Our house is all electric and we average 750 KWH a month. I don't know anyone in our area with a bill that low that doesn't use natural gas on top of it. Our monthly minimum with Entergy appears to be around $45.
The overall natural rate of unemployment will then be affected by changes in the demand or supply in these different segments of the overall labor market and by changes in the composition of the aggregate labor force. Several major changes in recent decades have affected labor supply and demand.
Some level of unemployment will always exist for no other reason than that there always will be some people who are between jobs or just starting out their careers. These people are unemployed not because there is a shortage of jobs in the market, but because finding a job takes time. Such temporary spells of unemployment are referred to as frictional unemployment. The combination of these factors brings about a long-term average around which the unemployment rate tends to fluctuate, called the natural rate of unemployment (NRU).
