In 1977, Stigler and Becker hypothesised that ‘tastes neither change capriciously nor differ importantly between people’. In an interregional context, this implies that irrespective of differences in income and geography, consumers in different regions are similar. Studies conducted 25 years ago using data for Australian states found support for this hypothesis. However, due to the changing ethnic composition of the population in the states of Australia, differences in consumption patterns between states are emerging. Using recent regional consumption data and demand models, we investigate in this study whether there are regional disparities across the six Australian states, and find that there are in fact differences.

模拟澳大利亚的区域消费模式*

1977 年，Stigler 和 Becker 假设“人与人之间的口味既没有反复无常的变化，也没有显着差异”。在跨区域背景下，这意味着无论收入和地域差异如何，不同区域的消费者都是相似的。25 年前使用澳大利亚各州的数据进行的研究发现支持这一假设。然而，由于澳大利亚各州人口的种族构成不断变化，各州之间的消费模式差异正在显现。使用最近的区域消费数据和需求模型，我们在本研究中调查了澳大利亚六个州之间是否存在区域差异，并发现实际上存在差异。
