Introduction

The economy of North Sumatra is a significant contributor to the overall economic growth of Indonesia. However, the region's economy is vulnerable to various external and internal shocks, including monetary policy changes. This study aims to analyze the impact of monetary shock on the economy of North Sumatra, specifically focusing on the period from 2005 to 2012. The study uses a combination of qualitative and quantitative analysis to provide a comprehensive understanding of the relationship between monetary policy and economic development in the region.

Methodology

The study uses a Vector Autoregression (VAR) model to analyze the impact of monetary policy on the economy of North Sumatra. The VAR model is a statistical technique that allows for the analysis of the relationships between multiple time series variables. In this study, the VAR model is used to examine the relationships between inflation, interest rates, exchange rates, and GDP in North Sumatra.

Impact of Inflation and Exchange Rate on GDP

The results of the study show that inflation and exchange rates have a significant impact on GDP in North Sumatra. The variant decomposition test reveals that the movement of GDP is most influenced by inflation and exchange rates, while interest rate variables tend to fluctuate. This suggests that high inflation and exchange rate instability can suppress regional economic growth.

Inflation can reduce people's purchasing power, leading to lower domestic consumption, which is the main driver of GDP. Exchange rate fluctuations can cause uncertainty for business actors, affecting investment and ultimately GDP. Therefore, the stabilization of these two factors is crucial for the sustainability of economic growth in North Sumatra.

The Relationship Between Economic Variables

The results of the Granger Causality test show that there is no causal relationship between GDP and BI interest rates. This indicates that changes in interest rates are not always followed by changes in GDP, suggesting that economic actors in North Sumatra are not fully responsive to monetary policy determined by Bank Indonesia.

However, there is a one-way relationship between GDP and the exchange rate, showing that changes in the exchange rate can significantly affect GDP. The relationship between GDP and inflation also does not show causality, illustrating the complexity of the regional economy, where several factors may affect economic growth in an indirect way or through other channels.

Conclusion

In conclusion, the study finds that monetary shock has a significant impact on the economy of North Sumatra. The stabilization of inflation and exchange rates is crucial for maintaining economic stability in the region. Monetary policy must be more responsive to changes in local economic conditions to have a positive impact on GDP growth.

Further research is necessary to explore various other variables that might also affect economic dynamics in North Sumatra. Comprehensive analysis will help decision makers in formulating policies that are more targeted and effective. By understanding the impact of monetary shock on the economy of North Sumatra, policymakers can develop strategies to mitigate the effects of external and internal shocks, promoting sustainable economic growth in the region.

Recommendations

Based on the findings of this study, the following recommendations are made:

Stabilize inflation: The government and Bank Indonesia should prioritize stabilizing inflation to maintain economic stability in North Sumatra.
Maintain a stable exchange rate: The government and Bank Indonesia should work to maintain a stable exchange rate to reduce uncertainty for business actors and promote investment.
Develop targeted monetary policy: Monetary policy should be more responsive to changes in local economic conditions to have a positive impact on GDP growth.
