MRG - Market Failure and the Role of Government Overview
Market Failure and the Role of Government Overview
Introduction
The need for government intervention is typically in response to some sort of market failure. That is, sometimes markets do not function the way we believe they should or they do not produce efficient outcomes. In such cases, the government may be needed to intervene and correct for the market failure. In this module, we will consider several types of market failures and the steps the government may take in response. In addition, you will become familiar with general arguments in favor of and in opposition to government intervention.
