Hi all I am trying to update variable D(t) using equation D(t+1)=(1+n)*G(t)+(1+r)*D(t) so that D(t+2)=(1+n)*G(t) +(1+r) *((1+n)*G(t)+(1+r)*D(t)) Thanks for your help set t /0*300/ ; scalar r /0.05/ n /0.0148/ ; Variables G(t) D(t); G.fx(t)=0.5; D.fx('0')=0.01; D.fx(t+1)=(1+n)*G.l(t)+(1+r)*D.l(t); di...

Hi all,

Is there a way for Conopt to give me all optimal solution within a bounded set?

Thanks,
Fabio

Hi,

You could use NEOS Server, https://neos-server.org/neos/. You submit your GAMS file on their website and they run the program for you. After, you can download the results and open them on your GAMS software.

Kind regards,
Fabio

Hi all,

I am using MCP to solve a model. If I solve for t=5 (MCP5), it gives me a solution. If I solve for t=10 (MCP10), it gives me an error 'infeasible'. Could someone help me solve the problem?

Thanks,
Fabio

Hi Renger,

Thanks for your reply.

Hi all, I need to write a loop to solve the equations below. utility(ii,t)$(ord(t) le card(a)-1).. u=e=(1/(1-1/gamma))*sum(a,ss(a)*((1+beta(ii))**(1-ord(a)))*(1-1/gamma)*log((c(ii,a,t)**(1-1/rho)+alpha*l(ii,a,t)**(1-1/rho))**(1/(1-1/rho)))); asset(ii,a,t).. as(ii,a,t)=e=(1+r)*as(ii,a-1,t-1)+w(t)*e(i...

Hi all, I'm using MCP to solve firm's profit maximization as recommended by a paper. output(t).. Y(t)=e=(kappa*[epsilon*K(t)**(1-1/sigma)+(1-epsilon)*L(t)**(1-1/sigma)]**[1/(1-1/sigma)])-0.5*psi*power(I(t)/K(t)-(n+delta),2)*K(t); wage(t).. (1+cr)*w(t)=e=((1-epsilon)*kappa*L(t)**(-1/sigma)*(epsilon*K...

Hi Petros,

I did that and it worked.

Thanks,

Hi all, I've got an error in equation utility(ii,t).. u=e=(1/(1-1/gamma))*sum(a,S(a)*(beta**(ord(a)-1))*([c(ii,a,t+(ord(a)-1))**(1-1/rho)+alpha*l(ii,a,t+(ord(a)-1))**(1-1/rho)]**(1/(1-1/rho)))**(1-1/gamma)); I have already defined the lower bound c.lo(ii,a,t)=0.01 and l.lo(ii,a,t)=0 If I remove ord(...

Hi Renger,

Thanks for the recommendation, I will try it and see what happens.

Cheers,
Fabio
