Article
In the last two decades, the hedge fund sector has experienced a spectacular growth, up to the point that it is currently estimated to move more than 50% of the daily volume of stock markets. In contrast to other financial institutions, hedge funds are subject to less restrictive regulations which, in particular, allow them to sell short. As they e...

The financial system is inherently procyclical, as it amplifies the course of economic cycles, and precisely one of the factors that has been suggested to exacerbate this procyclicality is the Basel regulation on capital requirements. After the recent credit crisis, international regulators have turned their eyes to countercyclical regulation as a...
Experiment Findings

This is the final report on the VETNET network project that was carried out in the ECER 2018 conference in Bolzano/Bozen. The project was supported by the European Educational Research Association (EERA). The aim of the project was to pilot test the use of ePosters powered by the Learning Toolbox (LTB) as means to present educational research in a...
Conference Paper
Full-text available
This paper presents a reflective case study of the introduction of Learning Toolbox as an ePoster solution for conferences. The Learning Toolbox ePoster platform is designed to overcome practical knowledge sharing and communication problems encountered in both the traditional paper poster and standard, screen-based ePoster approaches. Additionally...

The use of agent-based models (ABMs) has increased in the last years to simulate social systems and, in particular, financial markets. ABMs of financial markets are usually validated by checking the ability of the model to reproduce a set of empirical stylised facts. However, other common-sense evidence is available which is often not taken into ac...

Background: How can mobile technology support practice-based learning of nursing students in complex health care settings and create a bridge to their formal education? We report on the first stage of an exploratory study at Universitat Gimbernat (Barcelona) involving 10 volunteer students, their tutor, and the department's placement coordinator. S...
Article
Financial institutions around the world use value-at-risk (VaR) models to manage their market risk and calculate their capital requirements under Basel Accords. VaR models, as any other risk management system, are meant to keep financial institutions out of trouble by, among other things, guiding investment decisions within established risk limits...

The overall objective of WP6 is to co-ordinate and synchronize all technology development tasks across the project, as well as providing a base architecture to support this. In Y3, we have addressed this overall goal in the following ways: In T6.2 (Distributed process and platform for Layers software engineering and integration) we have started to...

Purpose: The development of a game based approach to improving the decision-making capabilities of financial traders through attention to improving the regulation of emotions during trading. Design/methodology/approach: The project used a design-based research approach to integrate the contributions of a highly inter-disciplinary team. The approac...
Conference Paper
Full-text available
We describe an approach to reducing systematic bias in financial decision-making. We explicitly reject an approach based on the transmission of propositional knowledge. Rather we develop a learning design which is founded in recent research on the role of emotions and their regulation in financial decision-making. We describe a pedagogic approach w...

In the general population, alarming levels exist of financial illiteracy. Many people do not understand financial products very well, and this may have severe consequences for the finances of individual households. Yet, in addition to financial literacy, it may also be that some individuals are more skilled to make financial decisions than others....
Conference Paper

Agent-based models have a great potential for the simulation of historical episodes that has to date barely been explored. We focus in particular on the simulation of historical episodes in financial markets, and present here an empirically grounded model of the 1998 turmoil that caused the collapse of the LTCM hedge fund. This model allows us to e...

Questions about methodology and model design are subject to constant debate in the emerging field of agent-based modelling and simulation. This article intends to make progress on some of the more foundational aspects affecting method and design. Our primary focus is on a much neglected area of agent-based modelling, namely that of large-scale, spa...

This article is not about models, but about designing models. Questions about methodology and model design are subject to constant debate in the emerging field of agent‐based modelling and simulation, especially where they pertain to modelling of financial markets. This article intends to make some progress on some of the more practical facets of k...
Article
Full-text available
The trading and investment decision processes in financial markets become ever more dependent on the use of valuation and risk models. In the case of risk management for instance, modelling practice has become quite homogeneous and the question arises as to the effect this has on the price formation process. Furthermore, sophisticated investors who...

There is widespread speculation but little hard evidence that the ever increasing use of financial models establishes a ready channel for contagion and that this can, under adverse circumstances, pose an authentic threat to the stability of financial markets. This article presents a simple simulation exercise that lends support to MacKenzie's thesi...

En los últimos años ha habido un gran número de crisis financieras con graves efectos en la economía de los países afectados. Para evitar o minimizar estos efectos negativos es necesario entender qué factores pueden desencadenar una crisis financiera. Sin embargo, la literatura sólo ofrece explicaciones de tipo cualitativo o modelos analíticos muy...
Conference Paper
Full-text available
Recently, some authors have warned of the increasingly widespread use of risk management techniques by financial institutions, arguing that this can cause the market to become more unstable. To analyse these claims, we present a model based on evolutionary game theory of a financial market, where part of the investors use the VaR technique to manag...
Conference Paper
Full-text available
This paper sets out to study the impact that market risk limits have on the price dynamics in securities markets. We start out from a standard model in which trading patterns are determined for utility-maximising investors in non-clearing markets with a particularly simple price formation mechanism. To make trading conditions more realistic, we add...

Els mercats financers són un exemple paradigmàtic de sistemes complexos adaptatius. Els paradigmes tradicionals de modelització no permeten reflexar aquesta realitat i hem de recórrer a noves eines. Presentem la simulació basada en sistemes multi-agents com el paradigma idoni per a analitzar els mercats financers en tota la seva complexitat. És un...

Project
Learning Layers was a 4 year (November 2012 – October 2016), large-scale research project co-funded by the European Commission’s 7th Framework Programme as part of the Technology Enhanced Learning call. The focus of the Learning Layers research was on understanding learning at the workplace and developing a set of modular and flexible technologies for supporting this workplace learning in networks of Small and Medium Enterprises (SMEs). The research took place in two sectors: health care in the UK and building and construction in Germany. The health care context focused on informal learning in primary care (specifically GP practices) and working closely with local GP practices, Clinical Commissioning Groups and other healthcare networks. The project explored how learning technology could support healthcare professionals’ informal learning and improve practice. It involved: 1. Building an understanding of the current learning practices in the GP practices. 2. Supporting the co-design of the technology tools 3. Piloting and evaluation of these tools in healthcare teams and networks. The project officially ended in December 2016 and our results website can be found at http://results.learning-layers.eu. However, some of collaborations and work is continuing and further updates and publications will be posted both here and on the results website.
