Agenda
• Entrepreneurship -> growth (?)
• Experimentation
• Externalities matter
• Entrepreneurial clusters in 2 minutes
• Evidence on traits of places
• Effective policy?

Experimentation’s Forms
• “Entrepreneurship as experimentation”
– Darwinian view of markets
– Sneaking away from Google

Experimentation’s Forms
• “Entrepreneurship as experimentation”
– Darwinian view of markets
– Sneaking away from Google
• Experimental notions
– Knightian uncertainty vs. risk
– You don’t get to test everything!
– Real options: expand the set of possible tests
– VC economics and contractual structures

Experimentation’s Frictions
• Costs of running experiments
– Financial barriers, lean start-up, etc.
– Non-financial costs like stigma of failure
• Organizational frictions
– “Throwing good money after bad”
– Impartial decisions and length of commitments
• Continuation and financing risk
– Stability of future financing availability
– Markets for ideas
![Page 13: Clusters of Entrepreneurship and Innovation, William Kerr](https://reader033.fdocuments.net/reader033/viewer/2022060117/55852a28d8b42a89488b45a6/html5/thumbnails/13.jpg)
Experimentation’s Consequences
• Some good news for policy makers
– Entry barriers and financing competition
– Bankruptcy law and rigid labor regulations
– {Not yet to justifying active policy!}
• Some worries for policy makers
– Cowan avoided the garage…
– The messy nature of “democratized” entry
– Commitment can be hard but essential

Active Policy Rationale
• Externalities
– Build local tax base
– Real externalities over firms
• Redistribution
– Fighting concentrated poverty (w/ focus on place)
• Credit constraints
– Credit market imperfections that limit start-ups

Clusters Abound

Issues on Clusters

Uneven Entrepreneurship
What do entrepreneurial places possess?
• Education + age structure + “supply”
– Physical infrastructure likely important too
• Strong link to industrial structure of city
• Role for high-skilled immigrants in US
• Appears that local spillovers are quite confined by distance, demographics, and similar…
• Networks matter a lot for the shape of clusters

Policy Types
• Increase “local supply”
• Direct subsidies and assistance
• Lowering the costs of starting/failing
• Regional cluster initiatives
• Local innovation clusters
• Don’t kill dynamics!

Wrapping Up
• Policy roles for entrepreneurship
– Nuanced economic theory, unknown parameters
– Accumulating empirical perspective
• Policy advice is very early-stage
– Don’t forget the basics! Clear role…
– For the rest, we need lots of experiments
– Proper design and evaluation critical
