In this paper we consider a panel data model with error components that are both spatially and time-wise correlated. The model blends specifications typically considered in the spatial literature with those considered in the error components literature. We introduce generalizations of the generalized moments estimators suggested in Kelejian and Prucha (1999. A generalized moments estimator for ...

The study presented involves several different contextual aspects and is the latest in a continuing series of exploratory experiments on information access behaviour in a multi-lingual context[1, 2]. This year’s interactive cross-lingual information access experiment was designed to measure three parameters we expected would affect the performance of users in cross-lingual tasks in languages in...

A whole-genome scan using single marker association was used to detect chromosome regions associated with seven female fertility traits in Finnish Ayrshire dairy cattle. The phenotypic data consisted of de-regressed estimated breeding values for 340 bulls which were estimated using a single trait model. Genotypes were obtained with the Illumina BovineSNP50 panel and a total of 35 630 informativ...

The study examines the role of the largest public works program in the world-the National Rural Employment Guarantee Scheme (NREGS) in buffering the negative effects of early childhood exposure to rainfall shocks on long-term health outcomes. Exploiting the spatial and temporal variation in NREGS coverage, the study estimates the extent to which nutritional insults in early childhood can be off...

905 National Tax Journal Vol. LIX, No. 4 December 2006 Abstract This paper considers what it might mean to describe the VAT as a “money machine,” tests whether it is one, and asks if it might consequently be wise not to adopt it. We fi nd broadly persuasive evidence, using panel data for the OECD, for a “weak form” of the money–machine hypothesis: that countries with a VAT raise more revenue th...

We develop a multi-factor stochastic volatility Libor model with displacement, where each individual forward Libor is driven by its own square-root stochastic volatility process. The main advantage of this approach is that, maturity-wise, each square-root process can be calibrated to the corresponding cap(let)vola-strike panel at the market. However, since even after freezing the Libors in the ...

In this paper we discuss tests for residual cross section dependence in nonlinear panel data models. The tests are based on average pair-wise residual correlation coefficients. In nonlinear models, the definition of the residual is ambiguous and we consider two approaches: deviations of the observed dependent variable from its expected value and generalized residuals. We show the asymptotic con...

Let be a stationary sequence of pair wise negative quadrant dependent random variables with survival function {,1}nXn?F(x)=P[X>x]. The empirical survival function ()nFx based on 12,,...,nXXX is proposed as an estimator for ()nFx. Strong consistency and point wise as well as uniform of ()nFx are discussed

Procedures controlling error rates measuring at least k false rejections, instead of at least one, are often desired while testing a large number of hypotheses. The k-FWER, probability of at least k false rejections, is such an error rate that has been introduced, and procedures controlling it have been proposed. Recently, Sarkar (2007) introduced an alternative, less conservative notion of err...
