WASHINGTON — US Vice President Kamala Harris plans to roll out a new set of economic policies this week that aim to help Americans build wealth and set economic incentives for businesses to aid that goal, three sources with knowledge of the matter said.

The new policies, which have not been previously reported and could be announced in Pittsburgh on Wednesday, come as undecided voters continue to ask for more information about how Harris would help them economically if she were elected president in November, including those in critical swing states, the sources said.
