Teori, praktik, humor 4

Samma teori igen:

Incentives matter more than intentions.

Praktik - från New Zealand Herald:

Auckland's leafy suburbs constitute a sprawling world-class botanical garden and unique urban forest. The climate of Auckland is a convergence of tropical and temperate elements that allow a wide range of trees to grow together in a way rarely, if ever, encountered elsewhere.
/.../
Regardless of its noble intent, the introduction of laws to control the rights of landowners and the gardening public was fundamentally flawed, to such an extent that it all but killed overnight the market for large shady trees in the nursery trade. Once landowners and gardeners lost the freedom to manage their trees, people ceased planting them. It is now nearly two decades since the demand for large shade-producing trees was destroyed by regulation, with disastrous effect on the on-going development of the city's urban tree asset.

Humor - Milton Friedman:

If you put the federal government in charge of the Sahara Desert, in 5 years there'd be a shortage of sand.

Det bör noteras att jag gärna sett Friedmans kommentar en smula omformulerad, då ökenutbredning delvis är en allmänningens tragedi och alltså precis vad staten åstadkommer, men i sammanhanget får den duga.
