Fiscal Shocks and the Exchange Rate in a Generalized Redux Model

This paper studies how the interaction between the monetary policy regime and the degree of home bias in public consumption affects the exchange- rate response to fiscal shocks in a generalized version of the Redux model of Obstfeld and Rogoff (1995). We show that the joint presence of home bias in public consumption and endogenous monetary policy overturns the result of the Redux model implying an exchange-rate appreciation in response to an expansionary fiscal shock

Pensions and Intertemporal Choice: Evidence from the U.S. Military

SSRN-id2383874We study a choice made by over 20,000 U.S. military personnel annually between the High-3 and Redux retirement plans. Compared to High-3, Redux offers a $30,000 current lump sum payment in exchange for lower future annuity payments. Despite break-even discount rates between 10chose Redux. The likelihood of choosing Redux is decreasing with the break-even discount rate and is related to individual demographics. The implied personal discount rates from this choice are around 9.2Offering this choice has already saved the government over$2 billion in future retirement payments

Threshold Factorization Redux

We reanalyze the factorization theorems for Drell-Yan process and for deep inelastic scattering near threshold, as constructed in the framework of the soft-collinear effective theory (SCET), from a new, consistent perspective. In order to formulate the factorization near threshold in SCET, we should include an additional degree of freedom with small energy, collinear to the beam direction. The corresponding collinear-soft mode is included to describe the parton distribution function (PDF) near threshold. The soft function is modified by subtracting the contribution of the collinear-soft modes in order to avoid double counting on the overlap region. As a result, the proper soft function becomes infrared finite, and all the factorized parts are free of rapidity divergence. Furthermore, the separation of the relevant scales in each factorized part becomes manifest. We apply the same idea to the dihadron production in $e^+ e^-$ annihilation near threshold, and show that the resultant soft function is also free of infrared and rapidity divergences.Comment: 20 pages, 2 figures; matches published versio

Searching for Apery-Style Miracles [Using, Inter-Alia, the Amazing Almkvist-Zeilberger Algorithm]

Roger Apery's seminal method for proving irrationality is "turned on its head" and taught to computers, enabling a one second redux of the original proof of zeta(3), and many new irrationality proofs of many new constants, alas, none of them is both famous and not-yet-proved-irrational.Comment: 16 pages.

SSTRED: A data-processing and metadata-generating pipeline for CHROMIS and CRISP

We present a data pipeline for the newly installed SST/CHROMIS imaging spectrometer, as well as for the older SST/CRISP spectropolarimeter. The aim is to provide observers with a user-friendly data pipeline, that delivers science-ready data with the metadata needed for archival. We generalized the CRISPRED data pipeline for multiple instruments and added metadata according to recommendations worked out as part of the SOLARNET project. We made improvements to several steps in the pipeline, including the MOMFBD image restoration. A part of that is a new fork of the MOMFBD program called REDUX, with several new features that are needed in the new pipeline. The CRISPEX data viewer has been updated to accommodate data cubes stored in this format. The pipeline code, as well as REDUX and CRISPEX are all freely available through git repositories or web download. We derive expressions for combining statistics of individual frames into statistics for a set of frames. We define a new extension to the World Coordinate System, that allow us to specify cavity errors as distortions to the spectral coordinate.Comment: Draf
