The unemployment rate fell mostly because of a decline in the size of the labor force.

One-time factors
The main takeaway from the jobs report is that there were so many special one-time factors during the September sampling period that this should not move the needle at the Fed or among investors who still expect growth to advance at or above 4% in the second half of the year. That rate is more than double the long-term growth trend in the economy of 1.8%. This jobs report should not alter the Federal Reserve’s plan to begin slowing its pace of monetary accommodation through its monthly asset purchase program. The Fed expects an acceleration in hiring toward the end of the year that will be accompanied by an improvement in the labor force participation rate, which in September was 61.6%. In our estimation, the Fed is well positioned to announce its plan to pare back its $120 billion per month in asset purchases at its November meeting by roughly $15 billion per month ($10 billion in Treasury securities and $5 billion in mortgage-backed securities). That reduction would put the asset purchase program on target to end next July.
