Does this mean happy days in Bogota

“This is a learning experiment! We are realizing that we can live without cars!” Mr. Peñalosa bellows as he cruises across the southbound lanes of Avenida 19, pausing on the wide, park-like median. A flock of young women rolls up the median’s bike path, shouting, “Mayor! Mayor!” though it has been six years since Mr. Peñalosa left office (consecutive terms are constitutionally banned in Bogota) and he has only just begun his campaign to regain the mayor’s seat.

Car Free Day is just one of the ways that Mr. Peñalosa helped to transform a city once infamous for narco-terrorism, pollution and chaos into a globally lauded model of livability and urban renewal. His ideas are being adopted in cities across the developing world. They are also being championed by planners and politicians in North America, where Mr. Peñalosa has reinvigorated the debate about public space once championed by Jane Jacobs.

His [Peñalosa] policies may resemble environmentalism, but they are no such thing. Rather, they were driven by his conversion to hedonics, an economic philosophy whose proponents focus on fostering not economic growth but human happiness.

Proponents of hedonics, or happiness economics, have been gaining influence. London School of Economics professor Richard Layard, who wrote the seminal Happiness: Lessons from a New Science, was an adviser to Tony Blair’s first Labour government. Prof. Layard asserts that, contrary to the guiding principle of a century of economists, income is a poor measure of happiness. Economic growth in England and the U.S. in the past half-century hasn’t measurably increased life satisfaction.
