This paper investigates the impact of the quality of online corporate reporting (OCR) by UK listed firms on analyst behavior. Using a proposed new OCR index, we find that higher quality of OCR is related to increased analyst following. Additionally, we find that the main OCR component that...

Recent evidence from large-scale field experiments has shown that employers use job candidates' unemployment duration as a sorting criterion. In the present study, we investigate the mechanisms underlying this pattern. To this end, we conduct a lab experiment in which participants make hiring...

We develop a simple agent-based financial market model in which speculators' market entry decisions are subject to herding behavior and market risk. Moreover, speculators' orders depend on price trends, market misalignments and fundamental news. Using a mix of analytical and numerical tools, we...

An empirically founded and widely established driving force in opinion dynamics is homophily i.e. the tendency of "birds of a feather" to "flock together". The closer our opinions are the more likely it is that we will interact and converge. Models using these assumptions are called bounded...

Der Einführungszeitpunkt der Abgeltungsteuer zum 1.1.2009 war schon lange in der Öffentlichkeit bekannt. Der Kapitalmarkttheorie folgend wäre bei vollständiger Verarbeitung der bekannten Informationen zu erwarten gewesen, dass die Marktteilnehmer die mit der Abgeltungsteuer verbundene...

The paper investigates social-learning when the information structure is not commonly known. Individuals repeatedly interact in social-learning settings with distinct information structures. In each round of interaction, they use their experience gained in past rounds to draw inferences from...

We report two information cascade game experiments that directly test the impact of altruism on observational learning. Participants interact in two parallel sequences, the observed and the unobserved sequence. Only the actions of the observed entail informational benefits to subsequent...

In the context of a two-state, two-trader financial market herd model introduced by Avery and Zemsky (1998) we investigate how informational ambiguity in conjunction with waves of optimism and pessimism affect investor behavior, social learning and price dynamics. Without ambiguity, neither...

We present a novel approach towards the financial Ising model. Most studies utilize the model to find settings which generate returns closely mimicking the financial stylized fact such as fat tails, volatility clustering and persistence, and others. We tackle the model utility from the other...

In this paper, we introduce two classes of indices which can be used to measure the market perception concerning the degree of dependency that exists between a set of random variables, representing different stock prices at a fixed future date. The construction of these measures is based on the...

We study reputational herding in financial markets in a laboratory experiment. In the spirit of Dasgupta and Prat (2008), career concerns are introduced in a sequential asset market, where wages for investors are set by subjects in the role of employers. Employers can observe investment...

We take the model of Alfarano et al. (Journal of Economic Dynamics & Control 32, 2008, 101-136) as a prototype agent-based model that allows reproducing the main stylized facts of financial returns. The model does so by combining fundamental news driven by Brownian motion with a minimalistic...

Studies find that in time of crisis such as natural disasters, in most cases, people in crowds are capable to remain calm and to help each other. Referred as 'collective resilience', this capability can increase a society's capacity to withstand crises and disasters. Therefore, for both academia...

It is still an open question when groups perform better than individuals in intellective tasks. We report that in an Acquiring a Company game, what prevailed when there was disagreement among group members was the median proposal and not the best proposal. This aggregation rule explains why...

Professionals, like business consultants, have been described as crucial for modern knowledge-intensive organizations, but they are not always thought to be easy to manage or to attract. This might be due to a need for autonomy and commitment that is aimed more at the profession than at their...

This paper provides an analysis of the social consequences of people seeking to keep up with the Joneses. All individuals attempt to reach a higher rank than the Joneses, including the Joneses themselves. This attitude gives rise to an equilibrium in which all individuals have equal utilities...

We estimate the effects of peer benchmarking by institutional investors on asset prices. To identify trades purely due to peer benchmarking as separate from those based on fundamentals or private information, we exploit a natural experiment involving a change in a government-imposed...

The present paper aims to test a new model comparison methodology by calibrating and comparing three agent-based models of financial markets on the daily returns of 18 indices. The models chosen for this empirical application are the herding model of Gilli & Winker, its asymmetric version by...

This paper develops an agent-based model(ABM) to replicate financial instability, such as bubbles and crashes in asset markets, by introducing a simple idea of ‘heterogeneous expectation’ by which agents have different expectations about a ‘tipping point’ where they expect the price to...
