Brazuca, my friend:
I finaly found somthing where I strongly disagree with you.
The money supply is one area where the government has tremendous responsibilities. The money supply is a basic part of the infrastructure of an economy, as are roads, a court system for interpreting contracts, a police department for protecting the peace, etc ....
The boom/bust cycle has always existed in economic markets. Human psychology plays a major roll in this. You might find it fascinating to study the price of tulips in Holland during the later half of the 18’th century.
With modern economies, a government has a few obvious levers to push/pull in order to reduce the extremes of the boom/bust cycle.
An overly simplified explaination goes like this:
If the economy is getting over heated, it will drastically over produce, at which point there will be a collapse, as business cannot sell that which they have in their warehouses. To prevent the economy from overheating, the government attempts to make it more difficult for a business to borrow money (by raising interest rates). A government also does this by raising taxes, which are then put to good use, but usually in a very inefficient way, further pulling money out of the economy.
If the economy is spiraling downward, a government will attempt to encourage business to invest by lowering interest rates and cutting business taxes. A government will also cut personal taxes in order to encourage people to buy things to heat up the economy. This is what has been happening for the past couple of years in the USA. The economy slipped into recession during the last couple of months of the Clinton administration. Bush and Greanspan have been focused on getting the economy out of recession using the above techniques.
As an economy does this, it effects the exchange rate with other world currencies. However, this is usually a secondary effect. It is usually not the primary intent (This is true, usually for the largest economy in the world, the USA).
