Given the different income inequalities between rural, urban and metropolitan areas in Paraguay, the standard Roy model predicts the possibility that a selection bias of rural metropolitan migrants exists. Based on an extended Roy model, which allows for correlation between labor market characteristics and moving cost, I use a switching regression model to evaluate if migrants from rural to met...

Context: A potentially important, but neglected, reason for effort overruns in software projects is related to selection bias. Selection bias–induced effort overruns occur when proposals are more likely to be accepted and lead to actual projects when based on effort estimates that are too low rather than on realistic estimates or estimates that are too high. The effect of this bias may be parti...

The Rosse-Panzar revenue test for competitive conditions in banking is based on observation of the impact on bank revenue of variation in factor input prices. We identify the implications for the H-statistic of misspecification bias in the revenue equation, arising when adjustment towards market equilibrium is partial and not instantaneous. In simulations, fixed effects estimation produces a me...

Statistical learning (SL) is increasingly invoked as a set of general-purpose mechanisms upon which language learning is built during infancy and childhood. Here we investigated the extent to which SL is related to adult language processing. In particular, we asked whether SL proclivities towards relations that are more informative of English are related to efficiency in reading English sentenc...

In urban areas, buildings are often used as landmarks for localization. Reliable and efficient recognition of buildings is crucial for enabling this functionality. Motivated by the applications which would enhance visual localization and navigation capabilities we propose in this paper a hierarchical approach for building recognition. In the first recognition stage the model views are indexed b...

The observation of distant supernovae shows that the light of supernovae Ia is dimmer than it would be in a decelerating Universe. Several effects might be responsible for this phenomenon: cosmological constant, evolution of supernovae, selection bias, gravitational lensing, intergalactic dust, and influence of inhomogeneous distribution of matter on light propagation. All these effects but the...

This paper investigates the impact of referee behaviour on the quality and efficiency of peer review. We focused especially on the importance of reciprocity motives to ensure cooperation between everyone involved. We modelled peer review as a process based on knowledge asymmetries and subject to evaluation bias. We built various simulation scenarios where we tested interaction conditions and ma...

Asymptotic properties of model selection criteria for high-dimensional regression models are studied where the dimension of covariates is much larger than the sample size. Several sufficient conditions for model selection consistency are provided. Non-Gaussian error distributions are considered and it is shown that the maximal number of covariates for model selection consistency depends on the ...
