Great definition of rent-seeking from Steve Blank in this post on Tesla. Stamping out rent seeking behavior has to be a key part of the liberal political program at the state and local level. I’d add food trucks and infill housing to the list of activities that threaten economic rents:
Rent seekers are individuals or organizations that have succeeded with existing business models and look to the government and regulators as their first line of defense against innovative competition. They use government regulation and lawsuits to keep out new entrants with more innovative business models. They use every argument from public safety to lack of quality or loss of jobs to lobby against the new entrants. Rent seekers spend money to increase their share of an existing market instead of creating new products or markets. The key idea is that rent seeking behavior creates nothing of value.
These barriers to new innovative entrants are called economic rent. Examples of economic rent include state automobile franchise laws, taxi medallion laws, limits on charter schools, auto, steel or sugar tariffs, patent trolls, bribery of government officials, corruption and regulatory capture. They’re all part of the same pattern – they add no value to the economy and prevent innovation from reaching the consumer.
