Cognitive biases and power in colective decision making
(Centro de Estudos em Finanças (GVcef), 2015)
The present work analysed the relationship between cognitive biases and power in a collective decision making context. Notably, the analyse of investment clubs indicated that power may affect confidence in a stock market ...
Inflation bias in Latin America
(2016)
This paper accesses the presence of inflation bias in major Latin American Economies over the past decade. Using a small-scale New Keynesian DSGE model and Bayesian Techniques, the time-varying neutral rate of interest is ...
Bias and size effects of price-comparison search engines: theory and experimental evidence
(Escola de Pós-Graduação em Economia da FGV, 2005-12-15)
We analyze the impact on consumer prices of the size and bias of price comparison search engines. In the context of a model related to Burdett and Judd (1983) and Varian (1980), we develop and test experimentally several ...
Unsupervised visual discrimination learning of complex stimuli: Accuracy, bias and generalization
(Elsevier, 2018-07)
Through same-different judgements, we can discriminate an immense variety of stimuli and consequently, they are critical in our everyday interaction with the environment. The quality of the judgements depends on familiarity ...
A discussion of bias in magnetotelluric responses
(Society of Exploration Geophysicists, 2009-07)
Magnetic-field noise biases magnitudes of magnetotelluric response functions such as resistivity, impedance, and the induction vector (tipper). This is particularly severe in the so-called dead band between about 1- and ...
A Bayesian bias updating procedure for automatic adaptation of soft sensors
(Pergamon-Elsevier Science Ltd, 2021-04)
Straightforward bias updating procedures for online adjustment of soft sensors (SS) are of interest for industrial processes in which quality or production variables cannot be measured online. This work proposes a Bayesian ...
