Prior research has established the important role of startups and fast-growing young businesses in job creation and employment growth in the U.S. economy (Haltiwanger, Jarmin, and Miranda, (2010)). New firms and young businesses account for about 70 percent of gross job creation and disproportionately contribute to net job creation. The experimentation and dynamism of startups and young businesses also contribute to productivity growth (see, e.g., Haltiwanger (2012)). While the contribution to job creation and productivity is increasingly well understood, relatively little is known about the characteristics of the jobs generated by startups and young businesses. We use newly released data from the QWI using the firm size and firm age measures developed from the Business Dynamics Statistics (BDS) to shed light on characteristics of jobs at young businesses. We focus on three key characteristics of jobs -- job creation, the churning of workers, and earnings per worker.
