Question

which is more damaging to the economy cost-push inflation or demand-pull inflation Why?

Answer 1

This can't be answered. It depends on the underlying causes of the inflation and the time frame.

A demand-pull inflation induced by poor government policy (such as printing money) is very bad for the economy, both in the short term and long term. (U.S. policy in the paying for the Vietnam War is a classic example)

On the other hand, a demand-pull inflation because the local product has become very popular and commands good prices in trade making the local population richer is far more benign. Ditto if the increase in demand is due to increased productivity (and hence true wealth), more even distribution of income (the poor spend a higher percentage of their income than the rich), etc.

A cost-push inflation due to the rising long term cost of energy or some other important resource can greatly damage the economy.

On the other hand, a short term rise in the cost of an essential resource, or the long term rise in a resource for which substitutes can be of net benefit to the economy. (Consider the response to the rise of gold prices, from the early 70s to the spike around January '80)
