The paper discusses the impact of the use of Facebook as a supporting learning platform for a course in Mathematics at the undergraduate level. After the examination of some critical issues of Facebook in a learning framework, we analyze data on the usage the page (total reach and number of...

Agent-based models of market dynamics must strike a compromise between the structural assumptions that represent the trading mechanism and the behavioural assumptions that describe the rules by which traders make their decisions. We present a structurally detailed model of an order-driven stock...

We develop a model where heterogeneous agents maximize their individual utility based on (after tax) income and on the level of public expenditure (as in Cowell, Gordon, 1988). Agents are different in risk aversion and in the relative preference for public expenditure with respect to personal...

Although mutual fund performance has been dissected from almost every angle, very little attention has been paid to the connection between the actual active decisions made by management and the subsequent performance outcomes. In this paper we use information on institutional mutual funds to...

We model a continuous double auction with heterogenous agents and compute approximate optimal trading strategies using evolution strategies. Agents privately know their values and costs and have a limited time to transact. We focus on equilibrium strategies that are developed taking into account...

We numerically determine the equilibrium trading strategies in a Continuous Double Auction (CDA). We consider heterogeneous and liquidity motivated agents, with private values and costs, that trade sequentially in random order under time constraints and are not aware of the type of the other...

Understanding what motivates and fosters collective actions has major implications in the regulation and design of public policies, in the governance and management of organizations and has long attracted the interests of scholars and practitioners in economics and business. If trust and...

Diversification has its obvious benefits but its pursuit can involve a trade-off between risk-controls and returns. We investigate this trade-off by examining the relative performance of diversified versus concentrated portfolios both formed on the basis of the same stock preferences. Using US...

One of several important strategic decisions that have to be made by an active funds management organization is how aggressively it implements its investment process. In this paper we model this decision on the assumption that the organization’s objective is to maximise the present value of...

A trader's execution strategy has a large effect on his profits. Identifying an optimal strategy, however, is often frustrated by the complexity of market microstructure's. We analyse an order book based continuous double auction market under two different models of trader's behaviour. In the...
