Nick, my intention is far more than simply defining what efficiency
is. Even If we are dealing with Economic theory regarding producer who
is a profit maximizer (under a competitive market framework), there
are certain rules to the game: you cannot simply estimate TC as a
function of the output, because both variables are endogenous. To make
it even more complex, note that financial markets are highly
noncompetitive, and suffer from other problems, such as information
problems, moral hazard, adverse selection etc. This is a whole
separate world, and if you would like to make a serious research work,
which merit some value, the first stage is to study the subject
