This study estimates the impact of the price of alcoholic beverages on latent dimensions of current alcohol dependence and abuse. A three-part econometric model is used to estimate the impact of price on three latent dimensions (factors). For heavier drinking, the estimated price elasticity is -1.325 (P = 0.027); for physical and other consequences of drinking, -1.895 (P = 0.003); for increased salience of drinking, -0.411 (P = 0.339). For a single latent factor characterized simply as dependence/abuse, estimated price elasticity is -1.487 (P = 0.012). These results suggest that higher prices for alcohol reduce important dimensions of current alcohol dependence and abuse.
本研究估计了酒精饮料价格对当前酒精依赖和滥用潜在维度的影响。采用三部分计量经济模型来估计价格对三个潜在维度（因素）的影响。对于重度饮酒，估计的价格弹性为-1.325（P = 0.027）；对于饮酒的身体及其他后果，为-1.895（P = 0.003）；对于饮酒显著性增加，为-0.411（P = 0.339）。对于一个简单定义为依赖/滥用的单一潜在因素，估计的价格弹性为-1.487（P = 0.012）。这些结果表明，酒精价格上涨会降低当前酒精依赖和滥用的重要维度。
