Dengan asumsi ceteris paribus, turunnya harga ikan lele dapat menyebabkan…

1. Jumlah lele diminta bertambah (movement along the demand curve)
2. Jumlah lele ditawarkan berkurang (movement along the supply curve)
3. Berkurangnya permintaan barang substitusi (shifting the demand of substitution good to the left)
4. Naiknya permintaan barang komplementer (shifting the demand of complementary good to the right)

tlg dikoreksi jika ada kesalahan. trims
