Abstract
Brain modularity is a key concept in neuroscience. It challenges mon view of
the single coherent self adopted in many disciplines, including economics. Multi-process
theories of decision-making rely on the existence of several brain systems interacting with
each other to revisit standard paradigms of choice, propose choices that fit the behavioral
data better, and offer testable predictions. In this paper, we present a selective review of
our recent research in this area. We focus on constrained optimization models rather than
putational models extensively used in neuroscience.
Keywords: neuroeconomic theory, decision-making, dual-process, constrained optimiza-
tion.

1 Introduction
Brain modularity and neuroeconomic theory
The premise of Neuroeconomic Theory is the existence of multiple interacting brain sys-
tems. The relationship between brain systems is intricate. Typically, each system performs
different functions and each function needs the intervention of several systems. Neurosci-
entists refer to it as brain modularity. Taking a decision, solving a problem or performing
a motor task requires the coordination of different functions and therefore the involvement
of different systems. Depending on the nature of the function and the degree of the overlap
between systems, they will produce a response that is ‘as if’ they were cooperating with
each other or ‘as if’ they peting with each other.
The main consequence of such a construct is that an individual is best understood as
anization of systems. When a choice must be made, systems performing functions
related to that deci
