To answer James Ahaikpor: I am sorry if my elliptical expression   
"inflationary pressure" was confusing. I did not want to go in detail into a   
first year lecture but here is a bit more detail that now seems called for.   
If more income is earned and spent, that adds to aggregate demand (or as   
Keynes would have put it Aggregate Consumption Expenditure). That has a   
potential effect on both employment and the price level. How the effect is   
divided between the two will depend on where the economy is in relation to   
its potential (or full employment) income/output,.or as some text books put   
it will, where the economy is on its aggregate supply curve . The key point   
is that if there is an increase in paid employment, there will be effects   
operating through increased market demand while if there is an increase in   
unpaid employment, ceteris paribus, there will be no such effects -- which   
is why, if we are interested in such macro variables as employment and the   
price level, we want to measure only monetary transactions.
