The largely dominant meritocratic paradigm of highly competitive Western cultures is rooted on the belief that success due mainly, if not exclusively, to personal qualities such as talent, intelligence, skills, efforts or risk taking. Sometimes, we are willing admit a certain degree luck could also play role in achieving significant material success. But, matter fact, it rather common underestimate importance external forces individual successful stories. It very well known intelligence...
We propose a novel data-driven framework for assessing the a-priori epidemic risk of geographical area and identifying high-risk areas within country. Our index is evaluated as function three different components: hazard disease, exposure vulnerability its inhabitants. As an application, we discuss case COVID-19 outbreak in Italy. characterize each twenty Italian regions by using available historical data on air pollution, human mobility, winter temperature, housing concentration, health...
In this paper we explore the specific role of randomness in financial markets, inspired by beneficial noise many physical systems and previous applications to complex socio-economic systems. After a short introduction, study performance some most used trading strategies predicting dynamics markets for different international stock exchange indexes, with goal comparing them completely random strategy. respect, historical data FTSE-UK, FTSE-MIB, DAX, S & P500 indexes are taken into account...
Building on similarities between earthquakes and extreme financial events, we use a self-organized criticality-generating model to study herding avalanche dynamics in markets. We consider community of interacting investors, distributed small-world network, who bet the bullish (increasing) or bearish (decreasing) behavior market which has been specified according S 500 historical time series. Remarkably, find that size herding-related avalanches can be strongly reduced by presence relatively...
We present a financial market model, characterized by self-organized criticality, that is able to generate endogenously realistic price dynamics and reproduce well-known stylized facts. consider community of heterogeneous traders, composed chartists fundamentalists, focus on the role informative pressure participants, showing how spreading information, based imitative behavior, drives contagion causes fragility. In this model imitation not intended as change in agent's group origin, but...
Although interdisciplinarity is often touted as a necessity for modern research, the evidence on relative impact of sectorial versus to interdisciplinary science qualitative at best. In this paper we leverage bibliographic data set American Physical Society quantify role in physics, and that talent luck achieving success scientific careers. We analyze period 30 years (1980-2009) tagging papers their authors by means Physics Astronomy Classification Scheme (PACS), show some degree quite...
Abstract In this paper we analyse the effects of information flows in cryptocurrency markets. We first define a trading network, i.e. network made using cryptocurrencies as nodes and Granger causality among their weekly log returns links, later its evolution over time. particular, with reference to years 2020 2021, study logarithmic US dollar price both pairwise high-order statistical dependencies, quantified by O-information, respectively. With former, find that it shows peaks...
The Brain Drain phenomenon is particularly heterogeneous and characterized by peculiar specifications. It influences the economic fundamentals of both country origin host one in terms human capital accumulation. Here, brain drain considered from a microeconomic perspective: more precisely we focus on individual rational decision to return, referring it social owned worker. presented model compares utility levels justify agent's migration conduct simulate several scenarios within...
In this paper, making use of recent statistical physics techniques and models, we address the specific role randomness in financial markets, both at micro macro level. particular, review some results obtained about effectiveness random strategies investment, compared with most used trading for forecasting behaviour real indexes. We also push forward our analysis by means a self-organised criticality model, able to simulate avalanches communities different network topologies, where...
Purpose Discrimination and hostility in the workplace prevents homosexual workers from performing their core functions on job. Moreover, it introduces unnecessary costs by increasing absenteeism, lowering productivity, fostering a less motivated, entrepreneurial, committed workforce. By means of an agent-based model, authors simulated effects unemployment rates sexual orientation (SO) disclosure workplaces. The tested workers’ utility, level job satisfaction segregation. results show...
While wealth distribution in the world is highly skewed and heavy-tailed, human talent - as majority of individual features normally distributed. In a recent computational study by Pluchino et al [Talent vs luck: The role randomness success failure, Adv. Complex Syst. 21 (03-04) (2018) 1850014], it has been shown that combined effects both random external factors (lucky unlucky events) multiplicative dynamics capital accumulation are able to clarify this apparent contradiction. We introduce...
It is a widespread belief that success mainly due to innate qualities rather than external forces. This particularly true in sports competitions, where individual talent usually considered the main, if not only, ingredient reach success. In this study, we explore limits of by quantifying relative weight and chance fencing, combat sport involving weapon, with help both real data agent-based simulations. Fencing competitions are structured as direct elimination tournaments, randomness...
