When it comes to discussing the relationship between economics and other disciplines, the latter that are spontaneously considered are other sciences, either pure or applied. However, the fine arts are also disciplines whose relation to economics might be considered, even if only for the sake of mutual clarification. And, among the fine arts, architecture is the one which is most closely related to economics for various reasons that I will discuss below, for it is this relatively unexpected kinship between these two disciplines that I intend to explore. While I will emphasise the significance of these relations, I am quite aware that, since architecture is an art and economics is a science, or, at least, aims to be a science, any similarity between them must be interpreted with this important difference kept in mind.
