Changes in the location of employment and ownership: Evidence from California

We use the National Establishment Time-Series database to describe shifts in the geographic dispersion of employment and ownership of firms. Focusing on data on business establishments in California, and establishments anywhere in the United States that are owned by firms headquartered in California, we find shifts in the operations of businesses headquartered in California to other states. However, this shift has been offset by increased employment in the state by firms headquartered elsewhere, resulting in California's share of national employment holding quite constant. The evidence points to increasing geographic dispersion of firms' operations, especially in industries with lower communication costs.
