The mobility of workers is an important source of regional dynamics, but the effect of mobility on regional productivity growth is not straightforward, as some firms tend to win while others lose from mobility. In the present paper, we argue that the co-worker networks across plants that are...

The degree of uncertainty in a worker's productivity is affected by many factors, such as worker-employer matching, technology, and macroeconomic conditions. Not surprisingly, uncertainty in labor productivity (ULP) varies across firms, industries, and economies. The question arises: How do...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. An equilibrium model of growth and firm evolution designed to clarify the role of worker reallocation in the growth process is studied. We show that it...
