这个问题总是出现。我在运行完整的模型（test1.mod）就会出现Residuals of the static equations:

Equation number 1 : 0 : w
Equation number 2 : 0 : c
Equation number 3 : 0 : 3
Equation number 4 : 0 : y
Equation number 5 : 0 : 5
Equation number 6 : 0 : pi_h
Equation number 7 : 0 : mc
Equation number 8 : 0 : 8
Equation number 9 : 0 : 9
Equation number 10 : 0 : k
Equation number 11 : 0 : d
Equation number 12 : 0 : r
Equation number 13 : 0 : 13
Equation number 14 : 0 : 14
Equation number 15 : 0 : po
Equation number 16 : 0 : pi
Equation number 17 : 0 : 17
Equation number 18 : 0 : c_s
Equation number 19 : 0 : w_s
Equation number 20 : 0 : 20
Equation number 21 : 0 : k_s
Equation number 22 : 0 : r_s
Equation number 23 : 0 : 23
Equation number 24 : 0 : i_s
Equation number 25 : 0 : a_s
Equation number 26 : 0 : mc_s
Equation number 27 : 0 : pi_s
Equation number 28 : 0 : a
Equation number 29 : 0 : 29
Equation number 30 : 0 : i


MODEL_DIAGNOSTICS:  The Jacobian of the static model is singular
MODEL_DIAGNOSTICS:  there is 1 colinear relationships between the variables and the equations
Colinear variables:
s
c_s
y_s
w_s
r_s
k_s
n_s
I_s
Colinear equations
     5     7    11    12    14    15

MODEL_DIAGNOSTICS:  The presence of a singularity problem typically indicates that there is one
MODEL_DIAGNOSTICS:  redundant equation entered in the model block, while another non-redundant equation
MODEL_DIAGNOSTICS:  is missing. The problem often derives from Walras Law.
错误使用 print_info (line 32)
Blanchard & Kahn conditions are not satisfied: indeterminacy.

出错 stoch_simul (line 107)
    print_info(info, options_.noprint, options_);

出错 test1.driver (line 443)
[info, oo_, options_, M_] = stoch_simul(M_, options_, oo_, var_list_);

出错 dynare (line 293)
evalin('base',[fname '.driver']) ;


所以我选择先修改，缩减模型（oil_smallopen.mod）
然而MODEL_DIAGNOSTICS是检测不出问题了 但依旧
错误使用 print_info (line 32)
Blanchard & Kahn conditions are not satisfied: indeterminacy。

两个文件在压缩包里。
求助！！！

您的模型不满足布兰查德条件，意即前向变量的个数要和不小于1的特征值的个数相等。造成这个问题的原因很复杂，原因是泰勒规则中通胀前面的系数接近于1或小于1，或是因为均衡条件输入有误，比如时间下标的错误，或是变量的初始值不恰当等。
