I've noticed that a lot of data online seems to measure a non-US country in USD. This seems odd to me, because doesn't that mean that US fiscal/monetary policies, politics, and economics would affect the GDP numbers for this other country?
From what I understand, the reason for measuring in USD is because it factors in the country's fiscal policy. If the country's government runs a deficit and borrows money, then that is somehow factored in when the GDP is converted to USD. But doesn't that also factor in things unrelated to the given country?
I would have thought that measuring Real GDP would be a better metric for factoring in things like deficits and borrowing. If the government borrows, I that increases inflation, and therefore, measuring Real GDP would factor that in. Is that not the case?
