For a neural network with sign-constrained weights weights three types of attractor can affect the dynamics: retrieval, spurious and uniform attractors. The uniform attractors can dominate the dynamics if there is a substancial weight-sign bias. We will show that it is possible to define...

This paper addresses the question of how to adequately model empirical variation in willingness to pay (WTP) for a public good and demonstrates the importance of appropriate modelling of heterogeneity for policy and decision making on public good provision. Even if on average voters are to gain...
