Application of a self-learning methodology for the enhancement of the oral communication student outcome in International Business studies
2019
[EN] Effective oral communication is one of the most demanded student outcomes in the labour market, especially for degree students on International Business. Although this outcome is usually evaluated in several subjects along the curriculum, it is barely worked neither inside nor outside the classroom, mainly due to lack of time and to unavailability of proper learning methodologies. The PIMECOE project, an innovation and educational improvement project on this matter, has developed a self-learning methodology on the Effective Oral Communication student outcome, in which auto-diagnosis tests, selflearning tools and peer assessments are conveniently combined to enhance the proficiency leve…
Analysis of the main weaknesses of university students regarding the "effective oral communication" student outcome
2019
[EN] The "Effective oral communication" is one of the most demanded student outcomes in the workplace, since being a good communicator is essential in any field. Inefficient communication can lead to misinterpretations and erroneous conclusions. Therefore, it is a very important student outcome both in the university and in the workplace. The student or graduate must know how to communicate effectively, both orally and in writing, appropriately using the necessary resources and adapting to the characteristics of the situation and the audience. However, despite its importance, the disparity in the mastery level of the oral communication student outcome by students makes it difficult to work …
Telephone Consultation
2016
The article by Martina Albrecht and her co-authors (1) addresses an important aspect of patient-oriented medical decision making in Germany: to what extent does the advice dispensed by the freely accessible telephone consultation services correspond with the evidence? In other words: Can people who turn to these services understand and trust the information they are given? Only six of 293 consultations fulfilled the criteria defined by the authors—on the face of it, an alarming outcome.
Redistribution of tax resources: a cooperative game theory approach
2021
AbstractWe consider the problem of how to distribute public expenditure among the different regions of an economic entity after all taxes have been collected. Typical examples are: the regions that make up a country, the states of a federal country, or the countries of a confederation of countries. We model the problem as a cooperative game in coalitional form, called the tax game. This game estimates the fiscal resources collected in each region, or coalition of regions, by differentiating between what comes from economic activity within each region and what comes from trade with the other regions. This methodology provides a measure of the disagreement within a region, or coalitions of re…
The optimal degree of commitment in a negotiation with a deadline
2004
This note explores the consequences of a player's freedom of choice over his degree of commitment for the bargaining outcome. In particular, we modify the nonstationary structure of Fershtman and Seidmann (1993)'s bargaining by allowing one player to possess imperfect commitments where the degree of commitment is chosen prior to the negotiation stage. We show that a player optimally chooses an intermediate degree of irrevocability provided the costs of increasing the degree of commitment are small enough. In this case, not only an immediate agreement is reached but also the commitment is effective.
Welfare, Home Market Effects, and Horizontal Foreign Direct Investment
2005
We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing the equilibrium and the first-best, we show that both organizational and spatial inefficiencies may arise. In particular, when fixed costs are low enough the market outcome may well lead to overinvestment and, therefore, to too many multinationals operating from a social point of view. Furthermore, once multinationals are taken into account, the market outcome may well lead too little agglomeration.
Revisiting the Mathematical Difficulties in Patinkin Cartel Model and Joint Profit Maximization
2015
We discuss the mathematical difficulties encountered in Patinkin's classical cartel model. It may be impossible to derive Patinkin's cartel by finding the reciprocal marginal cost functions: it could be impossible for cartel members to compute a solution, unless certain assumptions are made to simplify the problem, such as quasi-linear marginal costs or constant marginal costs. The total cost function is incoherent with respect to the sum of members' total cost. The model cannot handle constant marginal costs but we remind that de Mesnard's (2009, 2011) model of cartel with exogenous market shares allow solving the problem. We conclude that the Patinkin model of cartel is not so self-eviden…
Strategic behavior and partial cost sharing
2003
Abstract The main objects here are games in which players mainly compete but nonetheless collaborate on some subsidiary activities. Play assumes a two-stage nature in that first-stage moves presume coordination of some subsequent tasks. Specifically, we consider instances where second-stage coordination amounts to partial cost sharing, anticipated and sustained as a core solution. Examples include regional Cournot oligopolies with joint transportation. We define and characterize equilibria, and inquire about their existence.
A Binary Particle Swarm Optimization Algorithm for a Double Auction Market
2007
In this paper, we shall show the design of a multi-unit double auction (MDA) market. It should be enough robust, flexible and sufficiently efficient in facilitating exchanges. In a MDA market, sellers and buyers submit respectively asks and bids. A trade is made if a buyers bid exceeds a sellers ask. A sellers ask may match several buyers bids and a buyers bid may satisfy several sellers asks. The trading rule of a market defines the organization, information exchange process, trading procedure and clearance rules of the market. The mechanism is announced before the opening of the market so that every agent knows how the market will operate in advance. These autonomous agents pursue their o…
Self-Enforcing International Environmental Agreements: Adaptation and Complementarity
2018
This paper studies the impact of adaptation on the stability of an international emission agreement. To address this issue we solve a three-stage coalition formation game where in the first stage countries decide whether or not to sign the agreement. Then, in the second stage, signatories (playing together) and non-signatories (playing individually) select their levels of emissions. Finally, in the third stage, each country decides on its level of adaptation non co-operatively. We solve this game for two models. For both, it is assumed that damages are linear with respect to emissions which guarantee that emissions are strategic complements in the second stage of the game. However, for the …
