Questions
- How do we measure growth? How do we know what's growing?
- How is GDP calculated?
- What choices/judgment calls are made in the calculation?
- What's up with all these price indices/PPP formulas/aggregation methods?
- Basket construction
- Validation
- Going out and measuring things (surveys? taxation? some old dutch guy at a port kept import records?)
- Can we trust these GDP calculations?
- What choices/judgment calls are made in the calculation?
- How is GDP calculated?
