摘要：First-order, homogeneous, stationary Markov models are used to compare patterns of adjustment among Florida fresh grapefruit packers between the 1970/71-1983/84 and 1987/88-1999/00 periods, and 1970/71-1994/95 and 1995/95-1999/00 periods, respectively. Despite sweeping aggregate trends impacting fresh produce markets, there was insufficient evidence to identify significant differences in the patterns of adjustment in the packing sector during the later time periods. Comparisons with actual firm numbers are indicative of an industry near equilibrium. While individual firms enter and exit the different states, currently there are no profound structural changes pointing to major concentration.
