On Broadway: A consortium of New York theater community members joined together Tuesday to form a plan to reduce ticket prices and costs so that more plays can be produced on Broadway. The plan, which will become effective Sept. 1, was announced in a New York press conference by the League of American Theaters and Producers, and the three major theater operating organizations --Jujamcyn, Nederlander) and Shubert, as well as representatives from several unions and guilds. By reducing salaries and royalty payments, one-act plays with small casts can be produced for $400,000 under the plan, and offered to the public at prices ranging from $10 to $24.
