Forget about declining circulation and the cost of newsprint—The Wall Street Journal is adding a more lucrative feature to its portfolio. The newspaper is expanding the number of conferences it produces, according to The New York Times. Four years ago, the paper created a successful technology conference called "D: All Things Digital." Now the paper plans to add several more, the first of which, "Eco:nomics," will focus on business and the environment. The goal is to attract 200 senior executives at a ticket price of $3,495 each. The lineup will include C.E.O.s of companies including Wal-Mart and Dow Chemical. California governor Arnold Schwarzenegger has also been invited to participate but has yet to commit. Executives at The Journal told The Times that the events can yield several hundred thousand dollars in profit.
