This study attempts to examine the contribution of the service related sector in the economic growth of Bangladesh during the period of 1973-2017. We used the Gross domestic product (GDP) as a measure of economic growth for Bangladesh. Sub-sectors of service-related sector have been used as explanatory variables along with some control variables. In this study, we apply various econometric tools like as Unit Root test, Granger causality test, ARDL Bound test, Error correction model and Cointegration test to investigate the causal relationship and the intensity of the relationship between the service related sector and gross domestic product or economic growth. Granger causality test shows the presence of uni-directional granger causality from the service related sector to gross domestic product. The error correction term implies that the short-run disequilibrium is adjusted with the long-run at the speed of 17 percent. Moreover, ARDL bound approach indicates the service related sector and gross domestic product growth are correlated both in short-run and long-run. The result shows that 1% expansion in service-related sector will result in an increase of 0.64% gross domestic product or economic growth in short-run and 0.75% of GDP in the long-run . Contribution/ Originality:This Study Contributes to the existing literature by examining both short-term and long-term contribution of the service sector on economic growth of Bangladesh using the ARDL Bound test. This study also examines the intensify of that relationship.

This paper pursues to establish a connection among the nominal interest rate, the money market, and the inflation rate in Bangladesh using monthly time series data from June 2005 to March 2019. Because some data are stationary at the level and others are stationary at the 1st difference, the ARDL model is applicable for checking the link. There is a strong positive short-term and long-term relationship between inflation and nominal interest rates, suggesting that Bangladeshi data support the Fisher hypothesis for that time. For this study, the T bill, the call money rate is used as a measure of the money market. The research indicates that regulators should concentrate on call money rates in short-term and T-bill and call money rates in the long-term to control Bangladesh's nominal interest rate.
