 One of the latest incarnations of the Auerbach-Kotlikoff model – a paper by Hans Fehr, Sabine Jokisch, and Laurence Kotlikoff entitled "Dynamic Globalization and Its Potentially Alarming Prospects for Low-Wage Workers," includes five regions (the U.S., Europe, Japan, China, and India), six goods, region-specific fiscal policy and demographics, and the endogenous determination of the pattern of specialization.In 1984, Kotlikoff wrote a fundamental paper entitled "Deficit Delusion", which appeared in The Public Interest.This was the first of a series of papers and books (see, e.g., Generational Accounting and Generational Policy) by Kotlikoff, including work with co-authors, showing, via examples, that in economic models featuring rational agents, "the" deficit is a figment of language, not economics.
