Question

Agreement and disagreement among economists.

Answer 1

Answer:

a) differences in scientific judgments.

b) Tariffs and import quotas generally reduce economic welfare.

Explanation:

Manuel is an economist who believes in classical approach of economy whereas Poornima is an economist who believes in Keynesian approach.  

The Classical economics supports the idea of law and quantity theory of money. The Classical economist believes that economy is capable to achieve its natural level of real GDP by using available resources. Classical theory focuses on monetary policy to manage its money supply in an economy.

Keynesian economic theory states that government should boost demand to increase the growth. This theory believes in expansionary fiscal policy.  

Manuel and Poornima disagree due to difference in their scientific judgment. They are arguing over the type of policy need to keep the economy running smoothly.

The Import and Tariffs quotas generally reduce the economic welfare. Most of the economist agrees to this proposition. Tariffs when increased then economic growth of a country slows down.
