Dutch Disease - Diagnosis

Diagnosis

It is rather difficult to definitively say that a country has Dutch Disease because it is difficult to prove the relationship between an increase in natural resource revenues, the real-exchange rate, and a decline in the lagging sector. There are a number of different things that could be causing this appreciation of the real exchange rate. The Balassa-Samuelson effect occurs when productivity-increases affect the real exchange rate. Also important are changes in the terms of trade and large capital inflows. Often these capital inflows are caused by foreign direct investment or to finance a country's debt.

Similarly, it is difficult to show what is causing a decrease in the lagging sector. A case in point is the Netherlands. Though this effect is named after the Netherlands, economists have argued that the decline in the Dutch manufacturing industry was actually caused by unsustainable spending on social services.
