Abstract This study investigates the empirical validity of the variability hypothesis in Turkey for the period of February 2005-November 2015, by using cross-sectional relative price data and by focusing on the assumptions of linearity and stability. The linearity assumption between the two variables is ensured by estimating quadratic regression equation. The assumption of stability is secur...

heart failure (hf) is a common disease with high health care costs and high mortality rate knowledge of the health-related quality of life (qol) outcomes of hf may guide decision making and be useful in assessing new therapies for population. yet little is known about qol of hf patients in iran. objectives: to assess health related qol of patients with hf with two different instrument and to co...

CONTEXT In India, 14% of the population use smoked tobacco products. Increasing prices of these products is one of the measures to curb their consumption. AIMS This study analyzes "unit price" and "daily consumption" of cigarettes and bidis and investigates their relation with each other. SETTINGS AND DESIGN A cross-sectional survey was conducted in four states of India (Bihar, West Bengal,...

Relative price variability leads to inefficiencies in the allocation of resources that reduce real income (Fischer, 1981). Given the costs associated with relative price variability, the relation between inflation and relative price variability has been extensively researched and a positive relation between the two is documented for many countries and for varying time periods. Investigating the...

This paper presents out-of-sample inflation forecasting results based on relative price variability and skewness. It is demonstrated that forecasts on long horizons of 1.5-2 years are significantly improved if the forecast equation is augmented with skewness. JEL: E17, E31, C43

This paper develops a stochastically-based method of measuring core inflation. The approach exploits the persistent tendency towards high kurtosis evident in the cross-sectional distribution of consumer price changes evident in New Zealand and elsewhere. High kurtosis makes the sample mean a less efficient and less robust estimator of the population, or underlying, mean price change than is an ...

To establish comprehensive criteria for detecting restenosis and remodeling, inter- and intraobserver reproducibility of quantitative arteriography in the analysis of 20 lesions immediately after and 6 months after percutaneous transluminal coronary angioplasty (PTCA) were assessed. Geometric single-plane (minimum, maximum, mean diameter and percent diameter stenosis), biplane (absolute and rel...
