Economic Theory

In general, an excise tax will decrease the quantity of the item that consumers demand. This occurs for the simple reason that an excise tax increases the price of the product, making it less attractive to consumers.

Explanation:so then it would go down.

c. It would probably cause the supply curve to shift to the left.

Explanation:

These taxes are imposed on certain products that are specially produced to be sold in the local market. Business people have a responsibility of understand how the taxes work and how they may affect the supply of commodities.

However, the taxes do not affect all products equally because of the countermeasures that are in place to respond to the taxes so that the supply will not be affected

There the excise duty is likely to make the curve to move to the left because the excise duty increases the product price
