Abstract

This paper analyzes the effect of a progressive taxation

scheme on the segregative properties of the endogenous

formation of jurisdictions. Households living in the

same place form a jurisdiction which aims to produce a

local public good and implement a redistribution policy

by granting every household a demogrant of an amount

determined by the jurisdiction. In every jurisdiction,

production of local public services and the demogrant

are financed with a local tax based upon the households

wealth. Local wealth tax rates and the level of the de-

mogrant are exogenously determined in every jurisdic-

tion. Households are free to leave their jurisdiction for

another jurisdiction that would provide them with their

highest utility. We found that the existence of a de-

mogrant seems to mitigate the segregative properties of

endogenous jurisdiction formation, because the condi-

tion identified by Gravel and Thoron to ensure segre-

gation of any stable jurisdiction structure remains

necessary, but is no longer sufficient.

1|INTRODUCTION

Local jurisdictions have a well‐known role: the production of public goods. However, more and

more, they choose to have a hand in wealth redistribution. Although, in most countries, local

taxation is proportional, which prevents the implementation of a redistributive taxation policy,

jurisdictions have other ways to implement a policy to reduce wealth inequality. They can, for

instance, provide a demogrant to households.

As highlighted by many economists, segregation by wealth seems to be an expanding

phenomenon. Within an urban area, one can observe jurisdictions with mainly poor
