Net growth in Drezner household labor pool

My congratulations to the Dan Drezner family on their new arrival, Lauren!  I'm sure he's cross-charted the additional expenditures, long-term trends in the Drezner household labor pool, and marginal incremental utils involved in this acquisition.  May his negative forecasts prove exaggerated, his positive forecasts understated, and his and his spouse's coefficient of contented parentivity ever exhibit a strongly positive delta!
