Policy Consequences: No Taxation of Intermediate Goods<br />

Consider two industries, with labor as the primary input<br />

Intermediate good A, final good B<br />

Industry A:<br />

Uses labor l A to produce good A<br />

One for one technology<br />

Industry B:<br />

Uses good A and labor l B to produce good B x B = F (l B , x A )<br />

Constant returns to scale<br />

With wage rate w, the producer price of good A is p A = w<br />

Suppose that good A is taxed at rate τ<br />

Then the cost for firm B of good A is w + τ<br />
