One of the ways that cities determine where they should spend money and invest is through something known as Participatory Budgeting. The birthplace of this approach is generally thought to be Porto Alegre in Brazil, which first adopted it in 1989. Since then, it has become a mainstream practice and spread to cities all around the world, including New York and Paris, both of which operate ambitious programs.

In the case of Paris, they have committed 5% of their capital budget to be spent in this way. The way it generally works is simple: citizens get to propose ideas and then vote on which urban projects they think should be funded. Last year, Paris saw 2,079 ideas proposed, 261 projects put to a vote, 162,395 votes, and 104 projects selected. And since the program launched in 2014, over €768 million has been allocated.

Some of these projects are very local and specific, such as "build a sports facility on this street," while others are city-wide, like "make things cleaner, be better at sorting waste and recycling, and reduce noise."

While there's lots of debate about the effectiveness of Participatory Budgeting, it does offer a number of benefits. Studies have shown that it can improve public trust in government institutions by making them more accountable. It can also help to educate residents on what things actually cost, making trade-offs more understandable. But most importantly, it can help to better allocate funds.

After all, who better to decide what a neighborhood needs than the locals who live there every day? Just don't ask about building new housing.
