I consider the interaction between an agent and a principal who is unable to commit not to renegotiate. The agent's type only affects the principal's utility. The principal has access to a public signal, correlated with the agent's type, which can be used to (imperfectly) verify the agent's...

In the present paper, we propose a new approach to investigate the logistic function, which is commonly used in mathematical models in economics and management. The approach is based on indicating in a given time series, having a logistic trend, some characteristic points corresponding to zeroes...

The aim of this paper is to present data to verify the process of mathematization in economic theory. For this we used two representative samples from three of the most in fluential academic journals in the years 1955-56-57 and the years 2015-16-17. Thus, a contingency table was drawn up,...

This article reveals a discontinuity in the mapping from a Lorenz curve to the associated cumulative distribution function. The problem is of a mathematical nature-based on an analysis of the transformation between the distribution function of a bound random variable and its Lorenz curve. It...
