Quarterly Projection Model For Vietnam A Hybrid Approach For Monetary Policy Implementation

We present a newly developed Quarterly Projection Model (QPM) for Vietnam. This QPM represents an extended version of the canonical New Keynesian semi-structural model, accounting for Vietnam-specific factors, including a hybrid monetary policy framework. The model incorporates the array of policy instruments, specifically interest rates, indicative nominal credit growth guidance, and exchange rate interventions, that the authorities employ to meet the primary objective of price stability. The calibrated model embeds a theoretically consistent monetary transmission mechanism and demonstrates robust in-sample forecasting accuracy, both of which are important prerequisites for the richer analysis and forecast-based narratives that support a forward-looking monetary policy regime.

The paper develops a small New-Keynesian FPAS model for Vietnam. The model closely matches actual data from 2000-2014. We derive an optimal monetary policy rule that minimizes variability of output, inflation, and the exchange rate. Compared to the baseline model, the optimal rule places a larger weight on output stabilization as the intermediate target to achieve inflation stability, while allowing greater exchange rate flexibility. We analyze the dynamics of key macro variables under various shocks including external and domestic demand shocks and a lift-off of U.S. interest rates. We find that the optimal monetary policy rule delivers greater macroeconomic stability for Vietnam under the shock scenarios.

The paper describes the Quarterly Projection Model (QPM) that underlies the Bank of Ghana Forecasting and Policy Analysis System (FPAS). The New Keynesian semi-structural model incorporates the main features of the Ghanaian economy, transmission channels and policy framework, including an inflation targeting central bank and aggregate demand effects of fiscal policy. The shock propagation mechanisms embedded in the calibrated QPM demonstrate its theoretical consistency, while out-of-sample forecasting accuracy validates its empirical robustness. Another important part of the QPM is endogenous policy credibility, which may aggravate policy trade-offs in the model and make it more realistic for developing economies. Historical track record of real time policy analysis and medium-term forecasting conducted with the QPM – as a component of the broader FPAS analytical organization – establishes its critical role in supporting the Bank’s forward-looking monetary policy framework.

Viet Nam has made remarkable economic progress over the past decades, sustaining high economic growth. The economy has also proven resilient to shocks, including the COVID-19 pandemic.

Against the background of a strong economic performance over the last quarter of a century, Peru has been hit by multiple shocks in the last several years. Adequate policies and very strong policy frameworks have made the economy resilient. Following a steep decline in 2020 at the outset of the pandemic and a rapid recovery in 2021, growth slowed significantly in 2022 as the policy stimulus was withdrawn and external and financial conditions deteriorated. Recent political developments suggest that the new government needs to work across the political spectrum to create broader political consensus, reduce uncertainty, ease social tensions, and boost growth.

Spurred by an impressive vaccination drive, the economy is rebounding from a severe pandemic wave. The government successfully maintained fiscal, external, and financial stability. Nonetheless, the labor market recovery is lagging, with sizeable underemployment, small and medium sized enterprises remain vulnerable, problem loans are rising, real estate and corporate bond market risks are elevated, and the pandemic exacerbated longstanding structural challenges.

Over the past two decades, many low- and lower-middle income countries (LLMICs) have improved control over fiscal policy, liberalized and deepened financial markets, and stabilized inflation at moderate levels. Monetary policy frameworks that have helped achieve these ends are being challenged by continued financial development and increased exposure to global capital markets. Many policymakers aspire to move beyond the basics of stability to implement monetary policy frameworks that better anchor inflation and promote macroeconomic stability and growth. Many of these LLMICs are thus considering and implementing improvements to their monetary policy frameworks. The recent successes of some LLMICs and the experiences of emerging and advanced economies, both early in their policy modernization process and following the global financial crisis, are valuable in identifying desirable features of such frameworks. This paper draws on those lessons to provide guidance on key elements of effective monetary policy frameworks for LLMICs.

Belarusian authorities contemplate transiting to inflation targeting. The paper suggests a small structural model at the core of the forecasting and policy analysis system. A well-researched canonical structure of Berg, A., Karam, P. and D. Laxton (2006) is extended to capture specifics of Belarusian economy and macroeconomic policy. The modified model’s policy block reflects a monetary targeting regime and allows for transition from it to an interest-rate-based framework. Adding wages, directed lending and dollarization allow for studying implications of activist wage policy, state program lending, and dollarization for macroeconomic stability and the strength of the policy transmission mechanism.
