Many empirical and behavioral studies identify a decreasing slope in the term structure of subjective discount rates. Using an experimental methodology based on “free-time” relative comparisons, this paper aims to identify in individual behaviors whether agents see their psychological value...

ELECTRE TRI is a method designed to sort alternatives evaluated on several criteria into ordered categories. The original method uses limiting profiles. A recently introduced variant uses central profiles. We study the relations between these two variants. We do so by investigating if an ordered...

Strategy is made of moves, counter-moves, adjustments, actions and reactions. It is founded on an ever-changing external and internal context where numerous actors continuously modify the rules of the game. In these contexts, managers can’t rely on effective planned processes. They have to...

Many empirical and behavioral studies underline the idea of a non-flat term structure of subjective interest rates with a decreasing slope. Using an empirical test, this paper aims at identifying in individual behaviors whether agents see their psychological value of time decreasing or not. We...

Hypothetical bias is a long-standing issue in stated preference and contingent valuation studies—people tend to overstate their preferences when they do not experience the real monetary consequences of their decision. This view, however, has been challenged by recent evidence based on the...

This paper aims at providing a brief overview of the experimental method’s principles to researchers who face for the first time the use an experimental design. The purpose is also to guide them to a better understanding of the basic notions of control and threats to validities. Thus, they...

Prevention has been identified as an effective strategy to lead healthy, active and independent lives in old age. Developing effective prevention programs requires understanding the influence of both individual and health system level factors on utilisation of specific services. This study...
