Southern California’s economy continues to slow as the housing downturn has been full swing for a few quarters. However, the following industries have been growth drivers:  retail trade, transportation, warehousing and logistics, administrative and support, leisure and hospitality, and professional, scientific and technical services. Even with falling single-family home prices, tighter mortgage underwriting standards, and increasing residential notices of default and foreclosures, the industrial real estate markets continue to remain stable in sales prices and rental rates.  Though industrial economics remain flat, transactions numbers and absorption values are half the numbers from a year ago.
