On the estimates we have come up with in our report for increases in GDP and the number of jobs, if you do simple math and divide the number of jobs created by the investments in infrastructure, it comes up to a very expensive per job cost. The immediate stimulative effect is not that great, because the government is injecting money into an economy that's already running at full capacity. What this does is that it just creates overheating in the economy. Therefore, the timing might not be the best if the goal is to stimulate the economy immediately; it's just putting even more fire in an economy that's not red hot but operating at full capacity. While it can be helpful for longer term growth, the immediate impact is not to stimulate growth; it's to provoke inflation.
