FINANCIAL MARKET MODELS. A LOGICAL ASSESSMENT
FINANCIAL MARKET MODELS. A LOGICAL ASSESSMENT

Summary/Abstract: The paper aims to analyze, from a logical and epistemological perspective - the possibility of knowledge, on the one hand, and the testability of knowledge, on the other hand - the main models developed and (some of them) operationalized in the financial transactions market. In this context, it is proposed to classify these models according to the „target” pursued and, based either on the statements of the creators of the models in question or (if such statements are missing or only implicit in theoretical developments), according to the fundamental principle (or the basic mechanism) specific to the models examined. The paper also examines the typology of the concepts of financial market efficiency, as it results from the logical and epistemological examination of the models in question. Finally, the paper analyzes the empirical testability (in the sense of Popper's falsifiability) for each of the financial market model considered (a number of six such models).
