1. Africa at a Turning Point?

2. Banking on Urbanization For decades commodity prices have influenced Africa’s growth performance. If commodity prices continue to decline, is there another way forward? Story of next decade: rising urban population & land prices.

3. Rising demand for urban land Nairobi (4km from CBD): 2004Nairobi (4km from CBD): 2013

4. Land appreciation is a rent analogous to natural resource rents.

Local governments can take advantage of these price increases by taxing the appreciation in urban land values.

5. Land appreciation is not due to any activity of the owner so: Land taxes are not distortionary. Land taxes are fair.

6. Building a Successful City Requires Investment Infrastructure Housing Commercial/Industrial

7. When urban investment is done well, it generates a triple miracle of productivity.

8. Triple Miracle of Productivity Clusters of Firms→ Enable scale & specialization Density of settlement→ Concentrates demand Workers proximity to jobs→ Matches abilities to opportunities

9. These investment decisions are made by different people. And need to be coordinated.

10. Infrastructure is the coordinating mechanism.

11. Urban planning is not sufficient to coordinate investments. Early infrastructure investments help to make plans credible.

12. Early infrastructure is also cheaper. Costly to retrofit it once people have settled.

13. Sequencing is Important Getting it Right Infrastructure→ housing Getting it Wrong Settlement→ little infrastructure

14. Transforming Africa’s Cities into Global Cities

15. Most African Cities are Artisanal Cities A high percentage of urban workers are employed in the informal sector and produce non-tradable goods & services. Firm producing non-tradable goods tend to be small with low productivity.

16. Firms in artisanal cities have higher costs of doing business than firms in global cities. Why? Because they have higher transport costs—due to low quality infrastructure. Because they are small—not reaping the benefits of economies of scale.

17. The way forward: Designing livable density: Clusters of firms. Clusters of people. Proximity of workers to firms.
