Advertising and food, drink and tobacco consumption in the United Kingdom: a dynamic demand system
研究了1963-1996年间英国广告对非耐用品消费需求分布的影响，发现价格是主要影响因素，广告对改变产品间需求模式作用有限。
Abstract This paper tests for the influence of advertising on the inter‐product distribution of consumer demand for non‐durable goods and services in the UK, 1963–1996. The long‐run demand for seven categories of non‐durable products is modelled through an advertising‐augmented version of the almost ideal demand system (AIDS), which is incorporated into an error‐correction model to allow for short‐run dynamic adjustments to long‐run equilibrium positions. Model estimates confirm that the restrictions of price homogeneity and symmetry appear to be consistent with the data, yield measures of the various types of demand elasticity that are in general plausible, confirm the strong influence of prices on the allocation of consumer expenditure, but find little evidence to support the hypothesis that advertising has the power to effect marked changes in the inter‐product pattern of consumer demand in the UK.
