Abstract We analyse top income and wealth shares data, by conducting a robust estimation of trends, tests for structural breaks, determining persistence. include Anglo-Saxon countries, continental Europe Asian grouped under different percentiles deciles, spanning period that is at least close to century. find the almost all countries are characterised broken or level shifts. The preponderance t...

Consumer payment choice is based on heterogeneous preferences, availability, usage costs, and effective taxes. We examine the consequences of this consumption distribution, aggregate output, welfare shadow economy. analyze India’s sudden demonetization 86% cash in circulation with new notes gradually being replaced over next several months. The cost liquidity shock was equivalent to 1% owing sl...

Abstract We use high-quality UK panel data to document the extent that pre-existing labour market and financial inequalities were exacerbated by pandemic between April 2020 September 2021. Some worsened, others did not, in some cases, initial widening of was subsequently reversed. find no evidence an overall divergence outcomes gender. Initial changes for ethnic minorities young largely reverse...

Many researchers have used different auxiliary parameters such as coefficient of variation, kurtosis, skewness, quartiles, deciles etc., to improve the precision estimators under various sampling schemes. This paper suggested a class ratio with two known variable for estimation population means simple random sample without replacement (SRSWOR) using calibration weighting method. The calibrated ...

The aims of the present study were to determine compliance with current advice on vitamin D and to assess the influence of season, dietary intake, supplement use and deprivation on vitamin D status in pregnant mothers and newborns in the north of Scotland where sunlight exposure is low. Pregnant women (n 1205) and their singleton newborns were studied in the Aberdeen Maternity Hospital (latitud...

BACKGROUND Studies of geographic variation in hospitalizations commonly examine age- and gender-adjusted population-based hospitalization rates (ie, the numbers of persons hospitalized relative to what is expected given the age/gender distributions in the area population). OBJECTIVE To determine whether areas identified as extreme using population-based hospitalization rates remain extreme wh...

BACKGROUND Poisson regression is routinely used in occupational and environmental epidemiology. For typical Poisson regression analyses, person-time and events are tabulated by categorising predictor variables that were originally measured on a continuous scale. In order to estimate a dose-response trend, a researcher must decide how to categorise exposures and how to assign scores to exposure ...

AIMS To investigate the research productivity of all staff in chemical pathology. METHODS Chemical pathologists or biochemical scientists were identified from publicly available sources. All journals, their impact factors (IFs), and individual publications over the period of 1995 to 1999 were identified from electronic databases. Each publication was subclassified with respect to type of publ...

We introduce a new system of stochastic differential equations which models dependence market beta and unsystematic risk upon size, measured by capitalization. fit our model using size deciles data from Kenneth French’s library. This is somewhat similar to generalized volatility-stabilized models. The novelty work twofold. First, we take into account the difference between price total returns (...
