May 2009: Two new FAQs:
I want to be warned (or get a fatal error) if a coefficient becomes negative. How can I do that?
Can GEMPACK ever tell that a simulation has no solution?

Sep 2008: We prepared some tips on using GEMPACK with the command line and with BATch files.

June 2008 : GEMPACK 10 is released, after several months testing at CoPS and selected other sites.

June 2007: Mark Horridge and Ken Pearson named as two of the inaugural five members of the GTAP Hall of Fame

April 2007: After 24 years developing GEMPACK, Ken Pearson has reduced his commitment, moving towards a part-time, research-oriented involvement. He has passed on the position of Director, GEMPACK Software, to Mark Horridge, who will assume overall and day-to-day responsibilities, assisted by Dr. Michael Jerie (software and support) and Louise Pinchen (Business Manager). Ken will remain in the background to solve more difficult problems.
These re-arrangements are unlikely to affect GEMPACK users much. For the future, we are confident in being able to offer modellers the same steady improvements in software and the same meticulous support and documentation that Ken Pearson and Jill Harrison (predecessor of Michael Jerie) provided for many years.

January 2007: We put together some notes to help people choose a new PC suitable for running longer GEMPACK simulations.

September 2006: Jill Harrison retires. Jill has made huge contributions to GEMPACK software, support and teaching. Her legacy will continue well into the future. We wish her well as she begins the next phase of her life.

June 2006: The Centre of Policy Studies welcomes new staff member Dr Michael Jerie. Michael joins CoPS from the Department of Mathematics at La Trobe University. He takes up the position of Research Fellow (Software Support/Developer).

June 2006: Ken Pearson and Mark Horridge presented a paper on parallel processing with GEMPACK at the 9th Annual Conference on Global Economic Analysis, held in Addis Ababa (Ethiopia).
