I can do no better than to quote my colleague Jim Hines from his public finance seminar announcement this week:
This Thursday is Thanksgiving, the annual holiday that commemorates the 1817 publication of David Ricardo's On the Principles of Political Economy and Taxation, which started the field of public finance. The holiday expresses our gratitude for the opportunity to study taxation. It is customary to feast on that day, in celebration of the absence of excise and sales taxes on food prepared at home.
To whatever readers remain after my sad posting performance this semester: Enjoy the day!
