what is shift in demand curve?what does it mean?can someone please give me a detailed explanation of the same?

A shift in the demand curve is when people stop wanting something. They stop buying it. So, a shift in the demand curve. It could be the opposite of course

A demand curve is a relationship between price and quantity consumed. So for each alternative price, the curve can tell you how much is the desired consumption. Something that changes this entire relationship is represented as a shift in the demand curve. For example, after the change, there is now more desired consumption for the same price. What could cause a shift? The factors held constant in constructing the demand curve. For example, an decrease in price of batteries is going to increase the demand for remote-controlled toys (fall in price of complement).

A shift in the demand curve is caused by anything other than price(of that specific good). For example, price of related goods, income, consumer preferences, etc. Take price of related goods. Related goods can either be substitute goods (goods that can be substituted for each other, ex. pepsi and coke) or complement goods(goods that go together, ex peanut butter and jelly)

ok, Peanut butter and jelly are complement goods. If the price of peanut butter goes up, people are not going to buy it as much, less demand for it. Therefore, the demand for jelly is going to decrease. So on a demand curve for jelly, the demand will decrease, or shift to the left.

I hope this helped.. the way the demand curve shifts depends on the factors.

If the price of pepsi goes up, the demand for coke increases.

With income there are normal goods (anything from like a dvd player to a car), and then inferior goods (which would be like generic food and stuff). If income increases, the demand for normal goods increases, and the demand for inferior goods decrease. And everything is always vice versa also.

Good luck
