Tariffs can help domestics producers but can hurt consumers. Governments impose tariffs on imported goods and services to make them more expensive to consumers. Tariff provides revenue to the government and give a price advantage to domestic producers. While it protects domestic industries, it can also hurt foreign producers.
With the GDP per capita, this depends on the wealth and the population of a country. For somewhere such as the Arab Emirates, they have a small population, but a fair amount of wealth, so this then increases the GDP. The situation is similar with Kuwait. Iran has also been affected by War, meaning that some of the infrastructure will hav been destroyed, and that people would not be able to work and make money, which is then something that will have a direct impact on the GDP. With countries such as Jordan and Sudan, As far as I'm aware, they are relatively poor countries with a high population, meaning that the GDP will be lower and split between more people,therefore, meaning that it will be low. With regards to A). Iran is a country that has definitely been affected by this, following the war. B) A large majority of the countries that have been mentioned are also predominately desert, so where there is not people that are making money, this is something that is then not contributing to the GDP. Countries such as Kuwait and UAE also have large oil reserves, and this is something that can contribute to wealth hugely, and the smaller the population, the less people the GDP has to be spread between, and therefore, this increases it. With environmental disasters, these can have a huge impact, and the amount of money that is being made is also greatly reduced, and the expenditure is also increased, which is also something that can decrease the GDP.
Hope this helps you!
