# LoadError: MethodError: no method matching LinearRationalExpectations

Dear Dynare Team,

Hope you are well.

I am currently learning Dynare in Julia. I run the following code in Julia :

``````
var Capital, Output, Labour, Consumption, Efficiency, efficiency, ExpectedTerm;

varexo EfficiencyInnovation;

parameters beta, theta, tau, alpha, psi, delta, rho, effstar, sigma;

/*
** Calibration
*/

beta    =  0.990;
theta   =  0.357;
tau     =  30.000;
alpha   =  0.450;
psi     =  -9.000; // Elasticity of substitution is 1/(1-psi)
delta   =  0.020;
rho     =  0.950;
effstar =  1.000;
sigma   =  0.010;

model;

// Eq. n°1:
efficiency = rho*efficiency(-1) + sigma*EfficiencyInnovation;

// Eq. n°2:
Efficiency = effstar*exp(efficiency); //-.5*sigma*sigma/(1-rho*rho)

// Eq. n°3:
Output = Efficiency*(alpha*(Capital(-1)^psi)+(1-alpha)*(Labour^psi))^(1/psi);

// Eq. n°4:
Consumption + Capital - Output - (1-delta)*Capital(-1);

// Eq. n°5:
((1-theta)/theta)*(Consumption/(1-Labour)) - (1-alpha)*(Output/Labour)^(1-psi);

// Eq. n°6:
(((Consumption^theta)*((1-Labour)^(1-theta)))^(1-tau))/Consumption - ExpectedTerm(1);

// Eq. n°7:
ExpectedTerm = beta*((((Consumption^theta)*((1-Labour)^(1-theta)))^(1-tau))/Consumption)*(alpha*((Output/Capital(-1))^(1-psi))+1-delta);

end;

Efficiency_ss = effstar;
Output_per_unit_of_Capital= ((1/beta-1+delta)/alpha)^(1/(1-psi));
Consumption_per_unit_of_Capital=Output_per_unit_of_Capital-delta;
Labour_per_unit_of_Capital=(((Output_per_unit_of_Capital/Efficiency_ss)^psi-alpha)/(1-alpha))^(1/psi);
Output_per_unit_of_Labour=Output_per_unit_of_Capital/Labour_per_unit_of_Capital;
Consumption_per_unit_of_Labour=Consumption_per_unit_of_Capital/Labour_per_unit_of_Capital;

// Compute steady state share of capital.
ShareOfCapital=alpha/(alpha+(1-alpha)*Labour_per_unit_of_Capital^psi);

/// Compute steady state of the endogenous variables.
Labour_ss=1/(1+Consumption_per_unit_of_Labour/((1-alpha)*theta/(1-theta)*Output_per_unit_of_Labour^(1-psi)));
Consumption_ss = Consumption_per_unit_of_Labour*Labour_ss;
Capital_ss = Labour_ss/Labour_per_unit_of_Capital;
Output_ss = Output_per_unit_of_Capital*Capital_ss;
ExpectedTerm_ss = beta*((((Consumption_ss^theta)*((1-Labour_ss)^(1-theta)))^(1-tau))/Consumption_ss)*(alpha*((Output_ss/Capital_ss)^(1-psi))+1-delta);

initval;
efficiency = 0;
Efficiency = .95*effstar;
Labour = Labour_ss;
Consumption = 1.1*Consumption_ss;
Capital = .85*Capital_ss;
Output = Output_ss;
ExpectedTerm = ExpectedTerm_ss;
end;
``````

Julia gives the following error message :

LoadError: MethodError: no method matching LinearRationalExpectations.LinearRationalExpectationsResults(::Int64, ::Int64, ::Int64)

However, the code works well in Matlab. Do you have any suggestions ?
