The European Union's Harmonized Index of Consumer Prices (HICP) is the single most important indicator of inflation used by the European Central Bank. This paper investigates the methodological foundations of the HICP. Sections 2 to 4 of the paper look at the theory of inflation indexes that could be used as central bank target indexes of inflation. A(More)
BACKGROUND Randomized trials comparing coronary artery bypass graft surgery (CABG) with percutaneous coronary interventions (PCIs) for patients with multivessel coronary disease (MVD) report similar long-term survival for CABG and PCI. These studies used a highly selected population of patients and providers, and their results may not be generalizable to(More)
Besides the theoretical (Alchian/Klein, 1973) case for including asset prices in measures of inflation, there is also a practical case, that some asset prices, notably housing, are closely associated with the main trends in inflation, and viàbubbles and busts' with output disturbances. Attempts to use the pure Alchian/Klein methodology in practice give(More)

The paper analyzes how the UNDP, the World Bank, and the IMF classify countries based on their level of development. These systems are found lacking in clarity with regard to their underlying rationale. The paper argues that a country classification system based on a transparent, data-driven methodology is preferable to one based on judgment or ad hoc(More)

Statistical offices use the matched models method to compile consumer price indices (CPIs) to measure inflation. Price collectors record the prices of a sample of models or varieties of selected products existing in period t, and then continue to record the prices of these same matched models in subsequent periods t+n. The matched models method is designed(More)
The immunotoxicity of methyl isocyanate (MIC) was evaluated in female B6C3F1 mice exposed via inhalation to 0, 1, or 3 ppm for 6 hr per day on 4 consecutive days. The antibody response to sheep erythrocytes and natural killer cell activity were found to be unaffected by MIC exposure. Although lymphoproliferative responses to mitogens were moderately(More)
BACKGROUND Several randomized trials comparing bare-metal stents to Drug-Eluting Stents (DES) have demonstrated a significant reduction in Target Vessel Revascularization (TVR) and Target Lesion Revascularization (TLR) exists with the use of drug-eluting stents, without compromising survival. These conclusions are based on restricted inclusion criteria for(More)
