We propose a simple and flexible reduced-form econometric approach to estimate gravity models in the short and the long run. The theoretical lens for interpreting our methods amends the canonical Lucas-Prescott adjustment formulation to allow for time-interval-varying...

Non-parametric gravity as defined in this paper encompasses previous parametric forms. The model generates non-parametric sufficient statistics for arbitrage gains from trade and terms of trade, and a non-parametric elasticity of terms of trade with respect to supply. For world manufacturing...

Tax legislation since the early 1980s has significantly altered Average Tax Rates (ATRs) across the income distribution in the United States. Using a consistently defined ATR series for the years 1979--2003, this study finds that the 1980s reduced ATRs for all taxpayers except those in the...
