Accounting for Pairwise Heterogeneity in Bilateral Trade Flows: A Stochastic Varying Coefficient Gravity Model [PDF]
This paper suggests an alternative way for estimating the gravity equation that takes into consideration country-pair heterogeneity in bilateral trade flows. Specifically, a stochastic varying coefficient gravity model based on Hildreth and Houck’s (1968)

Geometrizing gravity and vice-versa: the force of a formulation [PDF]
, 2009 It is well-known that Newton’s theory of gravity, commonly held to describe a gravitational force, can be recast in a geometrical form: Newton- Cartan theory.

Geometric duality between effective field theories. Part I. Scattering amplitudes
Journal of High Energy PhysicsWe propose a novel type of duality that connects a sequence of well-known theories with even-multiplicity scalar amplitudes: it relates the Yang-Mills theory coupled to a specific scalar matter sector to the nonlinear sigma model on a symmetric coset ...

Gravity Equation and Trade Agreements: A Different Econometric Approach [PDF]
This paper is aimed at multiplicatively estimating the parameters of the gravity equation by using the Poisson Pseudo-Maximum-Likelihood (PPML) estimator, and taking heteroskedasticity into account at the same time.

Upgrade of the Gravity Database [PDF]
, 2011 A project was initiated in 2009 to upgrade the MGS gravity data by (1) re-positioning the pre-existing stations and re-reducing these, (2) addition of the missing archival information to the pre-existing database, and (3) incorporating data that have ...

Perturbations of plane waves and quadratic quasinormal modes on the lightring
Journal of High Energy PhysicsWe study second order gravitational perturbations on plane wave spacetimes from both the metric and curvature perturbation points of view. For the former, we explicitly use the isometries of the background to introduce tensor oscillator harmonics, which ...
