Rader's utility representation theorem guarantees the existence of an upper semicontinuous utility function for any upper semicontinuous total preorder on a second countable topological space. In this paper we present a generalization of Rader's theorem to not necessarily total preorders that...

. A wide body of literature on economic theory is devoted to the analysis of industrial goods markets with the possibility of advertising influence on demand. However, these models do not view media as industry entities with their own strategic goals and objectives. On the other hand, the main...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

In this article, an approach to the ecological footprint becomes from a microeconomic perspective, speci¯cally from the consumer traditional theory. It is revealed how the consumption of goods and services redound in the consumption of natural resources and provoke a decrease in the wellbeing...

This article studies an inter-temporal optimization problem using a criterion which is a combination between Ramsey and Rawls criteria. A detailed description of the saving behaviour through time is provided. The optimization problem under $\alpha-$\emph{maximin} criterion is also considered...

This paper examines the conditions for the existence of a maximal element of a relation on every nonempty compact subset of its ground set. A preliminary analysis establishes some connections between the maximals of a relation and those of its right trace. Via this analysis, various results of...

Consider an experiment in which subjects are asked to choose between pairs consisting of a monetary payment and a time-delay at which the payment is delivered. Given a finite set of observations, under what conditions the choices of an individual agent can be rationalised by a discounted utility...

The Szpilrajn "constructive type" theorem on extending binary relations, or its generalizations by Dushnik and Miller [10], is one of the best known theorems in social sciences and mathematical economics. Arrow [1], Fishburn [11], Suzumura [22], Donaldson and Weymark [8] and others utilize...
