This study formulates an information measure for changes in asset values and applies the formulation to farmland values in the United States for 1960 to 1999. The results indicate that changes in asset values contained significant information following the Russian wheat sale in the early 1970s and the financial crisis in agriculture in the mid 1980s. Further, information about preceding year's asset values largely explains the regional distribution of current year's farmland values.
