Final answer:
The price of a good can increase when it crosses national borders due to taxes, tariffs, and customs duties imposed by the importing country.
Step-by-step explanation:
The price of a good can increase when it crosses national borders due to the imposition of various taxes, tariffs, and customs duties by the importing country. These additional costs are usually passed on to the consumer, resulting in a higher price for the imported good. The amount of increase depends on the specific policies and trade agreements between countries.
For example, if a good is subject to a 20% tariff when crossing a national border, the price of the good would increase by 20%. This means that if the original price of the good was $100, the new price after crossing the border would be $120.
