The article talks about the magnitude of the hit which ranges from 1% - 25%.
The Port of Los Angeles alone generates 919,000 regional jobs and $39.1 billion in wages and tax revenues each year. Los Angeles ports handle about 40% of all the container traffic in the United States. There are a total of 3 million employees in industries related to port operations. Studies project Los Angeles ports will lose between 1% and 25% compared to existing levels of trade.Well, 1% is rather unimpressive. So what one can glean (or guess) from this is probably a couple of things:
1) Some portion of CA shipping will be lost. Take it form the middle and say 10%.
2) Growth will probably take the biggest hit.
But from articles I've ported before, it's still faster to unload as soon as possible and transfer to rail/truck. So, I'm guessing time sensitive merchandise such as clothing will be shipped through CA. Large items such as lawnmowers and TV sets, etc will be transported through the new widened Panama Canal.
