Studies of auction prices for artworks typically relate the conditional moments of a single realised price distribution either to characteristics of the artist, the artwork and the auction or to pre‐sale information. Using data from the Australian Art Sales Digest for the 100 best‐selling Australian Indigenous artists over the period 1987–2014, we use finite‐mixture models to understand heterogeneity in auction prices. Our results complement the existing literature by identifying new ways in which factors previously used in the literature may be related to price heterogeneity in a differentiated market such as that for Australian Indigenous art.

澳大利亚土著艺术家拍卖价格分布的异质性

艺术品拍卖价格的研究通常将单个已实现价格分布的条件时刻与艺术家、艺术品和拍卖的特征或预售信息联系起来。使用澳大利亚艺术销售文摘中 1987 年至 2014 年期间 100 位最畅销澳大利亚土著艺术家的数据，我们使用有限混合模型来了解拍卖价格的异质性。我们的结果通过确定文献中先前使用的因素可能与差异化市场（例如澳大利亚土著艺术）中的价格异质性相关的新方式来补充现有文献。[作者摘要]
