analysis: a mix
of market &
shadow prices
Efficiency Analysis is similar to Market Analysis, except that we use shadow prices when social and private values differ
Efficiency analysis
We want all costs to be quantified as the opportunity cost of the inputs, which is why we use shadow prices instead of market prices
Similarly, the benefits are the value of the outputs, at market prices if the market is efficient and shadow prices if there are market failures

Let's go through some of our cost and benefit categories & think about what prices they should be valued at!
Efficiency analysis: imports
Imported goods in US$: valued at c.i.f, meaning the price at the border

What about labour?
Efficiency analysis: labour
What about labour?
Remember: we're told all construction labour is unskilled
"There is considerable unemployment in the area and the shadow wage of unskilled labour recruited in the Bangkok area is assumed by the government to be 50% of the market wage."
