Hierarchical crowdsourcing networks (HCNs) provide a useful mechanism for social mobilization. However, spontaneous evolution of the complex resource allocation dynamics can lead to undesirable herding behaviours in which a small group of reputable workers are overloaded while leaving other workers idle. Existing herding control mechanisms designed for typical crowdsourcing systems are not effe...

COVID-19 has caused not only unprecedented health crises but also economic among individuals across the world. White-collar (salaried-class) employees with a fixed salary face financial insecurity due to job loss, pay cuts and uncertainty in retaining job. This study examines behavior of Indian white-collar salaried-class investors their cognitive biases. In addition, mediating effect self-effi...

A major challenge within open markets is the ability to satisfy service demand with an adequate supply of service providers, especially when such demand may be volatile due to changing requirements, or fluctuations in the availability of services. Ideally, this supply and demand should be balanced; however, when consumer demand changes over time, and providers independently choose which service...

My research on bubbles started with my book “Asymmetric Information: Bubbles, Crashes, Technical Analysis and Herding” (Oxford University Press, 2001). The book surveys and critiques the literature on bubbles and herding in settings in which different investors hold different information. One conclusion of the book is that it is difficult to obtain bubbles in models in which all market particip...

BACKGROUND Gender differences in cardiovascular diseases (CVD) among the Sami have been reported previously. The aim of the present study was to investigate the incidence of and mortality from stroke, subarachnoid haemorrhage (SAH), and acute myocardial infarction (AMI) in the Swedish Sami population between 1985 and 2002, and to analyse the potential impact of income and level of education on ...

In this paper, we describe work that begins to address some of the issues related to developing an autonomous mobile robotic capability to assist humans with herding animals. A novel aspect of this work is the development of a capability to convey instructions to the robot via movements of a “toy human.” In this work, no other explicit form of communication from the human to the robot is requir...

We analyze herding behavior in the Chinese stock markets context of COVID-19 pandemic using cross-sectional absolute deviation (CSAD) model proposed by Chang et al. (2000) to detect time period between January 30, 2001, and June 12, 2020. consider prices for all firms listed (A-shares) on Shanghai Stock Exchange (SHSE) Shenzhen (SZSE) China. report presence during under study that becomes stron...

We show that the algorithm by Batra et al. (2012) to extract diverse M -solutions from a Conditional Random Field (called divMbest) takes exactly the form of a Herding procedure (Welling, 2009b), i.e. a deterministic dynamical system that produces a sequence of solutions that respect a set of observed moment constraints. This generalization enables us to invoke properties of Herding that show t...
