Aquest estudi examina l'ús d’applets interactius per millorar l’aprenentatge de matemàtiques aplicades a l’economia. Els applets faciliten la comprensió activa amb visualitzacions dinàmiques. El grup experimental va superar ...
In this paper, we explore the issue of manipulability in the setting of financial systems by considering two weak forms of immunity: merging-proofness and splitting-proofness. Not surprisingly, splitting-proofness conflicts ...
This paper studies committee design when a homogeneous population is uncertain about which alternative is correct, individuals can acquire costly information about the state of the world, and the decision must be taken via ...
We provide axiomatic characterizations of the constrained equal awards and constrainedequal losses rules by imposing immunity principles such as non-manipulability via merging(splitting) and strong non-manipulability via ...
We study claims problems in which agents may also have reference points. We show first that many classical rules satisfy an egalitarian property in this setting; namely, the differences between each agents’ payoff and the ...
This article presents the development of LOSARI, a novel R-based statistical software designed to facilitate students’ self-regulated learning (SRL) in statistics courses. LOSARI can be accessed online without installation ...
We study the local sensitivity of heating degree day (HDD) and cooling degree day (CDD) temper-ature futures and option prices with respect to perturbations in the deseasonalized temperature or inone of its derivatives up ...
This article presents a transparent and replicable framework to assess the net worth of public pension systems within the broader context of fiscal sustainability and public sector balance sheets. Using Spain as a case ...
We adopt the notion of the farsighted stable set to determine which matchings are stable when agents are farsighted in matching markets with couples. We show that a singleton matching is a farsighted stable set if and only ...
Requerimientos técnicos: Tener instalado el software R (cualquier versión) y cargar el área de trabajo.
We study the time-consistent investment and contribution policies in a defined benefit stochastic pension fund where the manager discounts the instantaneous utility over a finite planning horizon and the final function at ...
Using game theory, this study analyzed clients' decisions after receiving digital relational marketing campaigns via email for two types of products: apparel and electronics-music-video. The objectives were to analyze the ...
For purposes of ratemaking, time dependence and cross dependence have been treated as separate entities in the actuarial literature. Indeed, to date, little attention has been paid to the possibility of considering the two ...
Requeriments tècnics: Para poder ejecutar el aplicativo deben habilitarse las macros al abrir el archivo. - Sistema Operativo Windows XP, Vista o 7 (versiones de 32 bits y 64 bits). - Microsoft Excel 2007, 2010 o 2013 ...
This paper presents an analysis of multi-expert multi-criteria decision making (ME-MCDM) model based on the ordered weighted averaging (OWA) operators. Two methods of modeling the majority opinion are studied as to aggregate ...
In this paper, we study an advertising dynamic game in supply chain management under the assumption that the agents differ in their time preference rates. We study two coordination mechanisms: the cost sharing program, ...
An aging population and the economic crisis have placed pay-as-you-go pension systems in need of mechanisms to ensure their financial stability. In this article, we consider optimal indexing of pensions as an instrument ...
In this work tailor robust metrics are proposed to be used in the predictors’ space of distance-based predictive models. The first proposal is a robust version of Gower’s distance, which takes into account the correlation ...
We study a class of collusive equilibria in differential games with asymmetric players discounting the future at different rates. For such equilibria, at each moment, weights of players can depend on the state of the system. ...
We introduce semi-flexible majority rules for public good provision with private valuations. Such rules take the form of a two-stage, multiple-round voting mechanism where the output of the first stage is the default ...
