This is my master code:

clear all;

%% Preamble

Parameters;

taux= 0.5; % robot tax

pir = pi_pred(2,:); %% fraction of routine workers

pin = pi_pred(1,:); %% fraction of non-routine

u=@(c) log(c); %Utility of consumption

up=@(c) 1./c; %Mg Utility of c

psi = @(l) zeta*l.^(1+nu)/(1+nu); %Labor disutility

psip = @(l) zeta*l.^nu; %Mg Utility Labor

util=@(c,l) u(c)-psi(l);

welf = @(un,ur,G,pn,pr) omegan*pn.*un+omegar*pr.*ur+chi*u(G);

%% Solve each model

g = gc./(1+gc);

fprintf('Solving Status Quo \n')

for t = 1 : T+1

lr_sq(t)=fzero(@(l) psip(l)*l-(1-gamma_sq),0.3);

ln_sq(t)=fzero(@(l) psip(l)*l-(1-gamma_sq),0.3);

end

taux_sq = 0.1*ones(1,T+1);

m_sq=1-(((1+taux)*phi)/(A*(1-alpha))).^(1/alpha).*(pir.*lr_sq./(pin.*ln_sq));

% wr_sq=(0.1+1)*phi;

wr_sq=(1+taux)*phi; %% routine wages with taux

wn_sq=A^(1/alpha)*alpha*(1-alpha)^((1-alpha)/alpha)./((1+taux)*phi).^((1-alpha)/alpha); %% non-routine wages with taux

G_sq=g.*(pir.*wr_sq.*lr_sq+pin.*wn_sq.*ln_sq);

This is my parameter code:

%% Data for occupations

load('../Data/Occupations Data/occ_data.mat','pi','year')

% The first hypothesis assumes shares will stay constant forever

pi_fix(end:T+1) = pi(1,end);

pi_fix(2,:) = 1 - pi_fix(1,:);

% Can also do shares evolving exogenously over time

y = log(1-pi(1,:));

x = [ones(1,size(pi,2)); 0:1:size(pi,2)-1];

bet = (x*x')^(-1)*(x*y');

pi_pred(1,1:T+1) = 1 - exp(bet(1)+bet(2)*(0:1:T));

% pi_pred(1,1:size(pi,2)-index+1) = pi(1,:);

pi_pred(2,:) = 1 - pi_pred(1,:);

clear year pi y x bet;

gamma = par.gamma; % 0.1845

gamma = 0.1845;

%% Preferences

zeta = par.zeta;

% zeta = 15

chi = par.chi;

%% Production

A = par.A;

phi = par.phitilde*exp(-par.gphi/10*(0:1:T));

alpha = par.alpha;

%% Get data for government

gc = target.gc;

%% Planner Pareto weights

omegar = 1;

omegan = 1;

%Time path for phi

I am guessinmg that it could be:

lambda_sq=(pir.*wr_sq.*lr_sq + pin.*wn_sq.*ln_sq) - g(pin.*wn_sq.*ln_sq.*(taux+alpha./alpha.*(1+taux)) + (pir.*wr_sq.*lr_sq./(1+taux))) ./ (pir.*(wr_sq.*lr_sq).^(1-gamma_sq) + pin.*(wn_sq.*ln_sq).^(1-gamma_sq));%% Goverment budget constraint with taux

↑ ← HERE

and there should be an element-wise multiplication operator: ... g.*( ... there.
