If the images don't come through, here's a quick description.
Here's a chart of compensation per hour increases from Greg Mankiw's blog (see right side menu for a link). This shows a sharp drop in the rise in compensation per hour starting at around 2000, roughly coinciding with the beginning of the decrease in labor force participation. What caused the drop-off of wage increases? Is it related to the change in participation? Previous inflection points in this chart came when labor force participation was still increasing or steady.
