that higher prices and MLDAs reduced not only the fraction of youths who drank beer infrequently but that the fractions of youths who consumed beer fairly frequently and frequently declined more in both absolute and percentage terms than did the fraction of infrequent drinkers when prices rose. The investigators also conducted similar analyses for different drinking levels among the youth, including light drinkers who consumed one or two cans of beer, fairly heavy drinkers who consumed three to five cans, and heavy drinkers who consumed six or more cans on a typical drinking day. Again, the fractions of fairly heavy and heavy drinkers declined more in both absolute and percentage terms than did the fraction of light drinkers in response to price increases.
