ABSTRACT
Discovering the nature of air pollution has been an important part of the history of smog in Southern California. Hence smog is frequently referred to as photochemical smog. In conjunction with the trade-based economy, Los Angeles surpassed San Francisco as the West Coast's leading port. With this influx came yet another wave of decentralization—a pattern already established by the intra-war development of Southern California. The defense industries would remain as the mainstay of the economy of Southern California through the 1950s. During the period between World War I and World War II the economic and superstructural basis for the subsequent development of Los Angeles' political economy was created. Stability in several models is based on the stability of the rules of the game: in the functionalist model it is the stability of the political economy of Southern California as a whole; for the utilitarian model it is the stability of the individual market.
