STEP-BY-STEP ANSWER:
Step 1: Identify the major problems caused by asymmetric information, namely adverse selection and moral hazard.
Step 2: Understand that financial intermediaries pool funds from multiple savers, which diversifies risk and increases the ability to screen borrowers.
Step 3: Explain that intermediaries employ screening and monitoring processes to assess borrower risk and ensure proper use of funds.
Step 4: Discuss how additional tools like collateral and restrictive covenants further mitigate the risks posed by asymmetric information.
Final Answer: Financial intermediaries reduce the challenges of asymmetric information by pooling risks, screening for creditworthiness, and enforcing measures such as collateral requirements and restrictive covenants.
