1. The problem of externalities

Exchange rate volatility

In some cases, the exchange rate can cause economic problems. For example, countries in the Euro were not able to change the value of their currency against other Eurozone members. Because countries like Greece and Portugal had higher inflation rates, they became uncompetitive. Exports fell, and they developed a large current account deficit. The overvalued exchange rate caused a fall in economic growth.

On the other hand, a rapid devaluation can cause different problems. For example, when the price of oil fell, oil exporting countries saw a decline in export revenues, leading to a fall in the value of the currency. A rapid devaluation causes the price of imports to rise and causes both higher inflation and lower growth. A difficult problem for policymakers to deal with.

Development economics

Developing economies face similar economic problems, but any issue is magnified by low GDP and high levels of poverty. For example, unemployment in a developing economy is more serious because there is unlikely to be any government insurance to give a minimum standard of living.

Poverty cycle. Some developing economies may be stuck in a poverty trap. Low growth and low saving ratios lead to low levels of investment and therefore low economic growth. This low growth and poverty cause the low savings and investment to be continued.
