Tidal Inflation Reconciles Low-density Sub-Saturns with Core Accretion

Two Transiting Low Density Sub-saturns from K2

We report the discovery and confirmation of K2-24 b and c, two sub-Saturn planets orbiting a bright (V= 11.3), metal-rich ([Fe/H]= 0.42±0.04 dex) G3 dwarf in the K2 Campaign 2 field. The planets are 5.68±0.56 RÅ and 7.82±0.72 RÅ and have orbital periods of 20.8851±0.0003 days and 42.3633±0.0006 days, near the 2:1 mean-motion resonance. We obtained 32 radial velocities with Keck/HIRE...

Pce Inflation and Core Inflation

This paper investigates the forecasting accuracy of the trimmed mean inflation rate of the Personal Consumption Expenditure (PCE) deflator. Earlier works have examined the forecasting ability of limited-influence estimators (trimmed means and the weighted median) of the Consumer Price Index but none have compared the weighted median and trimmed mean of the PCE. Also addressed is the systematic ...

Core Inflation and Trend Inflation June 2015

An important input to monetary policymaking is estimating the current level of inflation. This paper examines empirically whether the measurement of trend inflation can be improved by using disaggregated data on sectoral inflation to construct indexes akin to core inflation but with a time-varying distributed lags of weights, where the sectoral weight depends on the timevarying volatility and p...

Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary

Core inflation and monetary policy

What are the implications of targeting different measures of inflation? We extend a basic theoretical framework of optimal monetary policy under inflation targeting to include several components of CPI inflation, and analyze the implications of using different measures of inflation as target variable— core inflation, CPI excluding interest rates, and headline CPI inflation. Our main results are...
