A study sees fast growth in the state economy.

The California economy will grow 4.5% this year and 4.2% in 1987, outstripping the estimated U.S. growth rate of 3%, according to a forecast by Security Pacific National Bank. Despite problems in the agriculture and energy sectors, the state will produce $557 billion in goods and services. State consumer prices will rise only about 4.1% during 1987, chiefly as a result of drastically lower energy prices. Southern California will benefit more than the northern part of the state, which is suffering weaknesses in electronics and non-residential construction, according to the annual report by the bank’s economics group.
