A Peterson Institute of International Economics study on the TPP trade agreement shows it would reduce growth in the U.S. manufacturing sector by a fifth, according to this report in the NYT. Workers incomes and job losses in manufacturing are a key concern for voters and account for the surge in polls for Trump and Sanders in the U.S. presidential election of 2016. All four leading candidates Clinton, Sanders, Trump and Cruz oppose the TPP agreement. Congress will wait till after the election to decide. This is a big issue today because about 5 million jobs have been lost in 1977-2014, according to the Alliance for American Manufacturing. The Peterson study predicts job losses of 50,000 a year, yet another study by Tufts University predicts job losses of 450,000 a year. Another study by the Economic Policy Institute study shows other damaging effects such as labor's share of national income declining from the TPP.
