Spatial price transmission in the onion markets of Bangladesh: An application of NARDL approach.

As the price of local onions is greatly impacted by the price of imported onions at these two levels of the supply chain, the goal of this study was to ascertain whether onion prices in Bangladesh are transmitted asymmetrically at the wholesale and retail levels. To analyze asymmetry, the study employed the nonlinear autoregressive distributed lag (NARDL) model in the short and long run using monthly time series data from January 2006 to December 2020. The NARDL model captures the effects of both positive and negative shocks in the short as well as in the long run.

A tree based eXtreme Gradient Boosting (XGBoost) machine learning model to forecast the annual rice production in Bangladesh.

In this study, we attempt to anticipate annual rice production in Bangladesh (1961-2020) using both the Autoregressive Integrated Moving Average (ARIMA) and the eXtreme Gradient Boosting (XGBoost) methods and compare their respective performances. On the basis of the lowest Corrected Akaike Information Criteria (AICc) values, a significant ARIMA (0, 1, 1) model with drift was chosen based on the findings. The drift parameter value shows that the production of rice positively trends upward.

Empirical assessment of onion supply chain constraints in Bangladesh: A pre-covid to covid situation.

In Bangladesh, Covid-19 has wrecked devastation on people's livelihoods and economies. It began with supply chain disruptions affecting a variety of agricultural products, particularly perishable ones. Onion, the most consumed species in Bangladesh and Asia is also fallen into that category.

Assessing the factors and constraints for value chain development of dairy food products in Bangladesh.

The dairy sector in Bangladesh has shifted from subsistence to commercial and enterprise-driven due to the increasing demand of milk and milk products. In this context, this study was conducted to explore the different participants in dairy value chains and their role in the production, processing and marketing of dairy products. This study addresses the constraints faced by these participants and the factors influencing the value chain efficiency as a case study from Bogura districts of Bangladesh.
