Predictivistic characterizations of multivariate student-t models
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003)
De Finetti style theorems characterize models (predictive distributions) as mixtures of the likelihood function and the prior distribution, beginning from some judgment of invariance about observable quantities. The ...
Skew normal measurement error models
(ELSEVIER INC, 2005)
In this paper we define a class of skew normal measurement error models, extending usual symmetric normal models in order to avoid data transformation. The likelihood function of the observed data is obtained, which can ...
Decision theory applied to a linear panel data model
(Wiley-Blackwell Publishing, Inc, 2009-01)
This paper applies some general concepts in decision theory to a linear panel data model. A simple version of the model is an autoregression with a separate intercept for each unit in the cross section, with errors that ...

Feasible analysis, randomness, and base invariance
(Springer, 2015-04)
We show that polynomial time randomness of a real number does not depend on the choice of a base for representing it. Our main tool is an ‘almost Lipschitz’ condition that we show for the cumulative distribution function ...
A search-theoretic explanation for the negative correlation between labor income and impatience
(Escola de Pós-Graduação em Economia da FGV, 2004-08-01)
Lawrance (1991) has shown, through the estimation of consumption Euler equations, that subjective rates of impatience (time preference) in the U.S. are three to Öve percentage points higher for households with lower average ...
