First, how can we "measure" whether our labor market is strong? In your answer, please put emphasis on the unemployment rate, the labor force participation rate, underemployment, etc

First, how can we "measure" whether our labor market is strong? In

your answer, please put emphasis on the unemployment rate, the labor

force participation rate, underemployment, etc. That said, according to

the text, we should get paid our "marginal revenue product" (MRP) -

what does this depend on? How can we use what we know about the MRP to

explain why wages differ from one job to the next in our economy? What

are some variables that are related to the MRP...? In other words, the

MRP is a bit too general, so if we were to examine earnings related to

other variables, what would they be?
