Abstract A sample of 2,185 Ghanaian households from the GLSS6 was examined using a latent class model of structural heterogeneity in a linear regression framework to assess their fish consumption patterns. The results suggest that Ghanaian households fall into two consumption categories, namely “traditional” and “non-traditional” households, though there is some overlap between the two household groups. Demand for fish is price inelastic in traditional households and approximately unitary elastic in non-traditional households. In traditional households, fish is complementary to poultry but a substitute for red meat. Among non-traditional consumers, fish is complementary to poultry but a substitute for red meat and pork. While price is a major concern for traditional consumers, taste, diversity, health and nutrition are more important to non-traditional consumers. Traditional consumers are in the forest region while the non-traditional consumers are in the Savannah areas.

加纳家庭鱼类消费的决定因素分析

摘要 在线性回归框架中使用结构异质性的潜在类别模型对来自 GLSS6 的 2,185 个加纳家庭样本进行了检查，以评估他们的鱼类消费模式。结果表明，加纳家庭分为两个消费类别，即“传统”和“非传统”家庭，尽管这两个家庭群体之间存在一些重叠。对鱼的需求在传统家庭中是缺乏价格弹性的，而在非传统家庭中则近似于单一弹性。在传统家庭中，鱼是家禽的补充，是红肉的替代品。在非传统消费者中，鱼是家禽的补充，是红肉和猪肉的替代品。虽然价格是传统消费者的主要关注点，但口味、多样性、健康和营养对非传统消费者更为重要。传统消费者在森林地区，而非传统消费者在萨凡纳地区。
