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...

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...

Many facts are learned through the intermediation of individuals with special access to information, such as law enforcement officers, employees with a security clearance, or experts with specific knowledge. This paper considers whether societies can learn about such facts when information is...

Data Science looks at raw numbers and informational objects created by different disciplines. The Digital Society creates information and numbers from many scientiHic disciplines. The amassment of data though makes is hard to Hind structures and requires a skill full analysis of this massive raw...

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...

Concentrating on speculative flow rather than stock demand, the paper puts forward a deterministic continuous-time model of the equity market that is compatible with a growing and inflationary economy. Instead of the systematically rising equity price, the central state variable in now Tobin's...

This paper presents the results from a 2.3 million person field experiment that varies whether or not a job seeker sees the number of applicants for a job posting on a large job posting website, LinkedIn. This intervention increases the likelihood that a person will finish an application by...

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...

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...

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...

We study perfect Bayesian equilibria of a sequential social learning model in which agents in a network learn about an underlying state by observing neighbors' choices. In contrast with prior work, we do not assume that the agents' sets of neighbors are mutually independent. We introduce a new...

This paper investigates the role of food self-provisioning for the intake of macro- and micronutrients of households in Mongolia. Our analysis is based on rich household survey data that collected food consumption through consumption diaries. We analyze nutritional outcomes within and across the...
