 An important discussion from economics needs mentioning, namely the question whether models of doxastic preference change are capable in principle to represent all preference changes. This question originates with an important paper by Stigler and Becker (1977), who argued that a wide range of phenomena which are commonly thought of as preference changes—like addiction, habitual behaviour, fashions and the effects of marketing—can be explained by stable, well-behaved preferences. In a rather informal fashion, they argue that such explanations involve only changes in information (more precisely: prices and income), while leaving preferences intact. As a result of this, economists largely abandoned the discussion of preference change, believing that all preference change phenomena can be explained in this way. Prima facie, their proposed explanations exhibit important similarities to the discussed accounts of doxastic preference change. The results from that discussion, which show that models of doxastic preference change are subject to relatively strong constraints, may therefore put doubt on the orthodox position in economics that models of doxastic preference change are capable in principle to represent all preference changes.
