Volcker's correspondents in the Chronological Correspondence series are mostly private citizens employed in banking, real estate, and other fields. The letters express these individuals' views on various economic concerns, especially monetary policies and the impact of interest rates on housing and other industries. Many of Volcker's responses to these individuals contain elements from form letters. The series also includes letters to Federal Reserve staff that are predominantly administrative in nature, replies to invitations, and letters to U.S. congressmen, mainly responses to requests that the Federal Reserve comment on specific economic issues. Researchers should note that this series contains Volcker's outgoing correspondence only.
