Dollar index ticks up after US productivity data

NEW YORK: The dollar added gains briefly against a basket of currencies on Tuesday as revised figures on US productivity and labor costs in the first quarter supported a view that the slack in the jobs market is diminishing at a gradual pace.

The measure of the greenback versus the euro, yen, sterling and three other currencies was up as much as 0.9 percent shortly after the revised data. It was last at 93.907, little changed from late Monday.
