Income expansion path -IEP- traces all the best (utility-maximizing) choices a consumer makes as income changes. The IEP slopes up if a good is a normal good The IEP is downward sloping if a good is inferior An Engel curve plots all the best choices a consumer makes against INCOME. It is an income-quantity relationship If an Engel curve is upward sloping, a good is normal; downward sloping indicates an inferior good.
