Question 1: Ordinary Least Squares and Instrumental Variables (40 Marks)
Consider the classical linear econometric model. We analyze some properties of the Ordinary Least
Squares (OLS) and Instrumental Variables (IV) estimators. We will rely on Monte Carlo simulation methods.
In terms of notation, the index i = 1, ..., I denotes the units of observation in our (simulated) cross-sectional
sample, and I is the sample size. As the initial seed number, use your date of birth (e.g., if you were born
on April the 13th, use the number 13 as the seed).
(a) Set the sample size to I = 10, 000. First consider the explanatory variable (xi). Generate it by
drawing I independent observations from the standard normal distribution. Now consider the dependent
variable (yi). For every data point, you are asked to generate it using the following model, setting the true
parameter values to β0 = 0, β1 = 1 and σ
2ε = 2:yi = β0 + β1xi + εi, εi ～ N(0, σ2ε)
where the errors εi are drawn from the normal distribution.
(a.1) Compute the OLS estimates β?OLS
0 and βOLS1. Comment. You can find the relevant formulas here:
https://en.wikipedia.org/wiki/Simple linear regression
(a.2) Now reset the seed to its original value, and set the sample size to I = 100. Create 100 different
datasets, generating the values for xi and yi using the same procedure as above. Use a for-loop and set the
seed to seed=seed+itr, where itr stands for the iteration number. On each sample, compute the 100 OLS
estimates βOLS
0 and βOLS
1 and plot them with two histograms. Comment.
(a.3) Now we move to analyze an IV estimator. Reset the seed to its original value and generate three
sets of I = 10, 000 independent error terms, denoting them as η1, η2 and η3. These shocks are drawn from
independent normal distributions N(0, σ2η = 2).
Consider the explanatory variable (xi), and generate it as xi = β2η1,i + η2,i, with β2 = 1. Now consider
an instrumental variable (zi), and generate it as zi = β3η2,i + η3,i, with β3 = 1.
To conclude with, generate the dependent variable (yi), using the following model and setting the true
parameter values to β0 = 0, β1 = 1:
yi = β0 + β1xi + η1,i
Compute both the OLS estimate βOLS
1 and the IV (2SLS) estimate βIV1. To get the latter, first apply
the OLS formula to the model:
xi = γ0 + γ1zi + νi.
Then, compute the predicted values xi = γ0 + γ1zi. Finally, apply the OLS formula to the model:
yi = β0 + β1xi + ui
Comment.
(a.4) Now reset the seed to its original value, and set the sample size to I = 100. Create 100 different
datasets, generating the values for xi
, zi and yi using the same procedure as in part (a.3). Use a for-loop
and set the seed to seed=seed+itr, where itr stands for the iteration number. On each sample, compute
the 100 OLS estimates β?OLS
0 and the 100 IV estimates β?IV
1
. Plot them with two histograms and comment.
(a.5) Redo parts (a.3) and (a.4) when β3 = 0.1. Redo parts (a.3) and (a.4) when β3 = 0. Comment.
Page 2 of 5Computational Economics ECON 457 - A01
(b) Now consider a multivariate case with two explanatory variables and two instruments.
Generate five sets of I = 10, 000 independent error terms, denoting them as η1, η2, η3, η4 and η5. These
shocks are drawn from independent normal distributions N(0, σ2
η = 2).
Consider the two explanatory variables (x1,i, x2,i). Generate the first one as x1,i = β3η1,i + η2,i, with
β3 = 1. Generate the second one as x2,i = β4η1,i + η3,i, with β4 = ?1.
Now consider two instrumental variables (z1,i, z2,i). Generate the first one as z1,i = β5η2,i + η4,i, with
β5 = 1. Generate the second one as z2,i = β6η3,i + η5,i, with β6 = 1.
To conclude with, generate the dependent variable (yi), using the following model and setting the true
parameter values to β0 = 0, β1 = 1, β2 = ?1:
yi = β0 + β1x1,i + β2x2,i + η1,i
(b.1) Get both the OLS estimates and the IV estimates. For this part, you must use the matrix formulation
of the model, and obtain the vectors β?OLS and β?IV with matrix operations on the matrices X, Z, and
the vector y. The columns of the matrix X consists of the constant, the variable x1, and the variable x2.
The columns of the matrix Z consists of the constant, the variable z1, and the variable z2.
Compute the OLS estimates βOLS0, βOLS
1 and βOLS as:βOLS = (X0X)
Compute the IV estimates βIV0, βIV
1 and βIV
2 as:βIV = (Z0X)1
Comment.
(b.2) Now reset the seed to its original value, and set the sample size to I = 100. Create 100 different
datasets, generating the values for x1, x2, z1, z2 and y using the same procedure as above. Use a for-loop and
set the seed to seed=seed+itr, where itr stands for the iteration number. On each sample, compute the
100 OLS estimates βOLS and the 100 IV estimates β?IV and plot them with histograms. Comment.
(b.3) Redo part (b.2) when β5 = 1 and β6 = 0.01, and when β5 = 0.01 and β6 = 1. Comment.
(b.4) Redo part (b.2) when β5 = 0 and β6 = 0. Comment.

Question 2: Optimal Taxation Policies (60 Marks)
In this question, we want to study the optimal mix of labor income taxes (Tl) and corporate taxes (Tf ),
in a situation where the tax revenues are used to finance total government expenditure (G). The government
runs a balanced budget, namely:
G = Tl + Tf
Total government expenditure consists of public investment (I), which is exogenous and constant, and
subsidies (S), which are variable and depend on the economy’s outcomes, with G = I + S. In order to
balance the budget, a proportional tax rate (τl) is imposed on workers’ income and a proportional tax rate
(τf ) is imposed on corporate income.
In the economy, there are L identical potential workers. The unemployed individuals, if any, do not
pay taxes and do not produce any output. The employed ones they all earn the same wage (w), and their
after-tax income is:
(1τl)w
Firms maximize their profits (π) and rely on one input, labor (l), to produce a homogeneous good (y). All
firms have access to the same technology, a decreasing return to scale production function (with parameter
0 < φ < 1), but they differ in their productivity, captured by the variable a:
y = alφ
Productivity is assumed to be log-normally distributed across firms, with probability density function
f(a) and parameters μa and σ. The price of the final good is normalized to 1. It follows
that total pre-tax revenues (R(a)), net of labor costs, are:
R(a) = alφ ? wl
The government subsidizes job creation, giving each firm a proportional subsidy (s) per employed worker.
Total profits for a firm (π(a)), inclusive of the government interventions (corporate taxes and labor subsidies),
are:
π(a) = (1 τf )R + sl = (1 τf )(alφ wl) + sl
(a) For this part of the question assume that φ = 0.6, τf = 0.4, τl = 0.2, s = 0.1, w = 1, μa = 0 andσ2
a = 2. Notice also that here the government does not run a balanced budget and L is to be interpreted as
a large number that is not binding.
Solve the problem of the firm and obtain the labor demand functions at the level of the individual firm
(l(a)). Calculate total output (Y ), which is defined as follows:
Explain how you implemented this computation.
Now compute total output using different parameter values. In one case they are:
φ = 0.7, τf = 0.4, τl = 0.2, s = 0.1, w = 1, μa = 0, σ2
a = 2.
In another case they are:
φ = 0.6, τf = 0.6, τl = 0.2, s = 0.1, w = 1, μa = 0, σ2
a = 2.
In a final case they are:
φ = 0.6, τf = 0.6, τl = 0.2, s = 0.1, w = 2, μa = 0, σ2
a = 2.
Page 4 of 5Computational Economics ECON 457 - A01
Report your results in a table and comment on your findings, stressing the economic channels at play.
(b) For this part of the question assume that φ = 0.6, τf = 0.4, s = 0.1, I = 10, w = 1, μa = 0 andat here L is to be interpreted as a large number that is not binding, namely L ≥ l
is total labor demand.
Find the labor income tax rate τl that allows the government to run a balanced budget. Explain how
you implemented this computation and which numerical methods you have used.
(c) From now on, assume that labor supply (ls) is flexible and represented by the following schedule:
ls = [10 (1τl)w]1ε
Assume that φ = 0.6, τf = 0.4, τl = 0.2, s = 0.1, I = 10, ε = 0.5, μa = 0 and σ2
a = 2. Notice also that
for this part of the question the government does not run a balanced budget, and L is to be interpreted as
a large number that is not binding, namely L ≥ l
s
.
Find the wage w that clears the labor market. Explain how you implemented this computation, report
your results and comment.
Hint: Use a guess and verify procedure. Guess the wage w0 and obtain the labor demand functions
at the level of the individual firm by solving their profit maximization problem. Compute the total labor
demand l
d
(w0) and the labor supply l
s
(w0). If they are different, update the guess on the wage and iterate
until convergence. For this problem, bisection would work well.
(d) For this part of the question retain the same labor supply function used in part (c).
Assume that φ = 0.6, s = 0.1, I = 10, ε = 0.5, μa = 0 and σ
2
a = 2. Notice that here L is to be interpreted
as a large number that is not binding, namely L ≥ l
s
. The government runs a balanced budget and the
labor market has to be in equilibrium.
For a constant job creation (proportional) subsidy s = 0.1, find the combination of corporate tax rate
(τf ) and labor income tax rate (τl) that maximizes aggregate output. Explain how you implemented this
computation, report your results and comment.
(e) Now the job creation (proportional) subsidy s is no longer fixed. Find the combination of corporate
tax rate (τf ), labor income tax rate (τl), and labor subsidy (s) that maximizes aggregate output. Explain
how you implemented this computation, report your results and comment.
