摘要：The paper demonstrates that random coefficient models can be estimated by maximumlikelihood if they are specified as generalized least squares models. The paper uses maximumlikelihood estimation on a random-coefficient, meat-demand system. Statistical tests show thatprice elasticities are random, but expenditure elasticities are not. The statistical tests allow oneto count the number of factors that cause randomness without requiring one to know what theyare. There appear to be only two factors that make the price elasticities random.
