This graph above shows what difference indirect taxes would create. By using indirect taxes, the supply curve is most likely to shift to the left which is from S1, to S2, as there will be a smaller decrease in quantity but an increase in price. In the gap between S1 and S2 there is a gap which shows how much tax is paid. The tax paid is what causes the price to go up, leading to the quantity going down. Therefore the quantity bought would be from Q2 and the price would be from P2. The larger the gap between S1 and S2, the higher the price of the indirect tax. Rules and regulations is also a good method which can affect the consumption of demerit good. This is because it generates limits which apply to the good. These limitations can sometimes be hard to control. For example, there can be underage tobacco buyers who buy them secretly; this is something very difficult to control. Rules can be added to this to help. If there was a law put in place saying underage buyers of tobacco will be fined a big amount if caught then many people would stop buying as they would be scared to face the consequences. This is a way in which the method will be very effective as it lowers the consumption of the demerit good. In this graph you can see that there is a sold line which shows the limited amount of quantity there is for a good. For example, there would be a limited amount for what age people can buy cigarettes and/or how many can be bought. When this gets put in to place, the demand curve would shift upwards, causing the price to become higher. This is a good way in causing the demerit goods to be consumed less as the quantity would be fixed.
In conclusion I think that there are many ways in which demerit goods consumption can be reduced but it can be a very difficult job. Demerit goods will never be goods that consumers would stop consuming such as the tobacco example. Finally, out of both of the methods I have explained I think indirect tax would be the best way to decrease the consumption of the demerit good. This is because it is more likely to have a bigger and better affect than the rules and regulation due to the price becoming more expensive than before. If the government uses indirect taxes everyone will have to pay, for goods like tobacco or things that are even worse. On the other hand, tobacco is very addictive causing people not to care whether the price has changed for the good or for the bad. The advantage of using an indirect tax to reduce consumption of demerit goods is that everyone pays them. Whether they are constant tobacco buyers or not. This could put off the new comers of smoking. As for rules and regulations, it is a harder way to keep track of the consumption and not many people would get caught if simple rules were put in. it would also be really expensive to hire police and guards up 24/7 in each road checking if the rules are being followed.
