About this Event

In this paper Professor Tsilly Dagan explains why designing a country’s tax policy with the elasticity of taxpayers’ choices of residency in mind, although a rational welfare-maximizing move by the state as a whole, and possibly even for its immobile as well as mobile constituents, is a policy that may not be justified under a liberal-egalitarian social contract.

She discusses two polar views of the social contract: one endorsing the state with the coercive power to promote the joint interests of its constituents. The other views the coercive power of the state as a way to fulfill the collective will of its constituents as a society of equals in order to promote who they are as people. If states’ coercive power is based on the latter, a policy that undercuts equal respect and concern might not be justified. The state thus faces a dilemma: taking into account the increased electivity of taxation (by some) could undermine the normative foundations of the power of the state to tax. Ignoring such increased electivity, on the other hand, may limit the potential of (some) individuals and the state as a whole to flourish.
