern countries, the German “Institut für Weltwirtschaft (IfW)” offered a less risky option in its “Kiel policy brief” (Jan. 2013): it suggested narrowing this yield spread by establishing a “yield spread compensation fund”, which would balance out interest payments among euro countries. Though this may sound like the first concrete eurozone bailout mechanism, the idea really is a risk-free debt alleviation tool, matching windfall gains with windfall profits without too much of a bailout.     

Dove or Hawk? Characterizing monetary policy regime switches in India

The past two decades have witnessed a worldwide move by emerging markets to adopt explicit or implicit inflation targeting regimes. A notable and often discussed exception to this trend, of course, is China which follows a pegged exchange rate regime supported by capital controls. Another major exception is India. It is not clear how to characterize the monetary regime or identify the nominal monetary anchor in India. Is central bank policy in India following a predictable rule that is heavily influenced by a quasi inflation target? And how has the monetary regime been affected by the gradual process of financial liberalization in India? To address these points, we investigate monetary policy regime change in India using a Markov switching model to estimate a time-varying Taylor-type rule for the Reserve Bank of India. We find that the conduct of monetary policy over the last two decades can be characterized by two regimes, which we term ‘Hawk’ and ‘Dove.’ In the first of these two regimes, the central bank reveals a greater relative (though not absolute) weight on controlling inflation vis-à-vis narrowing the output gap. The central bank however was found to be in the “Dove” regime about half of our sample period, focusing more on the output gap and exchange rate targets to stimulate exports, rather than moderating inflation. India thus seems to be following its own direction in the conduct of monetary policy, seemingly not overly influenced by the emphasis on quasi-inflation targeting seen in many emerging markets.     

不完全汇率传递下的货币政策工具规则分析

本文尝试构建一个开放条件下的总供给-总需求模型,通过名义进口价格刚性在模型中引入汇率传递因素。模型对各种货币政策工具规则下社会福利损失函数进行比较,考察在不同的汇率传递程度下的各种货币政策工具规则。研究结果显示,社会福利水平随着汇率传递程度下降而提高;货币政策工具规则对消费者物价指数(CPI)上涨作出反应一定程度上优于对国内制造商品价格上涨作出反应,制定的货币政策工具规则应该以CPI为目标,以使社会福利损失最小。     

The Supply of Safe Assets and Fiscal Policy

Beyond fleeting references, there is surprisingly little analysis about the interrelationship between fiscal policy and safe assets. This study analyses this interrelationship and argues that, at a certain point, more public debt will not “buy” more safety: countries face a kind of “safe assets Laffer curve”, with a maximum amount of safe assets at some level of indebtedness. The position and stability of this curve depend on a number of national and international factors, including international risk appetite and the quantitative easing policies implemented by central banks. The study also finds evidence of declining safe assets, as reflected in government debt ratings.     

Determinants of domestic credit levels in emerging markets: The role of external factors

This paper empirically examines the determinants of domestic credit expansion across a wide range of 24 emerging market economies. We use a dynamic panel data estimation technique to investigate the short-run and long-run effects of internal demand and external supply factors, external balance, different measures of trade openness and global uncertainty on domestic credit. We find that loose monetary policy in the domestic market, differences between domestic and global lending rates and real trade openness positively contribute to domestic credit levels. The findings also show that external balance and perceptions of global tail risk negatively affect domestic credit levels.     

Mean reversion of inflation rates in seven Eastern European countries: An application of a fourier quantile unit root test

This paper applies recently developed Fourier quantile unit root test to investigate time-series property of inflation in seven Eastern European countries. This method combines the quantile unit root test with smooth unknown multiple breaks through Fourier function, and has good size and power when the data follows heavy tailed distribution. Our results show that the inflation rates are stationary within each quantile for Czech Republic, Bulgaria and Lithuania, while the other four countries contain a unit root within some quantiles. We also find the speed of inflation adjustment towards to its long-run equilibrium for each country is asymmetric. Our results have important policy implications for monetary authorities in these Eastern European countries.     

我国国债的财富效应探析——1985~2002年间我国国债规模对消费需求影响的实证研究

目前国内对国债效应的研究,集中于国债对投资的影响,较少论及国债对居民消费的影响。然而,国债对消费的影响同样重要。居民可能将国债作为金融财富,也可能认为国债对应着未来的税收。国债对消费的影响,取决于国债在居民的预算约束中是作为财富还是作为预期的未来税收而存在。若居民更多地将国债作为一种金融财富而不是未来税收,则国债促进消费增长并带动经济增长;反之,则形成“李嘉图等价效应”所描述的金融挤出效应。通过对1985~2002年的数据进行回归,作者发现我国国债呈现出较强的财富效应。但是,这一财富效应却是与国债存量相关的。若公众的信心发生变化,消费需求将迅速下降。这就要求国债政策的淡出只能是渐进的,以避免对居民消费造成较大的冲击。     

An Empirical Analysis of the Determinants of Interest Rates in Ghana

ABSTRACT

This paper provides an empirical analysis of the determinants of the bank lending rate in Ghana using annual time series data from 1970 to 2013. We found evidence of a long-run equilibrium relationship between the average lending rate charged by commercial banks and its determining factors. In the long run, bank lending rates in Ghana are positively influenced by nominal exchange rates and Bank of Ghana’s monetary policy rate but negatively with fiscal deficit, real GDP and inflation. We also find positive dependence of the bank lending rate on exchange rates, and the monetary policy rate both in the short and long run. Specifically, our findings reveal that the Bank of Ghana’s monetary policy rate and the exchange rate, by far, show strong contemporaneous effects on the average bank lending rate in Ghana.     

Inflation Targeting Framework and Interest Rates Transmission in Ghana: An Empirical Investigation

This paper investigates the long-and short-run rate of transmission of the prime rate to interest rates since the implementation of inflation targeting policy in Ghana. Monthly data covering the period January 2002 to March 2016 is used. The Johansen and Hansen parameter instability cointegration, the FMOLS and DOLS estimation procedures were used. The long-run results show incomplete pass-through of the prime rate to commercial banks’ lending and deposit rates but over pass-through to the 91-day Treasury bill rate. The short-run adjustment shows relatively slow transmission of the prime rate to the respective interest rates. Given the findings, relevant policy suggestions are provided.
