The cost of tickets to the 2000 Sydney Olympic Games "could be the highest ever for a summer Olympics," according to AROUND THE RINGS. The cost will depend on "how many tickets are actually put up for sale -- and how much SOCOG realistically expects to make from ticket sales," but an analysis of numbers from a '98 SOCOG media guide shows that ticket prices could average $54. But since SOCOG's estimated number of tickets it will sell has risen in the past few months, the average could end up being A$57, which would be "about equal" to Atlanta's price in '96 (ATR,3/12). BREAKING EVEN: Although expenses for the Nagano Games "far exceeded initial estimates," officials say they "appear to have generated enough revenue to offset the costs," according to an AP report. Nagano government spokesperson Hidehiko Arai said operating expenses are "expected to reach" $843.4M, but that costs will be "offset by strong ticket sales and higher-than-expected revenue from sponsorship contracts" (AP/BOSTON GLOBE, 3/18).
