WASHINGTON (AP) — From Wall Street trading floors to the Federal Reserve to economists sipping coffee in their home offices, the first Friday morning of the month typically brings a quiet hush around 8:30 a.m. eastern as everyone awaits the Labor Department's crucial monthly jobs report. But with the government shut down, no information was released Friday about hiring in September. The interruption in the data has occurred at a particularly uncertain time, when policymakers at the Federal Reserve and Wall Street investors would need more data on the economy, rather than less.
