This study explores the impact of remittances on household spending and investment decisions in Rajshahi Division, Bangladesh. It is based on a cross-sectional survey of 235 remittance-receiving households. For analyzing survey data from households that receive remittances, the research employs multiple regression models to examine spending behaviors. The sample includes households randomly selected from Pabna, Sirajganj, and Kushtia districts. The study focuses on key factors such as financial literacy, migration duration, and income levels to understand their influence on remittance utilization. Findings indicate that most households prioritize consumption over investment. The regression results reveal that financial literacy and remittance amount significantly and positively affect household investment ratio, while migration duration is the strongest predictor of business investment percentage. Interestingly, income levels do not appear to have a significant moderating effect on remittance-driven investment behavior. This study shows how financial knowledge promotes beneficial remittance expenditure. The study's unique focus on migration duration and business investment illuminates remittance-driven financial behavior. Based on these findings, the study recommends promoting household-level financial literacy programs and supporting long-term migrants' investment initiatives to improve the productive use of remittances. Such targeted measures can help maximize remittance benefits for household stability and local economic development, especially in rural regions like Rajshahi Division.
