No, they don't. There is no influence on the prices of manufactured goods.
I think that's wrong.
A few minutes ago I've made a test in a new game. I set one brickyard and waited until it was full of workers. With timber at a price of 47, the bricks had a production-price of 78, with timber at 88 the price of the bricks was 99.
That' completely logical:
( 385 + 3.5 * 47 ) / 7 = 78,5
( 385 + 3.5 * 88 ) / 7 = 99
385 = wage + taxes
3.5 = used timber
47, 88 = price of timber
7 = produced bricks
