What are two basic services that investment banks provide in the economy?

Investment banks primarily provide two key services: underwriting and advisory services. Underwriting involves helping companies raise capital by issuing stocks or bonds, ensuring that these securities are priced correctly and sold to investors. Additionally, they offer advisory services for Mergers and Acquisitions, guiding firms through the complexities of these transactions to maximize value and minimize risk. Together, these services facilitate capital flow and support corporate growth in the economy.
