    Climate Change Effects on Shrimp Production in Bangladesh: Economic Insights for Declining Export Revenues
    (Premier University, Chattogram, 2026-03) Dey, Sudip
    Shrimp, often called to as the "white gold" of Bangladesh, ranks as the second most exported product after ready-made garments. The shrimp industry is crucial for increasing national income, generating employment, and earning foreign currency for Bangladesh, but it is adversely affected by various climate-related factors. Applying unit root tests, co-integration, ordinary least squares (OLS) methods, and one-way ANOVA, the study evaluates how climate factors influence shrimp production and assesses whether foreign exchange earnings have significantly increased with the rise in shrimp production from 1990 to 2022. The results reveal that moderate humidity, greenhouse gas emissions, mean temperature, and rising Ganges water levels positively affect shrimp production, with greenhouse gas emissions, mean temperature, and water level increases showing significant results at the 1 percent level of significance. Conversely, precipitation and areas affected by flooding have adverse effects on shrimp production, also significant at the 1 percent level. Additionally, despite the rise in shrimp production, export earnings have not increased significantly, although they have a long-run association. The research identifies several factors contributing to the decline in export revenue, including limited product variety, high production costs, global economic downturns, decreased global demand, rising domestic consumption, trade barriers, inadequate export subsidies, dishonest trading practices, lack of quality control, reliance on extensive farming, the Covid-19 pandemic, devaluation of domestic currency, and inefficient supply chain management. This study proposes key strategies to enhance shrimp export revenues, including diversifying into value-added shrimp products, increasing the production of vannamei shrimp, integrating modern technologies, ensuring the availability of healthy fingerlings, adopting semi-intensive farming practices, improving supply chain management, modernizing processing facilities, boosting incentives for exporters, and maintaining political stability.

    Does Foreign Trade Affect Inflation in Bangladesh? An Econometric Exercise
    (Premier University, Chattogram, 2023-04) Dey, Sudip
    Nowadays, inaction is a burning issue in Bangladesh. The purpose of this article is to analyze whether exports and imports affect inflation and whether current inflation is influenced by the previous year’s exports and imports. Utilizing annual time series data from 1986 to 2020, the study applies the augmented Dickey-Fuller (ADF-) test, the Phillips-Perron (PP) test, Johansen’s cointegration test, the ordinary least squares (OLS) method, the fully modified OLS (FMOLS) method, and the lagged regression technique. The econometric results of the study show that exports have a positive, significant impact on inflation. Imports, on the contrary, have a positive but insignificant impact on inflation. Furthermore, the results of the lagged regression show that the previous period’s exports have a negative impact on the current period’s inflation, while the previous period’s imports have a positive impact, though both effects are insignificant. Research indicates that providing incentives and subsidies to major export industries, trade surplus, devaluation of the domestic currency, import prices, distortion of the trade balance, and improvement in terms of trade are the foreign trade-related factors that cause inflation in Bangladesh. The study suggests that the government of Bangladesh should create a competitive trade environment to reduce export-related inaction and lower its tariff rates and non-tariff trade restrictions to encourage other nations to export goods and services to us.
