jewelry, stone, gem, luxury cars, etc. The demand for such goods increases
with the increase in the consumer’s income.
4. Consumers’ tastes and preferences: Consumer’s Tastes and preferences play
a vital role in determining a demand for a product. Tastes and preferences often
depend on the lifestyle, culture, social customs, hobbies, age and sex of the
consumers and the religious sentiments attached to a commodity. The change in
any of these factors results in the change in the consumer’s tastes and
preferences, thereby resulting in either increase or decrease in the demand for a
product.
5. Advertisement Expenditure: Advertisement is done to promote sales of a
product. It helps in stimulating demand for a product in four ways; by
informing the prospective consumers about the availability of a product, by
showing its superiority over the competitor’s brand, by influencing the consumer’s
choice against the rival product and by setting new fashion and changing tastes
of the consumers. The effect of advertisement is said to be fruitful if it leads to the
upward shift in the demand curve, i.e. the demand increases with the increase in
the advertisement expenditure, other things remaining constant.
6. Consumers’ Expectations: In the short run, the consumer’s expectation with
respect to the income, future prices of the product and its supply
position plays a vital role in determining the demand for a commodity. If the
consumer expects a high rise in the price of the commodity, shall purchase it
today at a high current price so as to avoid the pinch of the high price in the
future. On the contrary, if the prices are expected to fall in the future the
consumer will postpone their purchase with a view to avail benefits of lower
prices in the future, especially in case of nonessential goods.
Likewise, an expected increase in the income increases the demand for a
product and vice-versa. Also, in the case of scarce goods, if its production is
expected to fall short in the future, the consumer will buy it at current higher
prices.
7. Demonstration Effect: Often, the new commodities or new models of an
existing product are bought by the rich people. Some people buy goods due to
their genuine need for them or have excess purchasing power. While some
others do so because they want to exhibit their affluence. Once the commodity is
in very much fashion, many households buy them not because they have a
genuine need for them but their neighbors have purchased it. Thus, the purchase
made by such people arises out of feelings as jealousy, equality in society,
competition, social inferiority, status consciousness. The purchases made
on the account of these factors results in the demonstration effect, also called
as Bandwagon Effect.
