Very few studies have focused on Donald Davidson’s work on decision theory: the emphasis has rather been put on his groundbreaking work on action theory and philosophy of language. Nevertheless, Davidson is, in many respects, a major author of experimental economics, which developed in the United States in the 1950s. Besides, it is worth noticing the significance of decision theory in Davidson’s work—as evidenced by his numerous articles in which he deals with both his research at Stanford in the 1950s3 and his attempt, based on Richard Jeffrey’s research, to build a ‘unified’ theory of action and language that would overcome the weaknesses of decision theory.
