We correct for endogeneity bias in fixed-effects estimates of workerand firmspecific earnings heterogeneity using longitudinal linked employer-employee data. Realized job assignments may be determined by unobservable components of earnings. We exploit the relational structure of the data to model the evolution of the matched data as an evolving bipartite graph in a Bayesian latent class framewo...

We construct a dynamic panel error correction model of the Australian labour market using macroeconomic data across seven states and 27 years. Using panel cointegration tests, and fully modified OLS estimates, we test 3 competing long run hypotheses: real wage-productivity relation; real wage-marginal disutility relation; and the wage curve hypothesis. We find evidence to prefer the first. The ...

Reliance on self-rated health to proxy medical need can bias estimation of education-related inequity in healthcare utilization. We correct this bias both by instrumenting self-rated health with objective health indicators and by purging self-rated health of reporting heterogeneity that is identified from health vignettes. Using data on elderly Europeans, we find that instrumenting self-rated h...

The magnitude of the value of a statistical life (VSL) is critical to the evaluation of many health and safety initiatives. To date, the large and rigorous VSL research literature has not explicitly accommodated publication selectivity bias (i.e., the reduced probability that insignificant or negative VSL values are reported). This study demonstrates that doing so is essential. For studies that...

Dioxin-related compounds are associated with teratogenic and mutagenic risks in laboratory animals, and result in adverse pregnancy outcomes. However, there were inconsistent results in epidemiology studies. In view of this difference, we conducted a systematic review and meta-analysis to examine this association and to assess the heterogeneity among studies. Comprehensive literature searches w...

Adolescent Idiopathic Scoliosis (AIS) is the most common form of Idiopathic Scoliosis (IS) with a prevalence of 3% 5.2% among children [1]. Disease progression and sequelae depend on the location, severity, and rate of progression of the curve. Curves tend to progress most rapidly during growth phases [1,2]. Treatments and are focused on early bracing to stem curve progression and surgical curv...

This article reports Monte Carlo results on the simulated maximum likelihood estimation of discrete panel statistical models. Among them are Markov, Generalized Poly, Renewal, and Habit Persistence Models with or without unobserved heterogeneity and serially correlated disturbances. We investigate statistical properties and computational performance of simulated maximum likelihood methods and a...

MOTIVATION Extensive DNA sequencing of tumor and matched normal samples using exome and whole-genome sequencing technologies has enabled the discovery of recurrent genetic alterations in cancer cells, but variability in stromal contamination and subclonal heterogeneity still present a severe challenge to available detection algorithms. RESULTS Here, we describe publicly available software, Sh...

this study aimed at comparing the impact of two types of teacher feedback on iranian efl learners’ writing ability and their verb tense consistency in l2 writing. following the administration of a standardized language proficiency test (preliminary english test), sixty-two participants were selected and were randomly assigned to the control (direct-only correction) and experimental (direct meta...
