Modelling Biased Human Trust Dynamics1

Within human trust related behaviour, according to the literature from the domains of Psychology and Social Sciences often non-rational behaviour can be observed. Current trust models that have been developed typically do not incorporate non-rational elements in the trust formation dynamics. In order to enable agents that interact with humans to have a good estimation of human trust, and take t...

P-recurrence in Topological Dynamics1

1. Definitions. The general reference for definitions is [3]. Throughout the paper (X, T, ir) will denote a transformation group for which X is a compact Hausdorff space. Whenever it is stated that X is a uniform space, it will be implicitly assumed that the (Hausdorff) topology of X is the one induced by the uniformity. It is further assumed that T is abelian. P and Q will be used to denote re...

Proximal Relations in Topological Dynamics1

Standing notations. Let (X, T, ir) be a transformation group with compact phase space. The proximal relation of (X, T, if) is denoted by P(X) and the syndetically proximal relation by L(X). The product transformation group induced by (X, P, 7r):;will be denoted by (XXX, T, p), which is defined by (x, y)pi = (xirt, yir1) for (x, y) QXXX and tQ T. For simplicity we shall write xt for X7r' and (xt...

Optimal Lending Contracts and Firm Dynamics1

We develop a general model of lending in the presence of endogenous borrowing constraints. Borrowing constraints arise because borrowers face limited liability and debt repayment cannot be perfectly enforced. In the model, the dynamics of debt are closely linked with the dynamics of borrowing constraints. In fact, borrowing constraints must satisfy a dynamic consistency requirement: The value o...

When did the human population size start increasing?

We analyze the frequency spectra of all available human nuclear sequence data sets by using a model of constant population size followed by exponential growth. Parameters of growth (more extreme than or) comparable to what has been suggested from mtDNA data can be rejected for 6 out of the 10 largest data sets. When the data are separated into African and non-African samples, a constant size no...
