Abstract We study a real small open economy with two key ingredients (1) partial segmentation of home and foreign bond markets and (2) a pecuniary externality that makes the real exchange rate excessively volatile in response to capital flows. Partial segmentation implies that, by intervening in the bond markets, the central bank can affect the exchange rate and the spread between home- and foreign-bond yields. Such interventions allow the central bank to address the pecuniary externality, but they are also costly, as foreigners make carry trade profits. We analytically characterize the optimal intervention policy that solves this trade-off: (1) the optimal policy leans against the wind, stabilizing the exchange rate; (2) it involves smooth spreads but allows exchange rates to jump; (3) it partly relies on “forward guidance,” with non-zero interventions even after the shock has subsided; (4) it requires credibility, in that central banks do not intervene without commitment. Finally, we shed light on the global consequences of widespread interventions, using a multi-country extension of our model. We find that, left to themselves, countries over-accumulate reserves, reducing welfare and leading to inefficiently low world interest rates.

This paper evaluates the monetary policy response of Malaysia's central bank and the nature of monetary transmission mechanism in the 1990s when the exchange rate was on a managed float and the capital account was open. Structural vector autogression analysis is employed to evaluate how the central bank sets short term interest rates taking into consideration the constraints faced in adjusting the policy instrument to shocks to the economy. The impulse response functions and the variance decomposition indicate that the central bank preferred to use foreign exchange intervention rather than interest rate to stabilize the ringgit exchange rate. The results suggest that a sustained high level of interest rates would have caused a prolonged and deep contraction in output during the East Asian financial crisis.

We propose a new dynamic transition analysis on the basis of a small open economy dynamic stochastic general equilibrium model. Our proposed analysis differs from existing static and conventional dynamic analyses in that shifts from a fixed exchange rate regime to a basket peg or a floating regime are explicitly explored. We apply quantitative analysis, using data from the People's Republic of China and Thailand, and find that both economies would be better off shifting from a dollar peg to a basket peg or a floating regime over the long run. Furthermore, the longer the transition period, the greater the benefits of shifting to a basket peg regime from a dollar peg regime owing to limited volatility in interest rates. Regarding sudden shifts to a desired regime, the welfare gains are larger under a shift to a basket peg if the exchange rate fluctuates significantly.

The paper analyses the long-run (steady-state) output and price stability of a small, open economy which adopts a “crawling-peg” type of exchange-rate regime in the presence of various kinds of random shocks. Analytical and simulation results suggest that with the exception of money demand shocks, an exchange rate policy which involves a relatively higher rate of indexation of the exchange rate to price level is likely to lead to the worsening of price stability for all types of shocks. On the other hand, the impact of adopting such a policy on output stability depends on the type of the shock; for policy shocks to the exchange rate and shocks to output demand, output stability is worsened whereas for the shocks to risk premium of domestic assets, supply price of domestic output and the wage rate, better output stability is achieved in the long run.

This paper analyzes the impact of the inflation and the world interest rate on the Indonesian economy and the effectiveness of the Indonesian central bank policy to adopt the domestic macroeconomic fluctuation.Assuming Indonesia as a small-open economy, the Stuctural Vector Autoregressive Model is utilized on the monthly data during the periode of 1999: 1 – 2004: 12 covering the main domestic macroeconomic indicator (output, price, money supply, interest rate and the exchange rate) and the world oil price and world interest rate as the disturbance source.The analysis provides 2 main results, first, the international variables do have impacts on the domestic variables fluctuation, implying the fragility of the domestic economy due to the external shock, second, the monetary policy is effective on supporting the economic growth and stabilizing the price level. However, the Bank Indonesia policy to stabilize the international shock via the exchange rate channel, contributes to a higher impact of the international shock on domestic interest rate.Keywords: monetary policy, business cycle, SVARJEL Classification: E52, E32, C32, F41

This paper analyzes the effectiveness of monetary transmission channels in Ukraine since the National Bank of Ukraine (NBU) transitioned to inflation targeting and after the central bank established its new approach to monetary policy implementation. The authors conclude that the central bank has sufficient control over short-term interest rates in the interbank market and that it uses them to influence other financial market indicators. At the same time, further transmission via the interest rate channel is constrained by weak lending and the banking system’s slow post-crisis recovery. The exchange rate channel remains the most powerful avenue of monetary transmission. After the NBU switched to a floating exchange rate and an active interest rate policy, its key rate became a means of influencing exchange rates. The exchange rate channel’s leading role is expected to gradually decrease but remains important, as is typical for small open economies.
