The international expo field, whose start began with the Crystal Palace Exhibition 1851 in London, England, reaches across the globe to incorporate hundreds of expositions, from those sanctioned by the BIE, to those of horticultural, regional, and national scope. They represent events, not unlike the Olympics, of international cooperation and competition, and have been at the forefront of some of the most important historical achievements of the past 150 years, from the first public displays of the Edison's phonograph and Bell's phone to the more recent displays of technology in oceanagraphy.

However, over the past thirty years, it has become more and more apparent that these events should not be viewed in a feasibility study vacuum, with any new proposal started from virtual scratch for its projections. Many experts within this field, including presidents and secretary-generals of the Bureau of International Expositions, have decried the need for some unbiased view, a broad based unbiased assistance that will make these events more viable in the present and future. The accumulation of data that was necessary for this study, as well as the economic decision model that sprung from that, represents over 10 years of work of JDP ECON, plus the labor and assistance of several hundreds experts in the field.

JDP Econ is currently using the World's Fair Decision Model as the basis for in house publishing projects, including

The Vancouver Games: A Spectacular Choice: Following in the Footsteps of Canada's Expo and Olympics Success

JDP ECON is now developing its EXPOcheck series of reports, providing an unbiased, independent review of approved events in the coming years, beginning with Zaragoza and Expo 2008.  These independent attendance dynamics reports based on the World's Fair Decision Model are great additions to the information provided by official sources and may be useful to public planners, exhibitors, concessionaires, media, and others interested in the upcoming events.
