Hi, I am trying to solve a problem that can be expressed as a quite simple symbolic system, but somehow it seems that Mathematica cannot handle it.It says that "This system cannot be solved with the methods available to Reduce". It cannot be solved via maximize either (since lambda1 is a constant).

Does anyone have any ideas, suggestions or have faced the same problem? Thanks in advance!!! The system is..


Profit1[SL_,SH_]:= Lambda1(PL-c[SL]*SL)+(1-Lambda1)(PH-c[SH]*SH)
PL=ThetaL*SL

PH=-ThetaH*SL+PL+ThetaH*SH

Profit1[SL_, SH_]

Reduce[Profit1'[L0, H0]\[Equal]0 && Profit1''[L0,H0]<0, {L0,H0}, Reals]

Answer: "This system cannot be solved with the methods available to Reduce"

Thanks
Gui
