This paper constructs the probability space underlying the random variable of any time dependent econometric specification. The construction links concrete economic activity, both perceived and recorded, and econometric formulations. Furthermore, it is argued that the probability events...

Inferences about the presence or absence of threshold type nonlinearities in TAR models are conducted within models whose lag length has been estimated in a preliminary stage. Typically the null hypothesis of linearity is then tested against a threshold alternative on which the estimated lag...

This paper focuses the development of the diagnostics for the perturbations of case-weights and explanatory variables (one or more) in a linear logistic regression model. The effect of specific perturbation scheme on the estimation of parameters is also assessed. In addition, the interpretation...

The influence of peer behavior on an individual's choices has received renewed interest in recent years. However, accurate measures of this influence are difficult to obtain. Standard reduced-form methods lead to upwardly biased estimates due to simultaneity, common shocks, and nonrandom peer...

This paper analyses the effect of labour taxes on Euro area unemployment. Empirical estimates obtained so far can be criticised as being spurious because the regressions generally lack non-measurable variables constituting the reservation wage that can possibly be non stationary. Here we...

This study examines the impact of telecommuting on passenger vehicle- miles traveled (VMT) through a multivariate time series analysis of aggregate nationwide data spanning 1966-1999 for all variables except telecommuting, and 1988-1998 for telecommuting. The analysis was conducted in two...

Censoring of outcomes (selection) is a common consequence of survey nonresponse and attrition in panels, and has received much attention. Joint censoring of regressors and outcomes is also common, but it has remained unexplored. This paper shows that the problem of identification when regressors...

The bootstrap is a method for estimating the distribution of an estimator or test statistic by resampling one's data. It amounts to treating the data as if they were the population for the purpose of evaluating the distribution of interest. Under mild regularity conditions, the bootstrap yields...

This paper investigates sample attrition in the Health and Retirement Study (HRS). We compare attrition behavior in two of the HRS cohorts: original HRS cohort and AHEAD cohort. We distinguish attrition due to death (passive attrition) from attrition due to other causes (active attrition),...

In this paper I attempt at answering to the following question: is modern culture affected by amcient cultural heritage? Are Archimedes and Qin Shi Huang, Cicero and Shakespeare, and the like, still intellectually alive? Do the Parthenon and the Temple of Heaven, and the like, significantly...
