Impulse Response of External Debt Stock and Gross Capital Formation on Economic Growth in Bangladesh: Var Model, Granger Causality and Variance Decomposition Analysis

Purpose: This study employs an annual time series data set from 1987 to 2018 gathered from the World Development Indicators (WDI), 2021 to analyze the properties of external debt stock on financial progress(proxied by economic growth) in Bangladesh. Methodology: The objectives are determined using a variety of econometric techniques, including the Phillips-Perron (PP) unit root test, Var model, Johansen co integration test, Impulse Response Function (IRF), Variance decomposition function, and Granger causality test. The get the result of the Phillips-Perron (PP) unit root test which indicates the stationarity of all the variables at the initial difference. Findings: There is an expectant impact on financial progress (proxied by Gross Domestic Product Per capita) in Bangladesh, according to the short run Var model with the two independent variables External Debt Stock (proxied by public debt) and second lag of Gross Fixed Capital. Block Exogeneity/ Wald Tests and Johansen Co-integration test show that both lnEDS and lnGCF have a strong constructive impact on Bangladesh's financial progress in the short as well as long run. Pairwise, Granger Causality also indulgence the Bi-directional causality between lnGDPPC and lnEDS and Uni-directional causality from lnGCF to lnGDPPC. The influences of lnEDS and lnGCF on lnGDPPC are rising in the long term, showing that both variables are significantly exogenous on the dependent variable. Practical Implication: Bangladesh is now a fast-growing economy with several mega projects for infrastructural, human, and technological advancements such as roads, train, power, education, health, information technology, gas, and energy. External debt service and gross capital formation are crucial for Bangladeshi economic growth. The government should establish a priority aim for long-term economic growth by implementing suitable measures to control, maintain, regulate, and stabilize inflation at a reasonable level. Originality/Value: In a developing country, Savings within the country are insufficient to support investment for financial progress, according to the dual-gap theory and the Keynesian theory of public debt. As a result, bridging this gap for the required level of investment and achieving targeted economic growth will necessitate a bigger inflow of foreign aid or external borrowings. That’s why this study is very important. Limitations: Some limitations of this study include the absence of recent data with the factors. Also numerous factors can influence Bangladesh economic growth for instances, remittances, exchange rates and foreign direct investment all have a crucial impact on GDP growth.
