On the semantic approach to econometric methodology

In recent research, Davis (2005) has introduced the semantic conception of theories as a means of studying the differing practices of the Textbook and LSE approaches to econometric modelling. In this paper, Davis' (2005) use of the semantic view is examined, with close attention paid to the stated roles of the semantic notions of 'model dimensions' and 'bridging assumptions'. While comments concerning the latter are of a supportive nature, some concerns are raised in relation to Davis' use of model dimensions.
