Ben has been named a Furer Fellow in the Department of Economics for 2018-2021. The second can be understood as we notice that not listing all relevant causes - incompleteness in the first sense — can be implemented by way of formulating idealizing premises that neutralize some causes and so exclude them from theory or model. Modern theory of economic growth focuses mainly on two channels of inducing growth through expenses spent on research and development on the core component of knowledge innovations. Suppose now that for some investors the monotonicity property is violated (they prefer less money to more money, hence they are strongly irrational) or alternatively suppose that they do not know how to exploit the certain profit in case of option mispricing (hence they are inefficient).
