Perché le teorie liberali moderate non devono temere la behavioral economics o la heuristics and biases psychology
2021
In this article I will explain the content of soime cognitive bias and the content of liberal theories. I will argument that people commit less cognitive errors than Conly and others think. Secondly, some behaviours that Conly and others think are cognitive bias are not. Finally, it is clear in the studies of Kahneman and Tversky that the majority of cognitive bias are not incorrigibles (in the correct sense of this word)
Etica della popolazione. Sul ruolo delle intuizioni morali
2019
In questa tesi vengono analizzati i principali argomenti per risolvere i paradossi dell'etica della popolazione (dibattito di etica normativa). Gli argomenti vengono suddivisi in due stili rispondenti a regole diverse. Segue un'analisi sul piano metodologico dei due stili morali, presentati come due modi di intendere la ricerca rawlsiana di un equilibrio riflessivo. Dopo aver messo a fuoco le differenze principali tra questi due stili viene avanzata la tesi secondo la quale uno di essi sia il metodo di indagine normativa proprio del Soggettivismo (tesi per cui le ragioni che abbiamo per agire dipendono dalle nostre proattitudini teliche). In this work the main arguments that have been put f…
Maximizing versus satisficing in the digital age: Disjoint scales and the case for “construct consensus”
2018
Abstract A question facing us today, in the new and rapidly evolving digital age, is whether searching for the best option – being a maximizer – leads to greater happiness and better outcomes than settling on the first good enough option found – or “satisficing.” Answers to this question inform behavioural insights to improve well-being and decision-making in policy and organizational settings. Yet, the answers to this fundamental question of measurement of the happiness of a maximizer versus a satisficer in the current psychological literature are: 1) conflicting; 2) anchored on the use of the first scale published to measure maximization as an individual-difference, and 3) unable to descr…
Volatility co-movements: a time scale decomposition analysis
2014
In this paper we are interested in detecting contagion from US to European stock market volatilities in the period immediately after the Lehman Brothers’ collapse. The analysis, based on a factor decomposition of the covariance matrix of implied and realized volatilities, is carried for different sub-samples (identified as normal and crisis periods) and across different (high) frequency bands. In particular, the analysis is split in two stages. In the first stage, we retrieve the time series of wavelet coefficients for each volatility series for high frequency scales, using the Maximal Overlapping Discrete Wavelet transform and, in a second stage, we apply Maximum Likelihood for a factor de…
A Generalized Missing-Indicator Approach to Regression with Imputed Covariates
2011
We consider estimation of a linear regression model using data where some covariate values are missing but imputations are available to fill in the missing values. This situation generates a tradeoff between bias and precision when estimating the regression parameters of interest. Using only the subsample of complete observations does not cause bias but may imply a substantial loss of precision because the complete cases may be too few. On the other hand, filling in the missing values with imputations may cause bias. We provide the new Stata command gmi, which handles such tradeoff by using either model reduction or Bayesian model averaging techniques in the context of the generalized miss…

Unreliability of the dot probe task
2005
The dot probe task is a widely used measure of attention allocation to threatening stimuli. The present two studies examine the reliability of different versions of this task using words as well as pictures as stimulus material. Estimates of both internal consistency and retest reliability over one week lead to the conclusion that the dot probe task is a completely unreliable measure of attentional allocation in non‐clinical samples. This unreliability may explain the inconsistent findings for the dot probe task as reported in the literature. Copyright © 2005 John Wiley & Sons, Ltd.
The mystery of the Polish soul. B. W. Johnson's effectà rebours
1996
Studies conducted in Poland replicated a not very-well known effect discovered by B. W. Johnson (1937). In his study students estimated their mood on several successive days each time comparing it to the mood they usually have. The results revealed a peculiar positive bias in that the students usually defined their mood as 'better than usual'. Johnson's study was replicated in Poland, where demonstration of optimism is not a cultural norm. The results suggest that Polish subjects 'usually define their mood as worse than usual'. The generalization and limitation of this negative bias is discussed in the light of the Pollyanna Principle and related empirical studies involving Polish subjects.
