Research and teaching in financial economics very often assumes that the efficient market hypothesis is verified. Nonetheless, financial markets are still very far from reaching substantial levels of efficiency. Moreover, different perspective of market efficiency can be subsumed. In this paper, we provide a clearcut taxonomy of the different nuances of financial markets efficiency, useful for economic research and teaching. We also argue that scholars should necessarily disclose in advance the perspective of market efficiency assumed for the research analysis or teaching purposes and discuss the limitations in the inference that can derive.

Abstract
Research and teaching in financial economics very often assumes that the efficient market hypothesis is verified. Nonetheless, financial markets are still very far from reaching substantial levels of efficiency. Moreover, different perspective of market efficiency can be subsumed. In this paper, we provide a clearcut taxonomy of the different nuances of financial markets efficiency, useful for economic research and teaching. We also argue that scholars should necessarily disclose in advance the perspective of market efficiency assumed for the research analysis or teaching purposes and discuss the limitations in the inference that can derive.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
