Achange in money income of consumers will

It depends on which way it goes. If the supply increases and prices stay the same, the disposable income increases in a meaningful way. That condition will cause the Fed either to raise interest rates, or the price of goods will respond to the increased demand or a third alternative could be that manufacturers will increase production (not very likely but it could happen).

If the supply of money decreases (by people being laid off for example) then the opposite of all the events listed above will or can occur. The fed could become more accommodating and lower interest rates. The price of good will decrease unless manufacturers increase their inventory (which not really healthy for an economy) or they could decrease production which will further decrease the labor force which will put the economy in an endless vicious cycle -- one no one wants.
