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,...

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...

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...

In this thesis we consider two comparative statics questions of changes in risk. The first question concerns situations where an individual faces some risk and has no control over the uncertain environment. In these situations we ask what kind of changes in risk will cause the individual's...

Common sense is a dynamic concept and it is natural that our (statistical) common sense lags behind the development of statistical science. What is not so easy to understand is why common sense lags behind as much as it does. We conduct a survey among Japanese students and try to understand why...
