UPDATE: Sunday Inquirer column here. Obama said this weekend he's against a second stimulus, first needs time.

EARLIER: "The U.S. needs another stimulus package because President Barack Obama’s initial $787 billion plan hasn’t been implemented fast enough," markets scholar and Nobel laureate Robert Shiller of Yale tells Bloomberg LP here. New York University economist Nouriel Roubini, who takes credit for predicting the credit market blow-up, thinks "more spending is necessary to avoid stagnation like Japan’s in the 1990s."

"The U.S. traditionally hasn’t had to deal with long-term joblessness. During the last 30 years, Americans who were thrown out of work took an average 15.8 weeks to find new positions. In June, the average duration of unemployment was 24.5 weeks, the longest since records began in 1948. The number of people collecting unemployment benefits reached a record 6.88 million in the week ended June 27."
