Optimal Choice of a Proximate Monetary Target in an Open Economy*

This paper investigates the implications of hitting a monetary target (rate of interest or money supply) in an open economy. The technique of linear optimal control is applied to a small open economy of the Australian economy. A feature of the model is the interrelationship between the monetary and open sectors which complicates the use of monetary policy. Four optimal control experiments are reported in detail. The results indicate that we should aim for a money-supply target rather than an interest-rate target and that some assistance from fiscal policy should be provided to monetary policy in order to achieve this target.     

Monetary Policy Rules for a Small Open Economy

In this paper, the optimal choice of a monetary target is investigated for a small open economy that is subject to foreign monetary policy shocks. In contrast to large parts of the literature, pegging the exchange rate is never the best policy choice for the small open economy in our model. Instead, monetary targeting and, depending on the parameter combination, producer price index targeting come closest to the optimal policy rule in terms of welfare. Generally, the welfare performance of the simple targeting rules under consideration hinge critically on the degree of pass-through in the home economy and in the rest of the world.     

On the role of money in a business cycle model of a small open economy: The case of Spain

This paper examines the consequences of introducing a cash-in-advance constraint into a small open economy business cycle model for the Spanish case. A business cycle model is built extending Correia, Neves and Rebelo's (1995) small open economy framework and Cooley and Hansen's (1995) monetary economy. Money is introduced through a cash-in-advance constraint. The stochastic simulation of the model and its comparison to Spanish data show that the model is able to mimic i) the Dolado et al. puzzle, that is, the high volatility of private consumption for this economy; ii) the Dunlop-Tarshis observation, i.e., the negative correlation between real wages and hours worked; and iii) some cyclical features of the nominal dimension.     

Sectoral labor adjustment and monetary policy in a small open economy

This paper studies the welfare implications of sectoral labor adjustment cost in a two-sector small open economy model with sticky prices. We find that, when the economy faces external shocks, if monetary policy can stabilize the real economy, then sectoral labor market adjustment cost will lead to welfare loss. However, if monetary policy such as fixed exchange rates cannot stabilize real variables, then some degree of labor market friction will improve welfare instead and the gain will be significant. As a result, the welfare gap between flexible exchange rates and fixed exchange rates decreases with sectoral labor market friction. This is because the friction can offset some of the nominal rigidity and become a substitute for monetary policy to stabilize the real economy.     

The effects of monetary policy: a DSGE model analysis of Taiwan

This article attempts to use empirical data to analyse the impact of monetary policy in a dynamic stochastic general equilibrium model. According to the monetary policy decisions of the Central Bank of China (Taiwan), maintaining price, financial stability and fostering economic growth are the ultimate goals of monetary policy during the empirical period. First, this article uses the cointegration tests to determine the operating targets, the intermediate targets and the ultimate goals of monetary policy. Then, a forward-looking aggregate demand–aggregate supply model for a small open economy is specified, and policy discretion is included in this model. Finally, the model is estimated by a linear state space model and is used to analyse the short-run effects of a systematic monetary change.     

Optimal monetary policy for a small open economy

This paper focuses on the design of monetary policy rules for a small open economy. The model features optimizing behavior, general equilibrium and price stickiness. The real exchange rate is shown to affect the firm's real marginal cost, aggregate supply and aggregate demand. The welfare objective depends on the openness of the economy, and the optimal policy rule differs from that which obtains in a closed economy. The inflation versus output gap stabilization trade-off is caused by the real exchange rate. The implied optimal monetary policy regime is domestic inflation target coupled with controlled floating of the real exchange rate.     

Real Effects of Monetary Policy in New Zealand

This article analyses the dynamic effects of unexpected domestic and foreign monetary policy shocks on industrial output in New Zealand based on a new open economy macroeconomic model. Empirical analyses are performed using unrestricted recursive open economy vector autoregressive models involving policy and non‐policy variables for New Zealand and four of its most important trading partners (that is, Australia, Japan, the United Kingdom and the United States). The empirical findings are in accord with the qualitative predictions of the conventional monetary transmission mechanism applicable to a small open economy. Consequently, no empirical anomalies are observed in the dynamic behaviour of New Zealand industrial output in response to restrictive monetary innovations of domestic and foreign origin.     

ESTIMATED DYNAMIC STOCHASTIC GENERAL EQUILIBRIUM MODEL OF THE TAIWANESE ECONOMY

Abstract.  I develop a small open economy dynamic stochastic general equilibrium model to study monetary policy and the business cycle in Taiwan. Several versions of the model with different representations of Taiwanese monetary policy are estimated using Bayesian techniques. The major findings are that: (i) monetary policy in Taiwan is best described by a money supply growth rate rule; (ii) the Taiwanese economy is more flexible than the Euro area economy; and (iii) export price mark-up and investment-specific technology shocks are the main driving forces of output growth fluctuations in Taiwan.     

Real wage rigidities and optimal monetary policy in a small open economy

The main objective of the study is to provide a theoretical analysis of optimal monetary policy in a small open economy where households set real wage in a staggered fashion. The introduction of real wage rigidities plays a important role to resolve main shortcomings of the standard new Keynesian small open economy model. The main findings regarding the issue of monetary policy design can be summarized as three fold. First, the optimal policy is to seek to minimize variance of domestic price inflation, real wage inflation, and the output gap if both domestic price and real wage are sticky. Second, controlling CPI inflation directly or indirectly induces relatively large volatility in output gap and other inflations. Therefore, both CPI inflation-based Taylor rule and nominal wage-inflation based Taylor rule are suboptimal. Last, a policy that responds to a real wage inflation is most desirable.     

The real balance effect and the non-neutrality of money in a simple model of a small open economy

The paper examines the implications of the real balance effect for the neutrality of money in a small open economy model which contains an explicit treatment of aggregate supply. Two specific results emerge. First, an unanticipated monetary expansion is neutral in both the long and short runs, whilst an anticipated increase in the money supply has real short-run effects. Secondly, the non-neutrality associated with an anticipated monetary expansion manifests itself in a fall in output and employment during the transition to the new steady-state.     

A structural VAR business cycle model for a volatile small open economy

New Zealand is a small economy exposed to a volatile climate, relatively volatile international trade prices, and its exposure to international financial markets has increased markedly since economic reforms in the 1980s. This paper applies identification techniques suggested by Cushman and Zha [Cushman, D.O. and Zha T.A., 1997. Identifying monetary policy in a small open economy under flexible exchange rates, Journal of Monetary Economics, 39, pp. 433–448.], Zha [Zha, T.A., (1999). Block recursion and structural vector autoregression, Journal of Econometrics, 90, pp. 291–316.] and Dungey and Pagan [Dungey, M. and Pagan, A., 2000. A structural VAR model of the Australian economy, The Economic Record, 76, pp. 321–342.] to develop a large four block structural VAR model of the New Zealand business cycle to capture these features. The model reveals that climate and international trade price shocks have been more important sources of business cycles fluctuations than international or domestic financial shocks. Furthermore, the model does not encounter the price and exchange rate puzzles that have bedevilled attempts to identify monetary policy shocks in small open economy SVAR models.     

The Choice of an Optimal Exchange Rate System for a Small Country Under the three Good and three Country Model

The purpose of this paper is to analyze the problem of the choice of an optimal exchange rate system for a small country in terms of insulation from foreign real and monetary disturbances and in terms of minimizing the output variance around desired output. We employ a simple open macroeconomic model which can represent a small country's economy where the production of domestic output is dependent upon the intermediate goods from the rest of the world and where there are a variety of controls over foreign exchange and capital flows by a monetary authority.

Wage rigidities and unemployment fluctuations in a small open economy

This study analyzes the implications of the monetary policy for the unemployment rate in a small open economy. We introduce nominal wage rigidities and unemployment into the small open economy version of the dynamic stochastic general equilibrium model. We derive three main findings. First, under nominal wage rigidities, the cyclical properties of the calibrated model, in response to a productivity shock, are consistent with the empirical evidence on a decrease in employment and an increase in real wages. Second, for all the variables considered, the Taylor rule tracks the optimal policy better than the simple rule with unemployment as an argument. Third, regardless of the output or unemployment gap being targeted, it is not optimal that central banks respond to nominal exchange rate variations.     

International macroeconomic interdependence and imports of oil in a small open economy

To the extent that oil imports may be relevant to the international dimension of policy, we study the transmission of shocks to open economies dependent on oil within a NOEM framework through a DSGE model of a small open economy with flexible prices, staggered price setting and local currency pricing. For this purpose we introduce imports of oil as a new intermediate good needed to produce the final good and, apart from the usual exogenous shocks when a small open economy is being modeled, we consider an uncovered interest-rate parity shock, a technology shock and an oil price shock. A second-order accurate solution method is used to solve numerically a calibrated model for Portugal and Spain and the simulation results are compared with historical data, showing similar volatilities and expected dynamic responses to exogenous shocks. The model is computed with an optimized Taylor-style interest rate rule that includes real exchange targeting, thus arguing in favour of an international dimension of monetary policy.     

The relationship between exchange rates and interest rates in a small open emerging economy: The case of Romania

This paper revisits the relationship between interest rates and exchange rates in a small open emerging economy using wavelet-based methodologies. Based on data for Romania, our results confirm the theoretical predictions on the interest rate - exchange rate relationship during turmoil or policy changes. In the short term, the relationship is negative, confirming the sticky-price models, and over the long term, the relationship is positive, confirming the Purchasing Power Parity theory. At the beginning of the turmoil, the exchange rate movements generally take the lead over the interest rates for the first month, but the monetary authorities take the lead afterwards. Our results reveal that in a small open emerging economy with a direct inflation targeting monetary policy regime, the relationship between exchange rates and interest rate is fundamentally different from that in an advanced economy. Also, our results stress the necessity that the central bank must pay simultaneous attention to both variables in order to achieve their monetary policy targets.     

Global financial crisis as a phenomenon of stock market overshooting

Inspired by Dornbusch’s model of exchange rate overshooting we develop a theory of stock market behaviour and its impact on the real economy. The idea is that stock market prices overshoot and undershoot their long-run equilibrium values which are determined by the development in the real economy. The overshooting is triggered primarily by a loose monetary policy. With our model we explain the genesis of the global financial crisis (GFC) 2008/2009 primarily as the result of a loose monetary policy in the USA. Following the overshooting and crash in the stock market the real economy dropped into a recession. After modelling the interaction of three markets with different speed of adjustment—money, stocks and goods—for a closed economy we expand it to an open economy and lastly study the spillovers of a financial market crisis between countries (from a large to a small country) by introducing the transmission channels of external trade or cross-border financial transactions. A long-lasting monetary easing as exhibiting by the Fed and the ECB since 2007 and 2008, respectively could—according to our model—generate another boom-bust cycle.     

Evaluating inflation targeting as a monetary policy objective for India

This study formulates a small open economy model for India with exchange rate as a prominent channel of monetary policy. The model is estimated using the Instrumental Variable-Generalized Methods of Moments (IV-GMM) estimator and evaluated through simulations. This study compares different cases of domestic and CPI inflation targeting, strict and flexible inflation targeting, and simple Taylor type rules. The analysis highlights the unsuitability of simple Taylor-type monetary rules in stabilizing the Indian economy and suggests that discretionary optimization works better in stabilizing this economy. There seems to be a trade-off between output gap stabilization and exchange rate stabilization in flexible domestic inflation targeting and CPI inflation targeting respectively. However, flexible domestic inflation targeting seems a better alternative from an overall macro stabilization perspective in India where financial markets are still not sufficiently integrated to ensure quick transmission of interest rate impulses and existence of rigidities in the economy.     

Even more on monetary policy in a small open economy

It is well known that in a small open economy with full capital mobility and a fixed exchange rate, monetary policy is ineffective in influencing real output (e.g. the works of Fleming [Int. Monetary Fund Staff Pap. 9 (1962) 369.] and Mundell [Can. J. Econ. Polit. Sci. 29 (1963) 475.]). However, Wu [Int. Rev. Econ. Finance 8 (1999) 223.] finds that when the credit channel is added to this model, monetary policy can have real effects under a fixed exchange rate system. This conclusion hinges on the assumption that open market operations have no effect on foreign exchange reserves of the central bank when evaluating how a change in monetary policy affects the loan market. This assumption is incorrect because under a fixed exchange rate regime, the quantity of foreign reserves becomes endogenous in the model. It is shown that when this assumption is relaxed, monetary policy is still ineffective in influencing output under a fixed exchange regime, even with an operative credit channel.     

On the Effects of Inflation Shocks in a Small Open Economy

The effects of monetary policies remain always an important topic in macroeconomics. In the literature (closed and open economy), there is no theoretical as well as empirical consensus regarding the effects of monetary policies. In this paper we examine the real effects of inflation in an open economy. Australia is a classic example of a small open economy and is known to exercise inflation targeting. Using quarterly data from Australia and employing vector autoregressive (VAR) analysis, we provide evidence that inflation, both in the short and long run, negatively affects durable and non‐durable consumption and investment, and has a positive effect on the current account. Further, we show that consumption of durable goods is more sensitive than the consumption of non‐durables during the initial periods following inflationary shocks.
