ECON1002 Lecture Notes - Lecture 2: Red Meat, Inferior Good, Disposable And Discretionary Income
Document Summary
T he income effect: is the change in demand for a good or service caused by a change in a consumer"s purchasing power resulting from a change in real income. Changes in purchasing power can result from income changes, price changes or currency fluctuations. Price decreases increase purchasing power, allowing a consumer to buy a better product or more of the same product for the same price. However, different goods and services experience these changes in different ways. for example, Normal goods are those whose demand increases as people"s incomes and purchasing power rise. Inferior goods are goods for which demand declines as consumers real incomes rise. This occurs when a good has more costly substitutes that see an increase in demand as the society"s economy improves. However, the income effect results in consumers spending more or less in general and does not necessarily indicate that they will buy higher or lower value goods.
