Question

Hi, 

 

Could you help me solve this problem? 

 

The problem is a continuance to an ”efficient output ” based on a social planner’s problem, where it was compared to the output in the market equilibrium with monopolistic competition.

The problem:

Now consider the social planner’s problem in the context of labour supply and income taxation and compare the solution to it to a market equilibrium with potentially distortionary taxation. The rest of the problem is attacteh ad an image.

The problem of a representative household (representing aggregate labour supply) is to
choose consumption c and hours worked h to maximize
log(c) +log(1)
subject to
and
C = = (1 – t)wh
h+1= L,
where I denotes leisure, w wage rate, 0 < t < 1 income tax rate, and L > 0 fixed time en-
dowment.
=
Aggregate output is determined as Y Ah, where A > 0. The government budget constraint
is twh = G, where G> 0 denotes government consumption, and the aggregate resource
constraint is
Y = c + G.
In the market equilibrium, the labour market is competitive and hence w = A.
i) Derive hours worked (as a function of the parameters of the model) in the market equili-
brium where hours worked solve the problem of the representative household above and the
tax rate is set so that the government budget constraint is satisfied. You should focus only
on cases where G is small enough so that private consumption c is always strictly positive
and G in the market equilibrium can be financed with tax rate t < 1.
ii) Then formulate the problem of a social planner that takes G as given and maximizes
household welfare subject only to the aggregate resource constraint and the time constraint
h+ 1 = L and use it to derive socially optimal hours worked. Also compare the solution to
market equilibrium.
