Monetary Expansion in an Open Economy of Intermediate Size*

This paper introduces a monetary asset, perceived as an addition to wealth, into a two-country neoclassical model of accumulation. As domestic monetary expansion changes, demand for the investment good is shifted. This alters the terms and level of trade as well as production and shifts the balanced growth paths of both economies. For a non-specialized world it is found that an increase in domestic monetary expansion will increase the domestic overall capital intensity, decrease the foreign overall capital intensity, and worsen the terms of trade for the country importing the investment good.     

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.     

Economic Growth,Terms of Trade and Welfare in an Open Monetary Economy*

The authors investigate the impact of growth on terms of trade, absolute prices and welfare using a two-country, monetary model. Under flexible exchange rates export-biased growth would lead to a decline in the terms of trade if the two countries are ‘similar’. Under fixed exchange rates a weaker condition than the barter condition of export-biased growth is sufficient, namely, for the import commodity the demand creating effect of growth dominates the supply effect while for the exported commodity the opposite holds. Secondly, substitutability between money and commodities indicates that no necessary relation holds between the terms of trade and the trade balance. Thirdly, the introduction of money creates a real balance effect so that decline in terms of trade is no longer a necessary (or sufficient) condition for immiserization. Finally, the paper concludes by questioning two policy conclusions drawn in earlier models: one, that the declining terms of trade of less developed countries was due to a bias in the growth strategy and, two, that monetary models of trade support the ‘monetarist’ proposition that growth and a deteriorating trade balance can only co-exist if the domestic monetary policy is nonneutral.     

Environmental Pollution in an Open Economy*

This paper attempts to analyze an interaction between international trade and domestic environmental pollution. A country engaging in international trade biases its domestic economic structure toward exportable sectors. The bias thus caused has a significant impact on the quality of the environment. It will be shown that a country can and should control international trade activities as a means of dealing with pollution problems. One of the paper's main purposes is to give a warning to a country which expands its international trade activities without taking serious consideration of its domestic environment.     

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.     

Trade Unions in an Open Economy: A General Equilibrium Analysis*

This paper derives a general equilibrium demand-for-labour schedule within the Heckscher-Ohlin-Samuelson model of a large open economy, and then introduces an economy-wide labour union that maximizes its utility subject to this demand schedule, thereby determining the real wage and hence total employment A parametric shift's comparative-static effects on the equilibrium levels of unemployment and welfare are analyzed within this fully unionized economy.     

开放条件下我国货币政策的国际协调

开放条件下，一国货币政策进行国际协调是十分重要的。本文对货币政策国际协调的理论研究作了简要回顾，并结合我国1994年以来货币政策的实践进行分析。文章发现，我国货币政策进行国际协调的实践并不多，与汇率政策之间多次存在冲突，与美国货币政策有过简单协调。当前人民币升值压力实际上来自我国货币政策如何与美国等发达国家的经济政策进行协调。从过去实践来看，我国货币政策国际协调的问题主要是如何在现存汇率体制下实现货币供给的独立性。文章认为，在进行汇率调整基础上，我国货币政策进行国际协调的难度将降低。

Structural Balance of Trade Deficits in a Small Open Economy with Exogenous Capital Flows: A Monetary Approach*

This paper presents a ‘structural’ balance of trade model which can be interpreted as combining two major building blocks. The first one is identical to the monetary approach to the balance of payments. The second, which explains the price level, consists of the orthodox Scandinavian model of price and wage determination. It is shown that under these assumptions the balance of trade deficit can be broken down into a structural, an imported, and a ‘home-made’ component. A n empirical illustration of the structural balance of trade model is given for the New Zealand economy.     

Monetary Policy and Exchange Rate Volatility in a Small Open Economy

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap. We use the resulting framework to analyse the macroeconomic implications of three alternative rule-based policy regimes for the small open economy: domestic inflation and CPI-based Taylor rules, and an exchange rate peg. We show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail. We also discuss a special case for which domestic inflation targeting constitutes the optimal policy, and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules.     

Monetary Policy Games and International Migration in a Small Open Economy

The paper shows that international migration may improve the position of both policymakers and unions in small open economies irrespective of whether they cooperate or not. This result implies that both unions and policymakers in small open economies may welcome a further increase in international labor flow in the future. When allowance is made for real GDP per capital considerations on behalf of the policymaker, it is found that aggressive union behavior may increase the inflationary bias. Aggressive unions may insulate themselves, while soft unions lose. The presence of migration does not necessarily lead to a better outcome.     

Monetary Policy and Exchange Rate Interactions in a Small Open Economy

The transmission mechanisms of monetary policy in a small open economy like Norway are analysed through structural VARs, with special emphasis on the interdependence between monetary policy and exchange rate movements. By imposing a long‐run neutrality restriction on the real exchange rate, thereby allowing the interest rate and the exchange rate to react simultaneously to news, I find considerable interdependence between monetary policy and the exchange rate. In particular, following a contractionary monetary policy shock, the real exchange rate immediately appreciates, after which it gradually depreciates back to the baseline. The results are found to be consistent with findings from an “event study”.

Borrow and Adjust: Fiscal Policy and Sectoral Adjustment in an Open Economy*

Should the government run fiscal deficits in response to an adverse external shock that warrants transfer of resources from production of nontraded to traded goods? This article considers normative fiscal policy implications of sectoral adjustment costs in a two‐sector model with overlapping generations. Fiscal deficits benefit present generations by depleting foreign assets and slowing down the adjustment process. We show that despite no nominal rigidities, temporary fiscal deficits increase social welfare if adjustment costs prevent immediate sectoral reallocation of inputs. If there are no adjustment costs, the case for fiscal deficits vanishes.     

Monetary Policy in a Very Open Economy: Some Major Analytical Issues

This paper develops three considerations relevant to the possibility of modification of the Hong Kong currency board system for conducting monetary/exchange‐rate policy. The first concerns the system employed by Singapore, an economy similar in several ways to Hong Kong's, whereby the exchange rate is adjusted periodically in activist response to inflation and output developments. The second concerns a generalization, one that calls for adjustments of a weighted average of exchange rate and interest rate instruments, so designed to be effective whether the economy is, or is not, in a liquidity‐trap situation. Finally, the third topic concerns political‐economy aspects of policy, which tend to incline against the use of the activist systems.     

Interest Rate Flexibility and the Open Economy*

The objective of the paper is to analyze the importance of institutional changes in the financial system for the efficacy of monetary policy and in particular for the connection between the balance of payments (capital account) and monetary policy. Particular institutional developments studied include the emergence of certificates of deposit and the removal of interest rate ceilings in 1973. The result established, using a general equilibrium model, is that the degree to which transactions in the capital account of the balance of payments offset a domestic monetary expansion is greater in a regime of market-determined interest rates than in a regime of administered rates.     

Hysteresis in an Open Economy Model

This paper explores the properties of an open economy model in which real exchange rate overshooting has a permanent impact on the rate of unemployment via a hysteresis mechanism. The magnitude of this effect depends on the slope of the short-run Phillips curve, the speed with which expectations adjust in the labour market, and on the speed with which capacity adjusts to changes in capacity utilisation. However, it does not depend on how open the economy is, although the dynamics of the adjustment process (including the extent of the initial jump in the exchange rate following a change in monetary policy) do depend on this factor.
