We present a geometric model of social choice among bundles of interdependent elements, that we will call objects. We show that the outcome of the social choice process is highly dependent on the way these bundles are formed. By bundling and unbundling the same set of constituent elements an...

In the article investigational method of diagnostics of efficiency of controlling of business processes, resulting in its implementation it is possible to identify deficiencies controlling systems. The essence of this method is compared to the controlling systems with a reference value.

Web servers worldwide generate a vast amount of information on web users’ browsing activities. Several researchers have studied these so-called clickstream or web access log data to better understand and characterize web users. The goal of this application is to analyze user behaviour by...

In this paper, the authors develop a new estimation method that is suitable for censored models with two high-dimensional fixed effects and that is based on a sequence of least squares regressions, yielding significant savings in computing time and hence making it applicable to frameworks in...

We propose and axiomatically analyze a class of rational solutions to simple allocation problems where a policy-maker allocates an endowment <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$E$$</EquationSource> </InlineEquation> among <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$$n$$</EquationSource> </InlineEquation> agents described by a characteristic vector c. We propose a class of recursive rules which mimic a decision process where the...</equationsource></inlineequation></equationsource></inlineequation>
