What came first, the chicken or the egg?  The difference between Keynes and Say is about what same, what drive the economy supply or demand.  If you do not know these two guys, I recommend looking them up real quick, it will shed some light on what the government is trying to do now.

For the last few decades the Keynes argument has been followed, increase money supplier, increase demand, speed up the economy.  Or do the opposite to slow down the economy.  This is what the government does when it lowers or raises the interest rates (a certain interest rate).  It is also the goal of the increase in infustructure speeding which is being talked about now.  In the past this has worked pretty well to control changes in the business cycle.  Hopefully since it is clear that this is what the government will use now, lets hope it works in the future too.

The other way of thinking is from Say, which thinks that supply is the more important factor.  When the economy slows down, it is not due to a lack of demand, but a shift in what is supplied.  In other words, the wrong items are being supplied, and a shift is taking place to stop producing the current items, and produce the other items.  If this is true, we are pretty much at full employeement at all times, only have structural unemployement which involves moving to different jobs, with different skill sets.  It this correct, could be, there are lots of places hiring for the people with the right skills, even as unemployement grows.  You will end up getting in the descussion what is full-employement.  We all know it should not be 0%, there will always be some unemployeement, but I think it is agreed that it is not 10%.  Also, I would say the number is moving, at some times, the shift in production is low, at others, it is high, I think between 3 and 8 is a reasonable range.  If this is true, the government is doing the wrong thing, instead of working to increase demand in certain areas, let production shift naturally, and move towards equalibrium.  Shift production artificially will only result in additional production of goods where they market does not think they should be produced, which is really the will of the people in a free market.  This will result in a decrease in long-term prosperity, with prosperity being people having the maximum amount of utility.

Not to get to deep, it is important to know these two ways of thinking to better understand what the government is trying to do currently.  We many never know for sure if demand drives supply or if supply drives demand, but it is something good to think about so we can try to limit our impact on long-term productivity as much as possible.  By the way, I would also speculate that sometimes demand drives, and other times supply drives…it is a social science.
