Brazil’s President Dilma Rousseff will make changes in her government’s policies and advisory team if re-elected to the post, the president said Wednesday. Speaking to business leaders at the National Confederation of Industries, Ms. Rousseff re-iterated a previous pledge to overhaul her administration to improve industrial policies.”Obviously, with a new government, there’s necessary updating and new policies and teams,” she told the group.  Ms. Rousseff didn’t say Wednesday which advisors she might replace or which policies she would change if re-elected. The president, however, admitted that  the government needed to do more to improve the economy. “I don’t want to give the impression that I think everything that can be done has been done,” she said. “I think, in fact, that industry is going through a very complex situation.” According to data released by Brazil’s IBGE statistics institute last week, the economy contracted by 0.6% in the second quarter, putting the country into a technical recession. At the same time, Brazil’s industrial output contracted by 2.8% in the first seven months of the year. Meanwhile, according to recent local opinion polls, Ms. Rousseff, of the Workers’s Party, trails Socialist Party challenger Marina Silva in major electoral regions such as São Paulo and Rio de Janeiro, and could stand to lose to Ms. Silva by as much as 10 percentage points in runoff vote. Brazil is scheduled to hold a first-round presidential vote on Oct. 5.
