Concept:A larger market is a benefit of regional integration, not a challenge faced by ECOWAS.
Explanation:ECOWAS is the Economic Community of West African States, created to promote trade and cooperation.
Member countries face many real problems in achieving this goal.
Political instability and weak governance are common obstacles in the region.
Poor transport and communication infrastructure also slow down integration.
Many national economies are weak and not diversified enough, which creates another difficulty.
Colonial heritage and the existence of other similar organizations further complicate ECOWAS efforts.

It gives member states access to more consumers and expanded trade opportunities.
Therefore, a larger market is an opportunity, not a problem.
