Although the economic literature on the optimal management of bank excess reserves is age-old and large, here we suggest a fresh, more practical approach based on queuing theory.

Applied econometricians tend to show a long neglect for the proper frequency to be considered while sampling the time series data. The present study shows how spectral analysis can be usefully employed to fix this problem. The case is illustrated with ultra-high-frequency data and daily prices...

The relative efficiency of financial markets can be evaluated using algorithmic complexity theory. Using this approach we detect decreases in efficiency rates of the major stocks listed on the Sao Paulo Stock Exchange in the aftermath of the 2008 financial crisis.

Group thinking is the notion that natural selection favors what is good for the group or the species, not for the individual. Most mainstream evolutionary biology rejects this idea and natural selection is viewed as working on the individual’s genes to promote their own survival and...

Why not set up some public-service robot traders to counteract the behavior of traders when it snowballs into extreme moves? I show a blueprint of how this can be accomplished taking advantage of the theory of complex systems.

This essay asserts that the mutual gains accruing from the exchange of goods between siblings can moderate the famous parent-offspring conflict, an issue of interest in evolutionary biology. The rationale combines basic concepts of economics and behavioral genetics, and fills in the gaps of...

Undergraduates were given a battery of psychological tests to gauge their degree of antisocial personality traits (psychopathy, Machiavellianism and nihilism). The students also responded to questionnaires to assess their attitudes toward risk and intertemporal choice. Biological attributes of...

We assess the psychophysiological characteristics underlying the disposition effect and find that subjects showing greater disposition effect are those who sweat more and present lower body temperature and heart rate.

We replicate the Stanford marshmallow experiment with a sample of 141 preschoolers and find a correlation between lack of self-control and 2D:4D digit ratio. Children with low 2D:4D digit ratio are less likely to delay gratification. Low 2D:4D digit ratio may indicate high fetal testosterone. If...
