Breve comentarios en Notes for Liberty sobre el argumento que los desastres naturales son buenos para la economía porque hacen crecer el PBI.
Every time there is a natural disaster old economic fallacies make their appearance. And they are usually always the same. In particular, the argument that a natural disaster is good for the economy. This should make little sense. Wealth is not created by destroying things. A natural disaster destroys wealth, doesn’t create it. I doubt anyone affected by a hurricane would argue that he is better off after the natural disaster than before.
The argument that an event such as a natural disaster is good for the economy rests in the positive impact seen in GDP (as is argued) after the natural event. If GDP increases, then the economy is doing better. But this is a misreading of GDP. This variable is a flow of wealth, it is not a stock of accumulated wealth. It is possible that wealth creation (flow) increases at the same time the stock of wealth is decreasing. And this is what happens during a natural disaster.
