The researchers studied how small-scale palm fruit processors in Ghana can increase their profits. They found that focusing on the joint production of palm oil and its by-products is important for maximizing profit. Factors like gender, education, experience, and access to credit influence profit margins. It's crucial to consider all products in a joint production system to accurately calculate profits. Encouraging women to stay in school longer and providing more credit opportunities can help boost profits for small-scale palm oil processors.
