1. The problem of externalities

Balance of payments/current account deficit

A current account deficit on the balance of payments means an economy is importing more goods and services than it is exporting. To finance this current account deficit, they need a surplus on the financial/capital account. For many modern economies, a small current account deficit is not a problem. However, some developing economies have experienced a balance of payments crisis – where the large deficit has to be financed by borrowing, and this situation usually leads to a rapid devaluation of the currency. But, this devaluation increases the price of imports, reduces living standards and causes inflation.
