This paper investigates forecasts of US in#ation at the 12-month horizon. The starting point is the conventional unemployment rate Phillips curve, which is examined in a simulated out-of-sample forecasting framework. In#ation forecasts produced by the Phillips curve generally have been more accurate than forecasts based on other macroeconomic variables, including interest rates, money and commo...

Chemical engineering deals with synthesis of various chemicals in economical and efficient manner. Raw material is important aspect for cost effective manufacturing of chemicals. Biological methods for syntheis consume less energy and are very economical for production of chemicals such as ethanol, acetic acid, citric acid, lactic acid etc. Waste solid materials such as molassis, fruit peels, w...

In supersymmetric theories a eld can develop a vacuum expectation value M 10GeV, even though its mass m is of order 10 to 10GeV. The nite temperature in the early Universe can hold such a eld at zero, corresponding to a false vacuum with energy density V0 m 2 M . When the temperature falls below V 1=4 0 , the thermal energy density becomes negligible and an era of thermal in ation begins. It en...

The so-called Fed model postulates that the dividend or earnings yield on stocks should equal the yield on nominal Treasury bonds, or at least that the two should be highly correlated. In US data there is indeed a strikingly high time series correlation between the yield on nominal bonds and the dividend yield on equities. This positive correlation is often attributed to the fact that both bond...

The union of high-energy particle theories and gravitation often gives rise to an evolving strength of gravity. The standard picture of the earliest universe would certainly deserve revision if the Planck mass, which de nes the strength of gravity, varied. A notable consequence is a gravity-driven, kinetic in ation. Unlike standard in ation, there is no potential nor cosmological constant. The ...

a study published in the previous issue of Critical Care, Gonçalves and colleagues [1] observed a 33% reduction in re-intubation rate in the study group, due to eff ective management of bronchial secretions. Current evidence favors early implementation of noninvasive mechanical ventilation (NIV) in the post-extubation period to reduce re-intubation, especially in patients with hypercapnic respi...

This paper examines the implications of on-the-job search for both short-run dynamics of in‡ation and long-run welfare costs of in‡ation in a sticky price model with labour market search frictions. Both unemployed workers and workers with bad jobs can search. Firms can adjust labour at both intensive and extensive margins. On-the-job search gives rise a strong propagation of monetary policy sho...

In this paper we examine whether or not the NKM is …t for the purpose of providing a suitable basis for the conduct of monetary policy through in‡ation targeting. We focus on a number of issues: the dynamic response of in‡ation to interest rates in a theoretical NKM under discretion and commitment to a Taylor rule; the implications for the speci…cation of the New Keynesian Phillips equation of ...
