Influence of the Banks' Money Mediation Behavior on the Monetary Policy: A Study of Korean Case

Abstract

This paper analyses how financial institutions' arbitrary intermediation behaviors, including adjustments in bank lending and deposit rates, influence monetary policy transmission channels. For the analysis, we develop a New Keynesian Dynamic Stochastic General Equilibrium (NK DSGE) model with parameters estimated to fit the Korean conditions. The role of banks is subsequently examined by classifying monetary policy transmission channels (real rate channel, nominal debt channel, financial accelerating channel, and banking attenuator channel). A notable part of this analysis is the inclusion of the banking sector in the model specifically with the intent to study transmissions from the financial sector to the real economy. This paper follows this line of inquiry with recent research in mind. Empirical analysis verifies the existence of the banking attenuator effect in Korea, which means banks act to reduce the effect of monetary policies. This indicates that if financial intermediaries strengthen arbitrary adjustment behaviors of lending and deposit rates, the effect of the monetary policy intended to relieve volatility in the business cycle may not be as high as expected.     

On the determinants of exporters' currency pricing: History vs. expectations

The purpose of this paper is to investigate why the choice of invoice currency under exchange rate uncertainty depends not only on expectations but also on history. The analysis is motivated by the fact that the US dollar has historically been the dominant vehicle currency in developing countries. The theoretical analysis is based on an open economy model of monopolistic competition. When the market is competitive enough, the exporting firms tend to set their prices not to deviate from those of the competitors. As a result, a coordination failure can lead the third currency to be a less efficient equilibrium invoice currency. The role of expectations is important in selecting the equilibrium in the static framework. However, in the dynamic model with staggered price-setting, the role of history becomes another key determinant of the equilibrium currency pricing. The role of history may dominate the role of expectations when the firms are myopic, particularly in the competitive local market. It also becomes dominant in the staggered price setting when a fraction of the new price setters are backward-looking. The result suggests the importance of history in explaining why the firm tends to choose the US dollar as vehicle currency. J. Japanese Int. Economies 20 (4) (2006) 548–568.     

Macroeconomics of Agricultural Trade Liberalization

Abstract

In this article a macroeconomic model is built to examine interactions between the agricultural sector and the industrial sector in an emerging market economy. This article examines how monetary shock and real shocks produce agricultural price fluctuations and change in employment through multiple cross effects. Monetary shocks result in overshooting of primary commodity price while real shock in terms of rise in the production of primary commodity mitigates the volatility of primary price.     

A Preconceived Formula for Sovietization: The Communist Takeover of North Korea

Abstract

This article examines an endogeneity issue within the Optimum Currency Area (OCA) theory. According to the cost-benefit analysis, we found that there are the upper and the lower bounds in the degree of monetary integration for a monetary union to be created. We also found that a country may secede from the monetary union, depending on its degree of integration. A country may also secede when production specialization is facilitated with monetary integration within a framework of the “OCA line”. We also consider the endogeneity of the “OCA Index”, and applied our analysis to the optimum number of world currencies.     

Real Exchange Rate Dynamics in the Asian Economies: Can Regime Shifts Explain Purchasing Power Parity Puzzles?

Abstract

We show that the strong version of the purchasing power parity (PPP) hypothesis holds in most of the US dollar real exchange rates using cointegration method that accounts for breaks in the models. The break dates in seven of the Asian currencies coincide with the two rounds of currency depreciation recorded during the 1997–1998 financial crises. We obtain a mean half-life estimate of about 10 months for PPP to converge to its long-run equilibrium level. Our confidence intervals based on persistence profile approach for the half-lives is much narrower than previous evidence might indicate. Taken together, these results show that mean reversion is stronger than commonly thought.     

The case for price level or inflation targeting—What happened to monetary policy effectiveness during the Japanese disinflation?

This paper examines whether price level or inflation targeting would have been appropriate policy choices for Japan during its disinflation and deflation period. We employ Markov switching and structural vector autoregressions, together with structural IS equations, to investigate monetary policy effectiveness during the Japanese disinflation. We find evidence of regime switching in the mid-1990s in a model including the nominal policy interest rate. When monetary policy shocks are identified by using the McCallum rule for monetary base, a monetary expansion is found to have a statistically significant impact on prices. Moreover, a lower real ex ante interest rate can still stimulate the economy despite the zero lower bound on nominal interest rates.     

Determinants of Malaysian Trade Balance: An ARDL Bound Testing Approach

Abstract

This paper examines the short- and long-run relationships between trade balance, real exchange rates, income and money supply in the case of Malaysia. The inclusion of income and money variables in the study is purposely to examine the monetary and absorption approaches to the balance of payments beside the conventional approach of elasticity, using exchange rates. Using the bound testing approach to cointegration and error correction models, developed within an autoregressive distributed lag (ARDL) framework, we investigate whether a long-run equilibrium relationship exists between trade balance and the determinants. Additionally, we adopt an innovation accounting by simulating variance decompositions (VDC) and impulse response functions (IRF) for further inferences. Using this approach, we find evidence of a long-run relationship between trade balance and income and money supply variables but not between trade balance and real exchange rate. The findings also suggest that Marshall–Lerner condition does not hold in the long-run for Malaysia and for policy wise the Malaysian trade balance/balance of payments should be viewed from absorption and monetary approaches.     

Policy Choices and Resilience to International Monetary Shocks

Abstract

The well-known trilemma theory states that the nominal exchange rate regime plays a crucial role in a country's ability to pursue monetary policy that is for its domestic objectives independent from other countries' influences. In particular, a flexible exchange rate is required for an independent monetary policy. Capital controls may help a country with a fixed exchange rate to gain some policy space but the effect of capital controls is leaky and often short-lived. We revisit these conventional wisdoms and find no strong evidence supporting them in practice. In particular, a flexible exchange rate does not reliably deliver monetary policy independence, but capital controls do. This is consistent with the view that most (developing) countries dislike either depreciation or appreciation of their currencies, and therefore would choose to follow US monetary policy moves even if they are on a flexible exchange rate regime. In other words, to build resilience to international monetary policy shocks, capital controls are a necessarily component.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.     

Sources of Real Exchange Rate Volatility in Africa: The Case of ECOWAS*

Abstract: This study examines the impact of (real) demand shocks, (aggregate) supply shocks, and monetary shocks on real exchange rates in 13 West African countries. We observe that the real demand shocks explain most of the fluctuations in real exchange rates in all these countries. Accordingly, policymakers should adopt a careful demand management strategy by controlling government expenditure and taxes.     

Monetary Policy in the Industrial World: Reflections on some Basic Issues

Abstract

This paper is a general assessment of monetary policy in major OECD countries during the 1990s. Within a simple policy framework that combines money growth, nominal income, and an open economy IS-LM type Mundell-Fleming model, the paper discusses the major strands in the conduct of monetary policy in developed industrial economies. It throws light on such problems as “rules versus discretion”, management of exchange rates, the effect of monetary changes on income and prices, and the rupture of monetary policy with other instruments of economic policy that also affect the economy.     

Monetary Policy and Sectoral Bank Lending in Malaysia

Abstract

Unlike most studies on the effect of monetary policy on bank lending, this article intends to answer the question whether the tightening of monetary policy in Malaysia before and after the financial crisis in 1997 affected differently the commercial bank lending to various sectors of the economy. To achieve the objective, Vector Autoregressive Regression (VAR) method was used to generate impulse response function and variance decomposition to trace the impact of a shock in monetary policy on bank lending in Malaysia. The results show that a monetary policy tightening in Malaysia gives a negative impact on all the sectors. Analyzing sectoral responses to monetary shocks, evidence is found that some sectors are more affected than the others. The manufacturing, agricultural, and mining sector seems to decline more than the aggregate bank lending in response to interest rate shock.     

China's monetary policy surprises and corporate real investment

We evaluate the effect of China's monetary policy shocks on corporate real investment. We propose a new approach to identify China's monetary policy shocks using high-frequency surprises based on treasury futures around monetary policy announcements as external instruments. We then estimate the dynamic effect of monetary policy shocks on corporate real investment using a rich firm-level data of all listed non-financial firms in China. We find that an unexpected monetary policy easing boosts firms' investment expenditures with heterogeneous dynamic responses across firms: small-sized firms have quicker responses than large-sized firms, especially for non-state-owned enterprises (non-SOEs). We show that sales revenue response could be the channel through which monetary policy shock transmits to non-SOEs' investment expenditures in China.     

On the choice of an anchor for the GCC currency: does the symmetry of shocks extend to both the oil and the non-oil sectors?

This paper assesses the costs of forming a monetary union among the Gulf Cooperation Council (GCC) countries by looking at economic linkages within the GCC, and between the GCC and the potential anchors (the US, and major European countries such as France, Germany and Italy) for their proposed new currency. We investigate the importance of the US dollar compared to the Euro by focusing on aggregate demand (AD) and aggregate supply (AS) shock symmetry across these countries. We differentiated between oil and non-oil sector by estimating structural vector autoregression (SVAR) models with a combination of variables: oil output, non-oil output, total output, nominal/real price of oil and overall price level. One set of models was identified with the long-run restrictions of Blanchard and Quah (Am Econ Rev 79(4):655–673, 1989), whereas the set that assesses the robustness of the findings was estimated with the short-run restrictions of Sims (Eur Econ Rev 36(5):975–1000, 1992). We find overwhelming support for AD shock symmetry across the GCC countries and between the GCC and the US, but none for the major European countries with the GCC. Non-oil AS shocks are mostly asymmetric, but oil AS shocks are mostly symmetric when the real price of oil is included. This agrees with the view that GCC countries are subjected to common oil shocks. It also suggests that previous VAR models estimated to pass judgment on the feasibility of monetary union across GCC countries may have suffered from problems of mis-specification if the real price of oil was not considered. We surmise that the US dollar is a better anchor candidate for anchoring the new GCC currency than the Euro, since US monetary policy can at least help smooth demand shocks in these countries.     

The Asymmetric Loss Function and the Central Banks’ Ability in Developing Countries

Abstract

This paper seeks to develop a theoretical strand of research in monetary economics by modelling central bank ability in the loss function. Recently, many working papers issued by the International Monetary Fund (IMF) prove that some central banks, particularly from developing countries, are suffering from serious operational problems that might affect their abilities to control the economy. Simultaneously, a literature review shows that the movements are toward using asymmetric loss function. Therefore, we utilize this function in the standard monetary approach. The results proved that both central bank ability and preference in developing countries are fundamental to explain inflation bias and the movement of monetary policy instrument.     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42     

ASSESSING MONETARY POLICY IN SOUTH AFRICA IN A DATA‐RICH ENVIRONMENT

This paper examines the efficacy of monetary policy in the South African economy using a data‐rich framework. We use the Factor‐Augmented Vector Autoregressive (FAVAR) methodology, which contains 110 monthly variables for the period 1985:02‐2007:11. The results, based on impulse‐response functions, provide no evidence of the price puzzle observed in traditional Structural Vector Autoregressive analysis and confirm that monetary policy in South Africa is effective in stabilising prices. Unlike the traditional vector autoregressive approach, the FAVAR methodology allows further analysis of a large number of variables. Variables from real and financial variables react negatively to a contractionary monetary policy shock. Finally, we find evidence of the importance of a confidence channel transmission following a monetary policy shock.     

Exchange Rate Pass-through,Unemployment and Optimal Implementable Monetary Policy Rule for Emerging Economies

Abstract

This paper develops a small open economy model with nominal rigidities and search-matching frictions to study the implications of exchange rate pass-through for monetary policy in emerging countries. I find that, with complete exchange rate pass-through, the optimal policy rule features unemployment targeting as well as inflation targeting. However, the welfare gain from responding to unemployment fluctuations diminishes as the rate of exchange rate pass-through to import prices decreases. With low exchange rate pass-through, the optimal monetary policy is strict inflation targeting.     

Monetary theory and monetary policy a central banker's view

Summary In this article attention is paid to monetary theory, the relationship between the instruments of monetary policy and other important macro-economic policy instruments, and finally to the real possibilities of pursuing an effective monetary policy. The conclusion from the theoretical analysis is that the total money supply must be considered one of the most important macro-economic policy instruments. An excessive supply of money will sooner or later lead to inflation, to the debasement of money. Therefore the volume of money should be controlled. The use and effectiveness of monetary policy should always be seen in the context of other policy instruments, especially fiscal policy and, under circumstances, wage- and price policy. The possibilities to pursue an effective monetary policy are not unlimited. The effectiveness of such a policy can,e.g., be hampered by external factors. It is vital for a central bank to have the widest possible range of instruments at its disposal.     

Is an Optimum Currency Area Feasible in East and South East Asia?

Abstract

In the backdrop of the recent economic crisis in the European Union, this study attempts to assess the degree of regional integration and the suitability of a monetary union in the East and South-East Asian (ESEA) region. For this purpose, we analyse the issue in a variety of ways. First, a long-run linkage of real output of the countries is tested using the cointegration analysis. Results suggest that real output of most of the countries in the region is cointegrated and move together in the long-run. To analyse the issue in detail, we focus on the impact of three different shocks, namely global, regional and country-specific, on real output of the countries. Results of impulse response and variance decomposition analysis reveal that regional shocks do not dominate in the sample countries, which is an indication of unfavourable condition to form an optimal currency area (OCA) in the region. These results are further confirmed by the outcome of computation of the modified Bayoumi and Eichengreen's Indices. Finally, we employ the concept of Generalized Purchasing Power Parity (G-PPP), which however reveals that the bilateral real exchange rate of ESEA countries move together in the long-run and share a common stochastic trend, which in turn provides some empirical support for an OCA in the region.
