Oman's monetary policy transmission process under the fixed peg: some empirical puzzles

This paper highlights that an open economy, like Oman, could often enjoy partial monetary policy independence despite operating with a fixed peg, which may appear as a clear violation of the ‘macroeconomic trilemma'. While explaining the country-specific factors that create the scope for partial monetary policy independence, the paper underscores that for meaningful use of this partial monetary policy independence to attain domestic goals of inflation and output, the transmission mechanism of monetary policy must work effectively. Empirical analyses presented in this paper for Oman, however, suggest the presence of not only the ‘interest rate puzzle’ but also the ‘IS puzzle’ and the ‘Phillips curve puzzle’, which together signal the presence of significant transmission weaknesses. The paper, thus, concludes that costs stemming from loss of any monetary policy independence because of the fixed peg may not be very significant for Oman, and hence, any alternative exchange rate regime cannot be viewed as appropriate just on the grounds that an alternative regime could deliver greater monetary policy independence.     

The role of expectations in stabilization policy

This paper develops and tests a theory of the process by which private agents in an economy form expectations about government policy. Agents form and update their beliefs about the true state of government policy in a Bayesian fashion. The ‘credibility’ of a policy is defined to be the subjective probability that the government is pursuing a 'reform' policy rule. The ‘credibility’ of a reform of monetary or exchange rate policies is a function of the parameters of both monetary and fiscal policies. The theory is applied to the Chilean and Argentine exchange reforms of the late 1970's.     

Monetary instruments and policy rules in a rational expectations environment

This paper explores the implications of rational expectations and the aggregate supply theory advanced by Lucas (1973) and Barro (1976) for analysis of optimal monetary policy under uncertainty along the lines of Poole (1970), returning to a topic initially treated by Sargent and Wallace (1975). Not surprisingly, these two ‘classical’ concepts alter both the menu of feasible policy choice and the desirability of certain policy actions. In our setup, unlike that of Sargent and Wallace (1975), the systematic component of monetary policy is a relevant determinant of the magnitude of ‘business fluctuations’ that arise from shocks to the system. Central bank behavior — both the selection of monetary instruments and the framing of overall policy response to economic conditions — can work to diminish or increase the magnitude of business fluctuations. However, the ‘activist’ policies stressed by the present discussion bear little (if any) relationship to the policy options rationalized by the conventional analysis of monetary policy under uncertainty. In particular, in contrast to Poole's analysis, money supply responses to the nominal interest rate are not important determinants of real economic activity. Rather, the central bank should focus on policies that make movements in the general price level readily identifiable by economic agents.     

Macroeconomic factors and yield curve for the emerging Indian economy

This article investigates the dynamic linkages between the estimated parameters of a zero coupon yield curve and macroeconomic variables like inflation, gross domestic product growth in the presence of a monetary policy indicator in India for the period July 1997 to February 2004. The study finds that there exists strong causality from financial factors, defined by three parameters of the yield curves (‘Level’, ‘Slope’, ‘Curvature’) to macroeconomic factors; growth, inflation and monetary policy indicators (changes in the call money rate). However, the causality in the opposite direction is found to be weaker. It is found that theyield and macro factors do not cause each other before the launch of a liquidity adjustment facility, so the evidence of causality from financial to macroeconomic factors can be attributed to the introduction of a liquidity adjustment facility in June 2000. The causality from yield factors to macro factors is primarily driven by the fact that the ‘changes in level’ of yield curve brings an impact on inflation through the changes in monetary policy. This finding suggests that monetary policy plays a key role in driving the causality. This also implies that the indirect instrument of monetary policy mechanism is becoming increasingly important to influence the aggregate demand in the economy.     

Effectiveness of alternative channels of monetary policy transmission: some evidence for India

In this article, we have employed ‘shutdown’ methodology, not used before in the Indian context, to study the relative importance of alternative channels of monetary policy transmission. We have, for the first time, studied the impact of monetary policy on consumer price index (CPI) inflation. In response to a shock to the operating target, the maximum decline in gross domestic product growth occurs with a lag of two to three quarters, while the impact on inflation (both CPI and wholesale price index) is felt with a lag of three to four quarters. The interest rate channel is found to be the most dominant channel of monetary policy transmission in India.     

Domestic and foreign trade credit in the Netherlands an econometric analysis

In this study the determinants of both domestic and foreign trade credit are investigated. Data were obtained from about 1600 industrial firms in The Netherlands with 100 or more employees and covering the period 1957–1971. The main findings are as follows. In the first place, (net) trade credit turns out to be a structural source of funds for the weaker firms in the simple. Secondly, these weaker firms receive more (net) trade credit when monetary policy is tightened (this could be an argument for the authorities to pursue a general monetary policy). Finally, it appears that it is especially the buyer (debtor) who may ‘lead’ or ‘lag’ international payments in the short run.     

Credit rationing and non-price loan terms: A re-examination

This paper develops the implications of heterogeneous bank loans for borrower and lender behaviour in a competitive bank loan market by considering the own funds-loan ratio as the ‘non-price’ loan term. It is shown that in equilibrium each bank will ration its loan to borrowers by providing them with the smaller loan and requiring the higher own funds-loan ration than they would desire at the equilibrium loan rate. Moreover, restrictive monetary policy that raises the opportunity cost of granting loans decreases the loan size and increases the own funds-loan ratio, but its effect on the loan rate and credit rationing remains ambiguous. Thus credit rationing may decrease as a result of restrictive monetary policy.     

Optimal fiscal and monetary policy in an economy without capital

This paper is concerned with the structure and time-consistency of optimal fiscal and monetary policy in an economy without capital. In a dynamic context, optimal taxation means distributing tax distortions over time in a welfare-maximizing way. For a barter economy, our main finding is that with debt commitments of sufficiently rich maturity structure, an optimal policy, if one exists, is time-consistent. In a monetary economy, the idea of optimal taxation must be broadened to include an ‘inflation tax’, and we find that time-consistency does not carry over. An optimal ‘inflation tax’ requires commitment by ‘rules’ in a sense that has no counterpart in the dynamic theory of ordinary excise taxes. The reason time-consistency fails in a monetary economy is that nominal assets should, from a welfare-maximizing point of view, always be taxed away via an immediate inflation in a kind of ‘capital levy’. This emerges as a new possibility when money is introduced into an economy without capital.     

Interventions in the Yen–dollar spot market: A story of price,volatility and volume

We test the effectiveness of Bank of Japan (BOJ)’s foreign exchange interventions on conditional first and second moments of exchange rate returns and traded volumes, using a bivariate EGARCH model of the Yen/USD market from 5-13-1991 to 3-16-2004. We also estimate a friction model of BOJ’s intervention reaction function based on reducing short-term market disorderliness and supplementing domestic monetary policy. Important finding of this study are that: (i) we find ineffectiveness of BOJ interventions in influencing exchange rate trends pre-1995, in general, but effectiveness post-1995; (ii) FED intervention amplified the effectiveness of the BOJ transactions; (iii) interventions amplified market volatility and volumes through a ‘learning by trading’ process; (iv) BOJ’s interventions were based on ‘leaning against the wind’ motivations on the exchange rate trend and volumes; and (v) BOJ interventions were vigorously used in support of domestic monetary policy objectives post-1995. Though some of our findings confirm recent studies, our analysis goes deeper to provide new findings with important implications for central banks and foreign exchange market participants.     

中国企业去杠杆需考虑美联储货币政策变化吗?——加息和缩表的比较分析

本文构建了一个包含货币政策微观溢出效应的两国开放经济模型,提出企业结构性去杠杆需考虑开放经济因素,并在模型中引入企业融资约束机制,利用2002年第四季度-2018年第三季度中国沪深A股1023家上市公司平衡面板数据,实证检验美联储加息和缩表两类货币政策对我国企业杠杆率的差异性影响。研究发现,美联储缩表在初期对我国企业杠杆率的影响程度较大,但不存在长期溢出效应;而加息在初期影响程度相对较小,但对我国企业杠杆率存在长期溢出影响。在溢出方向上,美联储紧缩性货币政策会显著降低我国企业杠杆率。在溢出结构上,企业融资约束越严重,美联储货币政策对我国企业杠杆率溢出效应越明显。     

Static deviations from purchasing-power parity

The paper examines the ‘real’ effects of monetary policy in a small open economy in full stock-flow equilibrium. In the presence of government debt, an increase in the money supply generally produces deviations from purchasing power parity. Money creation through foreign-exchange purchases results in an overvaluation of the domestic currency. While its short-run effects favor the export industries, its long-run effects are thus in favor of the domestic sector. The same is true for open-market purchases, but the overvaluation is probably smaller in this case.     

The information content of the exchange rate and the stability of real output under alternative exchange-rate regimes

When the exchange rate is flexible, and thus responds to market forces, it provides agents with useful information, while when it is fixed (by a feedback rule) it does not. The implications of this asymmetry for the stability of real output under the two regimes is discussed. It is shown that whenever shocks are predominantly of one variety, or when domestic monetary shocks accompanied by one real shock, a flexible exchange rate does a better job of stabilizing real output than does a fixed exchange rate. These results undermine arguments favoring fixed exchange rates because they ‘discipline’ monetary policy. In addition, it is demonstrated that managed floating rules and exchange rate feedback rules are irrelevant for the distribution of real output.     

The effects of U.S. quantitative easing on South Africa

This paper investigates the impact of the Federal Reserve’s monetary policy on the economy of South Africa, particularly during the period of quantitative easing and thereafter from 2009 to 2018. A VAR model, including South Africa’s inflation, output, a stock market index, exchange rate, and South Africa’s policy rate is examined to determine the impact of the Federal Reserve’s actions. Our results show that the Federal Reserve’s quantitative easing programs had only slight overall effects on South Africa’s economy. However, the way monetary policy is measured appears to have important effects for studies of international monetary spillovers as the results differ depending on the type of monetary policy measure used.     

Monetary transmission via the administered interest rates channel

This paper examines the dynamics of administered interest rate changes in response to changes in the benchmark money market rate in Singapore. Our results show that the administered rates’ adjustment speed differs across both financial institutions and financial products. The financial institutions’ administered (lending and deposit) rates, moreover, are more rigid when they are below their equilibrium level than when they are above. Our finding, hence, implies that the speed of monetary transmission is not uniform across all sectors of the economy and that a tightening monetary policy takes a longer time to impact the economy than an expansionary monetary policy.     

The Value of Interest Rate Stabilization Policies When Agents Are Learning

We examine the expectational stability (E-stability) of rational expectations equilibrium in the "New Keynesian" model where monetary policy is optimally derived and interest rate stabilization is added to the central bank's traditional objectives of inflation and output stabilization. We consider both the case where the central bank lacks a commitment technology and the case of full commitment. We show that for both cases, optimal policy rules yield rational expectations equilibria that are E-stable for a wide range of empirically plausible parameter values. These findings stand in contrast to Evans and Honkapohja's findings for optimal monetary policy rules in environments where interest rate stabilization is not a central bank objective.

Contents of PMM,Volume 29 (2009)

This article appraises the recent UK quantitative easing (QE) monetary experiment. From March 2009 to February 2010, the Bank of England spent £200 billion on gilts and corporate bonds. This experiment represents, as a proportion of GDP, the most ambitious monetary policy ‘mission’ in history. Using several indicators to examine the impact of QE, our analysis leads to a conclusion which, metaphorically, is akin to that ascribed to the 1970 Apollo 13 Moon mission: a ‘successful failure’.     

Does easing monetary policy increase financial instability?

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macro-prudential policy and to the role of US monetary and regulatory policy in the run up to the Subprime mortgage crisis. There are two main results. First, interest rate rigidities in a monopolistic banking system increase the probability of a financial crisis (relative to the case of flexible interest rate) in response to contractionary shocks to the economy, while they act as automatic macro-prudential stabilizers in response to expansionary shocks. Second, when the interest rate is the only available instrument, monetary policy faces a trade-off between macroeconomic and financial stability. This trade off is both qualitative and quantitative in response to contractionary shocks, while it is only quantitative in response to positive shocks. We show that a second instrument, such as a Pigouvian tax on credit to households on the demand side of the market, is needed to restore efficiency in the economy when both frictions are at work.     

当前中国宏观经济总需求及货币政策调控

从我国三大需求对经济增长的贡献看,内需是中国经济增长的主要动力源,外需为中国经济发展做出了重要贡献。货币政策对总需求的调控主要通过信贷渠道和利率渠道进行传导,但由于我国市场微观主体对利率信号不敏感,利率传导途径受到限制。货币政策利率传导途径有效的前提是微观主体根据货币政策做出决策后须有条件实现自己的选择,并因自己的行为获取利益或承担损失,这样才能建立起传递及时、反应敏感的传导机制,更好实现货币政策的调控目标。因此,要提高货币政策效应,应更多从夯实市场微观基础、健全市场竞争机制等方面来考虑。
